You can secure the low-level switch by entering a delay of 0-9999 seconds. Also, it is possible to
indicate whether the unit must be switched off when the level in the dosing tank is too low. When the
unit is turned off, you can have the unit turn on automatically when the dosing tank is filled up to a
sufficient level.
Level measurements 0(4)-20mA output
If level measuring with power output is active, the “0-20mA Interface” will be selected.
It will subsequently be possible to select a 0-20mA input. And after that, it will be possible to select the
range of the measurement cell (0-20mA or 4-20mA).
As far as level measuring is concerned, the percentage with empty dosage tank and the percentage
with full dosage tank can be specified.
Also, it is possible to indicate whether the unit must be switched off when the level in the dosing tank
is too low. When the unit is turned off, you can have the unit turn on automatically when the dosing
tank is filled up to a sufficient level.
