Pump chamber with pump with fitted float switch
The individual pumps are directly controlled by the fitted float switch. After the plug
has been inserted into the socket, the respective pump is now ready for operation in
automatic mode.
Pump chamber with pump, switchgear and separate level control
CAUTION
Malfunction due to incorrect operation of the switchgear!
When the plug is inserted, the switchgear starts in the last operating mode that was
set. In order to be familiar with the operation of the switchgear, the installation and
operating instructions for the switchgear must be read before inserting the plug.
The unit is operated by the switchgear. For information on the operation of the
switchgear and its individual displays, consult the installation and operating instructions
for the switchgear.
Perform a test run before putting the pumping station into operation. A test run checks
the proper functioning and impermeability of the pumping station. It might be neces-
sary to adjust the pump's switching points and follow-up time to guarantee optimum
operation of the pumping station.
