TROUBLESHOOTING GUIDE (CONTINUED)
SYMPTOM
CAUSE
CORRECTION
The machine stops and the film is
broken. (the film breaks when the
Dancer Roller is pulled against the
machine frame.)
The Film Unwind Assist
has developed a problem.
The Film Clamp may need adjustment for
clearance or the Cylinder may not be engaging.
Check the Unwind Assist Cylinder for proper
operation of the Dancer Arm. The Film Roll
Holder Brake Cylinder may not be releasing,
not allowing the film roll to unwind. The
Dancer Spring tension may need to be
increased, by moving the Spring Bracket.
The machine stops and the film has
not indexed far enough. The Eye
Mark did not pass the Photo Eye
and no side seal was formed.
The film advanced too
slowly causing the Eye
Mark to time out because
of excess friction between
the Belts and the Fill
Opening.
Locate the cause of the friction: Is the water to
the Felt Lubricator functioning properly? Is
the Film Feed Belt pressure too tight? Is the
Film Feed Belt tension tight enough?
In the Auto mode, the machine
stops and the film has indexed too
far without forming a side seal.
The Eye Mark passes the
Photo Eye, but the Photo
Eye did not see it.
Locate the reason that the Photo Eye did not
see the Eye Mark: Does the film have an Eye
Mark printed on it? Is the film threaded
between the Photo Eye and the Reflector? Is
the Eye Mark passing above or below the
Photo Eye Beam rather than through it? Is the
Photo Eye Sensitivity set correctly for the Eye
Mark being used?
In the Auto Mode, the film will not
advance (the volumetric drum is
turning).
Required inputs are not
activating.
Check for inputs from the side seal limit
switch (must open and close with each cycle),
air pressure switch and volumetric drum limit
switch (should open and close when tripped by
the cam).
Volumetric dumps more than once
on the single dump setting (double
dump)
Input from side seal
switch is out of time with
the volumetric Prox
switch.
Sticking or slow clutch air
valve.
Excessive speed of drum
rotation.
Increase the side seal speed with flow control.
Replace the flow control or valve.
Lubricate, clean, or replace the valve.
Reduce the drum speed, maximum soeed is
approx. 40 (dumps) bags per minute.
Volumetric dumps more times than
selected on the four position
switch. The switch is set on two or
more dumps.
Sticking or slow clutch air
valve.
Adjust Prox or
Lubricate, clean, or replace the valve.
Replace Prox.
Volumetric does not dump the
amount selected on the four
position switch.
Adjust Prox or
Replace Prox
