RGU-10 RAL Electronic earth leakage protection relay with self-reclosing system
For instance, RGU-10 RAL supplied by 110 V a.c.
GENERAL DESCRIPTION
- Device with programmable differential relay with self-reclosing system. Symbol in LCD.
- It has 2 independents outputs by relays. Trip and locked by reclosing.
- It has 1 input for external Trip/Reclose. This input is opto - coupled.
- Mounting in Rail DIN 46277 (EN 50022) or panel 72x72 by mean accessory (M5ZZF1)
- Associated to a WG/WGS Series external , toroidal current transformer.
- It must be asociated to CONTACTOR like breaking element.
- It verifies connection with differential transformer WG/WGS by means inductive test.
- Leakage detection and measurement is via calculating its true efective value (TRMS).
- Display settings values and instant residual current to its accociated units.
DESCRIPTION LED AND BUTTONS.
- Shows equipment status via a display and 2 LED.
- 5 button equipment setup and setting.
- 2 button equipment TEST and RESET.
INDICATION BY LED AND DISPLAY.
- TRIP RELAY. LED and display signals a change
of status by changing from green to red.l
Display event type messages or values.
- BETWEN RECLOSURES.
The yellow LED is blinking. Red Display shows the
tripp cause fluctuating with partial reclosures No
- LOCKED BY RECLOSURES.
The yellow LED is fixed. The equipment arrives al
maximun number of reclosures established by the
self-reclosing sequence. Red display shows the cause.
- No OF RECLOSURES. By short press on PROG the display shows the number of reclosures by
earth leakage faults, partial and total number. The partial number are floating pages. In these
pages it can configure the self-reclosing sequence by press REC button.
RECLOSING THE EQUIPMENT.
- BY TRIP / LOCKED BY RECLOSURES
1. Automathic (earth leakage fault or manual). Is Shown on display
2. Manual reclose by pushing button RESET
3. External reclose sytem by remote or communications signal. When it forces a trip by remote
signal, only it can reclose by another remote signal.
In the case 2 and 3 the all partial counters of reclosures returns to a zero.

SENSITIVITY SETTING The same operation as above setting is carried out by pressing
- SIGNALLING CONTACTS RELAY STATE, std/+ . Select the default position of the relay contacts

and (+) 4-5 NC / 4-6 NO and appears the symbol in display.
- SELF-RECLOSING SYSTEM, REC. In reclosure partial numbers by press REC button we
configure the self-reclosing sequence referred at the page which it’s showing us. By default is
configured nº1 by earth leakage protection.

With the button the submenus are browsed PROG
and with the button the values to be selected
are displayed.
Press PROG to enter the value. The equipment
configures the value by displaying on “SAVE” por
the display and then exits Setting Mode.
If the keypad remains inactive for a certain time,
the equipment automatically exits Setting Mode
and displays without changing the setting “EXIT” .
