5.4.13 Control measurement
For the purposes of a control measurement, a predefined measured volume
of component A and the corresponding volume according to the mixing ratio
of component B are fed separately and dispensed through the spray gun into
measuring cups. The purpose of the control measurement
➤
is to check the mixing ratio,
➤
and to check the metering pumps and metering valves for correct operation.
To perform a control measurement, the unit must be filled with processing
material and vented.
1.
Make sure that all air pressure regulators for the metering pumps have
been fully regulated down and the compressed air shut-off valves are
opend on the metering pumps that deliver the materials used in the current
recipe.
2.
Press the button in the Main menu shown on the left.
3.
Then press the A+B button on the
component selection screen then
displayed.
4.
Adjust the air inlet pressure for
the metering pumps up to
3,0-3,5 bar.
5.
Unlock and operate the spray
gun.
The unit delivers the A component
at first and after a break of about 10
seconds the B component.
The filled volumes are counted up in
the display during the control mea-
surement.
6.
Close and secure the spray gun
again once the filling process is
finished.
7.
Set the air inlet pressure for the
metering pumps right down to
zero.

8.
Wait a few minutes to allow the entrained air to escape from the material in
the measuring cups (particularly with more viscous materials).
9.
Check
➤
whether the volumes indicated match the actual quantities,
➤
whether the quantities of the two components are correct for the mixing
ratio specified in the recipe.
If this is not the case, a volumetric measurement must be performed for the
A- and B-component metering pumps used in the current recipe (see section
5.5.2).
