Drive Chain Alignment And Tension; Trouble Shooting - HYTROL ABEZ Manual De Instalación Y Mantenimiento

• Drive Chain Alignment and Tension

The drive chain and sprockets should be checked periodically for proper
tension and alignment. Improper adjustment will cause extensive wear to
the drive components.
TO MAKE ADJUSTMENTS
1. Remove chain guard.
2. Check sprocket alignment by placing a straightedge across the face of
both sprockets (Figure 9B).
3. Loosen set screws and adjust as needed. Re-tighten set screws.
4. To adjust chain tension, loosen bolts that fasten motor base to mount-
ing angles, both sides of the conveyor. Tighten take-up bolts until desired
chain tension is reached. (Figures 9A). Re-tighten mounting bolts.
5. Lubricate chain per lubrication instructions.
6. Replace chain guard so that it does not interfere with drive.

CAUTION! Never remove chain guards while the conveyor is
running. Always replace guards after adjustments are made.

TROUBLE SHOOTING:

TROUBLE
Conveyor will not start or motor
quits frequently.
Drive chain and sprockets wear
excessively.
Loud popping or grinding noise
in bearing.
Motor or reducer overheating.
Belt doesn't move, but drive
runs.
Belt creeps to one side at tail
pulley.
Entire belt creeps to one side.
Product will not accumulate on
one or more zones.
No zone will accumulate.
Conveyor becomes live-roller.
Zone will not drive.
Zone will not "sleep".

The following chart list possible problems that may occur in the operation of the conveyor.
CAUSE
1) Motor is overloaded or drawing too much current.
1) Lack of lubrication on chain causing chain stretch
which creates improper chain to sprocket mesh.
2) Sprockets are out of alignment.
3) Improper chain tension.
1) Defective bearing.
2) Loose set screw.
3) Loose Drive Chain
1) Conveyor is overloaded.
2) Low voltage to motor.
3) Low lubricant level in reducer.
1) Conveyor is Overloaded.
2) Belt is too loose.
3) Lagging on drive pulley is worn.
1) Tail pulley, return idler, or snub idler near tail pul-
ley not properly aligned or square bed .
1) Conveyor not straight.
2) Conveyor not level.
3) Material build-up on roller, pulleys, or idlers.
1) Air line is kinked.
2) Cordset disconnected.
3) Solenoid cable disconnected.
4) Solenoid valve not working.
5) Zone Controller not working.
1) Power loss to Zone Controllers.
2) Air loss to entire conveyor.
1) Controller lens dirty.
2) Reflector missing or damaged.
1) "Sleep" feature disabled.
2) Upstream zone is blocked.

SOLUTION
1) Check for overloading of conveyor.
2) Check heater or circuit breaker and change if necessary.
1) Replace chain and sprockets. Provide adequate lubrication.
2) Align sprockets. (See "Drive Chain Alignment and Tension").
3) See "Drive Chain Alignment and Tension".
1) Replace bearing.
2) Tighten set screw.
3) Tighten Chain.
1) Check capacity of conveyor and reduce load to recommended level.
2) Have electrician check and correct as necessary.
3) Relubricate per manufacturer's recommendations. For HYTROL
reducer, refer to separate manual.
1) Reduce load.
2) Use belt take-up to tighten belt.
3) Replace the drive pulley lagging and tighten belt.
1) Adjust as necessary. See "Belt Tracking" pre-tracking inspection in
this manual on how to square tail pulley, snub idler, and return idler.
1) Re-align bed sections as necessary.
2) Correct as necessary.
3) Remove residue and install belt cleaners or scrappers if possible.
1) Unlink air line.
2) Reconnect cable.
3) Reconnect cable.
4) Repair/replace solenoid valve.
5) Replace controller.
1) Check power supply.
2) Check air supply.
1) Clean lens.
2) Replace reflector.
1) Set "Sleep" to "Enable".
2) Unblock Zone.
