Operation - Danfoss EKC 319A Anleitung

Operation

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 discharge temperature.
Light-emitting diodes (LED) on front panel
There are LED's on the front panel which will light up when the
belonging function 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 lowermost LED's will flash, if there is an error in the regu-
lation.
In this situation you can upload the error code on the display and
cancel the alarm by giving the uppermost button a brief push.
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.

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
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you reconnect the supply voltage
