4.2 Menu operation
The menu system is a closed system allowing you to scroll both forward and backward through
the individual set-up menus to navigate to the desired setting item. All settings are permanently
stored in an EEPROM and therefore available again even after disconnecting from the supply
voltage. The menu system and the menu items have been designed as simply as possible. Be-
low, each individual menu item is described in detail allowing a straightforward and quick confi-
guration of your device. The structure of the menu system is identical for devices with or without
contacts. The device with contacts deviates from the one without contacts by ten or five addi-
tional menus. These additional menus are marked by a gray background for clear identification.
Please follow the manual meticulously and remember that changes of the adjustable
parameters (switch-on point, switch-off point, etc.) become only effective after pushing
both buttons simultaneously and leaving the menu item.
4.3 Password system
The device is equipped with an access protection to allow access to the complete menu system
only to authorized persons.
• Activating the access protection with the password will lock the complete menu.
• Deactivating the access protection with the password will unlock the complete menu.
The password can be activated and deactivated through menu "PAon" resp. "PAof".
It can be changed according to special menu 4.
In case the password has been lost, there is a possibility to reset the password.
You can do this by loading the defaults via the special menu 3.
4.4 Unit
The unit of the values to be measured is determined on ordering. But it is also possible to
change the unit later by using one of the enclosed unit labels.
