Connecting the current sensor to the DDR244-13ABC-T

[valik1979]

Hello, could you please tell me how to properly configure the input from the current transformer DDR244-13ABC-T. We used to use DRR245-21ABC, but it has been discontinued.

Good Morning,
the current transformer (CT) need to be connected between the pins 18-19.

To configure the input you can look in the GROUP S - ct - Current Transformer of the DRR: here you will find all the parameters related to the current transformer.
parameter 287 ct F. Current Transformer Function is dedicated to the frequency of the input 50/60 Hz or DISAB.
parameter 288 ct v. Current Transformer Value is the scale of the current transformer.
ecc...

The instruction to set a heater break alarm are found in the chapter 7.8 of the manual.
I will leave a link that lea to a page where you can download the manual.

Good Morning,
The that you see on the display "E-05" is related to the probe not the Current transformer.

Did you connect anything on the analogue input?
If so, did you set the sensor parameter correctly?

if you didn't connect anything in the analogue input you can set the sensore to 0-10V, this way even if nothing is connected you can bypass the error "E-05"

If you want to visualize the AMPERE measure by the CT you need to change a Display parameter:

parameter 278 vi.d.2 Visualization Display 2 to "AMPer."
like this you will visualize on the red display the amepere measure by the CT.
