Controller to "power over frequency shutdown" or "power under frequency shutdown".
Check whether genset power voltage is normal.
Check whether genset speed is normal.
Check whether "rated frequency" of controller setting is normal.
About generator block of electronic governor.
Adjust gain and differential of electronic governor(stability).
According to the actual situation to adjust "status adjustment" switch.
Check whether there is air in oil circuit of genset.
About "power overcurrent trip".
Check whether current transformer is too small.
Check controller "overload current" percentages are set too small.
Check whether controller "full load current value" is too small.
Check whether load power is greater than set power.
About current is not stable.
Check whether public end of current transformer is in a good grounding.
Check whether connection of wire diameter is suitable.
About current is not correct.
Check whether current transformer and unit power are matching.
Check the change of controller current transformer.
About multiple gen-gen reverse power.
Check whether the current transformer is reverse. (P1 to P2, namely the power flow to the load. S1 connects each phase input current of three phase, S2 connects public output.) .
Check whether public end of current transformer is grounded.
Check whether electronic speed control plate is adjustable.
Check whether electronic pressure regulator is adjustable.
Multiple gen-gen controllers can't achieve gen-gen.
Check whether gen-gen communication line is connected.
Check multiple gen-gen conditions: speed, voltage, phase sequence is synchronized.
Check whether multiple gen-gen module address is in conflict.
Center of AVR and GOV whether can choose the right and automatically adjust, whether the voltage and the speed can be automatically adjusted to gen-gen required value.
Genset generating voltage is abnormal(too high or too low).
Check rated voltage value of controller Settings.
Adjust the external electronic adjustable clamp rated voltage and its wiring.
After genset closing with load, the current display is not correct.
Check change of current transformer and wiring.
Genset speed and frequency conform to the rating speed and frequency.
Check and make sure the engine gear, and adjust to the corresponding number of teeth.
