Mix Pressure Tolerance
The pressure of one component must be within
a percentage (±) of the pressure of the other
component during spray or mix. Set the desired Mix
Pressure Tolerance in this field. The default is 75%.
Mix Idle Timeout
The air flow switch (AFS) detects air flow to the gun
and signals that the gun is triggered. If you are not
using an air flow switch, the system does not know if
the gun is spraying. If a pump failed you could spray
pure resin or catalyst without knowing. This should
be caught by the Mix No Flow Timeout; the default
is 5 seconds. The Mix Idle Timeout will trigger Idle
mode, which will run a pump stall test to check for
leaks, then put the pumps in Standby (holding their
current position) after the designated period of time.
Enter the desired Mix Idle Timeout in this field.
See Air Flow Switch (AFS) Function, page
Mix No Flow Timeout
The air flow switch (AFS) detects air flow to the gun
and signals that the gun is triggered. If the air flow
switch indicates that the gun is triggered, but there is
no fluid flow through a pump, you could spray pure
resin or catalyst without knowing. The Mix No Flow
Timeout will cause the system to shutdown after the
designated period of time. The default is 5 seconds.
Enter the desired shutdown time in this field.
