Part of the starting and tripping signals of the
relay modules are permanently connected to
control the outputs, whereas others are linked
through switchgroup SGR situated at the front
edge of the I/O module SPTR 6B11. The
Switch Function
SGR/1 When SGR/1 = 1, the start signal SS1 of SPCJ 4D24 is routed to
output SIGNAL3
SGR/2 When SGR/2 = 1, the signals TS1 and TS2 of SPCJ 4D24 is routed
to output SIGNAL1
SGR/3 When SGR/3 = 1, the tripping signal of stage Iϕ> is linked to
output TRIP
SGR/4 No function in SPAC 536/636 C. Has to be in position 0
SGR/5 No function in SPAC 536/636 C. Has to be in position 0
SGR/6 No function in SPAC 536/636 C. Has to be in position 0
SGR/7 When SGR/7 = 1, all the signals connected to output TRIP are linked
to output SIGNAL1
SGR/8 When SGR/8 = 1, all the signals connected to output TRIP are linked
to output SIGNAL2
Note!
Switch SGR/3: When SGR/3 = 0 and the Iϕ>
stage trips, the trip signal opens output SIG-
NAL2 and gives an internal auto-reclose inhibit
signal. Thus the low-set earth-fault stage has a
signalling function only.
Switch SGR/7: When SGR/7 = 1 the output
SIGNAL1 can be used as a second trip output,
for instance, in applications with two circuit
breakers.
Switch SGR/8: When SGR/8 = 1 the output
SIGNAL2 can be used as a general alarm output
switches are set through the opening of the
system front panel.
The following functions can be selected with the
SGR switches:
for the protection relay modules, particulary
when the output SIGNAL1 is used as a second
trip output.
The operation of the outputs SIGNAL1 and 2
can be delayed 40 ms when they are used to
indicate that the overcurrent module and the
earth-fault module have operated. This delay
eliminates unnecessary signalling if auto-
reclosing is started by the tripping signals of the
relay modules. When an auto-reclose sequence
has started the internal signal ARDUE inhibits
the outputs SIGNAL1 and 2.
