Installation and operating instructions Wilo-DrainLift XL

35

8.2.1 Switchgear settings

• During the initial commissioning it is necessary to set the unit parameters on the switch-

gear, see also the installation and operating instructions for the switchgear.

• Compare the default value of the motor current with the specifications on the name plate 

of the motor and, if necessary, correct the settings.

• Set the maximum value of the sensor to 1.0  mwc in the menu item “20 mA

d

 level”.

8.2.2 Setting the switching level

The level for switching the pumps and the alarm can be selected as required in steps 
of 1 cm.
Recommended settings:

• Base load ON: 550 mm
• Base load OFF: 80 mm
• Peak load ON: 650 mm
• Peak load OFF: 400 mm
• High water (alarm): 750 mm 

If you wish to use different switching points, you must comply with the supplied filling level 
curve (Fig. 13). The filling level display on the switchgear directly corresponds to the level 
in the tank in this case.
Always note the following points, in particular in case of deviations from the recommended 
settings:

• The filling level probe must be in contact with the base of the tank.
• According to EN 12056-4, the switching volume should be sufficient to allow the volume 

of the discharge piping to be replaced during each pump cycle. 

• The level specifications in the technical data table should be observed (minimum values for 

activation and deactivation level).

• If the pump activation level is set higher than the inlet height, there will be a risk of back-

flow in the connected objects.

• Do not exceed 80 mm for the base load OFF switching point. If additional pumping out is 

required, this must only be done by setting the follow-up time accordingly (see 8.2.3).

• The base load OFF and peak load OFF switching points should be at least 50 mm apart.
