Wheel Speed Dash 2

Postby westysprinter » Mon Jan 26, 2009 8:16 pm

I have fitted a Telemechanique 3 wire inductive prox to my front wheel sensing off the 4 brake disc bolt heads, the sensor iluminates when the bolt head passes the sensor so im confident the sensor is set up correctly, but no Dash-2 speedo reading when I spin the wheel, any thoughts?

I just struggled through this with my DL1.

After I re-read the spec sheet on the unit, I discovered that it requires a minimum 5vdc signal from the wheel speed sensor. For whatever reason the Cherry GS1001 sensors do not, but the Cherry GS1005 sensor do supply that when powered. I just happen to use Cherry sensors at work....

I also found that using car (unregulated) voltage resulted in speed reading errors (Looked like sensor saturation spikes), but when I used a 10vdc linear voltage regulator to power them, I get a very nice, clean, signal.
