ACCURA9/9L INSTRUCTION MANUAL
１General
ACCURA 9/9L maintains shot volumes constantly at any variation of the material balance in the barrel by
means of IEI’s original shot volume control system. The newly incorporated shot-pressure compensation
function can acknowledge the material level in the barrel constantly and compensate the shot pressure
automatically, which solves the former problem of shot-volume variance.
Be sure to read through this instruction manual for correct handling and operation of Accura 9/9L dispenser.

3. FEATURES OF ACUURA 9/9L
This chapter indicates the features of ACCURA 9 as follows. Please refer to the article 7 about
Standard Operation for each function of ACCURA 9/9L.
3.1 Features
ACCURA 9/9L with automatic pressure compensation system has been improved for easier operations and
higher speed than former dispensers. It keeps the shot volume constantly by means of the improvements of
main function such as compensations for level, vacuum and empty alarm system.
Main functions
Function Explanation
Compensation for shot volume Compensate shot pressure automatically in order to
make constant shot volume by not only AUTO mode but
also STEADY mode
.
Compensation for vacuum
Compensate vacuum-level automatically and prevent
bubbling in a barrel and dripping of materials.
Pressure compensation for
viscosity Stabilize shot-volume for materials, which may change its viscosity.
Hardening, softening or mixed with hardening softening
materials are applied.
Empty alarm system Buzzer rings when the material reaches the set level.
Pressure compensation for
cartridge Line coating can be dispensed evenly and constantly by means of pressure compensation when using170cc
cartridge
Communications By RS232 Communication, ACCURA 9 can be
controlled from external host computer.

５Set up before using Accura 9/9L
Please take the following procedures for connections of power source and air piping.
Set-up Procedure
Procedure
1 Connect AC plug with the power source connector on rear
panel.
2 Be sure the power switch is off on front panel before
connecting AC plug with the outlet (100V). Set grounding
definitely.
3 Connect auto-joint with air-import port of rear panel.
Non-lubricated dry air or air filtered through submicron filter or
micromist filter should be used.
4 Connect adapter assembly with air-out-port on front panel.
5 Prepare the barrel for dispensing materials.
Before filling the material into the barrel, clean the barrel and
the needle by airbrushing to take off dust and water.
6 Assemble the needle on the barrel and fill the material into the
barrel up to 70-80%. No bubble should be inside the barrel.
7 Turn on the power switch on front panel.
8 Wipe off the material stuck around 1-2cm from the upper side
of the barrel, and then connect the adapter assembly with the
barrel.
9 Now start.

Exchange barrels
To exchange barrels, press CLR RESET Key.
Dispense-pressure and vacuum-pressure returns to the initial setting figures. Dispensing counter
will be cleared ‘0’. The lapsed time is reset when viscosity-compensation is working.
Dispensing
One shot dispensing is operated with  /OFF key. Level compensation and vacuum compensation works
while Bot-Level and Top-Level are set ‘ON’ on the D.SAMP function setting screen.
Continuous dispensing
Continuous dispensing is operated with SHIFT+  /OFF key. Continuous dispensing keeps on working
until the Sc (dispensing counter) reaches the initial setting at setting Sc (shot counter). Press  /OFF key
in order to stop the continuous dispensing. While not setting the dispensing counter, the continuous
dispensing stops by pressing  /OFF.
Dispense volume fine-adjustment
The dispense volume may increase or decrease slightly when dispense continuously
with a barrel filling with material. Pressing UP key or DOWN key can solve this problem
by changing the shot period to adjust the dispensing volume. This function can be carried out
while other calibrating functions are working in parallel. The fluctuating volume can be allowed
in the setting time ±２０％ except for the following case.
1) If the initial setting dispense time is 0.100 sec or more, it is unavailable to change to
0.099 sec or less.
2) If the initial setting dispense time is less than 0.100 sec., it is unavailable to change the
dispense time short.
3) If the dispense period is over 99.999 sec.
When changing barrels, fine-adjusted dispensing period is reset. If the adjusted dispense period i
sover ±20% or the dispense time is required to adjust soon after changing the barrels, a data
sampling is required by changing the dispense period and pressure.
