ENGLISH
Light-emitting diodes (LED) on front panel
There are LED’s on the front panel which will light up when the
corresponding relay is activated.
The upper LED will indicate the valve’s opening degree. A short
pulse indicates a slow liquid flow and a long pulse a fast liquid
flow.
The three lowest LED’s will flash, if there is an error in the regula-
tion.
In this situation you can upload the error code on the display and
cancel the alarm by giving the uppermost button a brief push.
Display
The values will be shown with three digits, and
after an opera-
tion the controller will return to its standard mode and show the
measured liquid level.
Operation
The buttons
When you want to change a setting, the two buttons will give you
a higher or lower value depending on the button you are push-
ing. But before you change the value, you must have access to the
menu. You obtain this by pushing the upper button for a couple
of seconds - you will then enter the column with parameter codes.
Find the parameter code you want to change and push the two
buttons simultaneously. When you have changed the value, save
the new value by once more pushing the two buttons simultane-
ously.

Gives access to changes
Saves a change
Examples of operations
Set reference
1. Push the two buttons simultaneously
2. Push one of the buttons and select the new value
3. Push both buttons again to conclude the setting
Set one of the other menus
1. Push the upper button until a parameter is shown
2. Push one of the buttons and find the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting

The level alarm is linked to:
0: Rising level (higher level than A16)
1: Falling level (lower level than A16)
2: Same function as if A18=0. When A2 alarm is gener-
ated and Relay for lower level limit, gives OFF signal
(cut out).
3: Same function as if A18=1 When A2 alarm is gener-
ated and Relay for lower level limit, gives OFF signal
(cut out).
