Main switch
Main switch
Start and stop regulating here.
The configuration settings will require that regulating is stopped.
If you try to enter a configuration setting when regulating has started, the controller will
ask if regulating should be stopped.
When all settings have been made and the main switch is set to "ON", the controller will
enable the display of the various measurements. Regulation will start. (One external
main switch must be "ON" before regulation starts.)
Note: In application 1, the main switch automatically follows the main switch of the
AK-PC.
Device config
Mode
Selection of the application mode and how the device is used in application 1.
Note: changing this setting also changes the EKE 1P address, causing communication
with the graphical display to stop. Communication will resume after a power cycle.

AI valve input scale
Configuration of the Analogue Input in application mode 2. If user defined is selected,
the scaling is created via the two parameters, "AI 0% OD" and "AI 100%" OD which
become visible.

Battery alarm
If a battery back-up is connected to EKE 1P terminals, the EKE 1P will close the stepper
motor if the controller loses its supply voltage. The battery voltage must not be
connected from main power supply connected to EKE 1P. A battery voltage lower than
16.5 V will trigger the battery alarm.
The battery back-up may be the Danfoss module (EKE 2U) or a general type (Bat.).

If buttons have not been pressed within a specified period of
time, the screen will return to the overview display. Afterwards,
the user will have to log on again.
If the time is changed, the new time will apply the next time
the user logs in.
If you log out here without waiting for the time-out period
to elapse, go to the overview display and hold down the "X"
button for 3 seconds.
Temperature and Pressure unit
If no buttons have been pushed for a specific period of time,
the light in the display will be minimised.
The light level will be restored upon renewed activity.
Level 1: End user settings, such as changing the main switch
Level 2: Adjusting installer level
This will reset the controller back to default (factory) settings
Here you can see pressure and temperature values received by
the analogue inputs. The values include calibration
Here you can see the status of the digital input function/alarm
Here you can see if the function is on or off
Manual control of relay in application 2. In application 1 the
manual control is done from the AK-PC controller.
Under normal regulation, the function of the relay will be in
"Auto". In the event of an override, the function will be switched
to either "On" or "Off". Remember to switch to "Auto" when the
override is to be completed. Otherwise it will remain in override
until the device is power cycled or reset to factory settings
Define whether the function/alarm will be active with terminals
short-circuited (ON) or open-circuited (OFF)
