M3020R Operating Manual

B. Setup Menu

Basically, all settings can be made in the user friendly customer menu. To change certain

parameters during the process, you can change them in the home screen using the key E T. If

an alarm message is displayed on the main screen, it first has to be acknowledged to enable

further parameter change. Adjusting the limit contact for the alarm relay in the setup menu is

only possible if in the "Alarm SP1 enable" is set in the user menu. Same for "Alarm SP2

enable."

The setup menu may be quitt by pressing the (ESC)-key, or, waiting a few seconds with no key

operation. Values can be altered with the (+) and (-)-key, or, depending on the menu, with the

(F3)-key as well.
