All battery compartments should be checked periodically for proper operation. Take a known good pair of
batteries and install into the battery compartments. Ensure the power light activates with no intermittent
operation. If the power light will not activate look in the battery compartment and check the battery contact
for signs of excessive stress. Also check the condition of the 2A fuse wiring. If the problem persists,
remove the six screws holding the battery plate in place and lift upwards. On the bottom of the battery
plate you will see a small circuit board that extends the battery input to the power switch. Check the
connections to and from this board. Please contact Sensors & Software Inc. should all the above fail to
resolve the problem.
7.2 Testing Fibre Optic Cables
When troubleshooting problems with the system, error messages may indicate a problem with the
transmitter or receiver. Since the transmitter and receiver communicate with the control module using fibre
optic cables, it is possible that the problem may be because of damage to the fibre optic cables. Use the
fibre optic testing routine under System Setup - Acquisition Control - Fibre Optic Testing to test cables.
Setup the fibre optic cable as shown in Figure 7-5. The feedthrough connector located in the spare parts kit
(See Figure 9-1 on page 111). During the test, gently move the cable around, especially near the
connectors, to see if a failure occurs. If the cable fails at any time, even once, it should be repaired or
replaced. If the cable is going to be repaired, it is necessary to find the point of damage and cut the cable
off at this point. Then look at the section on repairing fibre optic cables (Section 9.6: P113).
Figure 7-5: Setup for fibre optic cable testing. Make sure that the cable is plugged into the control module receptacle number 4
and the loose ends of the cable are connected together using the feedthrough connector.
