The second is AnyAlarmOut.val and it closes the contact if there is any alarm including the ones
in AlarmOut.val.
The physical connection for the first is made at the controller and the second is made at the
expansion module. Both are terminated at the same terminal, J12, located in the upper right
corner. There is both a normally open (NO6 to C6) and normally closed (NC6 to C6) option.

Alarm Number 0:
Error in the number of retain memory writings
This usually means indicates that the BMS is writing to a retained setpoint too often. Retained
values are stored in a special memory so that they are kept on power loss. Failure to correct
this could result in damage to the controller.
Alarm Number 1:
Error in retain memory writings
This usually means indicates that the BMS is writing to a retained setpoint too often. Retained
values are stored in a special memory so that they are kept on power loss. Failure to correct
this could result in damage to the controller.
Alarm Number 2:
Device Test is Running—Outputs Disabled!
This alarm occurs if someone had the unit in device test mode and the time limit has passed,
usually an hour. Either cycle power to the unit or go into the Device Test section in the password
protected menus and turn it off.
Alarm Number 3:
Device offline alarm to BMS
This alarm occurs if the BMS is enabled, and it is offline.
Alarm Number 4:
Device offline alarm CPCOE
This alarm occurs if the controller and expansion module have lost communication. For correct
operation the dipswitches are set (left to right) Forward, backward, forward, backward,
forward, forward, forward, forward. This coincides with an address of 5. Sometimes if they
have been moved around it is necessary to set them all to OFF (forward), cycle power, and then
set them as required, and then cycle power again.
NOTE: The green
LED indicates
communication
status on the BMS
port. If there is commu-
nication on the BMS port
(online) the green LED
flashes, if there is no
communication (offline) the
LED stays on steady.
