for 4 speed-controlled compressors
For each regulated compressor, a control range for switching standard compressors on or off can be programmed. The mains pressure is used as a pressure setpoint, connected via an isolation amplifier from the analog output of the connection module to the pressure transmitter input of the compressor. A changeover relay (R1) switches back to the internal pressure sensor if the bus connection is faulty or the voltage at the master controller or connection module drops.
