Smart battery sense No blue light

Got the smart battery sense today. Hooked it up to my 48 volt battery bank, did not get blue light flashing or no error light. Charge controller is a smartsolar 150/70-tr. Checked fuse, looks ok. Charge controller works fine with ve. Connect. Any ideas.

There is really only 4 things that can cause a no-go.

Reverse polarity.

Damaged fuse.

Damaged fuse holder.

Broken SBS.

After you have checked the first 3, consult your retailer.
