ii 920i Multi-Reject In-Motion Checkweighing System Manual

Introduction and System Setup 1
About This Manual
This manual is intended for use by service technicians
responsible for installing and servicing 920i®
in-motion controllers, version 1.10.
Configuration and calibration of the indicator can be
accomplished using serial commands or the indicator
front panel keys. See the 920i Installation Manual,
PN 67887, for more information about configuration
methods.
Some procedures described in this manual
require work inside the indicator enclosure.
These procedures are to be performed by
qualified service personnel only.
Authorized distributors and their
employees can view or download this
manual from the Rice Lake Weighing
Systems distributor site at
www.ricelake.com.
1.0 Introduction and System Setup
This system provides a multiple-reject in-motion checkweighing program for the Rice Lake Weighing
Systems/AP Dataweigh in-motion checkweigher hardware system. It allows for checkweighing of in-motion
products as they cross the belt scale section. The system is capable of storing up to 25 rejected items in its
memory, which is helpful if the reject arm is not located near the scale. This allows time for several rejected
items to reach the reject arm.
The program requires registration to become operational.
1.1 Hardware Requirements
•920i programmable indicator/controller
Note: The scale sample rate MUST be set to 60 Hz. This is
the default setting and should not be changed.

Softkey Description
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.

Calibration 9
3.0 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.
Notes: Calibration is done individually for each product.
A normally closed photo-eye must be used.

Softkey Description
Start Will begin in-motion calibratoin process
Delay Before Sample The amount of time (in milliseconds) after an
item completely passes the photo-eye
before the weight is measured.
This is useful if the photo-eye is mounted
ahead of the belt.
Sample Time Sample duration (in milliseconds)
Note: The Delay Before Sample and Sample Time softkeys
should be used only for fine-tuning after auto calibration. If an
additional auto calibration is performed after these values are
set, they will be reset to zero.

6. To begin auto calibration, press Start.
The item moves past the photo-eye, across the belt, and is auto calibrated.
A graph will be displayed showing the timing of the product weight across the 5 seconds.

7. If there is no End weight sample line or it appears near the 5 second marker, the sample time may be too
long. Try moving the product closer to the photo-eye and performing another auto calibration. If this
does not work, use the Sample Time softkey to reduce the value.
8. If the photo-eye is mounted ahead of the belt, you will need to set a delay before sample value (in
milliseconds).

9. Once the graph displays a distribution curve representing the product entering and leaving the scale,
calibration is successful. See Figure 3-6 on page 11 for an example of an optimal distribution curve.

Calibration 11
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.

Figure 3-6. 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.
