Figure 6-31. Test Setup (Typical), Electric Governor Control Unit
50/60 Hz Module. See Figure 6-32.
Start the engine and operate at 1800 rpm and no load.
Using a multimeter set to 0 to 2.5 V dc scale, measure voltage from terminal J to terminal 3.
Multimeter should indicate a slight positive (+) voltage from terminal J to terminal 3.
Set FREQUENCY SEL. SW. S118 to 50 Hz.
Multimeter should indicate zero volts.
Replace a 50/60 Hz module which fails this test.
High voltages and currents appear at load sharing panel A104 terminals 1
through 9. Observe safety precautions applicable to maintenance on high
voltage equipment Failure to do so may result in injury or death.
