Trouble Shooting - HYTROL NBEZ Manual De Instalación Y Mantenimiento

• NBEZ TROUBLE SHOOTING
The following chart list possible problems that may occur in the operation of
an NBEZ conveyor.
*NOTE: The standard application of this model does not have brakes in every
zone. Therefore, zero-pressure accumulation will not necessarily be obtained.
Products will drift into downstream zones when drive is removed from a zone.
TROUBLE
Conveyor will not start or motor
quits frequently
Motor or reducer overheating
Belt doesn't move, but drive
runs
Belt creeps to one side
Product will not accumulate on
one of more zones*
Conveyor not driving
Zone will not "sleep"
Product will not accumulate
from the discharge zone back
CAUSE
1) Motor is overloaded or drawing
too much current
1) Conveyor is overloaded
2) Low votage 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) Conveyor not straight
2) Conveyor not level
3) Material build-up on roller, pulley,
or idlers
1) Cordset disconnected
2) Brake disconnected
3) Zone controller not working
4) Frame not square.
1) Power loss to zone controller
2) Ensure belt is positioned between
tread rollers and pressure rollers
3) Frame not square.
1) "Sleep" feature disabled
2) Upstream zone is blocked or
misaligned
1) No zone stop signal to discharge
zone
SOLUTION
1) Check for overloading of conveyor
2) Check circuit breaker and change if necessary
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
1) Reduce load
2) Use nut on back of center drive to tighten spring take-up to proper tension
shown on indicator
3)Replace drive pulley and tighten belt according to spring take-up indicator
1) Realign bedsections as necessary
2) Correct as necessary
3) Remove residue and install belt cleaners or scrappers if possible
1) Reconnect cable
2) Reconnect cable
3) Replace controller
4) Locate points on corners of section and measure distance diagonally. Use
crossbracing underside to square until dimensions are equal.
1) Check IOP
2) Position belt between tread rollers and pressure rollers and between belt
guides
3) Locate points on corners of section and measure distance diagonally. Use
crossbracing underside to square until dimensions are equal.
1) Set "Sleep" to "Enable"
2) Unblock transducer, align transducer with reflector
1) Check Input cable and signal source
