REPLACEMENT UNIT?

4 posts in this topic

WE have been using the E5CK controller using a 0-10vdc ultrasonic sensor to control a product loop. The controller is outputting a 0/10v signal that is scaled to 2-7v as reference to maintain the loop, like a dancer.

Our E5CK's are failing due to the plastic button actuators breaking off inside. Our Engineers bought a E5CN-H as the replacement for the E5CK, but I have not been able to replicate the scaled output. I get 0v, or 10v and I have not been able to scale this output. Is there a way to scale the output, is this the right controller to replace the E5CK?

The full numbers are E5CK-AA1-500, and E5CN-HV2M-500.

Is your output scaled from 2-7 or just limited to 2-7?  You could use the MV Low and MV High limits to limit it to 20-70% of output.   

I looked at the E5CK and I don't even see a way to scale that from 2-7 V, only limit it from 2-7.  Of course I could be overlooking something.

Here is the MV Limit parameters for the E5CN, just in case:

Michael,

I checked with the engineer and you are right, the output voltage is "clamped" at 2 and 7 volts. Your solution worked, thanks for the help!
