Decommissioning
The unit is decommissioned in reverse order of setting up.
4.3
Operation
Operation of the dosing control unit is based on the control signals from the master control
unit applied at plug 1. The dosing quantity depends on the connected dispenser.
NOTE
The quantity of medium that has been drawn in by the suck-back may only be large
enough to prevent dripping.
If more is sucked in, air gets into the dispenser and the medium is dispensed with a delay
at the next dosing.
If the suck-back is set higher than the dosing, the dispenser may be damaged by dry
running.
