Operation
Recloser
The built-in automatic recloser automatically recloses the residual current device
after checking insulation of the downstream circuit. If the circuit is faulty, then RCD
reclosing is prohibited. After a 15-minute time delay, downstream circuit insulation is
checked again.
There are then two possibilities:
The installation is still faulty: in this case a new check will be carried out in
b
15 minutes. The sequence is locally reported by a 5-second intermittent red Led
and remotely reported by the auxiliary contact.
The fault was temporary and has disappeared: the recloser automatically recloses
b
the RCD
Residual current device
The REDs operates in the residual current device mode without automatic restart
when the sliding cover is open, i.e. to the right in the Auto Off position (Fig. 1).
The automatic restart mode is activated when the sliding cover is closed, i.e. to the
left in the Auto On position (Fig. 2).
Test
This is only possible in manual mode, i.e. sliding cover open in the Auto Off position.
b
You can then manually test the device by pressing the Test key. The downstream
installation is then temporarily broken. You must then manually reclose the REDs
by activating the O-l lever to power supply the downstream circuit.
