Operations:
1. Setting the Tension
When rotated clockwise or counter-clockwise, the tensioner nuts move the tensioner plate towards
or away from the inlet outlet ports, placing more or less tension on the chain. Once the desired
tension is obtained, it is important to tighten the nuts against each other to ensure that the tension is
locked. The tension is correct when the chain is taut, but will allow for approximately 1/16”
[1.6mm] of movement (1/8" deflection) when the chain is tugged on by hand. If the discs touch the
bottom of the tube when entering the return path, the tension is too low and needs to be adjusted.
TOO LOOSE
CORRECT
To help with tracking the tension setpoint, a scale is provided next to the tensioning spring so that
the amount of compression applied can be noted. At zero tension (zero compression) the spring
should measure about 6" [15.2 cm].
When adjusting the tension, it is also very important to allow for at least 1.5" [38.1mm] of
clearance between the rotation of the pucks and the back wall of the 180° turnaround unit. It may
be necessary to shorten the chain to obtain this clearance.
Note:
If the tension of the chain is too high it will cause excessive wear on the conveyor
