85. What are the precautions for switching between two machines?

1. Contact the response team, pay attention to the operations, and switch the main air supply’s automatic protection mode to manual. 2. Increase the air flow rate of the standby unit to match that of the main unit. 3. Raise the outlet pressure of the standby unit to a level slightly higher than that of the main unit. 4. Perform the switchover slowly, ensuring that there are no significant fluctuations in the main air flow rate; monitor the outlet pressure and the regenerator pressure closely. 5. Organize the control panel display related to the unit’s automatic protection functions, switching the protection mode from the main unit to the standby unit to prevent the standby unit from stopping, which could lead to an interlocked shutdown. 6. After the switchover is complete, confirm that there are no issues with the standby unit before shutting down the main unit.

Maintain a stable air volume to prevent pressure fluctuations； The main air supply protection of the device is disabled.
