LED confirmation on VM129

I have connected the VM 110 en VM129. Everything is working alright, except that the confirmation LED’s on the VM129 are not burning. (if you put all the surrounding lights out you can see something !!!)

What can be the solution for this problem?

Increase the relay card power supply. Probably, you are using a DC supply instead of an AC supply.

Thanks, you’re right about the power supply. Must I change it in AC or can I increase the DC voltage?

Can you advice me for the right power supply?

Change to AC or increase to 14VDC

Thanks.
