the device status leD is green
Device state
leD possible cause recommended action
green During a dosing, the displayed quantity is
increased or decreased very slowly.
→
Check that the K factor corresponds to the
fitting used.
→
Do a teach-in procedure to determine the K
factor of the fitting used.
→
Check that the flow rate in the pipe is high
enough.
green The dosing does not start although the pro-
cedure has been correctly started:
• Either the dosing quantity times the set K
factor is lower than 6.
→
Set a dosing quantity that is higher or equal to
6 divided by the set K factor.
• Either the pipe diameter is too high for the
dosing of small quantities.
→
Reduce the pipe diameter.
green The display shows that the dosing has started
(the units blink) but the valve connected to
DO2 and/or DO3 does not open.
→
Check the value of the time delay before
opening of the valves.
