Can I do a control on off with a pixsys atr142ABC?

Post by user17188 »

Hello,
I want to use ATR142ABC to do a ON-OFF control, however, I dont know how programm this.
I will use a equipment of pressure two wires, and I need to activate an output relay, whit a set point.

Can you help me with this information? or can you give me a guide to do this?

Hi,
Your pressure sensor what type of output is using? 4-20mA (passive loop) or 0-10V output signal?
If you need the ATR142 user guide, you can download it using follow link (download section).

Hi,
the user guide explains you how to connect the 2 wire sensor: ATR pin 12 to sensor output and pin 9 to sensor supply.
Use this follow parameters:

2.[SEn] = "4.20"
4.[Lo.LS] = --> minimal sensor range to work
5.[uP.LS] = --> maximum sensor range to work
11.[Act.t] = --> depend of type regulation you want to work: heat or cool.
15.[c.Hy] = --> insert your comand histersis

Save all parameters and set your comand setpoint using the arrows.

Best Regards

Thank you very much for your answer, however, I require that at a certain pressure value, a relay output be activated. According to the manual I understand that the type of regulation(HEAT OR COOL) works with a PID control and basically I only require ON-OFF control, I just do not know how to carry out this type of control with the ART142ABC.

Hi,
the parameters that I posted it is for work in a simple regulation (no PID regulation). Only ON/OFF using a histeresis. I advise you to reset the ATR142 using 9999 password and after if you change only the parameters that I posted, the ATR will work in a basically configuration.

Best Regards
