So, it can be (un)blocked with the next options:
✓
From the HMI.
There are two specific keys marked 79 Block and Unblock, plus a specific signal
led, allowing recloser operation, blocking or unblocking it.
✓
From the HMI.
This command can be executed from the command menu.
✓
Via protocol.
This is performed via any means of communication. This is carried out as if it was
a command, and the normal conditions of any command must be met.
In all these cases, the equipment stores the block situation in the non-volatile memory, as the last
command must be known for a possible re-start.
The logic signal
Hot Line Tag
also affects the behaviour of this function. When it is activated, the function
is blocked, and reclosing is not permitted.
Also, this logic signal can be configured to change the Settings Groups through PGC. This can be useful
to achieve a fast tripping of protection functions in Hot Line Tag Mode.
The auto-recloser´s start up is shown in the following figure:
