Programing problems with a DVB01

[CanuckRV]

I installed a DVB01 in my 97 roadtrek 190 Popular to turn on my Renogy b2b charger. I was following Mike's tutorial and everything was going fine until I got to step 19 of Mike's programming example when setting the voltage to 13.6 as per my voltmeter when I got above 9.9 I did not get a ten I got F0.0 is the F suppose to be a one or have I screwed something up. Right now I have it set as F3.6.
Thanks for the help

Are you certain that your voltmeter is set to an appropriate range? If you have it set to a 0 - 10 volt range you are likely to get this result. Make certain that you are set to a 0 - 20 volt range.

[CanuckRV]

Where do I check that?

[JohnnyFry]

Most volt/multi meters have a range/function dial switch. Volt function needs to be set to 0-20 volt range DC

[CanuckRV]

it's not the multimeter that's the problem it's the DVB01 I know how to use a Multimeter.

What is the voltage using a volmeter? EDIT other than your DVBO1

Did you see this video?

Yes I have watched it but it does not go into calibrating the voltage going into the unit.

Perhaps this is not calibartion but programming of digits displays?

It does seem like there's a problem with the LED display. I would have gone through that step when I calibrated a DVB01 -> https://www.classbforum.com/forums/f...tml#post122271 <- and it displayed a 1 not an F.

[CanuckRV]

Hmmm, I hope it's just a display issue I guess I'll take the Roadtrek for a test drive to see what happens.

[CanuckRV]

Seems to be a display issue, not a function issue, started it up after 30 seconds the B2B kicked in lowered the voltage with a controller and it stopped so good to go.

Possible that it's a bad LED in the 10s digit - so you ever seen a 1 in that LED? When not in programming mode, the display should read out the input voltage (12.X). If it read F2.X, then you know it's a bad LED. If you don't have a spare you can hook up (which is not a bad ides), just try it to see if the relay closes at 13.6 volts.

[CanuckRV]

It closes at 13.4 where it's set 13.6 is the line voltage that's coming from the alternator. It seems to be working fine except for the line voltage display.

What voltage does it open at? Does the unit have settable hysteresis or a given spec?

[CanuckRV]

It will come on 30 seconds after it detects 13.4 from the alternator and will shut down if the voltage drops below 12.8 set by me.
