After the adjustment is done, the change-over switch „output can be used to check the connection to
i
the control unit even when the container is empty. If you invert the signal when the container is empty
(switch from right to the left), the control unit has to show that the container is full.

Time delay

The option „time delay" allows to smoothing of the level fluctuations. The higher the timedelay level the
greater the delay of the output signal.
Potentiometer left max. position = no delay of the output signal.
Potentiometer right max. position = max. delay of the output signal.
i
The potentiometers do not have a mechanical end stop. The minimum or maximum is achieved
with 20 turns.
Extra relay
- If the adjustment has been carried out correctly, when the container is filled and the reference range is
covered, the lowest green LED will switch on and the relay „SIGNAL ALARM" will be activated.
- If there is a power failure or the filling level falls below the reference range, the relay „Signal Alarm" will be
released.
- The relay can also be used as a wire break monitoring or a low level protection.
Change-over switch „output" in right position
increasing output signal
container empty = output signal min.
container full = output signal max.
Change-over switch „output" in left position
output signal decreasing
container empty = output signal max.
container full = output signal min.
