Selector switches
The software switchgroups SGF1 and SGF2 are
used for selecting additional functions required
for different applications. The switch numbers,
1…8, and the position of the switches, 0 or 1,
are shown on the display, when the switches are
being set using the push-buttons on the front
panel. Normally only the checksums of the
switchgroups are displayed. These can be found
in the main menu of the regulating module, see
chapter "Menu chart". The tables below also
show the default settings of the switches and
the corresponding checksums.
Switch
Function
Default
SGF1/1
External control input connection
0
When SGF1/1=1, the raise’ input is connected as parallel control input
When SGF1/1=0, the raise’ input is connected as raise control input
SGF1/2
Selection of parallel operation principle
0
When SGF1/2=1, the negative reactance principle is used
When SGF1/2=0, the minimizing circulating current or the master/slave
principle is used
SGF1/3
External control input connection
0
When SGF1/3=1, the blocking input is connected as remote/local
control input. The regulator is controlled remotely when the external
control input is energized and controlled locally when it is not energized.
When SGF1/3=0, the blocking input is connected as blocking input.
The automatic and manual voltage regulation is blocked when the
external control input is energized.
SGF1/4
Display mode
0
When SGF1/4=1, the measured voltage U
m
will be displayed continu-
ously when 5 minutes have passed from the latest front panel operation
When SGF1/4=0, the display turns dark when 5 minutes have passed
from the latest front panel operation
SGF1/5
Selection of inverse/definite time
1
When SGF1/5=1, the inverse time characteristic is in use
When SGF1/5=0, the definite time characteristic is in use
SGF1/6
Main/second setting bank during parallel operation
0
When SGF1/6=1, the main setting bank is used in single operation and
the second setting bank in parallel operation. Parameter V150 and the
setting value in submenu 4 of register A are disabled.
Note! To become active, the switch must be set in both setting banks.
When SGF1/6=0, the main and second setting banks are controlled by
the parameter V150 and the setting value in submenu 4 of register A
