5.4.4 Mixer settings
In bigger stations a mixing device must be used to keep the pit clean. To install a non clogging mixer
device is recommended.
For the mixing function the controller has two separate forms of controlling the mixing device.
1. Start by level and stop by timer - during filling or emptying of the pit and stopping by a
timer. With this option you might set the function to start during filling phase (before pumping)
or the emptying phase (while pumping). The criteria of the frequency of the mixing is by
setting number of pumpcycles between mixing starts. The stopping of the mixing is made by
setting the running time by a timer.
2. Start and stop by timer – in this option you will set an idle time and a running time for the
mixing device. It will start at the elapsed idle time and keep running for the set operation time.
With this option the mixing will operate independent of the level in the pit. To avoid the
mixing while pumping (important at large flows) there is a function where you can block the
mixer while the pumps are ON.
