9.5 Submersible pumps

The control units KLcontrol.M can work together with 230 V submersible pumps. These can be
used either in lieu of pneumatic lifters or for an additional transport process (e.g. from a second-
ary buffer tank).
NOTE
A total current of 10 A is provided for the outputs. Make sure that this total current cannot be ex-
ceeded.
9. Additional controller functions
Select "UV module" in the module's submenu.
This presents the control unit's outputs addressed via the UV
module.
T-step with which the UV module is to start. In principle, all
steps from T1 to T22 are possible here. We recommend start-
ing with clear water extraction T13.
The runtime is set here. Possible are 0–99 min.
You can select here the input for a float switch that enables
the module to operate in level dependent mode.
This lets you activate an operating hours countdown. UV
emitters are prone to wear. The UV emitters have a service
life of 1500 h, after which they must be replaced. When the
entered number of operating hours has been reached, the
message H.4 "UV operating hours" appears.
Select "0 h" to deactivate monitoring.
After the emitter's replacement, the counter can be reset.
