Board LED
Controller failure, all
devices on the
communication bus
-R-
reporting loss of
communication with
controller.
Multiple rectifiers not
receiving ac power,
batteries are powering
load.
• AC input circuit
breakers have
opened.
•
AC input voltage is
out of range.
•
Internal rectifier
fault.
Rectifier output
voltage has fallen
below the battery on
discharge threshold
set by the user.
All rectifier outputs
have dropped below
36V, all rectifiers have
entered hiccup mode.
Defective controller.
One or both of the LVD
contactors is open;
someone
-A-
may have manually
opened LVD contactor.
One or more of the
output circuit
breakers or fuses have
opened.
Possible Solution(s)
Check controller to ensure it
is properly inserted into its
slot. If so, perform the
following steps:
1. Remove the controller
board for 1 minute and then
reset.
2. If problem persists, replace
controller with new
controller board.
3. If problem still persists, call
your local field
representative.
1. Verify ac power to rectifiers
is available.
2. Verify rectifier input circuit
breakers are closed.
3. If problem is not corrected,
replace rectifiers.
If commercial ac power is
present but the system
voltage remains low, call your
local field representative.
Investigate other alarms that
may be present such as
rectifier related
problems.
Remove controller; if output
voltage does not go to
set-point previously set by
user, call your local field
representative.
Place disconnect switch in
ON position.
Reset circuit breakers or
replace fuse.
