Troubleshooting Instructions
Before going through the check list below, refer to the connections and
operation procedures. Also check your system wiring schematic.
If any problems persist after you have made these checks, consult your
nearest Murphy facility.
1. Symptom: No display
a. Check that the miniature D-sub 9-pin connector (power and control
cable) is firmly connected to the back of the S1400 module. Check
the power and control cable for cracks or broken wire.
b. Check for power failure or power input shutdown.
NOTE: If after all of the above has been done, and there is still no dis-
play, return the S1400 module to us.
2. Symptom: Engine fails to start (Sensor switch fault display cannot
be cleared.)
a. Check that the miniature D-sub 9-pin connector (power and control
cable) is properly connected to the back of the S1400 module.
b. Check that the sensor input cable connector (ribbon cable) is
properly connected to the back of the S1400 module.
c. Check the display window for low battery voltage. A fading dis-
play will indicate loss of primary and backup power. To fully
charge the battery pack allow 24 hours with primary power ON.
NOTE: Backup battery package can only be replaced at the factory.
d. Check to see that LED lights are lit indicating relays are
functioning
e. Check that the 8 leads on the 8-point terminal block under the
Safety Barrier cover are connected and tight. (See drawing.)
f. Measure the voltage between terminals #1 and #2 on the 8-point
terminal block, (voltage should read between 5 VDC and 6 VDC).
Do this with the power input connected to power supply, and with
it disconnected. There should not be more than a 0.5 V difference
between the readings with the panel connected, and not connected.
NOTE: If shutdowns still result, send the complete system back to us.
TROUBLESHOOTING INSTRUCTIONS
WARNING: Do NOT open power supply until operations have been shut down and area has been rendered non-hazardous.
Do NOT run sensor wires in conduit with any other wire. Do NOT apply voltage to any annunciator input terminals. Do NOT bun-
dle sensor wires with any other wiring. Make sure the voltage and current requirements are within the S1400 system ratings.
