b. Place a waste container below the ratio check
valves. The next steps will cause the machine to
dispense material.
c. Press then . The pump will travel to
bottom-most position.
d. After the pump stops moving, press then
press . The pump will travel to the top-most
position.
NOTE: During this process, the system learned the
mechanical limits of piston travel. If the pump did not
reach either piston mechanical travel limit for any rea-
son, repeat the procedure.
21. Press to exit the Setup screens.
22. Press repeatedly to select Operator mode
then press to accept.
23. Press to enter the Setup screens then press
left or right to navigate to the main Calibration
screen.
Flow Meter / No Flow Meter Calibration
24. If flow meters are installed, refer to Flow Meter or
Flow/Ratio Calibration starting on page 39. If flow
meters are not installed, refer to No Flow Meter
Machine Calibration starting on page 40.
Flow Rate and Ratio Learning
25. At the main Calibration screen, press to erase
all learned data.
NOTE: This will not affect the weight calibration that was
just completed.
26. Press to exit the Setup screens.
27. Press repeatedly to select Shot mode then
press to accept.
28. Select a defined shot that will provide a 10 second
or longer dispense at the flow rate and ratio
intended to be used during normal system opera-
tion.
NOTE: If the ambient temperature is significantly below
68°F (20°C) then the flow rate for the machine will need
to be decreased. For most materials at 68°F (20°C) at a
2:1 to 3:1 ratio, a maximum flow rate of 335 g/s or 335
cc/s can be expected. The machine should not be oper-
ated much below 120 g/s or 120 cc/s at a 2:1 to 3:1 ratio.
