Functions
Funct. empty (LL input)
The “LL" input is designed as a level transmitter input for the “EMPTY“ level of the dosing
medium container.
Program the desired effect of the contact, the delay and the alarm function.
If the input is active after the test time “Delay“, an error message occurs.
If you have activated “Alarm” but no draining function, the output AL switches in addition to
the error message.
Desalination monitoring (FC input)
The “FC" input is designed to monitor the desalination valve.
Program the desired effect of the contact, the test time and the alarm function.
The desired effect relates to an active flow controller (for flow through).

Output AL/EV (“draining” function)
Program the function EV to activate the “Draining” function:
The input valve is closed and the desalination valve opened for the programmed period at
the start time (time) on the respective weekday or daily. This drains the system. The
message “Draining” and the remaining time appear on the display.
The desalination valve closes, the input valve opens and the system is filled after the
draining period. After a set filling time of one hour, the desalination lock is released.
