Alternator Protection. The fault lamp illuminates red and
the unit shuts down because of an alternator overload or
short circuit. See Appendix D, Alternator Protection in the
Generator Operation Manual for more information.
Auxiliary Input (Shutdown). The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down
when an auxiliary digital or analog inputs signals the
controller. The digital inputs do not function during the
first 30 seconds after startup. Use SiteTecht software
to define inputs as shutdowns or warnings.
Common Fault. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down when the
controller is signaled by a common fault.
SiteTecht software to activate the common fault
shutdown. The common fault comprises of any
combination of the fault shutdowns under a single alert.
Coolant Temperature Open Circuit. The fault lamp
illuminates red, the alarm horn sounds, and the unit
shuts down when the engine coolant temperature
sender circuit is open.
ECM Communications Loss. The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down
when the ECM communication link is disrupted.
ECM Diagnostics (Multiple Engine Inputs). The fault
lamp illuminates red, the alarm horn sounds, and the
unit shuts down when ECM diagnostics signals the
controller. The specific display (xxxxx) will be a brief
message or fault code that is engine manufacturer
dependant. The engine literature provides the fault
code description and further information.
ECM Model Mismatch. The fault lamp illuminates red,
the alarm horn sounds, and the unit shuts down when
the controller detects an error with the ECM model.
Electrical Metering Communication Loss. The fault
lamp illuminates red, the alarm horn sounds, and the
unit shuts down when the metering to the controller
communication link is disrupted.
Emergency Stop. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down when the
local or optional remote emergency stop switch
activates.
Fuel Tank Leak. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down when the
fuel tank signals a leak of the inner tank. This fault
requires an optional fuel tank leak switch for the lamp to
function.
TP-6953 7/19
Generator Total Real Power High. 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.
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.
Note: The high engine temperature shutdown function
and the low coolant level shutdown function are
independent. A low coolant level condition may
Use
not activate the high engine temperature switch.
High Engine Speed. The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down immediately
when the governed frequency on 50 and 60 Hz models
exceeds the over speed setting.
High Exhaust Temperature. The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down
immediately when the engine exhaust temperature
exceeds the default setting.
High Intake Air Temperature.
illuminates red, the alarm horn sounds, and the unit
shuts down because of high intake air temperature. The
shutdown occurs 5 seconds after the engine intake air
reaches the temperature shutdown range. The engine
intake air temperature shutdown does not function
during the first 30 seconds after startup.
High Generator Frequency. The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down
when the frequency is above the overfrequency setting.

High Generator Voltage (Each Phase). The fault lamp
illuminates red, the alarm horn sounds, and the unit
shuts down when the voltage exceeds the overvoltage
setting for the preset time delay period. See Figure 2-9
