Level control

For automatic control of the pumps, a level control device must be installed. To this end, the following signal transmitters can be connected:

• Level sensor
• Change the switching points via the menu.
• Dynamic pressure bell
• Only “IPS” version! Change the switching points via the menu.
• Float switch
• Electrode
• Only Control EC-L1 ... and EC-L2 ...
• Hardware version 2 or higher
• Level monitor

The signal transmitters must be installed according to the system's installation plan. Please observe the following points:

• Float switch: Float switches must be able to move freely in the operating space (pump chamber, tank)!
• Dynamic pressure bell: Install a bubbling-through system to optimally vent the dynamic pressure bell.
• Do not undercut the minimum water level of the pumps!
• Do not exceed the switching frequency of the pumps!
