Mains fault
Mains fault (normal source): signalled on the front of the PSE by a yellow LED and available on dry contact
with 5 sec delay (failsafe) for remote monitoring.
If the mains is not present or < 185 V
was switched on.
If the mains fuse is blown or not present.
If the charger is faulty.
If the internal temperature is too high
Battery fault (back-up source): signalled on the front of the PSE by a yellow LED and available on dry
contact (failsafe) for remote monitoring.
If the battery is not present (see chapter 5.2.1)
If the internal impedance is too high (see chapter 5.2.1)
If the battery voltage < 23,5 V ±3 %. resp. 47,0 V ±3 % mains present
Output voltage fault: signalled on the front of the PSE by a yellow LED and available on dry contact (failsafe)
for remote monitoring.
If no voltage on one or more output. All the nine outputs are checked.
Each dry contact is a three pole SPDT switch (C-NC-NO), allowing 1A @ 24Vdc or 0,5A @ 120Vac.

Summary of available equipment

5.2.1

Battery test

The battery presence test is performed in the following manner: every 30 seconds for the first 20 minutes after
commissioning and every 15 minutes after. As soon as a fault is detected, the test is performed every 30
seconds until 20 minutes after the fault disappears.
The impedance measurement test occurs every 4 hours if the mains is present on the power supply and if his
current is < 12A. The impedance limit value is 13 mΩ
5.2.2

Temperature compensation:

A battery voltage compensation system maintains the charge characteristics within the limits specified by the
battery manufacturer across the entire operational temperature range.
5.2.3

Battery low voltage protection:

The battery low voltage protection threshold is 21,6 V
-
(SON 48V 12A MS150 RACK).
The element causing the cut-out will be in the + position.
-
5.2.4

Battery reverse connection protection

At start-up : the battery relays will not close
-
During operation : the fuse F8 will blow out
-
In order to ensure maximal and durable service, we strongly recommend that your product be maintained
clean and ensure that it is installed in a dry and ventilated location. We shall in no case be liable for damages
associated with improper use or incorrect maintenance of the equipment.
Replacing the original battery with a battery of incorrect type may result in an explosion hazard.
Used batteries must be disposed of in compliance with recycling requirements.
