2.2 Operation of the unit
2.2.1 General
All the functions of the unit, including parameter changes, the selection of a setting
source/calling up the setting and troubleshooting, can be initiated manually using
the keypad.
2.2.2 Parameters 0...4: normal operation
• For NORMAL OPERATION, the parameter number display must be set to a
value between 0 and 4.
• Changes in the signal source (e.g. 2 ⇒ 3) are only implemented after about 5
sec. This delay prevents uncontrolled changes in parameter selection.
