CONTROL UNIT OPERATION
The ME200 E control unit, is part of the ME200 family, serves to monitor the
transformer/motor temperatures by means of 3-wire PT100 probes on up to 8
channels.It is equipped with 5 relays, 2 for ventilation, 1 for signalling faults and
2 for PRE-AL and ALARM signals. For connection with supervision systems
(PLC/SCADA) an ETHERNET port is available with MODBUS-TCP
communication protocol, with parameters that can be set via browser.
When one of the temperature probes exceeds the value set by the limits by 1
degree centigrade, the relays and corresponding LEDs switch after about 1
second.
