Setup
Before setting up the machine, the user needs to be
familiar with the LCM screens. Refer to Appendix A -
LCM Icon Overview and Appendix B - LCM Run
Screen Overview, starting on page 60.
Perform Startup, page 33, to access the LCM screens.
Piston Position Calibration
The position sensor assigns a numeric value to the loca-
tion of the piston. Higher numbers indicate the piston is
extended and lower numbers indicate the piston is
retracted.
The Piston Position Calibration procedure teaches the
machine the location of the most extended piston posi-
tion ( ), the most retracted piston position ( ),
and the position where the piston engages the pump
cylinder ( ).
Perform the Piston Position Calibration procedure
when first setting up the machine. Also perform this pro-
cedure if the linear position sensor, piston, or any elec-
tronic component has been replaced. Press the Setup
Screen button ( ) to enter the setup screens.
Prepare Machine for Calibration
1. Ensure that both piston shafts are screwed all the
way into the drive block.
2. Navigate to the Position Calibration Screen.
3. Place a waste container under the dispense valve to
capture any dispensed material.
4. Ensure the system air pressure is on by opening the
vented ball valve and the system air pressure regu-
lator shows air pressure in the system.
Retracted Piston Position
5. With air pressure applied to the machine, high light
the Retract Piston button ( ).
6. Press the Dispense Request button ( ). The pis-
ton will fully retract and a number from 1250 to 1600
will be displayed next to the Retract Piston button. If
a number outside of this range is displayed, ensure
the air cylinder air line connections are not switched
and that the linear position sensor is properly
installed.
7. Press the Enter button ( ) to accept the value or
press the Abort/Cancel button ( ) to keep the
previous value.
Extended Piston Position
8. With air pressure applied to the machine, high light
the Extend Piston button ( ).
9. Press the Dispense Request button ( ). The pis-
ton will fully extend and a number 3600-3900 should
be displayed. If a number outside of this range is
displayed, ensure the air cylinder air line connec-
tions are not switched and that the linear position
sensor is installed correctly.
NOTE: If the piston does not extend after pressing the
Dispense Request button ( ) the air pressure may
need to be increased. Use system air pressure regulator
to increase the air pressure in increments of 10 psi until
the piston activates. Material will be dispensed when
adequate pressure is achieved.
