GENERAL DESCRIPTION
- Device with programmable differential relay with self-reclosing system. Symbol
- 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.

SELF-RECLOSING SYSTEM
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.
The relay only self-recloses after a trip by earth leakage current fault. The Test (red button) only verifies the relay trips
the protection. It recloses only by manual pressing RESET button.
