Safety
WARNING:
 Safety glasses are to be worn at all tim es while installing, servicing, operating, or
observing equipm ent. The sudden release of air or fluid can cause dam age to eyes.
Allow only qualified personnel to perform the following task s. Follow the safety
instructions in this document and all other related docum entation.
Relieve s ystem air pressure, m aterial pressure, and disconnect power prior to
servicing Pro−Meter A2K D2K H2K com ponents.
Clean any m aterial that has spilled. Be sure to follow all applicable safety and
environm ental guidelines when cleaning spilled m aterial.
WARNING: An y m aterial injected into flesh can cause severe injury or death. Keep bod y parts
away from m aterial discharge ports. If injection occurs, seek medical attention imm ediately.
WARNING: Operating faulty electrostatic equipm ent is hazardous and can cause electrocution,
fire, or explosion. Mak e resistance check s part of your periodic m aintenance program . If you
receive even a slight electrical shock or notice static spark ing or arcing, shut down all electrical
or electrostatic equipm ent immediately . Do not restart the equipment until the problem has been
identified and corrected.
WARNING: Relieve air and m aterial pressure when equipm ent is not in use for prolonged periods
of tim e. Do not allow pressure to rem ain static when equipm ent is idle as this m ay cause
material to pack and harden.

Lead/Lag Adjustment (A2K and H2K Dispense Systems)
On systems equipped with a lag plate, it is imperative to correctly adjust the lead/lag bolt. Lead/lag
adjustment is needed in instances where there is an extreme difference in viscosity regarding high and low
volume materials. Adjustment of lead/lag optimizes the mix of material.
CAUTION: Ensure the lead/lag bolt is correctly adjusted prior to operating the dispense system. The
carriage can come to rest at hard stop position (A) or home position (B). Adjusting the lead/lag bolt below
the carriage hard stop position can cause severe damage to system components as the carriage will contact
the lead/lag bolt.
Pressure Sensor Calibration
Pressure sensors are individually calibrated and serial numbered at the factory.
CAUTION: If a pressure sensor requires replacement, pressure sensor calibration information has to be
entered into the control panel.
1. Obtain factory serial number from pressure sensor.
NOTE: The serial number is stamped on the pressure sensor.
2. Utilize calibration record as a basis to enter control panel calibration data.
3. Turn control panel OFF.
4. Install new pressure sensor.
5. Connect pressure sensor harness connector to the control panel.
6. Turn control panel ON.
7. Ensure internal meter pressure is at or near zero psi.
8. Log into HMI Control Panel. Refer to HMI Control Panel Login above for HMI Control Panel login
information.
9. Proceed to Pressure Sensor Calibration HMI Control Panel Screen.
10. Enter the 0 psi Cal value and the Full Scale psi value from the calibration sheet.
11. Adjust the Zero Offset until the Scaled Pressure reads zero.
Proximity Switch Calibration (H2K Dispense System)
Calibration of the proximity switch is required to ensure recognition of carriage home position. Refer to the data
captured from the HMI Setup Screens to calibrate the proximity switch. Refer to Recording System
Configuration Data for additional information.

Recording System Configuration Data
CAUTION: It is imperative to record default system settings prior to servicing certain system components. To
prevent component damage and minimize downtime after replacing components, take photos of the HMI Setup
Screens while the equipment is fully operational. The data reflected by the screen shots can be utilized to
restore key system settings. Refer to the HMI Screen Description Manual for an overview of HMI Control Panel
Screens.
Key system data to capture will appear on the following HMI Control Panel Screens:
 Interlock Setup
 Level 1 Setup Menu
 Level 2 Setup Menu
 Meter Setup
 Miscellaneous Pressure Setup
 Position Setup
 Pressure Limits Setup
 Pressure Sensor Calibration
 Purge Setup
 Shot Sequence Setup
 Shot Setup
 System Setup
 Valve Setup
Stroke Adjustment
It may be necessary to adjust the stroke of the inlet and outlet valves. Loosen the stroke adjustment lock nuts
and make fine adjustments to the stroke adjustment bolt until the desired shot pattern is achieved. Refer to the
Customer Product Manual for an illustrative view of the stroke adjustment lock nut and bolt.
CAUTION: Be careful not to fully tighten stroke bolt as this may impact the operation of the valve.
