controller does not detect nominal generator set AC
output voltage after crank disconnect. The local display
shows AC sensing loss.
Battery Charger Fault. The lamp illuminates when the
battery charger malfunctions. This fault feature requires
an optional battery charger with a malfunction output for
the lamp to function. Local display shows bat chgr fault.
Battle Switch. The lamp illuminates when in the battle
switch mode. The local display shows battle switch.

access the fault code. The engine operation manual
provides the fault code descriptions.
Emergency Power System (EPS) Supplying Load.
The lamp illuminates when the generator set supplies
more than 1% of the rated standby output current. The
local display shows EPS supplying load.
Ground Fault Detected. The lamp illuminates and the
alarm horn sounds when a user-supplied ground fault
detector signals the controller. The local display shows
ground fault.
High Battery Voltage. The lamp illuminates when the
battery voltage rises above the preset level for more

coolant temperature approaches the shutdown range.
The local display shows hi cool temp warning.
High Oil Temperature Warning. The lamp illuminates
and the alarm horn sounds when the engine high oil
temperatuare approaches the shutdown range. The local

Load Shed. The lamp illuminates when the generator
set’s total kW load exceeds the programmed level for
more than the load shed time. When the load shed alarm
sounds and resets more than twice in 1 minute, the load
