DEAR ENGINEERS
WE HAVE 910KVA GENERATOR WHICH CAN NOT BE START UNTILL IT ENDS THE COOLING TIME,EVENIF UTILITY POWER INTERRUPTED.SO WHAT CAN YOU ADVISE ME TO CORRECT THIS PROBLEM?
Dearest,
For Diesel Engine drive Electric Generators:
Check your DC control Panel on the shutdown cooling Timer or its slave relay, probably it is deffective
Check also the bypass relay if deffective for the auto-start mode- selector Switched to 'Mains Fail'.
If thiis wont work out for you…
Check the whole electrical path circuitry for auto-start and auto-shutdn device, relays, switches and pilot wires etc.,
For Catterpillar Gas turbine drive Electric Generators:
Same procedure as the above…
Rare case, instead check proper functioning of its mecury switches
GOOD LUCK!
