Dosing error
The mixing ratio differs
from the set value (the
actual mixing ratio is
displayed).
Check:
5
Is there enough material in the containers?
5
Is the mixing unit clogged? Switch the system to flushing
operation and check whether flushing agent is delivered to
both the A component side and the B component side in
alternating flushing. Should the flushing agent for one of the
components not be pumped, this side of the mixing unit is
clogged and needs to be cleaned.
5
Is the metering valve of the B component permanently
opened and is it no longer cycling or only cycling very slowly
and irregularly, before the system shuts down?
In this case the stroke limiter for the metering valve is incor-
rectly adjusted and needs readjusting.
5
Are the return ball valves on the mixing unit fully closed?
5
Are the ball valves in the suction system open (if present)?
The unit must be flushed to remove the incorrectly
mixed material from the unit before spraying operations
can be restarted.
Upw.stroke A t.fast,
Upw.stroke B t.fast
The metering pump
selected in accordance
with the current recipe for
the A side or the B side
is executing an up stroke
too quickly.
Check for the metering pump on the A side or the B side:
5
Is there enough material in the container?
5
Are the return ball valves on the mixing unit fully closed?
5
Has the metering pump been fully vented? Allow the material
to circulate slowly to vent the metering pump.
5
Is the sensor in the metering pump air motor loose?
This can be the case if the fault appears immediately
(< 1 second) after the switch over to spraying mode. Check
whether the sensor is firmly seated in the downwards stroke
of the material pump. The sensor will have to cemented
back in if it can easily be moved and the LED lights up and
goes out.
5
Is the piston valve of the metering pump closing correctly?
Clean ball and valve in the double piston, replace ball and
valve seat as necessary.

5
Is the bottom valve of the metering pump closing correctly?
Unscrew the bottom valve and thoroughly clean ball and
seat if necessary.
