Operation
The operation within the configuration menu is triggered by an external switching contact.
In order to access the configuration menu the contact must be pressed for more than 10
seconds.
Following actions can be triggered by pressing the contact:
Short pressing the contact (less than 2 seconds)
•
The cursor moves to the next line.
•
If the cursor is in the bottom line and another menu item exists, that menu item is
displayed in the bottom line.
•
If the cursor is on the last available menu item, it jumps back to the top line
Long pressing the contact (more than 2 seconds)
•
If the cursor is in the top line, it returns to the next higher menu or leaves the
configuration
•
If the cursor is not in the top line, the selected menu is opened or the configura-
tion is selected/changed
After closing the configuration menu all changes are automatically stored and remain even
after turning off the system.
Do not interrupt the power supply with active configuration menu, since the
configuration is not completely stored at voltage interruption.
