Fig. 31 Adjustment of DIP switch
2.
Ensure that all DIP switches are set to OFF.
3.
Set DIP switches 3 and 8 to ON, see part A.
Ä
This switch-over allows determining the drain interval in a setting range
between 1.5 s and 30 s.
4.
Switch on the voltage.
Fig. 32 Adjustment of potentiometer
5.
Use potentiometer t
on
, which is assigned to DIP switches 1 to 3, to set the
drain interval (temporarily 15 seconds). To do so, turn the potentiometer to
the extreme left.
Ä
The temporary drain interval of 15 s in the set range from 1.5 to 30 s lies
approximately between 5 o’clock and 7 o’clock.
6.
Determine the exact position using a stopwatch, and correct it if necessary.
7.
Set the drain duration (temporarily set to 6 s) with the help of the potentiome-
ter t
off
, which is assigned to DIP switches 6 through 8. To do so, turn the po-
tentiometer to the extreme left.
Ä
The temporary drain duration of 6 s in the set range from 1.5 to 30 s lies
approximately between 2 o’clock and 4 o’clock.
8.
Determine the exact position using a stopwatch, and correct it if necessary.
9.
Switch DIP switch 3 and DIP switch 1 to OFF and ON, respectively, see part B.
Ä
The drain interval is now counted by the switch-over in minutes.
