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
