Setting Notes

General
If the internal automatic reclosure function is to be used, the type of reclosure must be selected during the con-
figuration of the functions (Section 2.1.1.2) in address 133 Auto Reclose the AR control mode and in address
134 the AR control mode.
Up to 8 reclosure attempts are allowed with the integrated automatic reclosure function. Whereas the settings
in the addresses 3401 to 3441 are common to all reclosure cycles, the individual settings of the cycles are
made from address 3450 onwards. It is therefore possible to set different individual parameters for the first four
reclose cycles. From the fifth cycle onwards the parameters for the fourth cycle apply.
The automatic reclosing function can be turned ON or OFF under address 3401 AUTO RECLOSE.
