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

Connecting Fiber Optic Cable to 882IS/882IS Plus and Fiber Optic Converter

WARNING: Disconnect indicator and fiber optic to serial converter box from power sources before opening.
IMPORTANT: Use anti-static protection for grounding and to protect components from electrostatic discharge (ESD) when working inside the fiber optic converter enclosure.

The fiber optic to serial converter box is equipped with a duplex fiber optic port for communicating with a 920i indicator located in the safe area. It provides electrical isolation and eliminates the use of IO barriers commonly used in intrinsically safe systems.
Figure 4 displays the location of the duplex fiber optic port in the fiber optic to serial box (RS-232 or RS-422).

Perform the following to connect fiber optic cables to the fiber optic to serial converter box and 882IS indicator:

IMPORTANT: Ensure there are no 90° or greater bends in fiber optic cables.

1. Unplug indicator and fiber optic converter power cords from power outlets.

2. At fiber optic serial converter, insert fiber optic cables through cord grips into the enclosure.

3. Flush cut the ends of the fiber optic cable with a suitable cutting tool, such as a fiber optic cable hot knife (PN 85548).
   IMPORTANT: The cut end of the fiber optic cable must be flush so the core and outside insulation are equal. Fiber optic core exposure can lead to failure.

4. Polish the ends of the fiber optic cable, per fiber optic polishing kit (PN 197384).

5. Insert the fiber optic cable through the locking nut and into the connector until the core tip seats against the internal micro-lens; then back it out 1/16 in (1 mm).

6. Turn the locking nut until snug

7. Route fiber optic cabling from indicator to fiber optic to serial converter.

8. At indicator, insert fiber optic cables through cord grips into the enclosure
   IMPORTANT: Cross-link fiber optic cables. The fiber optic connections between the 882IS/882IS Plus and the serial converter needs to be cross-linked (blue connection to black connection). The optical output of the indicator should be attached to the input of the serial converter, and the indicator input to the serial converter module output.

9. Repeat steps Step 3 through Step 6 to connect fiber optic cables to 882IS/882IS Plus.

10. Reconnect the power source for the fiber optic to serial converter box and indicator
