Operation with operator unit

2.2.1

Operator unit functions

The operator unit is used to make all settings and readouts required for operating
the RMB795B central control unit.
All entries made on the operator unit are transmitted to the central control unit
where they are handled and stored. The operator unit itself does not store any
data. The information for the user is generated by the central control unit and
forwarded to the operator unit where it is displayed.
2.2.2

Operating concept

All setting and readout values are arranged as data points (operating lines) in a
software menu tree. Using the operating elements, any data point can be selected
and read or set. The LCD shows all menus in plain text..
The central control unit has several languages loaded. Enter the relevant language
during commissioning. The Operating Instructions for the end user are included
with the central control unit; they contain the languages with which the unit is
supplied.
