Information:
for approximately 2.5 seconds.Results:
OK - The voltage measures 24 3 VDC for approximately 2.5 seconds. The circuit is operating correctly to this point.Repair: Check the wire H708 from terminal A of the connectorfor the air shutoff solenoid for continuity to the −Battery terminal. If the wire H708 to the −Battery terminal is OK, replace the air shutoff solenoid.STOP
Not OK - The voltage did not measure 24 3 VDC for approximately 2.5 seconds. System voltage was not available at the solenoid connector.Repair: Repair the wire G708 between the connector for the air shutoff solenoids and terminal I at connector P-C1 of the rigid harness.STOPTest Step 8. Check the Voltage at the Contact of Relay "R3A"
Turn the ECS to the OFF/RESET position.
Disconnect wire T120 from terminal 87 of relay "R3A".
Connect a voltmeter between terminal 87 of relay "R3A" and the engine ground.
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the customer's emergency stop switch.
Reconnect wire T120.Expected Result:The voltage measures 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC. Proceed to Test Step 9.
Not OK - The voltage did not measure 24 3 VDC. Proceed to Test Step 11.Test Step 9. Check the Voltage at Terminal 6 of the Connector for the Timer
Turn the ECS to the OFF/RESET position.
Connect a voltmeter between terminal 6 of the connector for the timer and engine ground.
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the customer's emergency stop switch.Expected Result:The voltage measures 24 3 VDC for approximately 2.5 seconds.Results:
OK - The voltage measures 24 3 VDC for approximately 2.5 seconds. Proceed to Test Step 12.
Not OK - The voltage did not measure 24 3 VDC for approximately 2.5 seconds.Repair: Check for 24 3 VDC on terminal 3 of the connector for the timer. If voltage is not
