9) RPL23uC features
The RPL23uC can detect micro breaks on a single or three phase network. It has two output relays which operates in
opposition.
Relay 1 is inactive and relay 2 active during normal operation.
Relay 1 is active and relay 2 is inactive in micro breaks detection.
A RPL23uC configurable parameters are:
- The nominal voltage from 30 V to 600 V.
- The type of network, single or three phase.
- The micro breaks detection threshold from 0 to -70% of the nominal voltage.
- The activation delay from 0 to 5 s in 0.02 s steps.
- The deactivation delay from 0 to 600 s in 0.1 s steps from 0 to 99.9 s and 1 s steps from 100 s to 600 s.
10) RPL23peak features
The RPL23peak detects peak voltage overshoots on its three input voltage. It is fitted with two individual alarms inde-
pendently configurable relays. The relays operates in negative security, i.e. that they are excited when alarm is off. On
the front panel, the unit displays the max peak line voltage with a refresh delay of 2 seconds.
In alarm state:
- The value of the peak voltage which trigger the alarm status is stored and remains until its deactivation.
- The red LED R1 and/or R2 is lit to indicate the status of the alarm relay.
- The green LED L1, L2, L3 lights to indicate the phase on witch has occur the peak.
The configurable relay settings are:
- The peak detection threshold.
- The activation delay, configurable from 1 to 5 ms in 1 ms steps.
- The deactivation delay, configurable from 0.1 to 600 s in 0.1 s steps from 0 to 99.9 s and 1 s steps from 100 to 600 s.
To access the configuration just press the top button.
The message RELAY #1? is displayed.
The top button (<YES>) provides access to its configuration, the bottom button (<NO>) jump to the relay 2 rubric.
For the threshold access setting, the message displayed is:
PEAK VOLTAGE THRESHOLD?
For the activation/deactivation delays access setting the messages are:
ACTIVATION DELAY?
DEACTIVATION DELAY?
The top button (<YES>) provides access to the configuration of the parameter, the bottom button (<NO>) jump to the
next rubric. In the case of <YES> choice , the actual parameter value is displayed and blinks. The buttons (up/down)
permits to increment/decrement the value. The value is validated after a delay of 4 seconds when no buttons is pressed.
The default detection factory settings for the 2 relays are:
- Threshold = 0.7 * Input caliber, activation delay = 2 ms deactivation delay = 10 s.
11) RPL23Ho features
The RPL23Ho can be used to detect earth fault voltage on a three-phase network with neutral. It is fitted with two indi-
vidual alarms independently configurable relays. The relays operates in negative security, i.e. that they are excited when
alarm is off. The earth fault voltage (UHo) of the network or the single voltage of phase 1 (UL1) or 2 (UL2) or 3 (UL3)
can be displayed on the front panel. The displayed measurement is changed by pressing the bottom button.
In addition, various LEDs indicate the status of the device:
The LEDs "L1", "L2", "L3" are lit indicating the presence of the 3 phases (LED Lx is off in case of phase failure).
The LEDs "R1" and "R2" indicate the alarm status of relays 1 and 2 (lit in alarm, off out of alarm).
The configurable relay settings are:
- The earth fault voltage detection threshold.
- The activation delay, configurable from 0.1 to 600 s in 0.1 s steps from 0 to 99.9 s and 1 s steps from 100 to 600 s.
- The deactivation delay, configurable from 0.1 to 600 s.
