AUTOMATIC CYCLE
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.
Press the F1 button to access the “General Settings” screen.
The “base impulse count" setting affects the frequency of the
valve sequence.
Example:
If a volume ratio of 3/1 has been selected
(3 parts
A
and 1 part
B
)
and a base impulse of 1 has been inserted, the program will
check the opening of the valves by counting 30 impulses from the
A
flowmeter and 10 impulses from the
B
flowmeter.
The adjustment of the “base impulse count”
must be done in such a way so as to avoid high
frequencies which may not be supported by the
components.
