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?

Re: Reverse PID
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.
