Part 4: Installation & Configuration Guide

Phase 1: Pre-Installation (Estimated Time: 20 minutes)

⚠️ Safety First:

1. Coordinate with your station operations manager to place the corresponding automation cell into a maintenance state. Never pull an interface card while safety trip loops are active.
2. Trip the auxiliary control power distribution breakers feeding the target OCS rack chassis.
3. Apply standard Lockout/Tagout (LOTO) padlocks and warning tags to the rack’s primary power switches.
4. Wait 5 minutes for the rack power supply filter circuits to discharge completely.

Tool Preparation:

• Static-dissipative grounding wrist strap
• Flathead instrument screwdriver (2.5 mm precision blade)
• Phillips screwdriver for securing rack panel screws
• Fluke 115 Digital Multimeter

Phase 2: Removal & Installation (Estimated Time: 20 minutes)

1. Verification: Confirm with your multimeter that the field wiring terminal strips read 0 V.
2. Removal: Label all connected field wires. Carefully loosen the terminal block screws and remove the wires. Back out the top and bottom panel mounting screws and slide the module out.
3. ESD Protection: Use an ESD-safe workspace and wear a grounding strap.
4. Jumper Replication: Compare the raw base board (HESG216678B) of the new card with the old one. Match all physical jumper or DIP switch settings. These are critical for address mapping and signal scaling.
5. Insertion: Slide the card into the slot until the backplane connector seats firmly. Secure the faceplate screws.

Phase 3: Power-On & Diagnostic Testing (Estimated Time: 15 minutes)

1. Monitor LEDs: Restore power and observe the RUN (Green) light. If the FAULT (Red) LED persists, power down immediately to check for improper seating or jumper mismatches.
2. Signal Verification: Use an engineering terminal to confirm that the central controller detects the slot address. Exercise the I/O points (e.g., simulate a signal change) and observe the corresponding channel LEDs on the faceplate.

Part 5: Customer Cases & Industry Applications

Case 1: Restoring Diagnostics for an OCS Control Cell

Situation: A manufacturing plant using an Advant OCS architecture lost visibility over a section of their I/O monitoring due to a faulty IW93-2 module. Action: We supplied a New Surplus unit from our inventory. After the customer duplicated the internal jumper settings, the module initialized instantly, restoring full I/O functionality to the control rack without requiring system downtime.

Case 2: Strategic Spares Allocation

Situation: A reliability team managing legacy paper production control systems sought to secure critical spare parts before the global market supply dried up. Action: By purchasing an un-used HESG440356R1 module, the facility ensured they had a reliable, plug-and-play backup, avoiding the risks associated with refurbished pull-outs.

Part 6: Frequently Asked Questions (FAQ)

Q1: How do the part numbers IW93-2, HESG440356R1, and HESG216678B relate?

• IW93-2 is the catalog code.
• HESG440356R1 is the global ordering number.
• HESG216678B is the base circuit board number stamped on the hardware. These numbers identify the exact same physical module version.

Q2: Why is matching jumper settings critical?

The IW93-2 can sit in various slots in the rack. Jumpers determine the unique communication address and signal scaling for that specific slot. A mismatch will cause the module to be “invisible” to the controller or report incorrect process data.
