5.0 Troubleshooting
5.1 General
It is highly recommended that a spare sensor be on hand at all times. General Moni tors ’
sensors are the most reliable, longest life, catalytic bead sensors available. Sensor failure
tends to be one of the potential causes of real downtime. A full complement of other GMI
recommended spare parts should also be on hand (Section 7.7).
In the event the system is to have less than four active channels, Part Number 10102-1
(sensor simulator) must be substituted for each unused channel. Otherwis e, t he Fault
LED indicator for the unused channel will remain lit.
It is recommended that defective controllers be returned to the factory for repair, ev en if
the warranty has expired.
5.2 Troubleshooting Table
The inf ormation presented in the following table is designed to correct the more common
problems, which appear during system startup and operation. Should the various actions
suggested in the table fail to restore normal operation, we recommend that the factory be
consulted and, if necessary, that the system be returned to the factory for repair.
This section is intended to be a guide in correcting problems that may arise i n t he f i eld.
This section is not all-inclusive, and General Monitors should be contacted for assistance,
if the corrective actions listed do not eliminate the problem. If equipment o r qualif i ed
personnel required for various tests is not available, it is recommended that the defective
unit be returned to General Monitors for repair. A complete written description of the
problem should be included.
Be sure to disconnect external alarm wiring before making any check that might send the
unit into alarm, as an alarm condition will create problems.
NOTE: If the equipment is under warranty, any repairs performed by persons other than
General Monitors’ authorized personnel may void the warranty. Please read t he
warranty statement carefully.
