Reverse PID

Hello, We want to use the DRR245 for reverse PID. That means that we connect a 4-20mA pressure sensor at the analoge input, choose a setpoint and want 10V output when the pressure sensor detect 4mA. So a low input value generates a high output value and a high input value generates a low output value. Can this be done with the DRR245?

Hi,
Please reset the DRR245 using the password 9999 and after the reboot insert the 1234 password and set this follow parameters:
1.[C.out] = "C.0.10"
2.[SEn] = "4.20"
6.[Lo.Li] = "4"
7.[uP.Li.] = "20"
11.[Act.t] = "Heat"
18.[P.b.] = "16"
Remember to shortcut the PIN9-10 to enable the Volt output.
Set your setpoint to value 12.
Best Regards.
