Operation
REDs
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 and the Autotest are activated, when the sliding cover is
closed, i.e. to the left in the Auto On position (Fig. 2).
Test
REDtest
b
b
The REDtest carries out automatic testing of earth leakage protection every
months.
The test consists in opening and reclosing the REDtest, during which time
continuity of supply of the downstream installation is guaranteed.
Autotest:
after checking installation insulation, the REDtest monitors its residual
current device, without breaking the downstream power supply (bypass by bypass
contact).
d
This is onlypossible inmanualmode, i.e. slidingcover open in theAutoOff
position. You can thenmanually test thedevicebypressing theTest key.
Thedownstream installation is then temporarilybroken. Youmust then
manually reclose theREDby activating theO-l lever topower supply the
downstreamcircuit.
