9.4 Priming the valve:

The valve is shipped with conditioner filled inside valve chamber to ensure the

valve is not run “dry” during initial start-up.

CAUTION: Running the valve dry (without dispense material) may cause

damage to the feed screw and chamber.

1. Attach a barrel of dispensing conditioner (Part number 7305XCON)

to the valve inlet.

2. Apply 8 psi pressure on the barrel and let the pressure push the

conditioner through the valve for 2 minutes. Do not apply more than

10 psi on the conditioner when priming as this may cause compressed

air pockets in the valve chamber.

3. Turn on the motor and let it run until a steady stream of fluid is being

dispensed.

4. Turn off motor.

5. Install appropriate dispense tip to the valve outlet. Do not over

tighten the dispense tip.

Note: Techcon makes available a torque wrench that is designed to

fit Techcon supplied dispense tip. (Part number: 5000-000-080 for

metal valves and 5000-000-082 for Delrin valves)

17. Visually inspect the valve body to any foreign material and repeat

cleaning process if necessary.

18. Insert a 0.1255” pin gauge into the valve body from the motor side.

If the pin moves smoothly and easily through the valve body, there

are no detrimental deposits in the valve. If the pin stop or snags,

gently push the pin through the hole to remove any deposits. If the

pin still does not want to move, please return the valve for repair.

19. Insert a 0.1262” pin gauge to into valve body from the motor side. If

the pin goes through the hole, please return the valve for repair.

9.3 Valve re-assembly

1. Reinstall the female luer lock fitting (10) into the valve body. Make

sure to apply some thread sealant on the fitting, such as Loctite 222.

2. Place the O-ring (8) on the clean out screw (9) and reinstall the clean

out screw assembly into the 45

feed shaft.

3. Lubricate the O-ring (3) with appropriate O-ring grease such as

Parker O-Lube.

4. Install O-ring (3) to the feed screw.

5. Gently slide the motor/feed screw assembly into the valve body

CAUTION: The fit between the feed screw and the chamber is very precise.

Extreme care must be taken during this operation.

6. Reinstall the two socket head screws (6) into the valve body.

Alternately tighten the screws a little at a time until both are secure.

Do not over tighten as this may distort the mounting plate and miss-

align the feed screw.

2. UNPACKING AND INSPECTION

Carefully unpack the valve and examine the items contained in the carton.

These will include:

• Valve Assembly

• Valve bracket

• Sample syringe kit

• Sample Needle Kit

• Cleaning kit

• User guide

3. DESCRIPTION

The TS5000 is a self contained fluid dispensing valve capable of depositing

shots down to 0.008” (0.200mm) in diameter at rates of 5 shots per second.

Fluid can also be accurately dispensed in continuous beads in widths from

0.008” (0.200mm) at rates up to 4” per second. In both cases, dot or bead,

accurate and repeatable dispensing can be accomplished in production by

following the instructions in this manual.

assembly. (Make sure not to tilt the motor during this process.) Turn

the motor off. If the motor/feed screw assembly still cannot easily be

removed, return the valve for repair.

8. Disconnect the motor cable (1) from the controller.

9. The entire feed screw (4) can now be cleaned with a solvent. Use the

brush included the cleaning for this process. Rho-Chem 7642 or a

similar solvent can be used.

CAUTION:

• Do not drop, or exert any forces on the feed screw. This will cause

permanent deflection in the alignment of the feed screw to the

motor shaft

• Do not remove the feed screw from the motor shaft during cleaning.

Doing so will cause misalignment between feed screw and motor

shaft

• Do not submerge motor in solvent

10. Visually inspect the feed screw as closely as possible and make sure

the feed screw is free of all foreign material. Repeat cleaning

operation if necessary

11. Remove the clean out screw (9) and O-ring (8) from valve body (5)

CAUTION: Do not remove the male luer lock fitting and locking hub (12) from the

valve body (5). This is a precisely aligned part. Removal of this part will damage

the valve permanently.

12. Using the brush provided, clean the feed screw chamber with solvent.

13. Using a micrometer to measure the major diameter of the feed screw

threads. If the diameter is measure less than 0.1240”, return the valve

for feed screw replacement.

14. Replace the O-ring (3) on the feed screw (Part number TSD1400-

010B)

15. Using the brush provided, clean the valve body with solvent.

16. Use dry air pressure to blow out passageways.
