Steps
ALARM / CAUSE
CORRECTIVE ACTION
130 CHECK ENGINE RPM SENSOR
•
TRIGGER–ON: Engine mode only. This alarm does not activate in standby.
In Auto Start, after the 2nd or 3rd start attempt the Engine Oil Pressure switch is closed (oil pressure
good) and engine RPM are sensed at less than 1000 RPM;
NOTE: This alarm can only be triggered during the engine starting sequence and during the 20 seconds
NOTE: This alarm can only be triggered during the engine starting sequence and during the 20 seconds
immediately following.
•
UNIT CONTROL: Alarm Only and engine will be considered running.
•
RESET CONDITION: Auto Reset in Auto Start when engine RPM are greater than 1,000 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
a. Check for Alarm 41
When both Alarm 41 and (usually) Alarm 130 are present,
there is insufficient fuel to run engine.
2.
Check Engine RPM Sensor
a. Inspect Engine RPM Sensor &
connector
No damage to sensor
No damage, moisture, or corrosion in connector
b. Compare actual engine RPM with
those shown on the display using
hand held tachometer.
Must be
±
20 RPM
Must be a steady reading.
3.
Check Engine RPM Sensor Wiring
a. Inspect harness & control box
connector pins & terminals (See
wiring schematic)
See Note 6
No physical damage to harness.
No damaged or corroded pins
b. Check RPM wiring
Energize circuit (see Note 2). DO NOT START UNIT.
c. Check voltage reading between plug
terminals A & B.
With + lead on A and -- lead on C reading should be
5 VDC
±
.2 volts. If it is not, check for grounded positive
circuit at CSP and CDP transducers.
4.
Check Circuits With Test Sensor
a. Substitute known good sensor and
check Data reading.
Must be within
±
20 RPM or reading on tachometer
