Sigma DTS speed sensor not working
Postby Mulger bill » Thu Aug 21, 2008 11:38 pm
It's the grey bike1 unit. I thought flat battery, but pressing the test button was OK. Replaced it anyway to no avail.
I've tried it with the bike2 sensor and it's fine, so it isn't the head unit playing up. I've gone thru the troubleshooting part of the manual without luck, but can't get on Sigmas www thanks to the filters at work.
Anybody got anything I might have missed?
Thanks

Although, I still have problems with cadence from time to time. Its was displaying double the cadence once and on another time it just did not read.
I'm not too happy with it after 2 months use.

I have the Sigma DTS as well and I agree that they are fiddly to set up.
Cheers.

Tried it, got the clicks, on both bikes, still no good.vitualis wrote:The sensor is quite large and only a small part of it is the ACTUAL sensor. When the magnet runs over the right part, should be able to hear a "click" noise...

Totally at a loss here, tried different magnets, positions, fresh batteries you name it. On both bikes, red sensor fine, grey one looks fine but nothing at the head unit
Ah well, give Tim a call.

So I went home, fitted it and tested it and it all worked properly. But when I went for a ride, the speed sensor worked for 17 seconds on a 45 minute ride. So I moved the speed sender up the fork, and now it was working ~ 50% of the time.
I rode over to the bike shop this morning, no speed at all this time and half way to the shop the cadence disappeared. At the shop, the guy says "I know how to fix this" - and fitted a new battery to the computer. And, of course, it all works perfectly now. The story he told me is that Sigma had a bad batch of batteries causing reception problems with the DTS, and had sent new batteries to each of their retailers to fix the problem.
What a shame they didn't mention this WHEN I BOUGHT IT!

If so, divide and conquer.
bike2 sensor works with computer, but bike1 doesn't.
the magnet is operating the read relays in both sensors (both clicking)
main (head) unit is working,
The wireless sensors also have a battery so that they can transmit the coded signal to the main computer.
Possible causes bike1 sensor not working:
low battery in bike1 sensor,
coded transmission of signal not rcognised by head unit,
faulty bike1 sensor,
....

Tried it again the next day after it dried, and it's now fine. Was almost gonna justify a new computer too. Bummer.

I dropped into the LBS and Tim had a spare in stock, easy as ...and some Ultegra brakepads
Twizzle, I lost a button on mine a while after buying, hooked it with a glove methinks I sent an email via Sigmas WWW and got a replacement head unit in the post from the AU distributor two days later

Have you got your computer mounted near anything else? I had to move my light/computer around so that they were far enough away from each other not to cause interference and still be able to pick up the sensor on the forks - but it's still a bit hit and miss.

Impressive customer service But those buttons are held in pretty well - even snagging on a glove shouldn't pull a button out (I just tried really hard to pull a button off the broken computer and it isn't moving!).Mulger bill wrote: Twizzle, I lost a button on mine a while after buying, hooked it with a glove methinks I sent an email via Sigmas WWW and got a replacement head unit in the post from the AU distributor two days later

But... I definitely broke mine, ie. it was my own fault. I dropped my computer on the road, and the plastic edge that retains one of the corners of the reset button broke off.
Having disassembled the first computer to get the water out (it went through the washing machine), I can tell you that all of the buttons and contacts have seals to keep water out - as long as they aren't immersed in deep water, they stay dry. My second computer had two trips through the washing machine - low water level - and survived.
The weak point in the design in the ease with which the case is damaged when dropped. If only they had a silicone rubber cover around the edges to protect it...

Blardy good idea, that. Years ago I had a cheap Sigma computer that died when I dropped it from less than 1m onto concrete - no external damage but I suspect the computer board cracked. A silicone 'bumper bar' could help that sorta thing as well as damage to the plastic body, and could have waterproof button covers integrated into it. Could even make it replaceable so you could colour match your frame...twizzle wrote:The weak point in the design in the ease with which the case is damaged when dropped.

Anyone know someone who could do a small production run? We could brand them 'BNA'

Thoroughly agree that the case would benefit from a little shock absorption around the edge. I've dropped mine a couple of times and chipped the corner. Now occasionally if the button gets snagged it will swing out from the body. Thankfully it generally stays put where it should.twizzle wrote: But... I definitely broke mine, ie. it was my own fault.

Good thinking Strawb, thanks. I tried it with lights (10W halogen, Basta Superflash, cheap LED lidlight) and without. In the shed, besdie the road and on the train all without luck. Glad the LBS had a spare in stockStrawburger wrote:Have you got your computer mounted near anything else?

Twizzle, I agree with the customer service bit, I only emailed asking about the availability of spares, a new head unit went above and beyond.
Oh yes, a silicon guard would be the ducks guts.

The speed sender failed yesterday. It had dropped speed for short periods of time over the last couple of weeks, but yesterday only provided speed for a couple of minutes. Spinning the wheel gave 'clicks' but no light... but just R&R'ing the sensor was enough to bring it back to life again - for a while, anyway.
So I went past the bike shop this morning. New battery in my sender = totally dead sender. First new sender out of the box would either flash, dim flash or no flash. Second new sender out of the box works fine. Now, I know a sample size of three isn't much... but a 66.6% failure rate isn't too healthy.
Mind you, the first new sensor was working perfectly again after the battery was changed - which just goes to show that the battery issue that was mentioned previously by the shop isn't limited to the display unit, and they probably should have changed all three batteries at the time.

Anyone worked out how to get these things to work consistently? I have a unit which I put on the MTB, worked okay and then on Friday's ride it worked for 300 metres and then stopped getting a signal from both the cadence and speed sensors. Nothing has changed. Between Sigma and Garmin I am getting so over bloody bike computers

Good question.Aushiker wrote:Anyone worked out how to get these things to work consistently?
I have two separate Sigma computers on two bikes and had zero issues in over 12 months...up until last month when one of the units (both wired) just stopped working part way through a ride.
Long story short...I took the "magnet" off the spoke and quickly worked out that it wasn't magnetic anymore. Say What? Closer inspection revealed that the magnet itself sits in a plastic sleeve and was no longer present. Of course I'd mounted it on the spoke so that if the magnet ever came loose from the plastic sleeve it would be ejected at high speed.
Had an old spoke magnet from a long deceased Cateye computer and all is now well again. At least in my case it was black and white...no magnet = computer not work. Solution = replace magnet. But when they work 50% of the time for no apparent reason...

Having dealt with a very temperamental Sigma wireless unit on my Tarmac for the last few months, I tend to agree.twizzle wrote: Sigma wireless is !! BAN ME NOW FOR SWEARING !!.
I'm thinking about sticking the trusty old cateye wired back on.

Is there such a thing as a reliable wireless computer, preferably with HRM?
I have put a Blackburn Nero on Anne's bike but really haven't tried it out much yet. I am hopping the new 2.4 (?) ghz designs are better.

An electronics engineer explained to me why my Sigma didn't work any more...the LED can fry the electronics in the speedo,particulsrly Sigmas. I changed speedo brand, no probs since.
