PRODUCT SENTRY PRESSURE GOVERNOR BY AMS
MESSAGE DESCRIPTION SENTRY RESPONSE OPERATOR ACTION
Coolant High
Temperature Fault
The Sentry has received high
coolant temperature diagnostic
message (bus warnings) or the
coolant temperature is greater
than the configured limit (user
warnings).
No change in operation.
Operator should cancel SENTRY
operation and determine the
cause of the high coolant
temperature fault.
Coolant High
Temperature
Warning
The Sentry has received high
coolant temperature diagnostic
message (bus warnings) or the
coolant temperature is greater
than the configured limit (user
warnings).
No change in operation.
Operator should cancel SENTRY
operation and determine the
cause of the high coolant
temperature warning.
Primary Twister
Communication
Timeout Fault
The SENTRY is not receiving
CAN communication from the
Twister device.
No change in operation.
Operator may continue to use
SENTRY but only presets and
idle will function.
Secondary
Twister
Communication
Timeout Fault
The SENTRY is not receiving
CAN communication from the
secondary Twister device.
No change in operation.
Operator may continue to use
SENTRY but only presets and
idle will function.
Intake Sensor
Fault
Signal voltage from the intake
pressure sensor is less than
+0.30VDC or greater than
+4.90VDC.
No change in operation.
Operator may continue to use
SENTRY in PRESSURE or
THROTTLE mode.
Operator should have the intake
pressure sensor and associated
wiring verified.
Discharge Sensor
Fault
Signal voltage from the discharge
pressure sensor is less than
+0.30VDC or greater than
+4.90VDC.
SENTRY switches to
THROTTLE mode operation.
Operator may continue to use
SENTRY in THROTTLE mode.
Operator should have the
discharge pressure sensor and
associated wiring verified.
Check Engine
Warning
The engine control unit is
reporting a check engine light.
No change in operation.
Operator may view the specific
warning and determine if
SENTRY operation should be
discontinued and the engine
turned OFF.
Stop Engine Fault
The engine control unit is
reporting a stop engine light.
No change in operation.
Operator may view the specific
fault and then discontinue
SENTRY operation and turn off
the engine.
Intake Pressure
not in Range to be
Zeroed
Signal voltage from the intake
pressure sensor is less than
+0.45VDC or greater than
+0.80VDC.
SENTRY will not allow the
intake pressure to be calibrated
to zero.
Operator should verify that the
intake pressure is actually zero.
Discharge
Pressure not in
Range to be
Zeroed
Signal voltage from the discharge
pressure sensor is less than
+0.45VDC or greater than
+0.80VDC.
SENTRY will not allow the
discharge pressure to be
calibrated to zero. Operator should verify that the
discharge pressure is actually
zero.
Water Supply
Insufficient
Pump discharge pressure
decreased 5 or more PSI as
engine speed was increased 120
or more RPM (while in pressure
mode).
SENTRY reduces engine speed
to 1100 RPM and attempts to
increase discharge pressure by
ramping engine RPM.
Operator should verify water
supply or change to THROTTLE
mode.
Discharge
Pressure Less
than 30 PSI
Pump intake pressure loss.
Discharge pressure dropped
below 30 PSI.
SENTRY maintains engine
speed at 1100 RPM for the
configured pressure time-out
(6.6.8).
Operator should verify water
supply or change to THROTTLE
mode.
