PRODUCT DESCRIPTION
3.2.5. Versions
The lifting unit is available in the following ver-
sions:
• Single-phase version including switchgear and
shockproof plug
• Three-phase version including switchgear and
CEE plug
3.3. Operating principle
The sewage that arrives is channelled into the
collection reservoir via the inlet pipes, where it
collects.
If the water level rises as far as the switch-on lev-
el then the pump is switched on by the integrated
level control and the collected sewage is pumped
into the connected pressure pipe.
The pump is switched off when the switch-off
level is reached and the set follow-up time has
elapsed.
If the high water level has been reached, an
acoustic and optical warning is given, the forced
switch-on of the pump follows and the col-
lective fault signal is activated. As soon as the
water drops below the high water level, the pump
is switched off once the follow-up time has
elapsed, and the warning message is acknowl-
edged automatically.
