X CMC Fan9 Aux 476 The specified fan was not commanded to run but its
interposing relay status indicated that the fan was turned on.
Note: This warning is used exclusively on Heatpipe drives.
• Check fan feedback wiring and confirm with the electrical
drawings. Verify that XIO is functional.

(C-FRAME ONLY)
37 This warning is for liquid cool drives. The drive indicates that
the measured coolant conductivity is greater than 1 S/cm
3
.
Verify that there is no debris in the coolant, and replace the de-
ionizing cartridge if necessary.
• Verify that no foreign debris has entered the system (iron piping,
non-deionized water, etc.).
• There is no immediate need for action, but be prepared to change
the de-ionizing cartridge and run the system, verifying that the
conductivity is decreasing.
X Control Pwr Loss 112 This is used in the auto-restart feature algorithm as an indicator
to tell the drive to stop gating and wait for control power to
return. This alarm is for drives engineered with a UPS option.
There has been a loss or dip in the control power feeding the
drive for more than five cycles.
• Investigate reliability of the control power.
• Be sure the drive operates as expected when there is a control
power outage (UPS must be installed).
• Be sure that the power source is active and investigate the
reliability of the source.
