DL1 showing unreasonably high voltage inputs on Monitor Lite

[marck_c]

Hi,

I have a DL1 that I am installing on a race car. When I connect the sensors to the input blocks on the back, I get ridiculously high voltages when viewed on Monitor Lite. As high as 55v! The battery voltage shows 18v on the Monitor.

However when I check the same inputs with a voltmeter I get ~1v. I previously sent the unit back to RT, and they reported that nothing was physically wrong with the unit, and that it just needed a reflash.

I downloaded the .hex file and reflashed the unit myself 3 times - successfully. But this did not fix the problem. Has anyone else had this issue or can anyone suggest how to fix this problem?

There is a input calibration routine but you need a regulated source. RT can give you the details, and/or can do it for you. I've never had to do one and only had 1 customer in 4 years need it.

Just curious is this why you sent in previously or is this a new issue they didn't know about when you sent it in before?

It had the same problem before I sent it to them. They said they reflashed it anc calibrated it. It worked fine for a day or two then the problem repeated itself. I have'nt even started the car. Are you familiar with the recalibration procedure?

[jlucas]

Sorry, no I'm not. I just know it exists but if your unit won't hold a calibration, I'd be asking them for a a replacement.

marck_c, could you contact me directly with regards to this issue please. Its better for us to deal with repair inquiries directly. gummi(at)race-technology.com

Ok, I contacted RT and they sent me a procedure to recalibrate the voltage inputs. I applied it and it was successfull. If anyone else is interested I can post it here.
