Figure 4-13: A— The Gantry Belt Tensioning tool.

B—The tool in position. (Torque wrench not included.) In this orien-

tation, ignore the bubble-levels on the tool.

C—Plan view of the two posts parallel with the beam at the specified

torque.

6. Attach the Belt Tension Tool as shown above near the greatest

expanse of belt such as at the center of the beam. (There is only

one gantry belt.)

Figure 4-14: Attach the tool to the greatest unsupported expanse of

belt.

7. Turn the wrench keeping the tool level. The two posts on the tool

should be in line (parallel with the beam) when the torque is

reached.

8. If the posts are not in line, contact Data I/O Customer Support or

a local Data I/O approved service representative.

Replacing a PNP Probe Assembly

Technicians trained on the PSV7000 can remove and re-install a Probe

Assembly if it is damaged or malfunctioning.

A spare Probe Assem-

bly comes with the

Self-Service Spares

Kit.

Requirement

• Long metric hex key set (extended reach)

•Spare Probe Assembly

To remove a Probe Assembly

1. End a job and move the PNP head to the TOOL position (click

System > Gantry > Tool) to move it to an accessible position.

2. Properly shut down the PSV7000 System; refer to Shutting Down

the PSV7000 System on page 2-7.

CAUTION: Possible Machine Damage! The PNP head,

Device-position Sensor, and gantry can be damaged by pushing

or pulling it improperly.

• Make sure the AH700 Application is closed.

• Only push or pull the head by gripping the triangular bracket

on the left side of the head.

3. Remove the probe from the target Probe Assembly. See Installing

the Correct Probes in the PSV7000 Operator’s Manual.

4. Disconnect the appropriate air hose form the vacuum generator

on the right side of the PNP head.

Figure 4-15: Probe Assembly #1 (on left) has air hose disconnected

and the Z-axis retention spring removed. Two of the four fasteners are

shown (arrows).

5. Disconnect the four electrical connectors from the Control Board

on the back of the PNP head.

For the 1Home and two Z connectors: push the thumb-tab up to

disconnect the latch.

For the Theta PNP 1: lift the two arms up as shown below.

Figure 4-16: Four Probe Assembly connectors. Detail of THETA PNP1 is

at ‘B.’ All others are style ‘A.’

6. Disconnect and remove the Z-axis retention spring.

7. Remove the four fasteners that hold the Probe Assembly to the

PNP head. Refer to Figure 4-15. (A long 2.5 mm hex key is

required.)

8. Carefully pull the Probe Assembly and air tubing toward the

front of the machine while guiding the cables on the back side

through the small opening.

Reinstalling the Probe Assembly

Generally, the reinstallation is in the reverse order of removal with

these precautions:

• Ensure the ribbon cable fits into the slot on the head bracket and

does not get pinched.

• Make sure the Probe Assembly mates up to the two locating pins

on the head bracket. See figure below.
