Soft Fail Message
Condition when indicator is lit
Corrective Action
Battery State Warning
Note that Battery State is
also indicated on the C300
Controller block Main tab.
Indicates that battery voltage for
controller RAM retention is not within
specified limits. Controller state may
not be maintained through a power
down. This would prevent warm start
and may require the user to reload
control strategies when power is
restored.
On the C300 block Main tab:
 If Battery Status =
UNDERVOLTAGE, then
replace battery.
 If Battery Status =
OVERVOLTAGE, make sure
that the battery used is of type
specified by Honeywell.
Device Index Switches
Changed
The Device Index switch changed
while the C300 Controller was
operating.
This condition would place the
controller at a different and
unexpected IP Address following a
subsequent controller restart.
Verify if the Device Index switch
setting is correct, reset if
necessary. Refer to the section
Reset Device Index and IP
address of a controller for the
detailed procedure.
If failure still persists, the IOTA
may be defective. Replace the
IOTA.
CHECK
Reset/reboot will cause module to
assume new/incorrect address. If
visibly correct, rotate each of them
360deg. If this corrects problem,
replace IOTA. Otherwise replace
module then IOTA.

procedure.
If failure still persists, replace the
controller module and return faulty
