Adjustments:
The DURA-SAN belt has an inner cord of many strands that seriously limit stretch. However, over a
period of time some adjustment may be necessary. Caddy Corporation has allowed for this stretch with two
adjusting points. The primary slack adjusting point is under the tail cover. The tail cover is secured by one screw.
After the screw is removed and the cover is lifted off, two pulleys with threaded rods will be obvious. With the
conveyor in the
OFF
position, to increase tension on the belts simply tighten the lock nuts until desired tension is
achieved.
Be careful not to over tighten the belts, the threaded rod should not be moved more than half an inch at one time. If
you require more adjustment than half an inch, there may be another problem. Call the Caddy Corporation Service
Department (856-467-4222 ext. 331) with any questions.
The second slack adjustment point is at the pulleys in the motor compartment. There are two pulleys mounted on
the top of the gear box. These pulleys can be moved up in three steps increasing tension on the belts.
The adjustment at the tail should be maximized prior to moving the pulleys in the motor compartment. When it
becomes necessary to move the adjustment pulleys in the motor compartment, relax the tension adjustment at the
tail, make the adjustment in the motor compartment then reapply tension at the tail, as needed.
Caution: The use of cleaning agents containing ammonia, chlorine or bleach should be avoided.
Lubrication:
There are no grease fittings anywhere on this conveyor. A light oil (3 in 1 oil or sewing machine oil)
may be applied to the pulley bearings periodically. The gear box is sealed and it is seldom necessary to add gear oil.
However, it is a good idea to check the oil level after the first 90 days of operation and then every three months
following. Add oil as needed (Mobile 600 W cylinder oil or any equivalent gear box oil is acceptable).
Caution: Conveyor must in the OFF position for any inspection.
Motor Controls:
Caddy Corporation currently provides a DC motor control (Caddy part number 6235-02). This
controller offers a wide range of selections. We, for the purposes of this manual, will concern ourselves with two,
speed and torque. The speed is regulated through a potentiometer which at it highest setting will run the conveyor at
forty feet per minute. The speed can be reduced to whatever setting is comfortable for your operation.
The current limit (CL/Torque adjustment) CL circuitry, is provided to protect the motor and control against overloads.
The CL also limits the inrush current to a safe level during startup. The CL is factory set to approximately 1.5 times
the full load rating of the motor. The trimpot is preset at the factory but may need to be adjusted, as time goes on,
due to resistance build up.
The
normal Trimpot settings
are as follows, (expressed as a % of full clockwise rotation)
MIN (minimum speed):
0%
MAX (maximum speed):
60%
IR (IR compensation):
15%
CL (current limit/torque):
65%
ACCEL (acceleration start):
50%
