SOLUTION
It is recommended to replace the batteries of the CPS,
since they ate no longer able to maintain the charge for
a sufficient autonomy.
Warning: The replacement of the batteries must be
carried out by qualified personnel.
Activate the maintenance bypass (SWMB) without
switching off the CPS. This way, the fans will cool the
heat sink more rapidly. Eliminate the cause of the
overtemperature and wait for the temperature of the
heat sink to drop. Exclude the maintenance bypass.
Insert the maintenance bypass (SWMB) without
switching off the CPS, so that the fans, while keeping
running, cool the heat sink more rapidly and wait for the
temperature of the heat sink to drop. Turn the CPS off
and back on again. Exclude the maintenance bypass
and if the problem persists, contact the nearest service
centre.
Eliminate the cause of the overtemperature.
Open the battery fuse holder isolators (SWBATT) and
wait for the temperature of the battery charger heat sink
to drop.
Close the battery fuse holders. If the problem persists,
contact the nearest service centre. WARNING: never
open the SWBATT fuse holders during battery
operation.
Activate the maintenance bypass (SWMB). Switch off
the CPS, wait for a minute and turn the CPS back on.
Exclude the maintenance bypass and if the problem
persists, contact the nearest service centre.
Close Manual Bypass (SWMB) keeping closed INPUT
and OUTPUT switches.
Open input switch (SWIN and SWBYP) and wait until
CPS is completely turned OFF.
Turn ON SWIN and SWBYP again and verify display
regular operation. Exclude the maintenance bypass. If
the fault persists, contact the nearest technical support
centre.
Activate the maintenance bypass (SWMB). Switch off
the CPS, wait for a minute and turn the CPS back on. If
the display does not turn on or if the sequence fails,
contact the nearest service centre, leaving the CPS in
manual bypass mode.
Check the battery polarity. Contact the support centre if
the error persists.
