The settings 0, 1 and 2 means:
0 = means that any trip of the threshold is considered final trip.
The autoreclose will move in the lock status.
1 = trip on threshold pick up, followed by the programmed reclosing activity
2 = none trip on threshold pick up, and this one whatever in AUTOMAT.CRTL/Trip
Command submenu is set to ON. With this setting after that the tR is expired a ”Recloser
Successful” message is displayed on the LCD. The autoreclose is ready for a new cycles
sequence.
It can occur that instead of 0, 1 or 2 reading the setting on the LCD we find the symbol
▓
. It
means that the download setting regarding the configuration matrix by a remote program (S1
or other) was wrong.
In the above case none message is provided but the autoreclose does not operate for the
setting threshold error, if tI (inhibit time) is greater of the trip delay of the involved threshold
the ARC will move to the lock status. The ARC executes the normal cycles for the other
corrected settings.
NOTE: Pay attention to the ARC setting both in local and remote.
The set of the cycles number, phase or earth and the setting of the configuration matrix are
related each other strictly.
Below a setting example to define the ARC cycles number. The rule to define the available
cycles number is listed below.
It is valid both for the phase and earth thresholds using the thresholds Ie>, Ie>>, Ie>>>,
Pe/Iecos>, Pe/Iecos>>, tAux2.
1. To have at least an ARC cycle the right item must be equal to 1.
2. The presence of one has to be counted starting from right.
