FAQ

• Q: How does the readback contact work?
  A: The contact closes only when both fans exceed 1,500 RPM. This confirms adequate cooling before enabling system operation.
• Q: Can I replace individual fans?
  A: Yes. The FANWR-24R uses standard Papst 4184N/17X fans. Replace with identical models to maintain performance and readback calibration.
• Q: What happens if one fan fails?
  A: The LED next to the failed fan turns off and the readback contact opens, signaling a fault condition requiring maintenance.
