Hi to all,
I recently bought a jrk 21v3 MC and the LACT8P-12V-20 Linear actuator w/feedback.
I had some little issues getting off the ground a couple weeks ago and talked to support. But then had to leave it all until two days ago.
2Days ago I brought it all into my house and laid it out. Actuator, jrk21v3, analog pot and a 12v battery, along with it’s .9amp charger.
Taking my time with the config utility I was able to easily get the jrkv3 up and running, responding well to my 10k pot input.
Fwd/back, etc. All good!
Today I did the same thing, just reading about PID and tuning , etc. All good.
I then took my system apart, took it outside to my application and hooked everything up. When I powered it up. The Linear actuator took off in the extend direction all the way to the limit switches.
I checked, rechecked, etc. Then decided I had to bring out my laptop and see the issue via the config utility.
Hooked up the laptop and found I had lost my analog-input. Gone. Sitting @ zero.
I checked several things outside and then decided to bring it all back in and lay it all out.
As it is now, I have no controllable analog input. The analog input rapidly fluctuates between 12-16.
I have tried different pots. I have tested via multimeter the v+ and grnd- from the analog pins @ my pot and all is well there.
There seems to be a problem on the rx pin?
I don’t know what else it could be and just as importantly I cannot for the life of me figure out how I killed that function.
I wasn’t in a hurry. No dangled wires. All wires have connectors on them to aid in prevention of inadvertent shorts.
Please advise?
thanks, tom_w
