Automation & Control Pvt. LtdGCU 101

GCU 101 is a1-Phase/3-Phase automatic/manual generator

controller module. It controls start and stop function of the

engine, monitors the generator operations in both automatic &

manual mode. It uses an advanced single chip microcomputer

for sophisticated automation for generator plant, it is designed

by taking great care related with electromagnetic interfaces for

trouble free operation in harsh electrical environment.

If the mains fails due to over or under voltage or loss of mains, GCU 101 initiates an automatic genset start cycle

following complete AMF function sequence including load transfer to the generator by switching the generator and

mains contactors. It is possible to select up to 5 start attempts with both crank and rest period adjustable. After engine

warm up period has expired the generator supply is connected . After main supply returns and it gets restore the load

will automatically transfer back to the mains and genset will stop after cooling down time. During all cycles, generator

is fully protected against all types of given fault conditions. All alarms occurring at abnormal genset conditions are

computed and displayed either by LED or by four-digit display and if necessary the genset is get stopped. The manual

mode is selected by means of push button switches. The generator start & stop functions are carried out by means of

push button switches & contactor change over is performed by internal logic automatically. Values of Voltage, Current

frequency to initiate genset start cycle and timer settings of preheat, cooling down time etc. are free programmable.

The GCU 101 has 43 powerful programmable parameters to fit the program "ow to customer needs.
