Product Usage Instructions

Setting up the Actuator:

1. Configure the address, baud rates, parity, data bits, and stop bit according to your system requirements.
2. Ensure proper wiring connections.
3. Power on the actuator.

Using Modbus Holding Registers:

Refer to the provided table to understand the functions of different registers.

Calibrating the Actuator:

1. Activate relay functions as needed for calibration.
2. Request forced calibration using the appropriate register.

Monitoring Actuator Status:

1. Check the Motor Status register for information on the actuator’s current status.
2. Monitor relay statuses using the designated registers.

Frequently Asked Questions

• Q: How do I change the flow unit?
  • A: To change the flow unit, set the valve type in the valve section of the HyTune app.
• Q: What is the significance of the CurrentPos register?
  • A: The CurrentPos register indicates the measured position expressed in tenths of a percentage of the currently applicable maximum position.
• Q: How can I verify the relay status?
  • A: Use the Relay and Relay2 registers to verify the writing register status or to know the relay status based on parametrization.
