Installation and operating instructions Wilo-DrainLift XS-F 23
6.2 Function
The DrainLift XS-F has a level switch, which switches on the pump according to the water
level. It is switched off automatically after a set time.
The motor winding is protected by an overload safety device which automatically switches
off the pump and switches it on again after it has cooled down.
An integrated, mains-dependent alarm signal (buzzer) signals any operating faults which
occur. An additional potential-free contact (5 A/250 V) on the board can be used to for-
ward the signal.
