NOTE: For additional information about 882IS/882IS Plus and 920i indicators see:
• 183532 882IS and 882IS Plus Intrinsically Safe Indicator/Controller Technical Manual
• 67887 920i Programmable Indicator/Controller Technical Manual
Some procedures described in this document require work inside the indicator enclosure. These procedures must be performed
by qualified service personnel only.
Do not place fingers into slots or possible pinch points.
When working on components inside the enclosure, ensure the power cord is disconnected from the outlet.
IMPORTANT: Use anti-static protection for grounding and to protect components from electrostatic discharge (ESD) when
working inside indicator or fiber optic converter enclosures.
1. Overview
The 882IS/882IS Plus indicator is capable of controlling setpoint batching on a remote Rice Lake Weighing Systems 920i
weight indicator. This capability enables an industrial batching engine to run in a safe environment controlled by the 882IS/
882IS Plus through a fiber optic cable from a hazardous area. With a special iRite program, the 920i is capable of running as a
serial scale with batching setpoints controlled by the 882IS/882IS Plus indicator.
The 882IS/882IS Plus communicates through fiber optic cables connected to a fiber optic converter. The data is then converted
and transfered via serial cable (RS-232 or RS-422) to the 920i. The 882IS/882IS Plus can configure the value of setpoints 1-10,
given the setpoints are enabled on the 920i, for control of both indicator and external equipment functions. The 882IS/882IS
Plus can control a batch operation that has been set up on a 920i (located in the safe area) and supports:
• Batch Start
• Batch Stop
• Batch Pause
• Batch Reset
When setting up a 882IS/882IS Plus with 920i batching systems, the following sections must be followed in order:
