Switch Function
SGB1/1 Switches SGB1/1...3 are used when the external control signal BS1 is to
SGB1/2 be used for blocking one or more of the current stages of the module.
SGB1/3 When all the switches are in position 0 no stage is blocked
When SGB1/1=1, the tripping of overload stages I
by the input signal BS1.
When SGB 1/2=1, the tripping of phase unbalance stages ∆I
are blocked by the input signal BS1
When SGB1/3=1, the tripping of undercurrent stage I< is blocked by the
input signal BS1.
SGB1/4 External control of reconnection inhibit output using the input signal BS1
When SGB1/4=0, the external control is disabled.
When SGB1/4=1, the external control is enabled.
SGB1/5 When SGB1/5=1, the external trip command is carried out to output
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.
SGB1/6 Latching function for the trip signal TS2 of overload stage I
When SGB1/6=0, the trip signal returns to its initial state, i.e. the output
relay drops off, when the measuring signal causing the operation falls
below the starting level.
When SGB1/6=1, the trip signal remains on, i.e. the output relay operates
although the measuring signal falls below the starting level. Then the trip
signal of overload stage I
and PROGRAM push-buttons simultaneously. (also by signal BS1. Note
switch SGB1/8). When the display is off the signals can also be resetted
by pressing only PROGRAM.
SGB1/7 Latching function for the trip signal TS2 of unbalance stage ∆I
When SGB1/7=0, the trip signal returns to its initial state, i.e. the output
relay drops off, when the measuring signal causing the operation falls
below the starting level.
When SGB1/7=1, the trip signal remains on, i.e. the output relay operated
although the measuring signal falls below the starting level. Then the trip
signal of phase unbalance stage ∆I
and PROGRAM push-buttons simultaneously. (also by signal BS1. Note
switch SGB1/8). When the display is off the signals can also be reset by
pressing only PROGRAM.
SGB1/8 When SGB1/8=1, an external relay reset is performed by input signal
BS1. This makes it possible to have a manual master reset button out-
side the relay. The same button can serve all relays in a station. Another
possibility is to link the reset to some automation.
