Activating/deactivating service
mode
Additional settings can be made in service mode. The mode is acti-
vated or deactivated as follows.
Caution - material damage!
Improper setting changes can lead to pump operation errors, which
can lead to material damage to the pump or system.
• Settings in service mode should only be made during commission-
ing and only by qualified personnel.
• Set DIP switch 1 to the ON position.
Service mode is activated. The symbol shown here flashes on the sta-
tus page.
The sub-elements of menu 5.0.0.0 switch from the “Information”
element type to the “Selection/setting” element type, and the stand-
ard “access disable” symbol (see symbol) is hidden for the respective
elements (except for <5.3.1.0>).
The values and settings for these elements can now be edited.

The current state of the disable is represented on the symbol display
by the symbols shown here.
• To confirm the change, press the red button.
The new setpoint will be accepted and the display will return to the
status page.
Disable active

all menu elements remains as it was.

<1.0.0.0>, <2.0.0.0> and <3.0.0.0>).
NOTE
To edit the sub-elements of menu <5.0.0.0>, service mode must also
be activated.
• Reset DIP switch 2 to the OFF position.
The display returns to the status page.

Errors can be acknowledged after a waiting period despite the “access
disable” being active.
