Procedure for checking power supply at place of installation.
1 Check the indication displayed on the front panel of the power supply unit:
a) The 230 V AC LED
should remain lit to indicate the presence of the mains supply
voltage.
b) The LEDs AUX 1
and AUX 2
should remain lit to indicate presence of
supply voltage.
2 Check the output voltage after 230 V power failure.
a) Simulate the lack of 230 V mains voltage by disconnecting the main circuit breaker.
b) The 230 V AC LED
should go out.
c) The LEDs AUX 1
and AUX 2
should remain lit to indicate the presence of
output voltage.
d) The LED ALARM LED
will start blinking.
e) The EPS technical output and ALARM will change to the opposite status after 10 seconds / 1 min / 10
mins / 30 mins, depending on the “EPS” parameter set in the PSU configuration menu (default setting:
10 seconds).
f)
Turn on the 230 V mains voltage again. Indication should return to the initial status from point 1 after a
few seconds.
3 Check whether the lack of continuity in the battery circuit is properly indicated.
a) During normal PSU operation (230 V mains voltage on), disconnect the battery circuit by disconnecting
the F
BAT
fuse.
b) Within 5 minutes the PSU will start signaling a failure in the battery circuit.
c) The ALARM LED
will start blinking.
d) The ALARM technical output will change status into opposite.
e) Turn on the FBAT fuse in the battery circuit again.
i)
The power supply should return to normal operation, indicating the initial status, within 5 minutes after
the battery test is completed.
