ahmedaytona asked Diesel 3 phase 100 Kva electric generator shuts down?

I have a Diesel generator using leroy sommers alternator and which uses intelilite MRS 11 controller , it is 380 V , 50 Hz , yesterday i started having problems , after running the genset for like 12 seconds it shuts down and i get two error msgs the first one is : Shutdown Level for Phase 1 under volts the second error msg is : Shutdown Level for Gen voltage Unbalance . in the first 12 seconds the voltage on 3 phases got no problem and after 12 seconds the generator auto shuts down and i cannot seem the find the problem , any help will be appreciated

And got the following answer:

Its seems ur AVR circuit circuits not functioning or mal functioning check all glass fuses & relays ( coil & contacts of pcb mounted miniature relays ) healthines in AVR PCB isn't open type or sealed type ?,. Check all input plugs & connection to speed sensor too.voltage monitoring relay should pick up (AVR pcb). go thro the manual if there any , what is the climate is ti too Humid chill & windy , Is ur Generator is fitted out side or inside building ? some time certain environment AVR circuit may mal function , some time there won't be a fault at all .once after checking all those points -try again best of Luck - or pm me
