Hardware failures after the unit has been properly installed and running can
be isolated by substituting a known good unit in to the system. If the problem
goes away, the fault lies with the removed board. Note the pin, signal or com-
mand that fails and contact ICS for repair information. See paragraph 5.9 for
repair instructions. If the fault persists, check the wiring especially any flat
ribbon cables for faulty or open connectors and the devices connected to the
interface board for possible faults.
.
WARNING
If the fault isolation procedure requires internal
measurements, always remove power when dis-
assembling or assembling the unit. Use extreme
caution during troubleshooting, adjustments, or
repair to prevent shorting components and causing
further damage to the unit.
