E. VOLTAGE ADJUST – The rheostat allows the user to “fine tune” the generator set’s voltage
output. It is normally used to adjust output voltage after switching the output of the generator set to a
different voltage.
F. METERS – These meters monitor and display the current operating parameters of the generator set.
The Voltmeter monitors and displays the current operating AC output of the generator set.
The Hertz Meter monitors and displays the current operating frequency of the generator set.
The ammeter monitors and displays the amount of current that is being delivered by the generator set.
This meter works in conjunction with the Voltmeter Switch (Item G) in determining which output leg
to monitor.
G. AMMETER SWITCH – The switch allows the user to switch between L1, L2 and L3 to monitor the
current in each output leg of the generator.
H. PANEL LIGHT – By turning on the panel light switch, the panel lights (Not pictured on diagram)
will be energized and will illuminate the control panel.
I – SYSTEM FAULT INDICATORS – These lights will come on when a fault condition or a warning
condition develops.
The “Low Oil Pressure” light will come on when the engine’s oil pressure drops below 15 PSI. This
condition will trigger a fault shut–down and the unit will stop.
The “Over–crank” light will come on when the engine has failed to start after four attempted crank
cycles. Each crank cycle consists of a 12 second time period followed by a 12 second rest time
period.
The “Over–speed” light will come on when the engine’s operating speed rises above it’s normal
operating parameters. This condition will trigger a fault shut–down and the engine will stop.
High Temperature light will come on when the engine’s operating temperature exceeds the safety
set–point.
