4 1 Introduction In applications where several compressors are used for an air pressure supply system, it is desirable to use a supervisory staging and sequencing control. This control has been realized for many years by the CONDOR GLW 16 and as of June 2004 by the GLW 4 (with many additional functions such as time switch, ball valve function, primary load/load changeover and much more). A staging and sequencing control regulates uniform distribution of the individual compressors hours and guarantees an optimal efficient and economical operation of several compressors. The individual compressor parameters can be programmed in up to 6 different profiles which, considering the general settings, are controlled by the internal time switch. 2 Safety guidelines This operating manual exclusively describes the control unit. It contains important references and warnings, and therefore should be read by the installer as well as by the relevant operator before installing and operating the unit. Note! Not only should the general safety references mentioned in this Safety guidelines section be observed, but also any special safety references referred to in the other sections of the manual. 2.1 Marking of guidelines in the operating manual Safety references contained in this operating manual, which can cause personal danger on failure to observe them, are marked with this general danger symbol. marked with this general danger warning symbol against electric voltage..

5 2.2 To be observed The description and instructions in this operating manual relate to the GLW 4 control. This operating manual does not take into account either all possible design details, styles or all possible coincidences and incidents, which may occur during mounting, operation and maintenance. The control is to be used by professionally trained personnel (see EN ). In such case that not all of the information and instructions are found in this operating manual, please ask the manufacturer, Condor-Werke (address see page 2). CONDOR-WERKE Gebr. Frede GmbH & Co. KG takes no responsibility in case the operating manual is disregarded. Connecting and maintenance of the control may be carried out by qualified personnel only. Before operation, the GLW 4 must be installed in a suitable enclosure. Before operating, make sure that: The complete installation is voltage free and secured against power up when mounting and servicing, The terminals of the GLW 4 have been properly connected, The technical condition of the connected compressors are adjusted to the special settings of the GLW 4, The connections have been carried out with diligence, The installation has been professionally secured. 2.3 Additional documents In addition to this operating manual and depending on the layout of the switchgear, further documents and manuals may be attached to this operating manual and they are to be observed, such as: Switching and connecting diagrams Programming examples 3 General If several compressors are to be used in a in a pressurized air system, it is convenient to assign the primary and peak-demand load operating mode to the compressors. Primary load is the operation of a compressor on low air demand. Should the demand for air rise such that one compressor cannot meet the demand alone, then a second compressor is staged in order to cover the peak-load demand. The GLW 4 is a staging and sequencing control for up to 4 compressors! All settings, e.g. load changeover time and thresholds are programmed by means of three keys next to the LCD display without any special programming knowledge. All specific compressor data are programmed in so called profiles. The internal time switch can control up to 6 different profiles. Connection to the pressurized air system is not yet required. Page 5

6 Further Advantages For each compressor, cut-in and cut-out thresholds can be programmed. In case only two compressors need to be controlled, then the other two remaining switching hysteresis can be used for additional monitoring purposes. Besides the staging and sequencing features, the following special functions are available: - Freely programmable integrated time switch. - Free assignment of primary load and load changeover (i.e. the primary compressor runs always, the other compressors are sequenced) - Freely programmable ball valve function, with max. three compressors. - Four separate inputs for power up time, operating hours, errors or switching cycles. - Following completion of a preset stand-by time the next compressor, if desired, will be activated, even if it has not yet reached its own activation threshold - The function "release input", e.g. switches the GLW 4 off for servicing purposes, after reaching the next cut-out threshold. - Programming protection: programming is only possible if the password is known! - All settings can be deactivated separately! - Freely programmable voltage free SPDT as alarm output. With the GLW 4, CONDOR-WERKE offers an electronic solution for staging and sequencing up to max. 4 compressors. The GLW 4 is laid out for 35mm DIN-rail mounting according to DIN EN The system can be used to control piston as well as screw compressors. A rotation of the compressor starting sequence ensures that all connected compressors are equally used. Rotation of the pressure threshold points associated with each compressor is automatically carried out by entering the "load changeover time". A load changeover time of 0 to 999,9 can be programmed. When entering "", the load changeover is not carried out. By entering "primary load", the connected compressor will not be considered during rotation. Rotation only then takes place after both the load changeover time and the highest cut-in pressure setting have been reached. The possibility is also given to program all compressors with identical cut-off pressures. However, setting the same cut-in pressures is not possible. 4 Hardware The GLW 4 is a compressor control unit featuring an integrated relative pressure transducer (0-16 bar, quick connect ) for DIN-rail mounting, 6 optocoupler inputs, 5 voltage free SPDT's, an analog input (two wire, ma) for external pressure measurement, a graphic LCD display, 3 key operation and a V24 interface. The following technical points should be observed: Page 6

7 4.1 Pressure measuring methods The GLW 4 can measure pressure using two methods: a.) Internal pressure transducer The control is connected directly with the air pressure system by means of a quick connect for a 6 mm pneumatic tube (e.g. FESTO Type PAN 6X1). Measuring range: 0 to 16 bar b.) External pressure transducer A standard pressure transducer (two wire, ma) can be connected to p+ and p- terminals of the controller. It must be activated in the main menu under general settings "Pressure measurement external". The internal pressure sensor can only be used for a max. measuring range of bar. When connecting an external pressure transducer, please observe the polarity. 4.2 Remote release input (I51) (GLW 4: I51; GLW 4-S and GLW 4-SK: X2-4) In operating mode, a voltage (230 V AC) must be applied to terminal I51. As soon as the voltage on I51 is switched off (e.g. night time switchboard power down) the GLW 4 is powered down after exceeding the cut-in threshold 1. When the voltage is again applied to I 51, the GLW 4 will continue to operate. When using this function, all set times are not deleted but continue to function after powering up. The corresponding reference potential (generally the N conductor) must be applied to terminals I52/I Compressor inputs (GLW 4: I11 bis I42; GLW 4-S and GLW 4-SK: X2-6 bis 9) The input terminals I11 up to I42 can be used to additionally monitor the connected compressors (operating hours or error messages or switching cycles). The input logic (NO or NC) of the inputs can changed in the menu "Logic inputs" under general settings. NO = An action follows when applying a voltage. NC = An action follows when removing a voltage. This function requires the corresponding compressor inputs be connected. 4.4 Alarm output (GLW 4: 51/52/54; GLW 4-S and GLW 4-SK: X2-1 bis 3) If the system pressure sinks below the set alarm pressure and if the set monitoring time has elapsed and if the alarm relay in the menu has been set to ON, then an alarm is given over the alarm output (voltage free SPDT). Furthermore, an alarm is given when the cut-out pressures are exceeded as soon as the monitoring time has elapsed and the alarm relay in the menu has been activated (On). 4.5 Time switch Very often in compressor applications, timer functions are required. The timer functions are activated when under general settings, operating profiles, "Time switch" has been set. This means that the selected profiles in the timer program are executed. Before this, however, date and time under general settings should be checked and eventually updated. An automatic summer/winter changeover is not available. Page 7

8 4.6 Bridging time switch (GLW 4: I 61 and I52/I62; GLW 4-S: X2-5 and X1-N) The time switch function is switched off as soon as e.g., a 230 V AC voltage is applied to terminal I61 and the reference potential (generally the N conductor) has been connected to terminals I52/I62 and under general settings, function external input, the profile selected at the time has been programmed. 4.7 Ball valve/output K4 Once the function ball valve/output K4 has been programmed to "On", then only three compressors can be controlled while the fourth connection is used as a ball valve control. This means, e.g. that the fourth voltage free SPDT can be used to control a weekend disconnection, hereby reducing energy costs caused by air leakage in the pressure line(s). 4.8 External pressure measurement (GLW 4: p+ / p-; GLW 4-S and GLW 4-SK: X2-10 and 11) When selecting "external" for pressure measurement under general settings, the internal pressure transducer is deactivated and the external pressure transducer (two wire, ma) is activated. Furthermore, the corresponding measuring range end value must also be entered. Any standard two wire pressure transducer, ma, U B 18-21V DC can be used. Please observe the polarity when connecting an external pressure transducer! 5 Programming Programming is carried out using the 3 keys. In order to change a parameter, a password must be entered! The default password of the GLW 4 control is Changing the password can be carried out under general setting and should only be done with the necessary corresponding care. Reactivating the control is only possible by CONDOR WERKE Gebr. Frede GmbH & Co. KG upon loss of the password. Once the operating voltage is applied, the Condor Logo (a short acoustic signal can be heard) with the type designation GLW 4 and software version are displayed. When pressing one of the keys, the main display appears: Page 8

Pressing the OK key will access the corresponding sub menu, use the arrow keys to scroll through the selected menu. 5.1 First steps In the general settings menu, all basic settings are carried out. In the first step, the "general settings" are entered: pressure measurement; unit; language; password; operating method profile, i.e. using the time switch or a specific profile; function of the external input; date, time; alarm settings; logic inputs of the compressors; ball valve function; direct load changeover or only upon reaching the cut-out threshold and the buzzer (on/off). Thereafter if required, the time switch settings in the menu "Time switch program" are carried out and the corresponding profiles specified. Finally, the respective profiles are programmed. Up to 6 different profiles can be programmed as long as the time switch is activated and the different profiles in the time switch program have been selected. 5.2 Front view Page 9

This, however, is only possible when the corresponding logic has been programmed. Pressing all three keys simultaneously, will delete the monitoring data. 5.5 General settings Basic settings are carried out in the general settings menu. All special sub-menu settings are explained below as follows: General settings: Operating mode profiles In this menu, the basic logic of the rules are programmed: The control is powered down. P1 up to P6 Only the selected profile is executed. Time switch The control executes the settings made in the time switch program General settings: External input In this menu, the basic logic of the rules are programmed: The control is powered down. P1 up to P6 Only the selected profile is executed. Time switch The control executes the settings made in the time switch program General settings: Alarm pressure, Alarm time, Alarm relay Under alarm pressure, the alarm level is set, how long the alarm should last and whether also the voltage free SPDT is active. An alarm is given as soon as the alarm time has elapsed and the set alarm level has still not been exceeded General settings: Logic inputs Here, the logic of the inputs for mains power up time, operating hours, errors and switching cycles can be programmed General settings: Buzzer When selecting "On", the internal alarm buzzer is activated General settings: Ball valve/output K4 When selecting "On", only three compressors can be controlled. With the fourth contact, an electric ball valve can be controlled (e.g. week end power down General settings: Immediate load changeover After the load change time has expired and upon reaching the next cut-out threshold, the chronological order of the compressors change. If "On" has been selected in the menu, the load changeover is carried out immediately without reaching the next cut-out threshold. Page 11

14 5.7 Selecting profiles In the menu "Select profile" the individual compressor data are entered in the selected profile. Up to 6 different profiles can be programmed. Under "Select profile" "Operating mode", 3 different settings are possible. Primary load (the compressor is not considered when rotating), Load changeover (the compressor is considered when rotating) and OFF (no compressors connected). Finally, the cut-in and cut-out pressures of the individual compressors are programmed. All special settings are described below in detail as follows: Standby-time (Waiting time) In case the relevant compressor has not reached the programmed cut-out threshold after the standby-time (0 to 999 minutes) has elapsed, the next compressor in line is automatically staged. When selecting "0", this function is deactivated Load changeover time The load changeover time determines the actual rotation time period between the connected compressors! The changeover time is the time in which compressor 1 is triggered, i.e. the load changeover does not take place after e.g. 24 hours have elapsed but only when the relevant compressor has been triggered for the length of the programmed time. After the load changeover time has elapsed, the primary load changes then to the next compressor. A load change over time of 0 to 999 hours can be programmed. If under General Settings "Load changeover switch immediately" has been set to On, the load changeover is carried out immediately. If has been selected, then the load changeover is carried out when reaching the highest cut-in threshold. Please note that the load changeover time is the time during which the compressor is triggered! Monitoring time The monitoring time is initiated once the applied system pressure sinks below the set alarm pressure or rises above the highest cut-out threshold. If after the monitoring time has elapsed and the system pressure is still below the set alarm level (or above the highest cut-out threshold), then the alarm output is activated. Page 14
