Cabinet Temperature Query Test (#122)
FAIL VARIABLE-SPEED FAN ASSEMBLIES: One or more fans have stopped.
If none of the fans are running:
1. Resolve every alarm against CARR-POW (Carrier Power Supply).
S8700-series IP-PNC Resolve every alarm against RMC-ENV (Power/
Fan Sensors).
2. Verify that 48 VDC is available to the fan power filter at the J2F local
cable connector. The voltage range is -42.5 V to -52.5 V. There
should be 48 VDC between the following pin pairs: 2/3, 8/9, 10/11. If
-48 VDC is absent, replace the CFY1B current limiter card.
3. If there are 48 VDC at the power filter’s input, follow this procedure
to verify that there are also 48 VDC at the power filter’s output to
avoid damage to the fan alarm circuit. Note that the J2F/P2F
connectors on the power filter must be disconnected whenever
connecting or disconnecting the J2/P2 connectors on the fan
assembly.
a. Disconnect connector J2F from P2F on the top of the filter.
b. Disconnect J2 from P2 on the fan assembly.
c. Reconnect J2F to P2F on the filter. There should be 48 VDC
between the following pin pairs on the J2 connector: 2/3, 8/9,
10/11.
d. If 48 VDC is present, the fans should have power. Verify every
power connector is sound and making good contact. Be sure to
disconnect the J2F/P2F connector again before reconnecting
the J2/P2.
e. If not, replace the fan power filter using the previous procedure
described. Be sure to disconnect the J2F/P2F connector again
before reconnecting the J2/P2.
