Stephill Generators SSDP30-70 - DSE 6110 Fault Finding Guide

Common Fault Conditions

• Check E-stop has not been pressed in.
• Check E-stop switch wires are not loose.
• Check wiring is not open circuit - check for continuity between each side of the switch on the
back of the E-stop.
• Check that both wires on the E-stop have continuity to the corresponding positions on the
back of the DSE 6110 - wire No.2 & 3.
• Check that 12V is present across between position 3 and 1 on the back of the DSE 6110
module.
• Check oil level and fill to the correct level if necessary.
• Check engine oil pressure when running. On the DSE 6110 Engine page. (2 to 5 bar is normal)
• Check oil pressure sender and switch assembly including pipework - remove & clean - Oil &
filter change would be advisable.
• Oil switch fault - see below.
• Oil sender fault - see below.
• Check continuity between wire No. 43 on the oil switch to the DSE 6110 module (remove from
oil switch to test).
• Check for continuity between the oil switch body to the engine earth.
• To test the oil pressure switch first remove wire No.43 and link this wire to a clean earth point
on the engine. Start the generator, as soon as the engine starts to run remove the wire No.43
from the earth point. If the generator continues to run then this would indicate that the wiring is
good and the fault could possibly be the oil pressure switch.
• Replace oil sender.
• Check connections at the oil sender
• Check oil pressure sender and pipework - remove & clean - Oil & filter change would be
advisable.
• Check continuity between wire No.16 on the DSE 6110 to the oil sender.
• Check continuity between wire No.15 on the DSE 6110 to engine earth.
• Check continuity between wire No.1 on the oil sender to engine earth.
• Replace oil sender.
Fail to stop
• Check oil pressure switch and pipework - remove & clean - Oil & filter change would be
advisable.
• Check for loose wires on the oil switch.
• Check continuity between wire No.43 from the DSE 6110 to the oil switch.
• Replace oil switch.
