AUTOMATIC MODE
The automatic cycle is used for regular working functionality.
In order to activate automatic mode functionality, the operator
must turn the selector(
J1
) to the automatic position.
The tapping cycle can be activated while the selector is in the
manual position. In order to activate it, set the
"Enable tapping
cycle"
value to
"1"
and set the Number of control cycles field to
the
"number of tapping cycles"
to be performed.
Once these values have been set, just turn the selector to the
automatic position and then back to the manual position. The
machine will perform the number of cycles requested.
To deactivate automatic mode functionality, just turn the selector
(
J1
) to the manual position.
When the automatic cycle is active, the program controls the
sequence of the valves for the two components and doses them
based on the requested ratio and based on the
“impulse count
frequency”
settings.
Just press the
F1
button to access the
“General Settings”
screen.
The adjustment of the “impulse count frequency”
must be done in such a way so as to avoid high
frequencies which may not be supported by the
components.
TOTAL SHUTDOWN OF THE CONTROL PANEL
The system shutdown procedure requires the main switch (
J2
)
to be turned to the
"O"
position.
This operation completely arrests all of the system’s functionalities.
The
“impulse count frequency"
setting affects the frequency
of the valve sequence.
Example:
Let us suppose we are selecting a volume ratio of 3/1
(3 parts
A
and 1 part
B
)
and setting a pulse frequency of 1. The programme
will control the valve opening, counting 30 pulses of the
A
supply
measurer and 10 pulses of the
B
supply measurer.
If a pulse frequency of 2 were set, the machine would count 60
pulses of
A
and 20 pulses of
B
.
