When a trip is forced (input terminals 1-2, by applying 230 V) the device is tripped and disabled
and an “EXT” message is shown on the display in red and also the LED is on. It has to remain
permanently in this situation until the change in status no longer exists. It is not possible to
manually reset or reset using communications.

When it is remotely reset (input terminals 1-2, removing the 230 Vac) the equipment is recon-
nected with the display backlit in green, LED ON in green as in normal status.
For the RGU-10C, a remote trip/reset can also be made via RS-485 communications. The de-
vice remains tripped showing this incidence on the display with a “REM” message in red with
also the LED ON. It has to remain permanently in this situation until the change in status no
longer exists.
