All MOTORSCOPE and LEVEL CONTROLLER units have RS232 outputs for serial communication. The COMMUNICATOR connects to this serial port by means of a RS232 cable (standard with unit). During operation, the control units transmit information to the COMMUNICATOR, which it interprets to control 3 relays.
L.E.D. lights display the state of the relays. The COMMUNICATOR also has a 4-20mA output which indicates the present running power / level relative to the LOW and HIGH limits. For detailed error information or to adjust the settings on the MOTORSCOPE Unit, an OPTIMIZER can be plugged in on the OPTIMIZER plug.
