operation must comply with local regula-
tions and accepted codes of good prac-
tice.

1. Applications
The OD 401 operator display offers an overview of
the system and the possibility of setting various
pump parameters and selecting from various instal-
lation types.
The number of pumps that can be monitored and
controlled depends on the modules in the system.
Note: When the system is started up for the first time
and if the OD 401 has been replaced, the OD 401
program must be loaded from the CU 401 control
unit. The program loading takes a few minutes.
