How to use smc pressure sensor for laymen

Today, I happened to meet the debugging of SMC digital pressure reducing valve:

There are three buttons on the panel: up, down and down.

Press "s" to enter the setting mode, and "P 1" or "N 1" will be displayed. P 1 is the normal output mode, and N 1 is the standby output mode. You only have one out 1, and only P 1 and n 65438+ will be displayed.

P 1 flashes a value alternately, that is, press the up and down keys to adjust the size of this value. This value is the value we set. For example, if 5 bar is greater than this value, there is an output.

After the setting is completed, press the "S" key to complete the setting.

If there are two outputs out2, set P2 or n2, and if there are no outputs, ignore them.

Then press "s" and "P 1H" or "P 1L", and a numerical value will appear, that is, set the upper and lower tolerances, such as 0.5 bar, indicating that 4.5bar has output.

If you press "s" for more than 2 seconds, you will enter the function setting "F0" ... "f1". Generally speaking, you don't need this, just a "F0". Ignore it.

If you see that "HYS" means hysteresis, that is to say, there will be output when it is greater than 5,0 bar, but if there is air leakage, there will be output when the pressure drops to 4.5bar.

If you press "Up" and "Down" at the same time for about 1 sec, it will be reset and the pressure will be reset.

The displayed pressure is the pressure of the current pipeline. Rotate and pull out the upper cover of the pressure reducing valve, and try it clockwise and counterclockwise. The pressure will change. Adjust to the pressure you need and press the upper cover back.
