36.
If connected, verify that EPS Fault output shows a (com to n/c)
closed
contact and the GEN PSU Fault
output also shows a (com to n/c)
closed
contact.
37.
Disconnect one of the battery leads, ensuring that no exposed section of conductor or connector is
allowed to contact exposed metal-work, other PSE terminals, or other battery terminals.
38.
Verify that, in less than 1 minute the following conditions are met:

Reconnect the battery lead and, after approximately 3s, verify that that the Fault LED #3 does not flash.
(Audible click can be heard as the battery relay closes, then a second click while the charger is tested.)
Note: If it is necessary to obtain confirmation of charging current; between steps 28 and 29, an ammeter
can be placed in series with the battery leads. Continue to observe caution with all exposed conductors
when inserting or removing the meter and when restoring normal battery wiring

NSTRUCTIONS
In the event of loss of mains, a battery fault or a GEN fault, the corresponding Fault relay (signal) contacts
will open, and the LED indicators will display the fault condition and overall status of PSE.
If the output of the PSE fails, the cause of the failure should be investigated, also by referring to the ’
Status
and Fault-Diagnostic LED Indication‘
table, e.g. short circuit on load terminals or connection of a deeply
discharged battery. The fault should be rectified before restoring power to the PSE.
If any of the fuses require replacing, ensure the correct fuse rating and type is used – see page 2

AINTENANCE
This unit is intended for use by Service Personnel only. There are NO USER SERVICEABLE parts inside.
There is no regular maintenance required of the PSE other than periodic testing, and replacement of the
standby battery.
Reference should be made to the battery manufacturer's documentation to determine
typical/expected battery life with a view to periodic replacement of the battery.
