Steps
Alarm/Cause
Corrective Action
130
CHECK ENGINE RPM SENSOR
•
TRIGGER–ON: When in Engine Operation only. If ambient temperature is above 32
°
F (0
°
C), and
this is the second or third start attempt, and the engine oil pressure switch is closed (oil pressure
good), and engine RPM is sensed at less than 1000;
OR
, if ambient is below 32
°
F (0
°
C) and the
DC amp draw is more than 2 amps, and this is the second or third start attempt, and engine RPM is
sensed at less than 1000.
•
UNIT CONTROL: Alarm Only and engine will be considered running.
•
RESET CONDITION: Auto Reset in Auto Start when engine speed is greater than 1,000 RPM or
alarm may be manually reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
1
Check Alarm List
Check for Alarm 41.
When alarms 41 and 130 occur at the same time,
generally, the engine has run out or is running out of
fuel. This causes the engine to surge. Check fuel in
tank and add fuel as necessary.
Check fuel lines between the fuel tank and the fuel
pump inlet to endure air is not being drawn in.
2
Check Engine Speed Sensor (ENSSN)
a. Inspect circuit from ENSCU
terminal 3 to microprocessor
connection 2MP18 & connector.
No damage to sensor or wiring.
No damage, moisture, or corrosion in connector.
b. Compare actual engine speed with
that shown on the display using
hand held tachometer.
Must be
±
20 RPM.
Must be a steady reading.
c. Check for 12 VDC between
ENSSN 12V terminal & ENSSN
ground.
Must be 12 VDC.
d. Check for 12 VDC at ENSSU
terminal 25 to ground
Must be 12 VDC.

Check Circuits With Test Sensor
Substitute known good sensor and
check Unit Data reading (Refer to
Section 3.13).
Must be within
±
20 RPM of reading on tachometer.
