Secondary handset stuck

kwinter · 12th October 2008, 13:42

I have the anodized handsets and I've been waiting to upgrade to the delrin sets until after DEMA hoping for some good updates. But it seems the next good hardware upgrade isn't scheduled until mid-2009. I've searched the old posts and can't find anything similar to my problem. The secondary is stuck in dive mode, with my current depth at 1,901 ft and the temperature at 11,775 degrees F. I guess my last dive was deep into the core of the earth.

I first noticed something odd that my secondary was completely dead in the morning after I had set up the rig the night before. No big deal, just change the battery. But odd since that SAFT had only about 2 hours on it. Then I noticed that when I put the battery in and the unit turned on, it didn't show the stack timer screen as usual. It went straight to showing my pO2. Also odd, but didn't penetrate my thick skull yet.

Then I tried to calibrate. No dice. It just would not accept pressing the button to calibrate. I took the battery out and put in another, but got the same thing. So after scratching my head for a few seconds, I realized that it was acting as if it was still in dive mode. That's the first time I bothered checking the top line of the display and saw those wacky numbers.

I clean my unit meticulously. I soak the handsets in a Salt-X solution after every salt water dive, followed by a long fresh water soak. I clean the battery contacts, threads and o-rings. I use Noalox. This doesn't sound like a battery problem to me.

I need help with this one. I thought there might be a problem with the pressure transducer, like a grain of dirt in there. But I didn't want to go poking around with a sharp object. And I can't possibly expect a fast turnaround from Kevin one week before DEMA. I checked the manual and it says "The pressure transducer hole (if present) should be filled with silicon gel to prevent entry of foreign particles. Gently wipe silicon across the hole to refill."

Joe - Is it more likely that the gel is gone and needs to be refilled or is this a symptom of a foreign particle? How do I fix this? And where do I get silicon gel?

I have a lot more diving to do over the next few weeks. I don't consider this to be a critical error as long as I can calibrate the primary handset and the secondary is pretty close. But if they start to drift apart, I'm screwed.

Can anyone help?

Ken, depth 1900 ft ( +/- 481m??) means depth sensor is dead.
must be replaced

Ken,
I posted on that a while back, but I cant get to my older posts for some reason.

Same issue happened to me when I had the old handsets. Just send it back to Kevin. It needs a part replaced. I think it was the pressure transducer.

The unit thinks it's always in dive mode, so it won't reset, which is why the PO2's always come up. It didn't effect the PO2 readings....

Mine had no problems once that was replaced.

I've since upgraded to the new handsets and haven't had any issues. They are great. I like them a lot better than the metal handsets. They are significantly lighter & having deco in the secondary gives me greater peace of mind and on occasion allows me to play with different GF's to see how deco differs.

I have the delrin handsets and had to return them to Kevin for the same problem. It was the depth transducer and it must be replaced.

the intersema pressure transducer failed.. This is why Kevin doesn't pot any of the units.. its a very simple fix.. This type of failure is unavoidable by any computer that uses the sensor (all the current major ones do).. The depth sensor has no effects an anything else except that you cant do any of the surface functions..

I will be at dutch next saturday finishing up a class.. If you get Kevin to send a sensor to me I could replace it for you next saturday..

Thanks everyone for the replies.

Richie - I knew I had read about that somewhere before, but couldn't find the old post. I had originally planned to upgrade to the delrin sets this winter when I send it to D-R for annual service. Then I decided to wait until the middle of next year after the new hardware upgrade that Kevin mentioned (no specifics, but I'm guessing at a computer interface). Now I'm not sure whether I should get this one fixed and wait or just upgrade now.

Joe - Thanks for the offer, but I can't get to Dutch next Saturday. And I'm not sure I can even get Kevin's attention this week with DEMA on the horizon. Will you be there Sunday 10/19?

Don - If I get it fixed like you, will my handset crack?:p

I'm diving tomorrow. I will calibrate on the primary tonight and see how close the secondary is. As long as they are close, I have no problem diving it since my HUD will be fairly accurate. I don't really need the other info. As long as I have pO2 monitored, I'm ok. My X1 and the primary will take care of the rest.

BTW, if I send it to Kevin for repair, what do I send? The whole head with both handsets? Or should I acutally disconnect the handset from the cable, or maybe the cable from the head? Or maybe I should just get the part from Kevin and hook up with Joe some time in the next few weeks?

Ken

diverreb · 13th October 2008, 01:01

If it goes back to Kevin send the head, without sensors & HUD, along with the Handsets attached.

Ken,
You are not that far from me.. if you dont want to give your head up just order the part from kevin, then we can arrange for you to stop by in the city.. It wount take long to swap out the sensor.. Most people can do it on their own, but since you are so close, I can check things out for you and make sure the handset is put back together properly...

I'm only planning on being at dutch on saturday to finish up the guys I started last month.. The only reason I would be there sunday is if I think they need extra dives..

I have a spare pressure sensor assembly in my car.. you can call jm and order one and have it shipped to me at their convenience.. just have trish confirm and I'll change it out for you this week if you stop by my house..
