Problem with alarm 2 output on atr 144

Hello,

I did not find a related topic on this subject. I am using an atr 144 controller on a simple heating application. Everything works OK, the only problem is the output of alarm 2. It is connected on PIN 6 and 7. When the Proccess value goes over 50 I would like to turn on alarm 2, so I get 24 V on PIN 6.

What parameters should I set so I can achine the desired result.

Thank you for your answer in advance.

Good Morning,
To activate the alarm associated with Q2, you must set in Group D [AL.1]> Par.62 [AL.1.F. ]> "Ab.uP.A." only if in Group B [cmd.1]> Par.18 [c.ou.1] is set to "c.O1".
To set the threshold must exit the configuration and press SET.

BR,
