Switch Function Factory
setting
SGB2/1 Switches SGB2/1...3 are used when the external control signal BS2 is to 0
SGB2/2 be used for blocking one or more of the current stages of the module. 0
SGB2/3 When all the switches are in position 0 no stage is blocked 0
When SGB2/1=1, the tripping of overload stages I
b
> and I
a
> are blocked
by the input signal BS2.
When SGB2/2=1, the tripping of phase unbalance stages ∆I
1
> and ∆I
2
>
are blocked by the input signal BS2.
When SGB2/3=1, the tripping of undercurrent stage I< is blocked by the
input signal BS2.
SGB2/4 External control of reconnection inhibit output using the input signal BS2 0
When SGB2/4=0, the external control is disabled.
When SGB2/4=1, the external control is enabled.
SGB2/5 When SGB2/5=1, the external trip command is carried out to output 0
relay A. External protective relays can be connected to the trip path using
this feature.
Note! The trip signalling is not handled by the SPCJ-module and must
be arranged using a contact on the external protective relay.
SGB2/6 Remote reset of the trip indicators 0
When SGB2/6=0, the trip indicators are not reset by signal BS2
When SGB2/6=1, the trip indicators are reset by signal BS2
SGB2/7 Remote reset of the trip indicators and output relays 0
When SGB2/7=0, the trip indicators and output relays are not reset
by signal BS2
When SGB2/7=1, the trip indicators and output relays are reset
by signal BS2
SGB2/8 When SGB2/8=1, an external relay reset is performed by input signal 0
BS2. This makes it possible to have a manual master reset button out-
side the relay. The same button can serve all relays on a station. Another
possibility is to link the reset to some automation.
