AVP provides a valve position feedback unit as an optional accessory, and users can monitor the valve's movement in order to find problems early.

Self-diagnosis
AVP provides a self-diagnostic program to ensure that the fault of the regulating valve is quickly determined.

4. Suitable for single-acting/double-acting actuators at the same time (double-acting function is optional)

Through the inverting amplifier, AVP can be applied to double-acting actuators.

Self-tuning of internal switches

Steps:

1. Adjust the air source of the filter pressure reducing valve to the rated value of the execution structure, and input a signal of 18mA±1 mA to AVP100

2. Press the "UP" key for 3 seconds Custom Bibcock Manufacturers until the valve moves and auto-tuning starts, then release the button

3. The valve knows to perform full-open-full-close back and forth twice, and then stop at about 50% of the opening, and then stay at the opening position of the input signal (18mA). The whole process takes about 3 minutes

4. After changing the input signal, check the opening and auto-tuning is complete

5. When the auto-tuning is in progress, if the input signal is lower than 4mA, the auto-tuning is interrupted and the auto-tuning must be restarted. After the auto-tuning is completed, keep the input signal above 4mA for at least 30 seconds before the auto-tuning parameters can be stored in the AVP.

6. During the auto-tuning process, if you connect the SFC handheld programmer (pay attention to the positive and negative poles) to the AVP, press the ID key on the SFC handheld programmer, and the auto-tuning parameters can be displayed on the SFC LCD screen.
