High Coolant Temperature. The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down
because of high engine coolant temperature. The high
coolant temperature shutdown does not function during
the preset inhibit time delay period after startup. The
local display shows Coolnt Temp High Shutdwn.
Note: The high engine temperature shutdown function
and the low coolant level shutdown function are
independent. A low coolant level condition may
not activate the high engine temperature switch.
Internal Fault. The fault lamp illuminates red, the alarm
horn sounds, and the unit shuts down when the internal
diagnostics detect a controller malfunction. The local
display shows Intern Error Shutdwn.
kW Overload. The fault lamp illuminates red, the alarm
horn sounds, and the unit shuts down when the
generator set supplies more than 102% of the rated
standby output kW (or 112% of the rated prime power
output kW) for more than 60 seconds. The local display
shows Total Power High Shutdwn.
Locked Rotor (failed to crank). If none of the speed
sensing inputs show engine rotation within the preset
time delay of initiating engine cranking, the ignition and
crank circuits turn off for the preset period and the cycle
repeats. The fault lamp illuminates red, the alarm horn
sounds, and the unit shuts down after the second cycle
of the preset period of cranking. The local display shows
Locked Rotor Shutdown.
Low Coolant Level. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down because of
low coolant level. Shutdown occurs 5 seconds after low
coolant level is detected. Local display shows Coolant
Lvl Low Shutdwn.
Low Engine Oil Level. The fault lamp illuminates red,
the alarm horn sounds, and the unit shuts down because
of low engine oil level. This fault feature requires an
optional low engine oil level sensor for the lamp to
function. Local display shows Oil Level Low Shutdwn.
Low Fuel Level (diesel-powered models only). The
fault lamp illuminates red, the alarm horn sounds, and
the unit shuts down when the fuel tank level on
diesel-fueled models approaches empty.
requires an optional low fuel level switch for the lamp to
function. The local display shows Fuel Level Low
Shutdwn.
TP-6694 7/11
Low Oil Pressure. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down because of
low oil pressure. The shutdown occurs 5 seconds after
the low pressure condition is detected. The low oil
pressure shutdown does not function during first the
30 seconds after startup. The local display shows Oil
Press Low Shutdwn.
Metering Communications Loss.

No Coolant Temperature Signal.
illuminates red, the alarm horn sounds, and the unit
shuts down when the engine coolant temperature
sender circuit is open. The local display shows Temp
Sig Loss Shutdwn.
No Oil Pressure Signal. The fault lamp illuminates red,
the alarm horn sounds, and the unit shuts down when
the engine oil pressure sender circuit is open for more
than 5 seconds. The local display shows Press Sig Loss
Shutdwn.
Overcrank. The fault lamp illuminates red, the alarm
horn sounds, and cranking stops when the unit does not
start within the defined cranking period.
display shows Over Crank Shutdwn. See Section 2.3.1,
Auto Starting, and Section 1.3.1, Status Event and Fault
Specifications for cyclic crank specifications.
Note: The controller is equipped with an automatic
restart function. When speed drops below 25 Hz
(750 rpm) while the engine is running, the unit
attempts to recrank. The unit then follows the
cyclic cranking cycle and, when the engine fails to
start, will shut down on an overcrank fault
condition.
Overfrequency. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down when the
frequency is above the overfrequency setting. The local
display shows Freq High Shutdwn. See Figure 2-4.
