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.
• Normally closed photo-eye
Cards
• Slot 1 - Single A/D card
• Slot 2 - 1 MB memory card
• Slot 3 - 24-channel digital I/O card
Serial Ports
• Port 1 - Printer reports
• Port 2 - Keyboard port (used with iRev)
• Port 3 - Data port (real-time checkweighing
data)
• Port 4 - Not used
1.2 Login
Users must log in to the IMC. The default login name
is "Admin". There is no password until one is
specified by the user. Additional users can be added to
the user database and assigned one of four security
levels. Each increasing level of security includes
