switches on the PC boards and the SGR switches
of the I/O module are set as above and the

Function
Alerts the auto-reclose functions
Prevents AR1 from starting initiated by the high-set phase
overcurrent stage
Starts AR1 initiated by tripping of the overcurrent module
Starts AR1 initiated by tripping of the earth-fault module
Sets AR1 starting time at 0.0 s, AR initiated by tripping of the
overcurrent module
Sets AR1 starting time at 0.0 s, AR initiated by tripping of the
earth-fault module
Sets AR1 dead time at 0.3 s
Prevents starting of AR2 initiated by tripping of the high-set stage
of the overcurrent module
Does not start AR2 initiated by tripping of the overcurrent module
Starts AR2 initiated by tripping of the earth-fault module
Sets AR2 starting time at 0.0 s, AR initiated by earth-fault module

Stores the input parameters
functions will be blocked by the high-set stage.
The tripping signal from the low-set stage of the
phase overcurrent module will start a HSAR
sequence and the tripping signal from the neu-
tral overcurrent module both a HSAR and a
DAR sequence.
