Description
Operation
The REDtest carries out automatic testing of earth leakage protection every seven
days.
The test consists in opening and reclosing the RCD, during which time continuity of
supply of the downstream installation is guaranteed.
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.
Residual current device
The REDtest 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).
Manual test and Autotest
There are two ways of testing earth leakage protection of the REDtest:
Manual test:
b
this is only possible in manual mode, i.e. sliding cover open in the
Auto Off position. 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 REDtest, by activating the O-l lever to power supply the downstream circuit.
Autotest:
b
after checking installation insulation, the REDtest monitors its residual
current device, without breaking the downstream power supply (bypass by bypass
contact). If the test is satisfactory, the right LED moves to green, while the left LED
remains OFF. If the system is faulty, the left LED moves to yellow and the faulty device
must be replaced.
