Tyco Electronics Galaxy SC Controller J85501F-1

CLC1 Clock Changed
A change has been made to Galaxy’s Time or
Date setting. This is a latched event, remaining
active until cleared by a user.
CLM1 Rectifier Current Limit
The rectifiers connected to the controller’s serial
bus have reached their current limit setting. Plant
voltage may, therefore, be lower than that
requested in Rectifier Manager.
CMA1 Minor Comm Fail Alarm
The controller has lost communication with a
device that it had previously recognized on its
rectifier/converter/BIC serial bus. If one of these
devices is to be permanently removed, it is
necessary to issue a Remove Rectifier, Remove
Converter, or Unmap BIC command to clear the
CMA1 alarm.
CMFA1 Multiple Converter Fail
Multiple converters connected to the controller’s
serial bus have failed. This threshold is
programmable.

A contactor controlled by the controller’s LVD
CN1 settings (usually used with all LVBD

instructed to be closed, closed if instructed to be
open).
CNF2 Contactor 2 Failed
A contactor controlled by the controller’s LVD
CN2 settings (usually used with all LVBD
contactors of a plant) is in the opposite state of
that it has been instructed to be in (open if
instructed to be closed, closed if instructed to be
open).
CNF3 Contactor 3 Failed
A contactor controlled by the controller’s LVD
CN3 settings (sometimes used with some of the
LVLD contactors of a plant) is in the opposite
state of that it has been instructed to be in (open if
instructed to be closed, closed if instructed to be
open).
CNO1 Contactor 1 Open
The contactors controlled by the controller’s LVD
CN1 settings (usually used with all LVBD
