Troubleshooting Quick Reference

Symptom Possible Cause Relevance to this Part Quick Check Method Recommendation
No power to modules Faulty base backplane ✅ High Measure 5VDC and 24VDC at module pins Replace baseplate
Modules not recognized Bad backplane connectors ✅ High Visual inspection for bent pins Clean or replace IC693CHS397
Intermittent operation Loose mounting or vibration ✅ Medium Check all module seating and base screws Secure base and reseat modules
CPU fault light on Base power distribution issue ✅ Medium Test with known good CPU Swap base if issue follows
Expansion rack comms fail Base configuration mismatch ❌ Low Verify dip switches and addressing Check CPU and expansion settings

Take clear photos of the baseplate and installed modules if you continue to have issues after basic power and seating checks.

Frequently Asked Questions (FAQ)

Is the IC693CHS397 new original? Yes, supplied as New Original / New Surplus from GE Fanuc inventory with traceability.

How many modules can this baseplate hold? Five slots total. Typically one slot for the CPU and the remaining four for I/O or communications modules.

Is this baseplate expandable? Yes. You can add remote I/O racks using the appropriate expansion modules and cables.

Do I need a separate power supply? Yes. The baseplate requires a compatible Series 90-30 power supply module installed in the designated slot.

Can I use this as a remote I/O base? It is primarily a CPU base. For remote I/O, consider dedicated expansion baseplates like the IC693CHS398.

What is the power consumption of the empty base? Approximately 270 mA at 5 VDC for the baseplate itself.

What warranty applies? 1-year warranty on functional performance. We test each baseplate for proper backplane operation before shipping.
