5. OPERATION

5.1 Start Dispensing

The valve is now ready to dispense. Dispensing fluid (via cartridge/syringe

or reservoir) must be connect the supply pressure regulator.

Enter the desired dispensing parameters refer to section 7.5.5 (Rising, Open

Time, Falling, Delay, Needle Lift and Number of Pulses), then touch ‘Save’

icon. Information to the values can be found in the table for ‘essential

parameters’ on the page below.

To start the dispensing, touch the ‘Run’ icon or use external start

signal for both or dot mode. When in line mode start

can only be activate or trigger by an external devised.

Attention: To de-air (removal of air in the system) after going through a

calibration procedure in section 4.3. (e. g. after the change of

cartridge/syringe and/or after the remove of nozzle) use the Purge feature to

de-air. To purge touch and hold the ‘Purge’ icon it will run the

parameter in the current program, and it will run until the purge icon is let

go.

5.2 Parameter Settings for the dispensing process

The essential parameters are:

Parameter

Description

Rise Time

This is the time interval in which the valve is open.

The time increment is in 1 µs starting at 80 µs. The

maximum rising time is 1999 µs.

Open Time

This value defines the time in which the valve is

completely open. The value can be varied in steps of

1 µs. The minimum open time is 1 µs and the

maximum open time is 999999 µs.

Fall Time

During this time, the valve is closing and compressing

the media in the nozzle chamber. The time increment

is in 1 µs starting at 80 µs. The maximum falling

time is 1999 µs.

Delay Time

This is the time between two dispense pulses. It is

adjustable in 1 µs.

Percentage Lift (Lift

of Tappet)

This value corresponds to the stroke of the tappet. It is

entered in percent of the maximum stroke (100%).

Pulses

This value corresponds to the number of tappet stroke

per dispensing cycle in dot mode

Heater OFF

This indicate the heater manifold is Off

Heater ON

This indicate the heater manifold is ON (temperature

range is from 0-90 degree C, click on value next to

icon to adjust setting)

After entering the dispensing parameters, touch ‘Save’ icon to save all the

parameters to the current program location. You can then start your dispensing

process. Note: For more detail on how to enter the dispensing parameters,

refer to section 9.5.3.

6. HEATING

6.1 Introduction

The TS9800 Jet Valve with heating system is available for heating high

viscosity fluid.

The heating system also helps to maintain constant temperature. Required

parts:

• TS9800 Jet Valve with heater

• Heater Cable

6.2 Safety Instructions

• Use the Jet Valve with heating system should only be done by

trained staff.

• Carefully review the material safety data from the dispensing

material.

• Wear adequate protective clothing before starting to dispense

aggressive fluid.

• Be cautious that the media you want to dispense is applicable for

use with a heating system.

Warning:

• When using the Jet Valve with heater, please consult with the

material manufacture for proper operating temperature.

• Be aware of the exposed surface and fittings on the manifold. Do

not touch the heater without protective wear. Failure to do so can

result in serious burn and/or injuries.
