REGULATORS Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 121 Vacuum technology Catalogue TOP VIEWOF THE REGULATOR CONNECTOR Ordering codes Installation/ Operation PNEUMATIC CONNECTION The compressed air is connected by means of M5 threaded holes (for size 0 regulators), G 1/4” threaded holes (for size 1 regulators) and G 1/2” threaded holes (for size 3 regulators) on the body. Before making the connections, eliminate any impurities in the connecting pipes to prevent chippings or dust entering the unit. Do not supply the circuit with more than 10 bar pressure and make sure that the compressed air is dried (excessive condensate could cause the appliance to malfunction) and filtered at 5 micron. The minimum supply pressure required depends on the characteristics of the vacuum generator. If a silencer is applied to the discharge path the unit response time may change; periodically check that the silencer is not blocked and replace it if necessary. NOTES ON OPERATION If the electric supply is interrupted, the outlet pressure is maintained at the set value. However, maintaining the exact value cannot be ensured as it is impossible to operate the solenoid valves. In order to discharge the circuit downstream, zero the reference, make sure that the display shows a pressure value equal to zero and then disconnect the electric power supply. A version of the device is available that exhausts the downstream circuit when the power supply is removed. (Option “A” at the end of the ordering code). If the compressed-air supply is suspended and the electric power supply is maintained a whirring will be heard that is due to the solenoid valves; an operating parameter can be activated (P18) that triggers the regulator protection whenever the requested pressure is not reached within 4 seconds of the reference signal being sent. In this case the system will intervene to interrupt the control of the solenoid valves. Every twenty seconds, the unit will start the reset procedure until standard operating conditions have been restored. ELECTRICAL CONNECTION For the electrical connection a SUB-D 15-pole female is used. Wire in accordance with the wiring diagram shown below.
