11 CAUSES AND ACTIONS FOR ERRORS AND FAILURES CCW-R-2**B INSTRUCTION MANUAL
11-6
[OVERSCALE ERROR]
/A weight exceeding TW +
UL is detected. 1. Excessive product fed into weigh hopper.
2. Infeed position from the infeeder is one-sided.
3. Position of the infeed control phototube is not
proper.
• This error occurs when weighted
product over “target upper
weight limit” or “set target count +
upper count limit” is supplied to
one head, and when the number of
overscale heads becomes more than
the set value.
If an overscale head exists during
operation, an overscale error will
occur when the operation is
stopped, even if the number of
overscale heads is less than the set
value.
Also for full scale heads (when the
weighted product exceeding the
weight limit is supplied to one
head), an overscale error will occur
when the operation is stopped.
• If overscale is set to be
automatically discharged,
production will not be stopped due
to this error, and a warning message
will be displayed on the lower side
of the screen of the remote control
unit.
However, for full scale heads that
do not discharge products
automatically during operation, an
overscale error will occur when the
operation is stopped.
1. Decrease the feeder amplitude or time
by making feeder adjustment.
2. Adjust the position of the infeeder
(supply chute) so that the infeed
position comes to the center of the
dispersion table.
3. Too many products are pooled in the
dispersion unit because the position of
the infeed control phototube is too high.
Lower the position of the infeed control
phototube.

**ERROR
/STEPPING MOTOR
DRIVE ERROR
Hopper does not open/close
properly.
(**: PH, WH, BH, RS, TH,
and DTH) 1. Product is jammed.
• This error occurs in the event of the
hopper malfunction in cases that
the products are jammed in the
hopper or the motor does not
operate properly due to excessive
load.
1. Remove the jammed products from the
hopper.
2. Inspect for looseness, breakage or loss
of the screws of the hopper. If unable to
repair, contact the distributor or Ishida
customer support to request repair
service.
3. If the error occurs again after the error
is once cleared, check the timing.
If this error still occurs, turn off the
main power switch and turn it on again.
