7. Firmware – The “BKE” suffix indicates a specific firmware version; verify compatibility with your Mark V/VIe system.

8. Spares – Lead time typically 8–10 weeks; maintain a spare module for critical installations.

Precautions

• ESD Protection – Use wrist strap and anti-static handling during installation, especially since the module is conformal coated.

• Conformal Coating – Do not attempt to remove or scratch the conformal coating, as it provides critical environmental protection.

• Analog Input Wiring – Use shielded twisted-pair cables; ground shields at the module end only.

• Thermocouple Wiring – Use thermocouple-grade extension wire of the same type; avoid copper wire between sensor and module.

• Power Wiring – Ensure proper power connections for field devices; observe correct polarity and voltage ratings.

• Cold Junction Compensation – Ensure cold junction sensors are protected from external heat sources or drafts.

• Analog Output Wiring – For 4–20 mA outputs, ensure the loop resistance is within the module’s drive capability (750 Ω max).

• Avoid Ground Loops – Connect earth lug directly to system ground with 6 mm² wire; avoid ground loops.

• Commissioning – Verify input readings with known signal sources and test outputs with dummy loads before field connection.

• Firmware Updates – Use only GE’s official tool for firmware updates.

• Periodic Inspection – Check for dust accumulation on heatsink and connector integrity annually; clean as needed. Do not use solvents that could damage the conformal coating.
