7.2 Check Conveyor Belt Elasticity
Check the conveyor belt elasticity by using Sonic Tension Meter. If the elasticity is too loose,
it will affect the motion of the conveyor. The elasticity is measured based on the tension of
conveyor belt. Conveyor belt for different TRI AXI Models will have different elasticity value.
Elasticity specification for TR7600 SIII AXI model is 65 +/- 5N.
Figure 70: Sonic Tension Meter
Steps to perform the conveyor belt elasticity measurement:
1) Move the microphone of Sonic Tension Meter close to conveyor belt.
2) Use finger to tap the conveyor belt.

3) Elasticity value will be display on the Sonic Tension Meter screen.
4) Compare the measured elasticity value with the specification. If elasticity is out of
specification, adjust the conveyor wheel and screw to tighten or loosen the belt.
5) Re-measure the tension. Repeat the above steps until the elasticity is within the
specification.

7.3 Check Conveyor Spring and Lubricate
Check the conveyor spring. Apply grease on conveyor ball screws and then, let conveyor to
run so that the grease will coat on the spring.

Warning: Except for the parts specifically mentioned, the power
MUST be turned off during maintenance. Failure to do so may cause
mechanical or electrical damage.
Besides the daily, weekly, monthly and quarterly maintenance activities, users also need to
perform maintenance activities discussed below during half-yearly maintenance.
8.1 Clean Fans inside Main PC
Clean the dust on the Main PC fans with a compressed air gun.
8.2 Lubricate Clipping Pneumatic Cylinder
Apply grease on the rear and front clipping pneumatic cylinder to lubricate it.
8.3 Change Conveyor Belt
Conveyor belt need to be change during half-yearly maintenance. Steps to change the
conveyor belt are listed below.
1) Remove the board clamp by loosen the screws on the clamp.
