3.4 Installation & Operation Guidelines

1. Pre-installation Inspection

   Confirm model matches FBM202 high-temperature thermocouple module; inspect housing without cracks, intact compression terminals and undamaged D-sub pins without bending or oxidation. Cut off cabinet 24VDC auxiliary power before all wiring operations.

2. Wiring Procedures

   • Connect thermocouple dedicated compensation cables to corresponding compression screw terminals, strictly follow positive/negative polarity; different TC types cannot share one channel;

   • Separate high-current power cables and TC signal cables to avoid coupling interference;

   • Tighten all terminal screws evenly with standard screwdriver to prevent loose contact and temperature measurement drift;

   • Link Type 4 37-pin termination cable between P0916RC D-sub port and FBM202 baseplate interface.

3. Power-on Debugging

   Restore cabinet auxiliary power, launch Foxboro Evo DCS configuration software; enter FBM202 module diagnosis page to select corresponding thermocouple type for each channel, verify stable temperature readings, calibrate cold junction compensation offset when deviation occurs. Extend filter time for furnace high-interference working conditions.

4. Routine Maintenance

   Clean terminal dust and oxide deposits every 3 months; re-tighten compression screws in high-vibration furnace workshop environments; replace P0916RC immediately if persistent temperature reading drift, channel open-circuit alarm or internal CJC circuit burnout occurs.

5. Safety Precautions

   Live wiring and hot plug/unplug of D-sub connectors are strictly prohibited; do not access AC high voltage signals exceeding 30V to avoid burning weak TC signal conditioning circuits; this product cannot be installed in open-air, humid, flammable and explosive hazardous atmospheres.
