Information:
Test each component of the electrical protection system in order to determine that all of the components work properly. Use the tables below to determine if the components are working properly. The tests should be performed on an engine that is started for the first time and at recommended service intervals. The service intervals are provided in the Operation and Maintenance Manual. If a problem occurs, refer to the index for the correct troubleshooting procedures. In order to determine the correct engine rpm, refer to the speed specification chart in the Testing and Adjusting section.Test 1 - Overspeed Switch (OS)
Table 1
Overspeed Switch (OS)
Step Engine RPM Action Correct Result
A 25 + 5 rpm less than 75% Overspeed Verify rpm Press the 75% Verify button No engine shutdown
B 25 + 5 rpm more than 75% Overspeed Verify rpm Press the 75% Verify button Air and fuel shutoff
C Manually reset the air shutoff lever at the top of the air inlet, if equipped. Press the ESS reset button. Test 2 - Emergency Stop Switch (ES)

Emergency Stop Switch (ES)
Step Engine RPM Action Correct Result
A Any rpm above the crank terminate rpm Press the push button for the emergency stop switch Air and fuel shutoff
B Manually reset the air shutoff lever at the top of the air inlet, if equipped. Turn ES switch in the dirction that is shown on the face of the push button in order to reset the switch. Test 3 - Normal Stop Switch (NSS)

Oil Pressure Switch (OPS2)
Step Engine RPM Action Correct Result
A 25 + 5 rpm less than the setting for the oil step speed Place a jumper across terminals OPS2-1 and OPS2-3. No engine shutdown.
B 25 + 5 rpm more than the setting for the oil step speed Place a jumper across terminals OPS2-1 and OPS2-3. Fuel shutoff 9 seconds after the oil step speed is reached.
C Remove the jumper from across terminals OPS2-1 and OPS2-3.
