GEM connection via DB

Ben,

Will this address Ryans vertical tiling of his loads and live data view?

Vertical tiling is due to a missing JS file. It'll be included in the update.

Beta update up:

http://www.brultech.com/home/software/i ... etsoft/1/4

Changes:
- Improved clock fail safes.
- Day/Week/Month/Year picking on modules improved. Can now use calendar in each mode.
- Modules now show negatives, feedback appreciated on scaling/etc.
- Speed *may* be improved. Haven't had a chance to try it across multiple DashBoxes.

Current known issues:

- Under devices, line graph can timeout when generating data.

Before I go and add jumpers to stabilize the few erroneous loads, I'd like a little input... The example I have is the circuit that my air compressor is on. See here.

Even with the circuit off, I see ~17W. I'm monitoring a single leg of the 240V load (and doubling it in the GEM). The M-40 CT is in a load center in my garage and connected to the GEM via ~25ft of CAT5.

I'm seeing similar (idle/circuit off) consumption with my EVSE which is also monitored in the load center in my garage and connected via the same CAT5.

These open circuit loads seemed higher than what I saw others experiencing while adding jumpers and changing offsets. I've confirmed the GEM is setup for the M-40's. Is there anything else I should address prior to adding a jumper?

1. Confirm the line voltage with a true RMS DMM. If it doesn't match the GEM calibrate it so it does match. Take this measurement at the service panel to ensure accuracy.

2. Move the wire to another channel and report back if you see the same spikes.

3. If you haven't updated the GEM / DB please do so.

4. If all the above fail to correct the spikes please do add in a jumper wire while the GEM is un powered.

5. You should not have to make any changes to the current off set.

My DMM is measuring about .5V higher than the PT... Would that .5V cause an issue?

No.

No.

I now have all my loads in a grid, but still seeing 17W from my air compressor circuit which is turned off. I assume a jumper is next?

Unplug the compressor and let me know if the reading is still present. If so kill the breaker and report back.

Next insert the CT into a spare channel and report back if you see the same 17 watts.

I killed the breaker a couple days ago when troubleshooting and never turned it back on. It's still showing the ~17W. I'll try switching channels and see if things change.

I had a similar problem with a circuit connected to my generators automatic transfer switch. I knew that I should not have had any reading because the legs from the generator are completely isolated from any current or voltage when the generator is not running. I resolved the issue using a jumper for that channel. I have attached a photo that Teken had posted and installed my jumper the same way. One other question, did you remove the CT lead for the GEM channel? If not try that and see if your're still showing the same 17 watts.

Wow, look at those messy wires!
