Instead of waiting for maintenance to arrive, an operator or programmer can immediately bypass the alarm. This keeps the operator active and the machine in a "pending" state rather than a full shutdown. 3. Verification of Issue

If the 701 alarm persists even after checking the fans, you likely have a faulty cabling issue or an amplifier malfunction, not a simple fan failure. Conclusion The fan exists to protect expensive amplifiers

The benefits of this architecture are manifold:
