Application
Object : Releases and pilots the whole start sequences of a high and medium power generating set. The sequences can be caused by : the local power supply stop, top EJP operation, test, ... This PLC can be plugged on a network (modbus dialogue), questioned by a supervisor via the comuted network.
Particularities :
. Admits important voltage drops at the generator's start,
. Measures the frequency of the voltage delivered by the generating set,
. IP 65 sealed front face,
. defaults statement,
. Programming through ALOGRAF software,
. Supervision with CITECT software.
