Safety
WARNING: Allow only qualified personnel to
perform the following tasks. Follow the safety
instructions in this document and all other
related documentation.
SSafety glasses are to be worn at all times while
installing, servicing, operating, or observing
equipment. The sudden release of air or fluid can
cause damage to eyes.
SRelieve system air pressure, material pressure,
and disconnect power prior to servicing
Pro−Meter A2K D2K H2K components.
SClean any material that has spilled. Be sure to
follow all applicable safety and environmental
guidelines when cleaning spilled material.
SAny material injected into flesh can cause severe
injury or death. Keep body parts away from
material discharge ports. If injection occurs, seek
medical attention immediately.
WARNING: Operating faulty electrostatic
equipment is hazardous and can cause
electrocution, fire, or explosion. Make
resistance checks part of your periodic
maintenance program. If you receive even a
slight electrical shock or notice static
sparking or arching, shut down all electrical
or electrostatic equipment immediately.
CAUTION: Relieve air and material pressure
when equipment is not in use for prolonged
periods of time. Do not allow pressure to
remain static when equipment is idle as this
may cause material to pack and harden.

Dispense Mode Descriptions
The dispense command is a signal which instructs
the Pro−Meter A2K D2K H2K to dispense material
based on the mode selected. The Pro−Meter A2K
D2K H2K can dispense material in three distinct
modes (Auto Flow Mode, Manual Flow Mode, and
Manual Shot Mode).
Auto Flow Mode
Auto Flow Mode relies on an external device
(example: robot) to provide all dispense and reload
commands through the machine interlock. The
system will continue to dispense and reload as long
as a signal is received from the external source.
Manual Flow Mode
Manual Flow Mode allows for the continuous
engagement of the dispense command. The system
will continue to dispense as long as the trigger is
engaged. If the trigger is released and depressed
again, system operation resumes from the last
position. There is no automatic reload.
Manual Shot Mode
Manual Shot Mode allows momentary engagement of
the dispense command which completes one
dispense shot and reload as dictated by setup
parameters.
Operation
This section provides a basic overview of how to
initiate a dispense cycle. Refer to HMI Screen
Description Manual for additional information
regarding HMI Control Panel Screens.
Dispense Overview
1. Establish system control parameters. Refer to
Control Parameters for additional information
regarding the setup of system control parameters.
2. Bleed material from Pro−Meter A2K, D2K, H2K.
Refer to Initial Start−Up and Material Bleed
Procedure for material bleed procedure.

indicators both illuminate after selecting the Auto
Startup push button, elect the desired dispense
mode. The Pro−Meter A2K, D2K, H2K is now
ready to dispense. Refer to Dispense Mode
Descriptions for a description of the Auto Shot,
Manual Shot, and Manual Flow dispense modes.
NOTE: Enable Auto Shot,Manual Shot, or Manual
Flow mode by selecting the applicable push button.
Once enabled, the push button will illuminate.
