The remote pressure gauge is a fairly straightforward component within the broader category of pressure sensors. Inside this gauge, there's a potentiometer whose sliding end is linked to the gauge’s pointer. As pressure varies, the position of the potentiometer's sliding end adjusts accordingly. When the potentiometer’s terminals in the gauge are connected to the inverter’s supplied power, the voltage between the sliding end and "GND" becomes the feedback signal XF.
### Wiring the Remote Transmission Pressure Gauge with an Inverter:
To connect the remote transmission pressure gauge to the inverter, the three terminals of the gauge should be individually linked to the inverter’s +10V (power supply), GND (common ground), and X1 (multi-function terminal).
### Adjusting the Inverter Parameters:
For the inverter to work effectively with the remote pressure gauge, several key settings must be configured:
1. **Running Command Source**: Set this to "external terminal."
2. **Frequency Command Channel**: This should be configured as "PID."
3. **P Value, I Value, D Value**: These are crucial for fine-tuning the PID controller.
4. **Upper Frequency Limit**: Define the maximum frequency the inverter can output.
5. **Lower Frequency Limit**: Set the minimum frequency the inverter will operate at.
6. **Target Pressure**: This serves as the baseline pressure setting to maintain consistency, which can vary depending on the specific inverter model and its associated parameters.
These steps provide a foundational setup for using an inverter with a remote pressure gauge to achieve constant pressure regulation. Depending on the inverter model, additional adjustments or configurations may be necessary to optimize performance.
