Water shortage (for “fill” operating mode only)

The level can be measured via the following signal transmitters:

• Level sensor
• Set the switching point in the menu.
• Dynamic pressure bell
• Only “IPS” version! Set the switching point in the menu.
• Separate float switch
• Separate electrode
• Only Control EC-L1 ... and EC-L2 ...
• Hardware version 2 or higher

A forced switch-on of all pumps always takes place in the event of an alarm, irrespective of the selected signal transmitter!

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.
