Regen Terminated

normally controlled by the service technician.
Regeneration Mode Status or Alarm messages
are generally intended for the service person.
This status message informs the user that Regen
Mode is no longer active.
This status message is self-clearing. When the
condition is no longer present, the alarm and any
control activity tied to the alarm reverts to normal.
Under normal circumstances, none.
If this message is active, and there is no clear
reason why the UPS was in Regeneration Mode, or
if the command to terminate Regeneration Mode
was not issued, contact your factory-authorized
service provider.

Remote Off BPSS.
This status message is self-clearing. When the
condition is no longer present, the message and

REPO Shutdown
The UPS shuts down in response to an active
Remote Emergency Power Off (REPO)
command.
Press “SILENCE” to silence the audible alarm.
Resolve the issue that precipitated the REPO.
For safety, the UPS latches an REPO event. There
are two ways to clear the latch:
1. Press the Reset pushbutton on the External
Interface Board (EIB).
2. From HMI front panel display, press OK button
when ” Press OK to Reset EPO Latched signal”
message is displayed
in a dialog box.
Verify the REPO is cleared by observing the REPO
alarm in the Active Event Window is gone.
Restart the UPS by pressing “Startup,” “Manual
Start,” and follow the prompts.
Restart in Process
Automatic Restart is in progress. This message
clears when the Automatic Restart sequence is
complete.
To complete the Automatic Restart, follow the
prompts on the display.
Restart Inhibited
Automatic Restart of the UPS is not allowed
because of an external signal.
Automatic Restart Inhibit is active when signaled
from an external source. The signal is wired into
Input Contact Interface (ICI 1).
Investigate and resolve the external signal forcing
the UPS to remain off.
If you do not have an ICI, or if there are no external
off signals input to the UPS, contact your factory-
authorized service provider.
