Product Introduction
The HONEYWELL R7247C1001 is a rectification flame amplifier module designed for industrial burner safety systems. It processes signals from ultraviolet (UV) flame detectors to confirm the presence of a stable flame and safely shut down fuel valves if the flame is lost.This module features a dynamic self-check mechanism that continuously verifies its own internal circuitry without requiring external test equipment. Field technicians value the R7247C1001 because its 2-4 second flame failure response time provides rapid protection against dangerous unburned fuel accumulation, while its plug-in design allows for quick replacement during critical outages.
Installation & Configuration Guide
Preparation (10 min)
Power down the burner control panel and lock out/tag out (LOTO) all fuel valves. Gather your UV sensor wiring diagram and a multimeter. Review the OEM manual for the specific terminal assignments. Put on safety glasses and insulated gloves.Removal (5–10 min)
Label all sensor and control wires before disconnecting. Gently pull the old R7247C1001 module straight out of the socket. Inspect the socket pins for corrosion or bending. Store the old module in an anti-static bag.Installation (10 min)
Align the HONEYWELL R7247C1001 with the socket pins. Press down firmly and evenly until fully seated. Reconnect the UV sensor wires and control circuit wires exactly as labeled. Verify all connections are tight and secure.Power-On & Test (10 min)
Restore panel power and observe the module status LED. Initiate a burner start sequence. Verify the module detects the UV signal and holds the flame relay. Simulate a flame failure (block the UV sensor) and confirm the module trips within 2-4 seconds.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Immediate Action |
|---|---|---|
| No Status LED | Missing control voltage | Check 24V/120V supply to module socket. |
| No Flame Lock | UV sensor dirty/failed | Clean UV sensor window. Test sensor resistance. |
| False Trip | EMI or bad ground | Verify shield grounding on UV cable. |
| Slow Response | Aging UV sensor | Replace C7012E/F sensor. Test FFRT. |
| Self-Check Fail | Internal module fault | Replace R7247C1001 module immediately. |
Dimensions, Mounting & Wiring Notes
The HONEYWELL R7247C1001 uses a standard plug-in module format that fits into compatible Honeywell flame safeguard bases. It weighs only 0.227 kg. When wiring the UV sensor, always use shielded cable and ground the shield at the control panel only to prevent EMI. Route sensor cables away from high-voltage ignition transformers. Ensure the module is fully seated before applying power.
FAQ
Can I use this with C7061A UV sensors?
No. The R7247C1001 is specifically designed for C7012E and C7012F UV sensors. C7061A sensors require different amplifier modules. Always verify sensor compatibility in the Honeywell documentation.I’m getting intermittent flame failures. What’s the first thing to check?
Check the UV sensor window. I always clean the quartz window first, as soot buildup is the #1 cause of false trips. Also verify the sensor is properly aimed at the flame.What does “dynamic self-check” mean?
It means the module continuously tests its own internal circuits during operation, not just at startup. If a fault is detected, it will safely shut down the burner without waiting for the next test cycle.Is this a direct replacement for R7247B1003?
Yes, the R7247C1001 is generally compatible with R7247B series bases, but verify the FFRT (flame failure response time) matches your safety requirements. The C1001 has a 2-4 second response time.What is the warranty on refurbished units?
We provide a 12-month functional warranty. All units are tested on dedicated Honeywell-compatible test racks with actual UV sensors before shipping.I lost the wiring diagram. Can you help?
We can provide standard wiring diagrams for typical installations. For complex burner sequences, consult the original OEM burner manual or a certified Honeywell service technician.
