ATR244-23BC-T Output Control and Display Screen

[otis5842]

Hello,

I have two questions regarding an ATR244 controller:

1.) I am trying to perform an Ab.diF between A1 and A2, which are reading two K-type thermocouples and display the delta T on the controller screen. I have accomplished this much using LabSoftView, however my next step is to produce an output to an external relay when my setpoint is reached. I have explored many options in LabSoftView and cannot produce this functionality. The only success I've had is with the 0-10V and 4-20nA outputs, which remain active unconditionally and independent of the setpoint condition being met. What are the recommended steps to produce an analog output when a setpoint is met?

2.) My controller screen was consistently displaying readouts, setpoints etc. but now the screen is no longer displaying anything and seems to be in some sort of a sleep mode. only activating when the "SET" button is pressed or when a setpoint is reached. Is this an power issue or a programming issue? If so, how can I remedy this problem?

Thanks

Hello,

1.) To set up an analog output as a command output, so that it triggers when the setpoint is reached, you should modify Par. 35 to "c0-10" or "c.4-20" for the analog output AO1 on terminals 10-11. Then, set Par. 38 to "cooL"

2.) Try checking the display parameters, specifically Par. 279, which should be set to "diSAb.".


Please, let me know if this works or if you need further assistance.
