Circutor REC 4 - System Management; Restarting the Reclosing System; Restart in Case of Blocking

If the time between a reclosure and the next trip is greater than the restart time, the reclosing attempts
start over at zero.
The delay and restart times depend on the number of attempts the reclosing device has made, as
shown in Table 7.
Table 7: Delay and Restart Times.

The leakage current will be supervised by measuring the resistance downstream of the tripped RCCB.
4.5.2.2.- Restarting the reclosing system meter
There are two ways to restart the internal reclosing system meter:
- Manually, by moving the mode selector switch from ON to OFF position and back to ON.
- Automatically, when the restart time elapses after the last reclosing without tripping again.
4.5.2.3.- Restart in case of blocking
In case of blocking of the device, the start-up sequence is:
1.- Check installation.
2.- Put the mode selector switch in Manual Mode (OFF).
3.- Lift the RCCB cover.
4.- Put the RCCB contact in ON mode.
5.- Lower the RCCB cover.
6.- Put the mode selector switch in Manual mode (ON).
Note: The switch has an M2 hole where you can attach a seal or a padlock to block access to the RCCB
and any other attempts at manual reclosing (Figure 7).
