Start one of the Generator Sets 150 kW and perform Function Check; press
AC CIRCUIT INTERRUPTER ON pushbutton switch.
Start second Generator Set 150 kW and perform Function Check.
Compare output voltages and frequency values for the two Generator Sets
150 kW.
(max. frequency deviation < 0,2 Hz)
(max. voltage deviation < 2 V)
Press SYNCHRONIZATION ON pushbutton switch.
(Generator Sets 150 kW will be automatically synchronized.)
Synchronization of the two Generator Sets 150 kW is complete when AC
CIRCUIT INTERRUPTER ON lamp lights up.
AMPS and KILOWATT meter readings for the two Generator Sets 150 kW
must be almost identical.
(max. KILOWATT difference < 20 kW)
(max. AMPS difference
< 40 A)
If actual differences exceed the allowable range, press AC CIRCUIT I
NTERRUPTER OFF
pushbutton switch and recheck frequency and voltage settings (item 3) for the
Generator Sets
150 kW.
Power Distribution Unit (PDU)
After switching ON the EPP AC circuit, the PDU will be supplied with
control voltage and 400 Hz voltage.
Perform the lamp test.
If RS is switched ON, output indicators J1, J2, and J3 are on.
If ECS is switched ON, output indicator J4 is on.
