Commissioning
Before wiring, open the battery breaker and the mains circuit-breaker
After the electrical connections are made (mains, loads and batteries).
1. Close the upstream mains circuit-breaker.
2. Check the load output voltage.
3. Close the battery breaker.
Your apparatus is in correct operation when the 3 LEDs on the front of the PSE are green.
If not, refer to chapter 8

A Mains
OK
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
+/-5%
as long as the charger
was switched off, <165V
+/-5%
if it was switched on.
If
the
mains fuse is blown or not present.
If
the charger is faulty.
If
the internal temperature is too high
B Battery
OK
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
C Output voltage
OK
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.
