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).

The RPL23 is entirely configurable in front face. Configuration access is done by pressing the top button.
For each configuration rubric, a message scrolls on display.
The top button (<YES>) allow to access to parameters setting of a relay or validate the corresponding function.
The bottom button (<NO>) allow to switch to the next rubric or disable the corresponding function.

When setting a parameter value, the top button allow to increment and the bottom button to decrement the value. While

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:

10) RPL23peak features

The RPL23peak detects peak voltage overshoots on its three input voltage. It is fitted with two individual alarms inde­pendently 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:

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 indi­vidual 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.

1) Introduction

To meet its policy concerning EMC, based on the Community directives 2014/30/EU & 2014/35/EU, the
LOREME company takes into account the standards relative to this directives from the very start of the con­ception of each product.
The set of tests performed on the devices, designed to work in an industrial environment, are made in accor­dance with IEC 61000-6-4 and IEC 61000-6-2 standards in order to establish the EU declaration of confor­mity. The devices being in certain typical configurations during the tests, it is impossible to guarantee the re­sults in every possible configurations. To ensure optimum operation of each device, it would be judicious to
comply with several recommendations of use.

2) Recommendations of use

2.1 ) General remarks

- Comply with the recommendations of assembly indicated in the technical sheet (direction of assembly,
spacing between the devices, ...).

- Comply with the recommendations of use indicated in the technical sheet (temperature range, protection
index).

- Avoid dust and excessive humidity, corrosive gas, considerable sources of heat.

- Avoid disturbed environments and disruptive phenomena or elements.

- If possible, group together the instrumentation devices in a zone separated from the power and relay cir­cuits.

- Avoid the direct proximity with considerable power distance switches, contactors, relays, thyristor power
groups, ...

- Do not get closer within fifty centimeters of a device with a transmitter (walkie-talkie) of a power of 5 W, be­cause the latter can create a field with an intensity higher than 10 V/M for a distance fewer than 50 cm.

2.2 ) Power supply

- Comply with the features indicated in the technical sheet (power supply voltage, frequency, allowance of the
values, stability, variations ...).

- It is better that the power supply should come from a system with section switches equipped with fuses for
the instrumentation element and that the power supply line be the most direct possible from the section
switch.

- Avoid using this power supply for the control of relays, of contactors, of electrogates, ...

- If the switching of thyristor statical groups, of engines, of speed variator, ... causes strong interferences on
the power supply circuit, it would be necessary to put an insulation transformer especially intended for instru­mentation linking the screen to earth.

- It is also important that the installation should have a good earth system and it is better that the voltage in
relation to the neutral should not exceed 1V, and the resistance be inferior to 6 ohms.

- If the installation is near high frequency generators or installations of arc welding, it is better to put suitable
section filters.

2.3 ) Inputs / Outputs

- In harsh conditions, it is advisable to use sheathed and twisted cables whose ground braid will be linked to
the earth at a single point.

- It is advisable to separate the input / output lines from the power supply lines in order to avoid the coupling
phenomena.

- It is also advisable to limit the lengths of data cables as much as possible.
