GCU - 102

Description :

GCU-102 is a single / three phase controller for the protection of genset. GCU 102 is a microprocessor based controller unit containing the necessary function for the protection & control of the genset. It provides protection against LLOP, HCT, and any two faults which can be specified by the user as per his requirement. The main feature is compact in size & reliability.
When Mains supply fails, the GCU 102 module automatically initiates the generator start sequence. The module will give set number of cranks to the generator. If the Generator starts within set number of cranks, the module will shift the load to the Generator by activating Generator contactor after Warm-up period. If the Generator do not start in set number of cranks START FAIL ( StrF ) fault will occur.
When the Mains supply comes back to the normal level, the load will shift to the Mains contactor after Mains Restore time & cool down time will be initiated. In cool down time, the Generator will run without load. Then the Generator is stopped in stop time. If the Mains fail during cool down time then load will immediately transferred to the Generator.
