1. If none of the fans are running:
a. Look for and resolve all alarms against the
CARR-POW (Carrier Port Power Unit).
b. Verify that 48 volt DC is available to the fan units.
Check the fan unit wiring harness connector. Verify
that there is 48 volt DC between pins (3, 9, 11 and 2,
8, 10).
If there is 48 volt DC at the connector, there should be
power to the fans. If the fans are not running, replace
the AHD1. If the fans still do not run, follow normal
escalation procedures.
If there is not 48 volt DC at the connector, the current
limiter card (982LS) is probably defective. Replace the
current limiter card. If the fans still do not run, escalate
the problem.
2. If only a few of the fans are not running, replace the
defective fans.
3. If all the fans can be started, wait five minutes, and rerun
