RGU-10 MT Electronic earth leakage protection relay with self-reclosing system
For instance, RGU-10 MT 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 not 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 a MCB motorized with or without a trip coil.
- 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, short ciruit-overload faults 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, short ciruit-overload faults or manual). Enabled.
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.
4. Manual reclose circuit breaker associated.
In the case 2 and 3 the all partial counters of reclosures returns to a zero.

and (+) 8-7 NC / 8-9 NA 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 nº10 by earth leakage protection and nº5 by short-circuit/overload protection.

¡ IMPORTANT !
The relay only self-recloses before a trip by earth leakage, short-circuit/overload current fault. The Test (red button) only
verifies the relay trips the protection. It recloses only by manual pressing RESET button.

SETUP SETTINGS
A long press in activates the SETUP settings. In this operating PROG
mode by pressing buttons and it shows the submenus and the PROG
setting values to modify . With thesePROG new setting values are
validated, the message SAVE is shown by display and exits setting
mode. In case of keypad inactive, it exits setting mode and the message
EXIT is shown by display wihtout changes.
In SEC.T it defines the working mode of outputs contacts relay 5-6. By
default 5-6 is normally open (St )
In TRIP (Circuit Breaker), The value is used when the CB don’t need a
trip coil. The value is used when CB needs one.
