3 Control System
3.1 Control System Description
The control system is used to start and stop the generator set, and provides full
generator set monitoring capability and protection in a stand-alone situation (non-
paralleling) from the display screen. It monitors the engine for temperature, as well
as oil pressure and speed. It also provides voltage and current metering. In the
event of a fault, the unit indicates the fault type and, on critical faults, automatically
shuts down the generator set.
All indicators, control buttons, and the display screen are on the face of the operator
panel, as illustrated in the figure below.
There are three fault level signals generated by the control system:
• Event: Signals that a temporary condition exists.
• Warning: Signals an imminent or non-critical fault for the engine. The control
provides an indication only for this condition.
• Shutdown: Signals a potentially critical fault for the engine. The control
immediately takes the engine off-load and automatically shuts it down.
The standard control system operates on 12 (or 24 VDC if applicable) battery
power. History data is stored in non-volatile memory and is not deleted if battery
power is lost.
Standard Operator Panel
The operator panel includes indicator lights (LEDs), display buttons used to
navigate through the menus, control mode buttons, and an LCD display. The display
enables the operator to check the status, adjust the settings, and start and stop the
generator set. The standard operator panel (show below) is located on every
generator set. An optional in-home operator panel accessory is also available for
location inside the home.
