2. Setting the Tension Switch
To control any undesirable fluctuations in the tension of the system, each 180° turnaround unit is
equipped with a tension limit switch. Any adverse changes in the tension (+ or -) will "trip" the
switch which in-turn cuts power to the conveyor. This allows the operator the opportunity to
examine the tensioning issue prior to damaging the equipment or causing disengagement from the
sprocket.
To set the limit switch, first tension the system the appropriate amount. Once the tension is set,
adjust the placement of the trip brackets so that the roller plunger of the limit switch is centered
between them. The trip brackets should be spaced away from the roller-plunger to allow for some
movement, but not drastic fluctuations. Typically a spacing of about 9/16" [14.3mm] is
recommended between the trip brackets, but individual systems may vary.
If the tension switch trips, investigate to determine the cause and correct the issue prior to restarting
the conveyor. To re-set the switch, the switch must be manual reset by pulling up on the blue reset
knob.
Note:
For maximum life, periodically put a drop or two of lightweight oil on the roller. Specific
application conditions will determine lubricating frequency.
