ENGINE FAILED TO STOP
• ACTIVATION: When in Engine Operation, engine is turning more than 500 RPM for 20 seconds after unit
shutdown or cycled off or Oil Pressure switch is closed longer than 20 seconds after unit shutdown or cycle
off.
• UNIT CONTROL: Engine Operation: Engine and unit shutdown and alarm.
Electric Operation: This alarm will not activate in Electric Operation.
• RESET CONDITION: 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, clear the
alarm(s). (Refer to Note 1 in
Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check To Ensure Engine Is Running
Verify that engine is still running. Engine should not be running.
2.
Check Start/Run-Off Switch & Circuit
a. Check SROS. It must be in the OFF position.
b. Check two way communication equipment. It must not be wired so unit can start with SROS in the
OFF position. Correct wiring as needed.
c. Check voltage to 2MM
−
35: 0 VDC at 2MM-35 (including SP-24) and 3MM
−
16.
3.
Check For Alarm 00130 (Engine Speed Sensor)
4.
Check ENOPS
Check ENCU
−
15 to ENCU
−
18. It should be an open circuit when engine is not running
5.
Check Engine Control Unit (ENCU) and Fuel Speed Actuator (FSA)
a. Check voltage from fuse F3 through PCM
−
34 and SP
−
18 to ENCU
−
22. Verify correct fuse, see
. Must have minimum 11 VDC with the battery connected and SROS in the OFF posi-
tion.
b. Check voltage from 3MM-9 to ENCU
−
44. Must have minimum 11 VDC with SROS in START/
RUN. If not, energize the run relay output using component test mode (refer to
retest.
c. Check for ground at ENCU-19 and ENCUGND
−
A (at the battery negative cable connection). If ground
is not good, check connectors and wiring between terminals for damage, moisture or corrosion.
d. Inspect fuel/speed actuator (FSA), engine speed sensor (ENSSN) and engine speed control unit
(ENCU) connector pins & terminals. Verify there is no physical damage to components, and no
damage or corrosion in connectors.
e. Check resistance & amp draw of FSA. Refer to
f. Check FSA plunger. Must move in and out freely. Refer to engine manual.
