Engine Stalled
engine
Description
Engine was called to run but speed fell below 10 rpm, or alarm 00130 was ON and oil pressure switch contacts were open; shutdown and alarm.
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 F2 and F11. 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 and ensure there is unrestricted fuel flow through system. Check that the pump screen(s) are clean and the fuel is not gelled. c. Check fuel system prime and ensure there is no air in fuel system. 4. Check Engine Control Unit (ENCU) a. Check voltage from fuse F4 through PM-15 and SP-24 to ENCU-22. Verify correct fuse (see Figure 2.7) Must have minimum 11 VDC with the battery connected and SROS in the OFF position. b. Check voltage from PM-32 to SP-34. 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 5.2.4) and retest. c. Check for ground at ENCU-19 and PM-28 (at the negative battery cable connection). If ground not good, check connectors and wiring between terminals for damage, moisture or corrosion. d. Inspect engine speed sensor (ENSSN) and engine speed control unit (ENCU) connector pins and terminals. Verify that there is no physical damage to components, and no damage or corrosion in connectors.
