8 1 Safety precautions 1.1 Safety icons Explanation Danger for life Warning Important note 1.2 Safety precautions, general General precautions 1. The operator must employ safe working practices and observe all related work safety requirements and regulations. 2. If any of the following statements does not comply with the applicable legislation, the stricter of the two shall apply. 3. Installation, operation, maintenance and repair work must only be performed by authorized, trained, specialized personnel. 4. The compressor is not considered capable of producing air of breathing quality. For air of breathing quality, the compressed air must be adequately purified according to the applicable legislation and standards. 5. Before any maintenance, repair work, adjustment or any other non-routine checks, stop the compressor, press the emergency stop button, switch off the voltage and depressurize the compressor. In addition, the power isolating switch must be opened and locked. On units powered by a frequency converter, wait 10 minutes before starting any electrical repair. If the machine is equipped with an automatic restart after voltage failure function and if this function is active, be aware that the machine will restart automatically when the power is restored if it was running when the power was interrupted! 6. Never play with compressed air. Do not apply the air to your skin or direct an air stream at people. Never use the air to clean dirt from your clothes. When using the air to clean equipment, do so with extreme caution and wear eye protection. 7. The owner is responsible for maintaining the unit in safe operating condition. Parts and accessories shall be replaced if unsuitable for safe operation. 8. It is not allowed to walk or stand on the unit or on its components

9 1.3 Safety precautions during installation All responsibility for any damage or injury resulting from neglecting these precautions, or non observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. Precautions during installation 1. The machine must only be lifted using suitable equipment in accordance with the applicable safety regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to dwell or stay in the risk zone under a lifted load. Lifting acceleration and deceleration must be kept within safe limits. Wear a safety helmet when working in the area of overhead or lifting equipment. 2. The unit is designed for indoor use. If the unit is installed outdoors, special precautions must be taken; consult your supplier. 3. Place the machine where the ambient air is as cool and clean as possible. If necessary, install a suction duct. Never obstruct the air inlet. Care must be taken to minimize the entry of moisture at the inlet air. 4. Any blanking flanges, plugs, caps and desiccant bags must be removed before connecting the pipes. 5. Air hoses must be of correct size and suitable for the working pressure. Never use frayed, damaged or worn hoses. Distribution pipes and connections must be of the correct size and suitable for the working pressure. 6. The aspirated air must be free of flammable fumes, vapors and particles, e.g. paint solvents, that can lead to internal fire or explosion. 7. Arrange the air intake so that loose clothing worn by people cannot be sucked in. 8. Ensure that the discharge pipe from the compressor to the aftercooler or air net is free to expand under heat and that it is not in contact with or close to flammable materials. 9. No external force may be exerted on the air outlet valve; the connected pipe must be free of strain. 10. If remote control is installed, the machine must bear a clear sign stating: DANGER: This machine is remotely controlled and may start without warning. The operator has to make sure that the machine is stopped and depressurized and that the electrical isolating switch is open, locked and labelled with a temporary warning before any maintenance or repair. As a further safeguard, persons switching on or off remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the start equipment. 11. Air-cooled machines must be installed in such a way that an adequate flow of cooling air is available and that the exhausted air does not recirculate to the compressor air inlet or cooling air inlet. 12. The electrical connections must correspond to the applicable codes. The machines must be earthed and protected against short circuits by fuses in all phases. A lockable power isolating switch must be installed near the compressor. 13. On machines with automatic start/stop system or if the automatic restart function after voltage failure is activated, a sign stating "This machine may start without warning" must be affixed near the instrument panel. 14. In multiple compressor systems, manual valves must be installed to isolate each compressor. Non-return valves (check valves) must not be relied upon for isolating pressure systems. 15. Never remove or tamper with the safety devices, guards or insulation fitted on the machine. Every pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure must be protected by a pressure relieving device or devices as required. 16. Piping or other parts with a temperature in excess of 70 C (158 F) and which may be accidentally touched by personnel in normal operation must be guarded or insulated. Other high temperature piping must be clearly marked

10 17. For water-cooled machines, the cooling water system installed outside the machine has to be protected by a safety device with set pressure according to the maximum cooling water inlet pressure. 18. If the ground is not level or can be subject to variable inclination, consult the manufacturer. Also consult following safety precautions: Safety precautions during operation and Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine. 1.4 Safety precautions during operation All responsibility for any damage or injury resulting from neglecting these precautions, or non observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. Precautions during operation 1. Never touch any piping or components of the compressor during operation. 2. Use only the correct type and size of hose end fittings and connections. When blowing through a hose or air line, ensure that the open end is held securely. A free end will whip and may cause injury. Make sure that a hose is fully depressurized before disconnecting it. 3. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment. 4. Never operate the machine when there is a possibility of taking in flammable or toxic fumes, vapors or particles. 5. Never operate the machine below or in excess of its limit ratings. 6. Keep all bodywork doors shut during operation. The doors may be opened for short periods only, e.g. to carry out routine checks. Wear ear protectors when opening a door. On compressors without bodywork, wear ear protection in the vicinity of the machine. 7. People staying in environments or rooms where the sound pressure level reaches or exceeds 80 db(a) shall wear ear protectors. 8. Periodically check that: All guards are in place and securely fastened All hoses and/or pipes inside the machine are in good condition, secure and not rubbing No leaks occur All fasteners are tight All electrical leads are secure and in good order Safety valves and other pressure relief devices are not obstructed by dirt or paint Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in good repair, free of wear or abuse Air cooling filters of the electrical cabinet are not clogged 9. If warm cooling air from compressors is used in air heating systems, e.g. to warm up a workroom, take precautions against air pollution and possible contamination of the breathing air. 10. On water-cooled compressors using open circuit cooling towers, protective measures must be taken to avoid the growth of harmful bacteria such as Legionella pneumophila bacteria

11 11. Do not remove any of, or tamper with, the sound-damping material. 12. Never remove or tamper with the safety devices, guards or insulations fitted on the machine. Every pressure vessel or auxiliary installed outside the machine to contain air above atmospheric pressure shall be protected by a pressure relieving device or devices as required. 13. Yearly inspect the air receiver. Minimum wall thickness as specified in the instruction book must be respected. Local regulations remain applicable if they are more strict. Also consult following safety precautions: Safety precautions during installation and Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine. 1.5 Safety precautions during maintenance or repair All responsibility for any damage or injury resulting from neglecting these precautions, or non observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. Precautions during maintenance or repair 1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.). 2. Use only the correct tools for maintenance and repair work. 3. Use only genuine spare parts. 4. All maintenance work shall only be undertaken when the machine has cooled down. 5. A warning sign bearing a legend such as "Work in progress; do not start" shall be attached to the starting equipment. 6. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote start equipment. 7. Close the compressor air outlet valve and depressurize the compressor before connecting or disconnecting a pipe. 8. Before removing any pressurized component, effectively isolate the machine from all sources of pressure and relieve the entire system of pressure. 9. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against toxic vapours of cleaning liquids. 10. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts and exposed openings with a clean cloth, paper or tape. 11. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely purged, e.g. by steam cleaning, before carrying out such operations. Never weld on, or in any way modify, pressure vessels. 12. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has elapsed; this to avoid the risk of spontaneous ignition of the oil vapour when air is admitted. 13. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc. 14. Make sure that no tools, loose parts or rags are left in or on the machine

12 15. All regulating and safety devices shall be maintained with due care to ensure that they function properly. They may not be put out of action. 16. Before clearing the machine for use after maintenance or overhaul, check that operating pressures, temperatures and time settings are correct. Check that all control and shut-down devices are fitted and that they function correctly. If removed, check that the coupling guard of the compressor drive shaft has been reinstalled. 17. Every time the separator element is renewed, examine the discharge pipe and the inside of the oil separator vessel for carbon deposits; if excessive, the deposits should be removed. 18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering them, e.g. when steam cleaning. 19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork and in the air inlet and outlet systems of the compressor, is in good condition. If damaged, replace it by genuine material from the manufacturer to prevent the sound pressure level from increasing. 20. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls. 21. The following safety precautions are stressed when handling refrigerant: Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if required, use breathing protection. Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with water. If liquid refrigerant contacts the skin through clothing, never tear off or remove the latter; flush abundantly with fresh water over the clothing until all refrigerant is flushed away; then seek medical first aid. Also consult following safety precautions: Safety precautions during installation and Safety precautions during operation. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. Some precautions are general and cover several machine types and equipment; hence some statements may not apply to your machine

13 2 General description 2.1 Introduction General view Description These units are single-stage, oil-injected screw compressors, driven by an electric motor and enclosed in sound-insulated bodywork. Compressors with variable speed drive optimize energy consumption and reduce the operating pressure band by continuously matching the speed of the drive motor to the air net pressure. The following features are available as an option: Foodgrade Foodgrade oil is a unique high quality synthetic lubricant, specially created for oil-injected screw compressors that provide air for the food industry. Rotair Xtra oil RXD oil is a special, long-life lubricant for oil-injected screw compressors. It provides better cooling and extends the oil change interval. Water separator drain The water separator drain prevents water from entering in the compressed air net

14 Oil preheater (only for 400 V-50 Hz) This oil preheating system is installed in the oil tank in order to preheat the lubricant at low temperatures. High efficiency air filtration The high efficiency air filtration improves the quality of the air at the intake. This option is particularly useful in very dusty surroundings. Pre-filtration panel The pre-filtration panel protects the compressor's internal from dust and helps to avoid clogging of the air coolers (cooling air side). High pre-filtration panel The pre-filtration panel protects the compressor's internal from dust and helps to avoid clogging of the air coolers (cooling air side). This option is particularly useful in very dusty surroundings. Modulating control The modulating control system is designed to maintain a narrow net pressure band by throttling the air inlet, thus reducing the air flow (50% - 100%). Electronic drain (only for 400 V-50 Hz) The electronic water drain assures proper draining of condensate and prevents water from entering the compressed air net. For any malfunction of the draining process, the electronic water drain generates a warning message on the display of the electronic regulator. Energy recovery The compressor is provided with an energy recovery system to recover the major part of the compression heat in the form of hot water without any influence on the compressor performance. Phase Sequence Relay The phase sequence relay prevents the drive motor from rotating in the wrong direction. Automatic restart after voltage failure For compressors leaving the factory, this function is made inactive. If desired, the function can be activated. Consult your Customer Centre. If activated and provided the regulator was in the automatic operation mode and the compressor control mode (local, remote 1 or remote 2) was not changed during the voltage failure, the compressor will automatically restart if the supply voltage to the module is restored within a programmed time period (this time period is called the power recovery time). The power recovery time can be set between 1 and 254 seconds or to 0. If the power recovery time is set to 0, the compressor will always restart after a voltage failure, no matter how long it takes to restore the voltage

19 Air flow Air-cooled compressor Air drawn through filter and unloader (UA) is compressed in compressor element (E). Compressed air and oil are discharged through check valve (CV) to air receiver/oil separator (AR) where oil is separated from the compressed air. The air is blown through minimum pressure valve (Vp) to air cooler (Ca). The cooled air is discharged through the outlet towards the air net. An optional condensate trap may be provided between the air cooler and outlet valve. Check valve (CV) prevents blow-back of compressed air. Minimum pressure valve (Vp) prevents the receiver pressure from dropping below a minimum pressure. Oil system Air pressure forces the oil from receiver (AR) through oil cooler (Co), filters (OF), oil stop valve (Vs) and an oil injection valve to the compressor element (E) and the lubrication points. On air-cooled compressors, an oil injection valve will open at higher ambient temperatures to keep the element outlet temperature low. For air-cooled units, the oil temperature is controlled by regulating the speed of the fans (FN), to avoid overcooling and consequently condensation in the air receiver (AR). On air-cooled compressors with energy recovery or on water-cooled compressors, the oil temperature is controlled by a thermostatic valve to avoid overcooling and consequently condensation in the air receiver (AR). In the air receiver (AR) most of the oil is removed from the air centrifugally. Almost all of the remaining oil is removed by the separator element

20 2.3 Cooling and condensate system Condensate drain system Position of condensate drain (1) Automatic condensate drain As an option, a condensate trap can be installed downstream of the air cooler to prevent condensate from entering the air outlet pipe. The trap is provided with a float valve for automatically draining condensate and with a manual drain valve. Cooling system On air-cooled compressors, the air and oil coolers are cooled by fans. Water-cooled compressors are provided with a cooling water system, including combined oil and air coolers

21 2.4 Regulating system Flow diagrams Flow diagram Reference A B Designation To air cooler To/from oil cooler

22 Regulating system The compressor is controlled by electronic regulator (1). The regulator keeps the net pressure within programmable pressure limits by automatically loading and unloading the compressor depending on the air consumption. It also protects the compressor and monitors components subject to service. Unloading If the air consumption is less than the air delivery of the compressor, the net pressure increases. When the net pressure reaches the upper limit of the working pressure (unloading pressure), solenoid valve (5) is deenergized by the electronic regulator (1). The plunger of solenoid valve (5) moves downwards by spring force: Phase Description 1 The plunger of solenoid valve (5) shuts off the supply of receiver pressure towards chamber (2). 2 Control pressure present in chamber (2) is vented to atmosphere. Plunger (3) of blow-off valve (4) is moved by air receiver pressure allowing air receiver pressure to chamber (6). 3 Valve (7) is pushed upwards closing off the air inlet. 4 A small flow of air remains drawn in via channel (8), and is finally blown from receiver via channel (10) to the air inlet. 5 Air delivery is stopped (0%), the compressor runs unloaded while chamber (6) contains a steady overpressure (receiver unload pressure minus Blow Off valve (4) pressure drop). Loading When the net pressure decreases to the lower limit of the working pressure (loading pressure), solenoid valve (5) is energized. The plunger of solenoid valve (5) moves upwards against spring force: Phase 1 The plunger of solenoid valve (5) opens the supply of receiver pressure towards chamber (2). Plunger (3) of blow-off valve (4) moves, closing off the air pressure supply towards chamber (6). 2 Valve (7) moves downwards since the pressure in chamber (6) drops below atmospheric pressure, opening the air inlet to the compressor element. 3 Air delivery is resumed (100%), the compressor runs loaded while the piston-rod-valve assembly is only surrounded by atmospheric pressure. 2.5 Energy recovery system General description The maximum allowed pressure at the water side of the heat exchanger is 10 bar (145 psi). When the energy recovery system is not used, make sure that all water is out of the energy recovery system. The energy required in any compression process is mainly transformed into heat. The major part of the compression heat is dissipated through the oil system. The energy recovery systems are designed to recover

23 most of the above-mentioned heat as warm or hot water without any adverse influence on the compressor performance. After the compression stage, the oil is separated from the compressed air. The compressed air flows to the aftercooler and the oil flows to the oil cooler. The energy in the oil can be recovered by installing a heat exchanger in front of the oil cooler. The energy recovery systems can be applied as low temperature rise / high water flow systems (e.g. central heating in closed water circuits) or as high temperature rise / low water flow systems (e.g. pre-heating of boiler feed water in open water circuits). Main components The system mainly comprises: Oil/water heat exchanger Energy recovery valve Oil by-pass valve The necessary pipes, brackets, bolts, etc. Installation The compressor frame is prepared for the Energy recovery system. The connections must be 1". The use of a filter on the water intake is recommended to protect the cooling agents and the valves. A manual valve for isolation and water flow control will be installed on the water outlet in order to optimize the flow. The required qualities are given as a general rule in order to avoid problems caused by the cooling water. If in any doubt, contact your service representative. For the following specifications, dependent on the compressor type, contact your service representative: Minimum water inlet temperature Maximum water inlet temperature Required cooling water flow Maximum water pressure Recoverable energy Energy recovery system The recovery water enters the unit at the heat exchanger inlet connection. In the heat exchanger the compression heat is transferred from the compressor to the water. The water leaves the heat exchanger via the outlet connection. The oil flow of the compressor is controlled by a by-pass valve to ensure a reliable compressor operation and an optimum recovery of energy. Formula for recovered energy is : ==> Q = m x c x dt ==> m = Q / (c x dt) Q = the recovered energy in w m = the mass flow in kg/s c = the specific heat capacity in J/kgK (4.2 J/kgK for water) dt = the specific temperature change (inlet versus outlet) in K

24 Additional safety precautions The parts must only be lifted using suitable equipment in accordance with the applicable safety regulations. Loose or pivoting parts must be securely fastened before lifting. Wear a safety helmet when working in the area of overhead or lifting equipment. Protect hands to avoid injury from hot machine parts, e.g. during draining of oil. Protection caps, bags, etc. must be removed before connecting the pipes. Water hoses must be of correct size and suitable for the working pressure. The water connections must be free of strain. Pipe work or other parts with a temperature in excess of 80 C (176 F) must be guarded or insulated. Other high-temperature pipe work must be clearly marked. The water system installed outside the machine has to be protected by a safety device with set pressure according to the maximum cooling water inlet pressure. All maintenance work shall only be undertaken when the machine has cooled down. Never weld or perform any operation involving heat near the oil system

25 3 Electronic regulator 3.1 Electronic controller Control panel The display and the luminous indicator of AIRLOGIC allows: Viewing the operational status of the compressor at a given instant Viewing the maintenance messages (alarms, faults) Viewing the setting parameters of the compressor Description The AIRLOGIC is an electronic control plate equipped with a microprocessor used for the surveillance, management and monitoring of the compressor range of compressors at fixed speed and compressors with variable speed, as well as the compressors with integrated dryer. The AIRLOGIC offers several functions including the management of control, management of alarms and faults, information on the operational status of the unit, the configuration of remote control and the multicontroller management (optional). The AIRLOGIC allows in particular: The management of multiple analog inputs: An oil temperature sensor An internal pressure sensor A unit output pressure sensor The control and the management of fixed speed or variable speed compressor. The programming of operating time of loading and shutdown with possible selection of two control bands. The control, the fault reporting and the display of the operational status of the compressor by remote control. The automatic restarting in cascade after a mini-outage in power supply. The management of the integrated dryer module

26 In option, the centralized management of up to 4 compressors equipped with an AIRLOGIC. The exceptional modularity of the AIRLOGIC allows connecting additional electronic modules to add logical and/or analog inputs/outputs necessary for certain special applications (the modules available are described in section External communication). For example, the pressure loss of the air treatment chain can be managed from the AIRLOGIC. Indication of maintenance operations When a maintenance operation becomes necessary, either because the machine has reached the number of hours necessary before an intervention or because a sensor has detected a limit, a red indicator flashes and a message is displayed indicating the nature of the operation. The machine does not stop. Management of warnings The warning characterizes either a maintenance operation or a warning limit before reaching the limit of the fault, which when reached, would stop the machine. This allows anticipating a malfunctioning and dealing with it without compromising your production of compressed air. The indication of the nature of warning is transmitted to the AIRLOGIC. Management of functional faults On the appearance of a functional fault, the AIRLOGIC stops the compressor, indicates the fault by a red fault indicator and displays the message allowing rapid identification of the cause of the incident. An entry is added to the menu Historyof faults, displaying the nature of the fault, the date and the time as well as the value of certain parameters recorded when the fault appeared. Programming of pressure timers The real time clock of the AIRLOGIC allows, after programming the pressure timers, automatic starting and stopping of the compressor. While programming the loaded running, two pressure limits are available allowing to vary the control pressure over a time, depending on the applications

27 3.2 Control panel Regulator Display The screen displays all the information necessary for the navigation, the control of functional parameters and the error messages. The choice of 3 languages among 25 (configurable by the software) simplifies the understanding of the messages and the parameters

28 Luminous indicators Power supply indicator (green lamp lit): controller powered on. Automatic operation mode: green lamp on (the compressor was not stopped manually, it was either loaded or unloaded or stopped but ready to start automatically, if necessary). Error: red flashing light Warning: fixed red light Keys Start button, to start the compressor in automatic mode (the compressor will stop and restart automatically depending on the pressure variations in the network). Stop button, to stop the compressor when it is in automatic operation mode. The complete shutdown takes place only after a depressurization cycle of a modifiable period of 30 seconds

29 Cancel button: to cancel a modification of the value of a parameter. to return to a previous level in the menus. Shortcut to the menu Control Mode. Validate button: to enter the menu currently displayed while navigating the menu (the screen then displays the list of parameters of this menu) to validate the modification of the value of a parameter to enter the mode of modification of the value of a parameter. The value starts flashing. to rearm after a fault or a warning when the cause has been eliminated. Navigation Up to display the previous menu or parameter to increment the value of a parameter during its modification. Navigation Down to display the next menu or parameter to decrement the value of a parameter during its modification. 3.3 Changing the display language Procedure The display language can be configured according to the following operating procedure, described starting from one of the status screens: Press the Validate key for accessing the list of menus. Using the vertical navigation buttons, select Conf. User. from the menu. Press the Validate key for accessing the list of menu parameters. Using the vertical navigation buttons, select Language in use from the parameters menu. Activate the language parameter by pressing the Validate key. The language currently used is displayed. Press the Validate key again for activating the modification mode. The parameter flashes. A list with three languages is shown. Scroll to the desired language using the Navigation buttons. Validate your choice by pressing the Validate key. The parameter stops flashing

30 Use the Cancel button to return to the operational screen. 3.4 Regulation Command of the regulation In the case of ON/OFF regulation, the AIRLOGIC manages: The command of unloading when the pressure measured by the analog sensor reaches the idling pressure. The command of loading when the pressure measured by the analog sensor reaches the minimum regulation pressure (loading pressure). The command of motor shutdown after a period of idling. The restriction on restarting the motor if the pressure in the oil tank is higher than 1.5 bar (21.7 psi) or if the oil temperature at the outlet of the compression block is less than 2 C (35.6 F). If it is necessary to intervene on the machine when it is stopped, it should be placed in total safety by cutting off the electrical power supply. Stop on fault The following inputs and parameters will stop the compressor on fault when their status switches (for inputs) or when their value crosses the predefined values (top or bottom limits for the analog parameters or inputs): Input : Emergency stop Input : Motor overload Input : Turbine motor overload Input : Phase controller (option) Input : External fault (dryer, filter, other equipment ) Analog Input: temperature in outlet of compression block. In addition to the value of this temperature, its increase is also monitored during about 15 seconds after the starting of the compressor. If the temperature does not increase sufficiently, the controller considers that the motor is running in the wrong direction (the air is not compressed therefore the air is not heated) and stops the compressor. It is then necessary to cut off the power supply to the compressor, interchange the two phases of the supply to the main motor, then restart the power. This error cannot be cancelled by manipulations of the controller! Analog input: dryer temperature (estimate of the dew point set as a dryer "LAT parameter") too high or too low. There will be a warning if the temperature moves out of these high and low limits. Analog input internal pressure: this input replaces the high and low pressure switches of older regulation systems. If the internal pressure of the tank is too high, the controller displays a first warning notifying the user that the pressure is approaching dangerously close to the maximum limit. Then an error will be triggered (and shutdown the compressor) if the pressure continues increasing. Parameter differential pressure: a calculation of the difference of pressure between the machine outlet and the internal tank also replaces the differential pressure switches. Analog Input : motor temperature (sensors in option on certain machines) Warning before stop on fault Most of the values measured or calculated have before fault warning thresholds whose values are slightly below (or above) the maximum (or minimum) fault thresholds. The operator is warned that the operation of the compressor is approaching an error threshold. Control mode The AIRLOGIC has three control modes, Local/Remote/LAN

31 In Local mode, it is possible to start or stop the compressor directly from the controller. In Remote mode, the stop and start control is via a dry external contact (adjustment may still be internal (via the machine's sensor) or external (pressure switch.)) In LAN mode, start and stop control is by using the CANBUS compressor network through a master supervisor. For the latter two cases, the compressor is stopped by the local controller (maintenance..). The control mode must be first changed and returned to local mode. A shortcut using the Cancel key is provided for this. 3.5 Structure of menus Description The screens displayed on the controller are organized into menus, submenus, display screens and/or modification of parameter screens. The following section describes the general structure of the menus. However, depending on the options of the compressor, additional screens and/or parameters may be displayed. The logic of navigation and modification of parameters remains identical

32 General structure The structure of the AIRLOGIC is composed of two sections. The left hand column represents the status menus transmitting the parameters relating to the functional status of the machine; these are usable as check lists. The rest of the structure offers the parameters for configuring the compressor. Some of these parameters are read only while others can be modified, with restriction of access through password, depending on the qualification of the operator

33 Menu structure for fixed speed compressors

34 Menu structure for variable speed compressors

35 Reading the structure A vertical arrow pointing to a screen indicates that this screen is reached from the screen located above (the origin of the arrow) by pressing the navigation down key. A horizontal arrow indicates that it is possible to: go to the menu located at the top of the arrow by pressing the validate key. go to the screen for modifying the parameter displayed by pressing the validate key. return to the screen located at the end of the arrow pointing to the screen by pressing the cancel key. A vertical arrow leaving from a screen indicates that the screen can be reached from the one located below (at the tip of the arrow) by pressing on the navigation down key. 3.6 Modifying a parameter Description Use the vertical navigation buttons to select a menu item.

60 Fixed speed compressors

61 Variable speed compressors This menu displays logical and analog inputs for which one or more protections can be defined. Some inputs may appear several times if they have several protections. For example, the input T element outlet corresponding to the temperature sensor at the outlet of the compression element has a first protection for stopping the compressor if this temperature exceeds a certain value and a second protection preventing the compressor from starting if this temperature is too low. A detailed description of the protections of each of these inputs is provided on the following pages. Receiver pressure Protections of the input: internal pressure receiver. The pressure sensor is installed with a pressure tap in the oil tank, before the Air-oil separator

Corresponding to the pressure (7.5 bar (108 psi)) at which a pre-alarm will be displayed for informing the user that a protection limit is being approached. The pressure must cross the maxi threshold plus 5 seconds (value of this parameter) when an error will be generated. This parameter defines the maxi value that can be set for the parameter shd.maxi. Signifies that the compressor cannot start as long as the tank pressure is higher than this value (1.5 bar (21.7 psi)) This parameter defines the maximum value that can be set for the parameter P start.maxi. > value of next parameter Limit P maxi of this parameter 0 bar (0 psi) < value of the above parameter 0 s 10 s 0 bar (0 psi) 17 bar (246.5 psi) 0 bar (0 psi) 2.5 bar (36 psi) 0 bar (0 psi) 17 bar (246.5 psi) Element outlet Protects the input Temperature at element outlet. Analog input corresponding to the temperature sensor installed at the outlet of the compression element, taking AIR-OIL temperature at the highest point

Corresponding to the temperature (105 C (221 F)) at which a pre-alarm will be displayed to inform the operator that a protection limit is being approached. Time after the starting of the compressor when this protection becomes active. An error shall be generated if the temperature crosses the maximum threshold (110 C (230 F)) plus 3 seconds (value of this parameter). Protection against the wrong direction of rotation, no parameter is modifiable but the protection is active. > value of fixed parameter 120 C (248 F) 0 C (32 F) < value of the above parameter 0 s 120 s 0 s 10 s Delta P Protections on the calculated analog input Delta P.

64 Structure Definition Minimum Maximum Maximum value of the differential pressure beyond which an error is triggered. Maximum value of the differential pressure beyond which a warning appears in the menu Status 0.1 Delay after starting during which this protection is inactive. The differential pressure must exceed the maximum thresholds during more than 3 s for an error to be generated. Maximum value of the differential pressure beyond which a warning is displayed. Delay after starting during which this protection is inactive.

An error shall therefore be generated if this value is crossed for more than 3 s. The second protection at 1.3 bar (19 psi) allows warning the operator that the de-oiler filter is saturated and has to be replaced. Only a warning shall be displayed if the value of the differential pressure crosses this threshold for more than 5 minutes. Emergency Stop The protections on the input Emergency Stop.

66 The modification of this parameter is justified only if a change is made in the transmission ratio. No other reason can justify increasing the value of this parameter. Structure Definition Minimum Maximum This menu has only one parameter that allows limiting the maxi pressure serving as the limit of all the user pressure settings (loading, unloading pressure). 7.5 bar (108 psi) 17 bar (246.5 psi) Motor Rotations (only for fixed speed compressors) The parameters of this menu allow defining the protection against the wrong direction of motor rotation. This protection intervenes only after turning on the power to the AIRLOGIC controller. At the time of first loading of the compressor, after turning on the power, the controller measures the temperature increase at the outlet of the compression block during a certain time. If during this time interval Temp Duration, the temperature has not increased more than the value of the parameter Diffr.Temp., it is considered that the compressor is running in the wrong direction. For deactivating this error message, it is necessary to switch off the power to the compressor, interchange two of the three power supply phases to the motor and switch on the power again. Setting these two parameters to zero deactivates this protection.

74 Fixed speed compressors Variable speed compressors The first submenu Test screen allows testing the display as well as the LEDs of the controller (they are all lit as long as the key C is not pressed). The second submenu Outputs allows testing the correct activation of the outputs of the controller one by one. The compressor has to be stopped before these tests can be performed

75 3.20 Version menu Description Displays the version number of the application uploaded in the controller Information distributor menu Description Displays information that can be customized using the FSP software Password menu Description This menu is used to enter a password, needed to modify the parameters (only used by the distributor). This password is used to modify the parameters in the Conf distr menu. In case no key is activated during a period of 2 minutes, the password is no longer valid MCC menu Description The Multilogic (noted M.C.C.) is a function that can be activated in the presence of an electronic key allowing the connection of four compressors equipped with an AIRLOGIC. The operating principle is based on a control managed by a master compressor commanding the regulation of other machines of the network. The Multilogic allows maximum one variable speed compressor in the network

76 The Multilogic is a simple device for optimizing the operation of a multiple compressor installation. Control within one same pressure band eliminating the mode of control by pressure cascade. The energy consumptions are reduced and the pressure delivered is more stable. Balances the operating hours in order to facilitate the after-sales management of the production of air. Programs the timings of pressures for defining two pressure bands depending on the applications during the week. Simultaneous starting of compressors, programmable, for an immediate output of air, in order to rapidly inflate an unloaded network during an extended shutdown period. Instant programmable shutdown of all the compressors in the network to stop the production of air instantly at the end of the day. Starting in cascade to eliminate the intensity peak. This menu is described in a separate document delivered with the option External connection Fault report The output K09 is an inverter contact free of potential that allows to make a general fault report. The output is activated when an error occurs. Remote start-stop The input DI02 allows remote controlling, the start and stop of the compressor through an external contact. For this input to be operational, the parameter Control Mode of the menu Conf Distr must have the value Remote control. Connection to a Leadair The compatibility of a network of several compressors with control by a Leadair is provided through a Com- Box module for CAN <-> Serial protocol conversion External communication (optional) Box electronic modules Electronic modules are boxes connected to the AIRLOGIC that can manage signals from supplementary optional sensors installed either in the compressor fairing or close-by. From the AIRLOGIC, only the thresholds of faults parametered using the software (only for use by factory technicians) will be visible and will make it possible to centralize management of compressed air production. A few examples of applications: Controlling the pressure loss on the air treatment network indicating the acceptable limits of pressure loss. Measurement of ventilation air temperature Delta for indicating a radiator clogging. Measurement of the humidity of the compressed air for controlling the quality of air produced. All other applications that can use measurements from a sensor 4-20 ma. Sensors must be controlled separately from the electronic module Box. A parameter modification software (only to be used by qualified personnel) is necessary to configure warning thresholds and sensor errors or logic inputs connected to the electronic module

Working with machinery controlled by a frequency converter requires special safety precautions, which depend on the type of network (TN, TT or IT). Consult the manufacturer. The compressors comply with class A limits for radiated emissions according to EN A (2007). Beware of possible electromagnetic interference if stricter limits are valid. The compressors comply with limits in accordance with the EN :2004, EN :2009, EN :2006, EN :2004 and EN :2009 standards regarding the immunity of the equipment

98 Safety precautions for the frequency converter This equipment is used in high-voltage installations. During operation, this equipment contains rotating and live, bare parts. For this reason, it could cause severe injury or significant material damage if the required covers are removed or have not been properly maintained. When the machines are used in non-industrial areas, the installation location must be protected against unauthorized access (protective fencing, appropriate signs). All connection procedures must be carried out with the cabinet de-energized. All the work on the units must be carried out by trained personnel only. Death, serious injury, or substantial material damage can result if these warnings are not taken into account. Work on an open device must be carried out with extreme caution because external supply voltages may be present. The power and control terminals may be live even when the motor is not running. Dangerously high voltage levels are still present in the cabinet up to five minutes after it has been disconnected due to the DC link capacitors. For this reason, the cabinet should not be opened until after a reasonable period of time has elapsed. The operator is responsible for ensuring that the Power Module and other components are installed and connected in accordance with the recognized technical rules in the country of installation and applicable regional guidelines. Special attention should be paid to cable dimensioning, fuses, grounding, shutdown, disconnection, and overcurrent protection. If an item of protecting gear trips in a branch circuit, a leakage current may have been disconnected. To reduce the risk of fire or an electric shock, the current-carrying parts and other components in the cabinet unit should be inspected and damaged parts replaced. When an item of protective gear trips, the cause of tripping must be identified and rectified. The storage period should not exceed two years. If the device is stored for more than two years, the DC link capacitors of the devices must be reformed during commissioning. Consult your Service Centre for the reforming procedure

All electrical screens in the control cubicle and drive cubicle should be installed before start-up and shouldn't be removed during operation. Drawing reference Description 1 Install the compressor on a level floor suitable for taking its weight. For ventilation alternatives 1 and 2 (indicated as Alt. 1 and Alt. 2), the minimum distance between the compressor unit roof and the compressor room ceiling is 1200 mm (47.2 in). 2 Compressed air outlet valve (not in scope of supply) 3 Air delivery pipe: The pressure drop over the air outlet pipe can be calculated as follows: For SI Units: dp = (L x 450 x Qc 1.85 ) / (d 5 x p) dp = Pressure drop (recommended maximum = 0.1 bar) L = Length of outlet pipe in m Qc = Free air delivery of the compressor in l/s d = Inner diameter of the outlet pipe in mm p = Absolute pressure at the compressor outlet in bar(a) For British/American Units: dp = (L x Qc 1.85 ) / (1470 x d 5 x p) dp = Pressure drop (recommended maximum = 1.45 psi) L = Length of outlet pipe in ft Qc = Free air delivery of the compressor in cfm d = Inner diameter of the outlet pipe in in p = Absolute pressure at the compressor outlet in psig

102 Drawing reference Description 4 The inlet grids and ventilation fan should be installed in such a way that any recirculation of cooling air to the compressor inlet grid is avoided. The maximum air velocity through the grids is 5 m/s (16.5 ft/s). If cooling air ducts are installed, the maximum allowable pressure drop over the ducts is 30 Pa (0.12 in wc). The air temperature at the compressor inlet grid should be between 0 C and 46 C (32 F and F). The required ventilation to limit the compressor room temperature can be calculated as follows: For SI Units: On air-cooled compressors: Qv = 0.92 N/dT Qv = Required ventilation capacity in m 3 /s N = Shaft input of compressor in kw (for Pack compressors) N = Shaft input of compressor in kw + heat dissipated by dryer in kw (for Full-Feature compressors) dt = Temperature increase in compressor room For British/American Units: On air-cooled compressors: Qv = N/dT Qv = Required ventilation capacity in cfm N = Shaft input of compressor in hp (for Pack compressors) N = Shaft input of compressor in hp + heat dissipated by dryer in hp (for Full-Feature compressors) dt = Temperature increase in compressor room 5 Drain pipes to condensate collector. The drain pipes should be connected to an open circuit. 6 Control cubicle with monitoring panel 7 Main cable entry - A water shut-off valve and water drain valve in the energy recovery water inlet pipe and outlet pipe can be installed by the customer. If water shut-off valves are installed, a safety device with set pressure according to the maximum water inlet pressure has to be installed between the energy recovery water outlet pipe and the shut-off valve. Notes For more information concerning air nets, cooling systems, etc. check the compressor installation manual. All pipes should be connected stress free to the compressor unit. For dimensions and air flow directions check the dimension drawings

111 5 Operating instructions 5.1 Initial start-up Warning The operator must apply all relevant Safety precautions. Switch off the voltage before making any adjustment. Outdoor/altitude operation If the compressor is installed outdoors or if the air inlet temperature can be below freezing point, precautions must be taken. In this case, and also if operating at high altitude, consult your service representative. Moving/lifting The compressor can be moved by a lift truck using the slots in the frame. Make sure that the forks protrude from the other side of the frame. The compressor can also be lifted after inserting beams in the slots. Make sure that the beams cannot slide and that they protrude from the frame equally. The chains must be held parallel to the bodywork by chain spreaders in order not to damage the compressor. The lifting equipment must be placed in such a way that the compressor is lifted perpendicularly. Lift gently and avoid twisting. General preparations Step Action 1 Install the compressor, see the sections Dimension drawing, Installation proposal and Electric cable size. 2 Stick labels near the control panel to warn the operator that: the compressor may start automatically after a voltage failure the compressor is automatically started and stopped the compressor may be remotely controlled 3 A number of VCI (Volatile Corrosion Inhibitor) plates are provided inside the bodywork to protect the compressor against corrosion. Remove the plates. 4 If the compressor has not run for the past 6 months, it is required to improve the lubrication of the compressor element before starting. Fill up the compressor element as described in section Oil change (paragraph: Filling the compressor element with oil). 5 Check that the compressor is filled with oil; the pointer of the oil level indicator should be in the green range (see the section Oil change)

112 Protection during transport Transport fixtures Step Action 1 The gear casing supports and motor support are secured to the frame, immobilizing the vibration dampers during transport. 2 Remove the bushes (1) from the gear casing supports and the motor support. Electric cabinet Environmental condition for the electrical equipment: 3K3 according to IEC Step Action 1 Check that the electrical connections correspond to the local codes. The installation must be earthed and protected by fuses in all phases. An isolating switch must be fitted. 2 Check the wires on transformers for correct connection. 3 Check the setting of the circuit breakers (see the section Settings of circuit breakers). 4 Check that overload relay (F21) is set for automatic resetting and check its setting (see the section Setting of overload relay and fuses)

113 Start up Step Action 1 Close the drain valves (see the section Cooling and condensate system). 2 Switch on the voltage. 3 Start the compressor and stop it immediately. Check the rotation direction of the drive motor while the motor is coasting to a stop. To determine the rotation direction of the motor, look at the fan through the grating at the non-drive end of the motor. The correct rotation direction is indicated by an arrow on the gear casing and on the fan cowl.
