Hi,

I need to convert my input signal (which is PT1000 Temperature Sensor) to 4-20ma current output.

with following parameters set on my controller, the output doesn't vary against change in temperature value (with voltage set as output) .

C.out : c0.1
Sen: Pt 1t
LoLi: 0
uPLi: 50
retr: uo.P
LoLr: 0
uPLr: 10

Kindly advice and Highly appreciate your support on the same.

Hi,
"LoLr" and "uPLr" are wrong:
in "LoLr" you must insert the temperature read so the regulator generates 4mA.
in "uPLr" you must insert the temperature read so the regulator generates 20mA.

So I think they can be 0..100°C not 0..10 (probably you are reading a temperature always greater then 10° so the regulator gives always a 20mA output.

Also "retr" is wrong. if you want to generatre 4..20mA output, you must set it as "mA.P"

Check also jumpers position to enable 4..20mA output (page 14)

Hi, Thanks for your advise, Its working now.
