5.1.2 Detailed description of the operational principle
The detailed description will guide you through the menu step by step.
Connect the unit to the power supply and wait for the startup procedure to complete. At first the software version im-
plemented on the unit will be displayed for a brief period. The unit will then switch directly into measured value dis-
play.
Pressing the button will take you from display mode to the main menu. (The control will continue running whilst in
menu mode.)
Use these buttons to navigate the main menu.
After confirming a main menu item the associated submenu will open
Here you can configure operating parameters:
Cycle through the submenu to configure the parameters,
then confirm the menu item to be changed.
You can now set values within specific limits.
After confirming the value the system will save it. This will automatically return you to the submenu.
If no button is pushed for approx. 5 s, the unit will automatically return to the submenu. Changes to values will not be
saved.
The same applies to the sub- and main menu. The system will automatically return to display mode without saving
the (last) value changed. Parameters which were previously changed and saved will be retained and not reset.
NOTICE! After saving values with the Enter key they will be applied to the control.
E To exit the main or submenu, select menu item E (Exit).
