Operating
The RPL23 continuously measures L1, L2 and L3 voltages on three-phase networks or L1/N voltage on single phase
networks or the continuous DC voltage between L1 & L2. Then it enable or disable its internal components, depending
of configured alarms and detected faults.
In normal three-phase operation:
- LEDs L1, L2, L3 are lit, indicating the presence of the 3 phases (Lx LED is off in case of phase failure).
- ‘’Over V.’’ and ‘’Under V.’’ LEDs are off.
- Phases sequence LED is on (correct phase order).
- C1/T1 and/or C2/T2 (C3/T3 in option) contacts are closed.
- The mean value of the 3 RMS star input voltages is displayed.
In normal single phase AC or DC voltage operation:
- L1 LED is lit, L2, L3 LEDs are off.
- ‘’Over V.’’ and ‘’Under V.’’ LEDs are off.
- Phases order LED is off.
- C1/T1 and/or C2/T2 contacts are closed.
- The L1/N RMS input voltage or the L1/L2 DC voltage is displayed.
In case of overvoltage, over frequency (AC voltage) and/or under voltage, under frequency (AC voltage):
- ‘‘Over V. ‘’ and/or ‘’Under V.’’ LEDs are lit.
- For a over/under voltage alarm, Lx LED of phase failure is blinking.
- For a over/under frequency alarm, Lx LED of phase failure is lit fixed.
- C1/T1 and/or C2/T2 contacts are open.
- The overvoltage / under voltage level which trig the alarms is viewed on display : +10% or -6% (max +/- 99%).
In the event of an over / under frequency alarm, the device continue to display the voltage measurement.
In case of asymmetry alarm (three-phase only):
- ‘‘Over V. ‘’, ‘’Under V.’’ , L1, L2 and L3 LEDs are blinking synchronously.
- C1/T1 and/or C2/T2 relays contacts are open.
- The asymmetry level which trig the alarms is viewed on display : #10% (max = #99%).
In case of reverse phases order detection (three-phase only):
- Phases order LED is off.
- C3/T3 relay contact is open (only if /Po option).
