2. On the platform control box, ensure the generator switch is in the off position .
3. Select the start position on the start/emergency power switch until the engine starts .
4. Turn the generator on/off switch to the on position .
5. Connect a multimeter to the platform power outlet.
6. Note the voltage and frequency.
Adjust the Frequency and Voltage
1. Loosen the generator control valve jam nut.
2. Turn the control valve screw with an allen head wrench. Turning it counterclockwise (out) increases voltage
and frequency, turning it clockwise (in) decreases voltage and frequency.
3. The output must be:
ANSI/CSA
â–ª
Voltage: 104.4 VAC to 127.2 VAC
â–ª
Frequency: 57 Hz to 63 Hz
CE & AS
â–ª
Voltage: 207.0 VAC to 243.8 VAC
â–ª
Frequency: 47.5 Hz to 52.5 Hz
4. Tighten the jam nut when the correct output is achieved.
