28 6.7 GROUNDING DNGER No Grounding! Risk of explosion and risk of electric shock. Electrostatic control units and the associated spray equipment may only be connected to mains supplies with a protective conductor connection (PE conductor)! WRNING Heavy paint mist if grounding is insufficient! Danger of poisoning. Insufficient paint application quality: Ground all device components. Ground the work pieces to be coated. For safety reasons, the control unit must be properly grounded. The grounding connection to the energy supply (socket) takes the form of the mains connection cable's protective conductor, while that to the work piece/system is via the knurled screw on the rear of the control unit. oth connections are absolutely essential. If installed correctly as described above, the spray gun is grounded via the gun cable between the control unit and spray gun. Good grounding of the work piece is also necessary for optimum powder coating. poorly grounded work piece causes: dangerous electric charging of the work piece, very poor wrap-around, uneven coating, back spraying to the spray gun, i.e., contamination. Prerequisites for perfect grounding and coating are: clean suspension of the work piece to be coated, grounding of spraying booth, conveyor system and suspension on the part of the building site in accordance with the operating manual or the manufacturer's information, grounding of all conductive parts within the working area. The grounding resistance of the work piece must not exceed 1 MΩ (megohm). (Resistance to ground measured at 500 V or 1000 V). The footwear worn by the operators must comply with the requirements of EN ISO The measured insulation resistance must not exceed 100 MΩ (megohms). 28

29 The protective clothing, including gloves, must comply with the requirements of EN ISO The measured insulation resistance must not exceed 100 MΩ (megohms). Sparks between conveyor, conveyor hooks (hangers) and work piece can occur if electric contact points between conveyor, conveyor hooks (hangers) and work piece are not sufficiently cleaned and therefore the work pieces are not sufficiently grounded! These sparks can cause heavy radio frequency interference (EMC). 29

For a change to the node ID to take effect, the control unit must be switched off and on again. 32

33 7 OPERTION 7.1 TRINING THE OPERTING STFF WRNING Incorrect operation! Risk of injury and damage to the device. The operating staff must be qualified to operate the entire system. efore work commences, the operating staff must receive appropriate system training. The operating staff must be familiar with the provisions of European standards DIN EN and DIN EN SFETY INSTRUCTIONS WRNING Incorrect operation! Risk of injury and damage to the device. If contact with powder products or cleaning agents causes skin irritation, appropriate precautionary measures must be taken, e.g., wearing protective clothing. The footwear worn by operating staff must comply with EN ISO The measured insulation resistance must not exceed 100 megohms. The protective clothing, including gloves, must comply with EN ISO The measured insulation resistance must not exceed 100 megohms. 33

34 WRNING Incorrect installation/operation! Risk of injury and damage to the device. When commissioning and for all work, read and follow the operating manual and safety regulations for the additionally required system components. 7.3 CONTROLLLE SPRY GUNS Two powder spray guns can be connected to the control unit. These two guns are controlled totally independently of one another. The automatic guns are activated and deactivated via the superordinate controller. The gun types which can be controlled are listed in Chapter GUN CLE LENGTHS Gun cables are available in the following standard lengths: 5 m; ft, 10 m; ft and 20 m; ft. Note: Maximum permitted gun cable length 35 m; ft. Keep the cable length as short as possible as the performance of the gun is reduced with each additional meter of cable. 34

35 7.5 CONTROL FUNCTIONS ON CONTROL UNIT The control unit does not have its own operating or display elements. ll specifications (set points) and displays (actual values) are transferred by electric signals from a master controller via the CN bus. The software in the master controller determines the input options for set points and displays of the current actual values SETTING THE HIGH VOLTGE The set point high voltage of both channels on the control unit can be set independently of each other and the actual calculated high voltage value can be shown on the central controller. Note: The specified high voltage value is only reached when idling and is reduced as soon as current flows. Voltage [kv] Current [μ] The high voltage can be predefined in 1 kv steps between 10 and 100 kv. The graphic shows the characteristic curves for three different high-voltage settings. You can see from the blue curve that a setting of 60 kv allows a maximum current of 110 μ. 35

36 7.5.2 SETTING OF CURRENT LIMITING The spray current limitation can be set and measured independently in both of the control unit's channels. If the measured spray current reaches or exceeds the set value, the high voltage is adjusted downwards until the set spray current is reduced to maximum. Current [μ] Voltage [kv] The current limitation can be predefined in 1 μ steps between 5 and 120 μ. The graphic shows the characteristic curves for three different current restrictions. You can see from the blue curve that the voltage reduces quickly with a low current restriction. 36

37 7.5.3 SETTINGS OF HIGH-VOLTGE CHRCTERISTIC Regardless of the high voltage and spray current limitation set, the characteristic curve of the voltage/current curve can be set on the control unit. Three levels are possible: 1. Standard level -> maximum performance 2. Medium level ->reduced performance 3. Soft level -> greatly reduced performance Properties of the characteristic curve Field of application/remarks Standard level for poorly rechargeable types of powder Open-circuit voltage 100 kv for high powder application Maximum current 120 μ (Current limiting) This setting corresponds to the usual WGNER high-voltage modules and control units. Medium level for small surfaces Open-circuit voltage 100 kv for types of powder that recharge well Maximum current 120 μ (Current limiting) To reduce the effects of overcoating such as craters and orange peel. Increasing the open-circuit voltage allows for a greater distance between the spray gun and the work piece while maintaining sufficient powder charging. for types of powder that recharge well Soft level Open-circuit voltage 100 kv for small powder application Maximum current 80 μ for post-coatings Current [μ] Voltage [kv] The characteristic slope can be set at three levels. The graphic shows the characteristic curves for the three different slopes. 37

38 The defined field of application should only be seen as a guideline and must be adjusted to the type of powder, the distance to the work piece and the work piece geometry. The combination of high-voltage setting, current limitation and characteristic slope results in a large number of settings options for each coating situation SETTING THE IR VOLUME The set point air volume in all 6 channels on the control unit can be set independently of each other and the actual air volume measured can be shown on the central controller. The air volume can be set in Nm³/h steps between 0.00 Nm³/h and 6.00 Nm³/h. Note that depending on the application, cases may arise where the maximum flow rate cannot be reached. In this case, the control unit will issue a warning and the maximum set point must be reduced. These maximum values can be found in the instructions for the various injectors and guns IR SUPPLY PRESSURE The control units are calibrated in the factory to a primary pressure of between MPa; 6-8 bar; psi. It is important that the atmospheric pressure supply line has a large cross-section and that the air supply pressure does not drop during high demand. 38

40 7.7 EMERGENCY OPERTION The has a simple emergency mode. The aim of the emergency mode is to permit minimal further work should the CN bus or superordinate controller fail. The emergency mode parameters must be set before the CN bus fails, otherwise emergency mode does not function CTIVTION OF EMERGENCY MODE In order to activate emergency mode, the DIP switch 4 must be set to "ON" (see figure below). The switch status is only read in when the device is switched on (powered up). So first set the switch and then restart the device Emergency mode deactivated Emergency mode activated P_ FUNCTIONING OF THE EMERGENCY MODE The coating system is activated and deactivated using the release hardware line. If the release is present, the coating system is activated. Unless the set points in the emergency mode parameter set are set to "0", both guns are always activated. When emergency mode is activated, the power LED flashes and the CN LED remains dark. In addition to emergency mode activation, an error reset is performed for every positive flank of the release signal. The device's CN transceiver is switched off. This means that the device cannot send or receive messages. 40
