Fault signalling occurs with three LEDs at the front side as well as three fail-safe outputs on

the rear panel for remote monitoring (refer to section 3.4.2 ).

Status LED Green Yellow

A Mains status OK - Mains voltage threshold <165 Vac ±5% (Auto

reconnect at >185 Vac ±5%).

- Primary fuse (F1) is blown.

- Power supply is broken.

- Internal battery charger temperature is too high

(>65°C).

B Battery status OK - The battery is not present.

- The internal impedance (Ri) is too high

(see section 5.1 and 8.1.1 ).

- When the mains is present and the battery voltage

during normal use is:

PLN-24CH12: <23.5 Vdc ±3%

PRS-48CH12: <47,0 Vdc ±3%

- When the mains is present and the battery voltage

during start-up is:

PLN-24CH12: Vbat ≤ 14 Vdc, Vbat ≥ 30 Vdc (±3%)

PRS-48CH12: Vbat ≤ 40 Vdc, Vbat ≥ 60 Vdc (±3%)

- When battery is connected in reverse when

commisioning the system

C Output voltage status OK - No voltage on one or more output.
