March 27, 20197 yr Dan, I heat my 26x32 shop and it doesn't seem that there's a significant heat loss. I'd suspect the same would apply for A/C. But, my shop is separate from the house. In a balanced HVAC system, it might not be a good thing. Especially, if the DC is in use a lot.

Mine is in a sound proofed room adjacent to the shop and has a return grill cut into the wall between the shop and the DC enclosure. so all the air returns to the shop,and I can tell on a cold day the return air is warmer and heats the shop.

March 27, 20197 yr On a cold day, I've felt the air coming out of the DC. It's warmer than ambient air but not close to as warm as in the shop. But, I guess there is a heated molecule or two sneaking out. It's a small price to pay for the benefits, though. Edited March 27, 20197 yr by Gene Howe

I could lower the sensors but the black trash bag in the garbage can might not let the sensor "see' through to detect the level of chips if I lower it. and I hate to cut a hole in both sides of the bag, it would defeat the purpose of the bag. Herb Herb What kind of sensor is it and where can we get one?

Gerald, they are garage door sensors and they used to be sold on ebay that had a circuit board that the signal would activate a circuit to raise the garage doors. Only in this case it would turn on a low voltage light to show an alarm. It could also activate an audio alarm . I bought a strobe light from the auto parts store and mounted it on the wall. My electrician wired it up. There is a plastic window about 2" in diam on each side of the cyclone outlet to the dust bin. they are mounted to look thru and when the beam is interrupted it will set off the alarm. Before I used this set up ,One time I completely filled my canister filters with chips and sawdust. It was a huge mess to clean up. Here are some pictures. Herb

There are a few You-tube videos on it as well. Oneida Dust Sentry Level Sensing Kit I was discussing this with my electrician tonight,about my sensors,and any options to get them to go off before the bin gets completely full. He sent me an email that he will put together one that mounts over a hole in the top of the bin that I can set for any level i want and adjust it to what works for me. He said he is ordering the parts to put it together. So looks like I get a new better system. I will update when he gets it installed. It will be awhile. I think it is similar to what you showed, Dave, only he is going to use parts I have + some new ones he will order. Herb Edited March 28, 20197 yr by Dadio

Thanks Gerald, You may have to get a circuit board to go with those that controls a switch to power the alarm. My understanding is that feature is part of the door opener, the one I have a guy made to adapt the sensors to the new task. He was selling them on ebay. I looked today, but not knowing what I am looking for don't know if they are still there. I will ask my electrician tomorrow if he knows where to get them. Herb
March 28, 20197 yr My Dust Deputy is bolted to clear plexiglass so I can see into the catch can. Mine is easily accessible.

But, my shop is separate from the house. In a balanced HVAC system, it might not be a good thing. Especially, if the DC is in use a lot. I have a furnace blower rigged up to blow air out the window. I open the window on the other side of the shop and blow the dust off of everything which is then blown out the window. It doesn't take long for the shop to reach outside temperature and the DC moves a lot more air than the blower. I think the DC would suck the air down the chimney if a window wasn't opened. It is a basement shop. Edited March 28, 20197 yr by HandyDan

The problem was some erratic behavior it was producing.
March 29, 20197 yr 14 hours ago, Gerald said: I just thought if that is all needed I still have the opener . The problem was some erratic behavior it was producing. Erratic behavior or not the feature that controls the sensor may be perfectly functional. The beam functions as a normally open circuit and the beam interruption causes it to go closed. This sends a signal to the opener to stop. It is just a matter of rigging the "OFF" signal to trip the warning feature. So, it sounds like you have what you need to do this, minus the warning feature. Perhaps @Artie can weigh in here for a wiring solution.
March 29, 20197 yr You will need to find the wiring diagram and determine which wires go where, maybe in the case or online. There must be a transformer that powers the low voltage, I think my sparky used a separate trans former to supply the low voltage rather than powering the whole card with line voltage.
March 29, 20197 yr It should be...from what little I know, be careful poking around in there after it has been powered up and powered down. There can be capacitors that store high amperage even though low voltage that if discharged through you is enough to put you on the bottom side of the green grass.
March 30, 20197 yr Circuitry-wise, should be easy enough. It’ll be a 12 or 24 volt powered device. Do you want it to turn on a light? Horn? Turn off the DC? This will involve the need for a relay, controlled by the beam detector. Making it operational, and convenient might be challenging. I haven’t read most of the thread, but if the beam is focused across the collection barrel on the DC, will the falling sawdust/chops activate it? If anyone is serious about this and will send me some detailed pictures/drawings, I’m sure I can make something that will work, pass code.
