alternator the operator is able to set the Show Alt Excite Warning to No to allow for the pulsing without
feedback. If the alternator is self-exciting or this output is not needed the control can be set to Disable to
ensure no voltage is live on the output.
Alt/Excite Control (High Security) : allows the operator to enable or disable the dedicated output
for Alt Excite. Factory set to Enable
Alternator Excite Alert (High Security) : allows the operator to select if Alt Fail is a warning or
shutdown. Factory set to Warning.
Show Alt Excite Warning (High Security) : allows the controller to ignore the warning if excitation
of the alternator is not sensed to eliminate the Alt Fail Warning.
Factory set to Yes
Alt Excite Frequency
(High Security)
:
allows the operator to set how the Alternator excite out
behaves. During setup for the engine the operator can choose Pulse 50ms, Pulse 100ms, or
Steady for the frequency the alternator excite output turns on for exciting the field on a non-self-
exciting alternator. The Alt Failure Warning will only work with the pulse setting. If setting to Steady
(on during all running states) the Show Alt Excite Warning will need to be set to No. Factory set
to Pulse 50ms
ECU Shutdowns (High Security): allows the controller to not shutdown the engine if a red lamp status
(reserved for shutdown) is broadcast across the CANbus. When set to ECU Only the controller will show
the fault while completely relying on the engine to shutdown the engine when the fault is broadcast on the
CANbus. When set to Controller and ECU the controller will turn off the ECU enable output when a red
lamp status is broadcast on the CANbus. Factory set to Controller & ECU .
Frequency
AC Frequency (Medium Security) : Allows the operator to choose the operating frequency of the generator.
50 or 60 Hz. Factory set to 60 Hz
Run Speed
(Medium Security)
:
Allows the operator to choose the operating engine RPM of the generator.
Factory set to 1800 RPM
Low Frequency Action (Medium Security) : Allows the operator to choose the action when a low frequency
occurs. Not Used/Warning/Shutdown. Factory set to Shutdown
Low Frequency Value (Medium Security) : Allows the operator to choose the setpoint for the low frequency
alarm. Factory set to 55 Hz.
Post Lockout Timer (Medium Security) : Allows the operator to choose the amount of time to ignore the
low frequency alarm on start up. Factory set to 5 sec
High Frequency Action
(Medium Security)
:
Allows the operator to choose the action when a high
frequency occurs. Not Used/Warning/Shutdown.
Factory set to Shutdown
High Frequency Value (Medium Security) : Allows the operator to choose the setpoint for the high
frequency alarm. Factory set to 65 Hz.
Abnormal Frequency Threshold, Electronic Engines Only (Medium Security) : A shutdown will occur if
the frequency is within this % of the running frequency and 0 rpm is being broadcasted. This occurs on
shutdowns and startups. Factory set to 20 %
Frequency Out of Range Timer Value (Medium Security) : Allows the operator to choose the amount of
time the frequency is out of range high or low. Factory set to 1 sec
