THREADING THE BELT
Step 1
The most important item in threading NBC belts is to turn the system air ON with NO
POWER to the logic modules. This will depress the pressure pans and open up a belt
path. Without air, all the rollers are engaged as NBC is a spring-to-drive system and it will
be extremely difficult to thread the belt.
NOTE – Use the slide switch located at the take-up cylinder base to turn the air take-
up OFF.
Step 2
Disconnect the power to ALL the logic modules (switch off SICK conveyor mounted power
supplies). All logic modules lights should be OFF. This will depress the springs in the
pressure plan creating a belt path.
Air pressure
should be set
between 30 to
40 PSI
