The local control sequence is started by pressing
the push-button
∩
(SELECT). After that the
LED indicator of the object which has been
defined controllable starts flashing.
If the object is closed the indicator for closed
position starts flashing and if the object is open
the indicator for open position starts flashing.
The indicator remains flashing until a control
command is given or a timeout of 10 s has
elapsed.
The closing or opening command is given by
using the I (close) or O (open) push-button.
Depending on the status of inputs 1…3 and
4…13 and the interlocking program logic the
control module executes the selected command
or turns on the INTERLOCK-LED indicating
that the operation is interlocked.
The lenght of the the control output pulse can
be programmed within the range 0.1…100 s.

Function
SG1/1
Switch SG1/1 is used to inhibit interlocking during testing
When SG1/1=0, the interlockings are in use
When SG1/1=1, the interlockings are not in use and the red TEST- LED is lit.
All control operations are allowed.
NOTE! This switch position should be used for testing purposes only!
SG1/2
Switch SG1/2 is not in use and should be in position 0.
The displayed items can be stepped through by
pressing the STEP push-button. The measured
values are indicated by the three green digits at
the extreme right. A yellow LED indicator be-
low the STEP push-button shows, when lit, which
measured value is indicated on the display.
