GCU 101

Description :

GCU-101 is a 1-phase / 3-phase Automatic / Manual Generator controller module including protection for (STANDBY) GEN-SETS. It uses an advanced single chip microcomputer for an easy and trouble free GEN-SET control in case of mains power failures. If mains fail (over / under voltage, loss of mains voltage), GCU-101 initiates an automatic GEN-SET start cycle including load transfer to the generator by switching the generator contactors. After the mains is restored the load will be automatically transferred back to mains and the GEN-SET will stop after a cool down time. During all cycles, generator is fully protected against malfunction. All alarms occurring at abnormal GEN-SET conditions are computed and displayed either by LED or by the four-digit display and if necessary the GEN-SET gets stopped.
Values of over/under voltage, frequency and overload current (see parameter No.: 6,7,9,10,11) and timer settings for Preheat, cooling down time (see parameter No.: 5,14) etc. are programmable. The GCU-101 has 40 powerful programmable parameters to fit the program flow to customer needs.
