Blocking or control
input switchgroup
SGB
Switch Function
SGB/1...4 Switches SGB/1...4 are used when the external control signal BS is to be used for
blocking one or more of the current stages of the module. When all the switches
are in position 0 no stage is blocked.
When SGB/1 = 1, the stage I> is blocked by the input signal BS
When SGB/2 = 1, the stage I>> is blocked by the input signal BS
When SGB/3 = 1, the stage I
When SGB/4 = 1, the stage I
SGB/5 This switch enables switching over from the main settings to the second settings
and vice versa even without serial communication, using the external control in-
put signal BS.
When SGB/5 = 0, the settings are not to be remotely controlled or they are con-
trolled via the serial communication only
When SGB/5 = 1, the settings are remotely controlled or via the external input.
Main values of the settings are used when there is no control voltage on the input
and the second settings are enforced when a control voltage is connected to the
control input.
Note!
Whenever main and second settings are used, care should be taken that the switch
SGB/5 has the same position both in the main and second setting bank. Other-
wise a conflict situation might occur when switching setting banks by contact or
via serial communication.
SGB/6 Selection of a latching feature for the tripping signal TS2 for overcurrent faults.
When SGB/6 = 0, the tripping signal returns to its initial state (= the output relay
drops off ), when the measuring signal causing the operation falls below the start-
ing level.
When SGB/6 = 1, the tripping signal remains on (= the output relay operated),
although the measuring signal falls below the starting level. Then the starting
signals have to be reset by pressing the push-buttons RESET and PROGRAM
simultaneously.
SGB/7 Selection of a latching feature for the trip signal TS2 for earth faults.
When SGB/7 = 0, the tripping signal returns to its initial state (= the output relay
drops off ), when the measuring signal causing the operation falls below the start-
ing level.
When SGB/7 = 1, the tripping signal remains on (= the output relay operated),
although the measuring signal falls below the starting level. Then the starting
signals have to be reset by pressing the push-buttons RESET and PROGRAM
simultaneously.
SGB/8 Remote resetting of a latched output relay.
When the output relay with SGB/6 or SGB/7 has been selected to be latching,
a remote relay reset can be performed using the control input signal BS when
SGB/8 =1.
When delivered from factor all switches SGB are set at zero, i.e. the checksum
SGB is 0.

From the program version 042D and later
versions an additional feature has been incor-
porated into the relay module SPCJ 4D24.

When the latching function is used the latched
output can be reset by pushing the PROGRAM
button alone, in which case the stored informa-
tion of the module is not erased.
