Selector switches
Additional relay functions required by specified
applications are selected by means of the selector
switches of switchgroup SG1 located on the
Switch
Function
SG1/1
Selection of operation direction for the high-set stage Iϕ>>.
Switch SG1/1 = 0 corresponds to the forward operation direction, i.e. the same
direction as that of the low-set stage Iϕ>.
Switch SG1/1 = 1 corresponds to the reverse operation direction, also see Fig. 4 on
page 8.
SG1/2

SG1/4
Selection of the latching function for the trip signals TS1 and TS2.
When SG1/4 = 0, the trip signals reset to the initial state (= the output relay drops
off), when the energizing signal causing the operation falls below the set start level.
When SG1/4 = 1, the trip signals remain in the activated (= the output relay
operated), although the energizing signal falls below the set start level. The trip signals
can be reset by pressing the push buttons STEP and RESET simultaneously or with
the command V101. When the STEP and RESET push buttons are pushed the
recorded values are erased as well. *)
SG1/5
Selection of setting range for the operate time t> of the low-set stage Iϕ>.
When SG1/5 = 0, the setting range of the operate time t> is 0.1...1.0 s.
When SG1/5 = 1, the setting range of the operate time t> is 1...10 s.
SG1/6
Selection of setting range of the start value of the high-set stage Iϕ>>.
When SG1/6 = 0, the setting range of stage Iϕ>> is 5...40% x I
When SG1/6 = 1, the setting range of stage Iϕ>> is 1...8% x I
SG1/7
Setting of the start value for the residual voltage as a percentage of the rated voltage
SG1/8
of the energizing voltage input.

*) From the program version 068 C and later an additional switchgroup (SG3) has been
incorporated into the relay module. When the latching function is used the latched output can
be reset by pushing the RESET button alone, if SG3/3=1, or by pushing the STEP button alone,
if SG3/2=1, in which case the stored information of the module is not erased.
