PRODUCT FUNCTIONS

The restart function consists of automatically reclosing the differential
switch if it uncouples unexpectedly due to a temporary electrical
phenomenon (lightning, disturbances, etc.).
Before closing the switch, the device checks for earth failures or circuits
downstream. If it detects a failure, it goes into wait status; otherwise it
closes the switch.
If the device goes into wait status, it checks that there are no faults every
15 minutes. If the check gives a positive result, the device closes the
switch otherwise it goes into wait status.
After a third cut-in of the differential switch within three minutes of a
previous automatic reset, the device goes into locked status.
To re-enable the restart function, open the hatch, raise the differential
switch lever to position "I" and close the hatch.
If the differential switch will not remain in position "I", stop trying and
call a specialised technician to check the system.
The restart function cannot be activated when the differential switch is
open; to activate it the differential switch lever must be raised to
position "I" and the hatch closed. The test key and the differential
switch lever cannot be accessed when the functions are active.
