Switch Function
SGB/1 Switches SGB/1...4 are used for routing an external blocking signal BS to one or more
SGB/2 of the protection stages of the relay module. When the switches all are in position 0
SGB/3 no stage is blocked.
SGB/4
When SGB/1 = 1 the I> stage is blocked by the external control signal BS
When SGB/2 = 1 the I>> stage is blocked by the external control signal BS
When SGB/3 = 1 the I
When SGB/4 = 1 the I
SGB/5 Selection of main settings or second settings with an external control signal BS or via
the serial interface using command V150.
When SGB/5 = 0 the settings can be controlled via the serial port but not via the
external control input BS
When SGB/5 = 1, the settings can be controlled via the external control input. The
main values are enforced when the control input is not energized and the second
settings are enforced when the control input is energized.
Note! When the application includes switching between main and second settings,
it should be noted that switch SGB/5 must have the same position in the main set of
settings and the second set of settings. Otherwise a conflict situation might occur when
the settings are switched by external control or via the serial port.
SGB/6 Latching of the trip signal TS2 of the phase overcurrent unit.
When SGB/6 = 0 the trip signal returns to its initial state (= the output relay drops
off), when the energizing signal causing the operation falls below the set start current.
When SGB/6 = 1 the trip signal is latched (= the output relay remains picked up after
operation), although the energizing signal falls below the start current. The trip signal
is to be manually reset by pushing the push-buttons RESET and PROGRAM
simultaneously.
SGB/7 Latching of the trip signal TS2 of the earth-fault unit.
When SGB/7 = 0 the trip signal returns to its initial state (= the output relay drops
off), when the measuring signal causing the operation falls below the set start current.
When SGB/7 = 1 the trip signal is latched (= the output relay remains picked up after
operation), although the energizing signal falls below the start current. The trip signal
is to be manually reset by pushing the push-buttons RESET and PROGRAM
simultaneously.
SGB/8 Remote resetting of a latched output relay and memorized values.
When the output TS2 has been given the latching mode with switch SGB/6 or SGB/7,
a remote reset can be performed using the external control input BS, when switch
SGB/8 =1.
When the relay is delivered from the factory the
SGB switches are set at zero, i.e. the checksum
for SGB is 0.

From the program versions 037F or 056A
and later versions an additional feature has
been incorporated into the relay module SPCJ
4D29. When the latching function is used
the latched output can be reset by pushing the
PROGRAM button alone, in which case the
stored information of the module is not erased.
