Engine Stalled
engine
Description
The engine was called to run but rpm dropped below 10 rpm, or with RPM sensor alarm on the oil pressure switch was open, and the unit shuts down and alarms.
Activation Conditions
The control system is calling for the engine to run, Engine speed sensor is good, and engine speed is less than 10 rpm; or Alarm 00130 Check Engine RPM Sensor is ON, and the oil pressure switch contacts are open.
Unit Behavior
Shutdown and alarm.
Reset Conditions
Auto Restart after 15 minutes, or Alarm may be manually reset using the display mounted keys or by turning the unit off, then back on again.
Corrective Actions
1. Check for Additional Alarms a. If this alarm is activated in conjunction with other alarms (00031 Failed to Start - Auto Mode, 05012 Check ENCU Power Circuit, 00078 Check SV1 Circuit, 00079 Check SV4 Circuit, 05013 Check Clutch Circuit, 00085 Check UL1 Circuit or 00086 Check UL2 Circuit) check F5 and F10. Fuses must be good. Replace fuse as required. Clear alarms, restart and check for repeat alarm(s). b. Check for alarm 00130 Check Engine RPM Sensor. When alarms 00130 and 00041 occur at the same time, generally the engine has run out or is running out of fuel. This causes the engine speed to surge and drop. Check fuel tank and add fuel as necessary. Check fuel lines between the fuel tank and the fuel pump inlet for air leakage. 2. Check Start/Run-Off Switch and Circuit a. Check SROS. Must be in the START/RUN position b. Check two way communication equipment. Must be set to allow operation and calling for operation. 3. Check Fuel System a. Check for Alarm 00001 Low Fuel Level Warning. Fill tank as needed. b. Check fuel flow. Unrestricted fuel flow through system. Pump screen(s) clean. Fuel not gelled. c. Check fuel system prime. No air in fuel system. 4. Check Engine Control Unit (ENCU) and Fuel Speed Actuator (FSA) a. Check voltage from fuse F3 through PCM-34 and SP-6 to ENCU-22. Verify correct fuse, see Figure 1.7. Must have minimum 11 VDC with the battery connected and SROS in the OFF position. b. Check voltage from 3MM-9 to ENCU-44. Must have minimum 11 VDC with SROS in the START/ RUN position. If not, energize the run relay output using Component Test mode (refer to Section 1.2.4) and retest. c. Check for ground at ENCU-19 and ENCUGND-A (at the negative battery cable connection). If ground 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 and terminals. Verify no physical damage to components, and no damage or corrosion in connectors. e. Check resistance and amp draw of FSA. Refer to Section 1.11 for specifications. f. Check FSA plunger. Must move in and out freely. Refer to engine workshop manual. Alarm continued on next page...
