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 level 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.
When the high water level is reached, an acoustic warning is out-
put and there is a forced switch-on of all pumps. As soon as the
water drops below the high water level, the pumps are switched
off once the follow-up time has elapsed, and the warning mes-
sage is acknowledged automatically.
3.3.1. Special features of double-pump systems
• An automatic pump alteration occurs after every pump
operation.
• If one pump malfunctions, the other pump is automatically
used as the base-load pump.
• In the event of large volumes of sewage, both pumps can
be switched on in parallel.

Operating modes

3.4.1. Operating mode S3 (intermittent operation)
This operating mode involves the maximum ratio between operat-
ing time and downtime:
S3 10%/120 s
operating time 12 s / downtime 108 s
3.4.2. Variant operating mode
Depending on the volume flow, the operating mode can vary
between S3 10%/120 s and S3 20%/120 s. For more precise infor-
mation, see the table in the appendix of these instructions.
