Tolerance Setup
Allows the user to define the output relays that
are used to indicate the 5 zone ranges for each
product check weighed. Also, the out of
tolerance alarm output, out of tolerance alarm
duration, and zone type (by weight or by
percent of target) are set here.
NOTE: When editing the zone type, press Enter
to keep the current value.
Overrun Setup
Allows the user to set up an output to be used
for the overrun alarm, as well as the alarm
duration (in milliseconds). Setting the alarm
duration to 0 will disable this feature. If an
overrun is detected, the overrun alarm will
signal the error, but the system will attempt to
continue weighing.
Infeed Setup
Allows the user to slow down the infeed
conveyor (the part of the conveyor before the
scale section) by having it turn on and off for
specified times. This feature can be used for
spacing products as they approach the scale
section of the conveyor. If products are too
close together, set the “on time” and “off time”
(in milliseconds) to have the infeed conveyor
turn itself on and off for the specified amount of
time. For example, one product will enter the
scale, the infeed conveyor will stop briefly while
the scale section continues to run, then the
infeed conveyor will resume and the next
product enters the scale, etc. Set the “on time”
and “off time” values to 0 (which is its default) to
disable this feature if there is enough space
between products for the infeed conveyor to
run constantly.

getting an accurate weighment (i.e., due to
water dripping on scale, sawdust
accumulation, etc.), use this feature to zero the

Calibration
Calibrating a product allows the user to select and
actually run a sample product across the scale and
allow the user to see the distribution curve and setup
the weighing parameters for each product. These
parameters include sample delay and sample time.
By pressing Start , the conveyor will begin and the
photo-eye will detect a product. At the end of 5
seconds, the system will alert the user to the time at
which the detection input was cleared. A graph will be
displayed showing the timing of the product weight
across the 5 seconds. The user can then set the delay
before sampling time and sample duration by viewing
the graph weight and product detection details.

3.2
Making Adjustments for an Optimal Graph
Ideally, the distribution curve should be symmetrical. You should be able to see an arc as the item enters the belt
and an arc as it leaves.Figure 3-4 and Figure 3-5 on page 10 show an arc as the product enters the belt, but not the
full arc as the product leaves. While this will still work, it leaves little room for unexpected variables; since
weighment is being measured until the product is almost off the belt, it is more likely that an inaccurate
weighment could be made. Having the weight taken at the center of the distribution curve is preferred. See
Figure 3-6 for an example of an optimal distribution curve.

To achieve an optimal graph, fine-tuning of the delay before sample and/or sample time may be necessary. Once
one of these values is set, the graph will refresh with the latest auto calibration shown under the new parameters.
Do not perform another auto calibration or it will reset any fine-tuning back to zero. Simply use the latest auto
calibration and fine-tune, repeatedly if needed, until the graph is displayed as desired.
