Secondary amp meter

[johnsteichen]

Is there any way to add a toroid sensor for a secondary ammeter to follow an auxiliary vacuum pad alternator?

You can use the search feature above to look up "Hall Effect"
Here is a copy of part of the string:

Is there a method to have two ammeters on SV? Pins 24 and 25 are for the primary alternator with the 60 amp shunt. I am running a B&C 8 amp aux alt, can any of the general pins be used for setting up a second shunt?

Check the "What's Next" posts, back at #5, I think. The answer is yes to the exact same question I asked back in October. Now I need to find out what the CS-01 is and how to wire it. Shouldn't be too hard.

"I'm in the planning stage for my panel and would appreciate some kind of time frame estimate for the second amp meter. I would use it to monitor amperage to my e-bus in addition to the standard main bus meter.
Thanks

We slip-streamed multiple AMPS monitoring capability into SkyView recently by adding support of the GRT CS-01 Hall Effect Current Sensor which connects to one of the three enhanced general purpose inputs - Pins 8, 22, or 31. A (one, or more) CS-01 can be displayed on the EMS page in addition to the AMPS Shunt.

Of course, you can also display AMPS on the EMS page that is being generated by the optional VP-X.

why would you need to see both, you can't run both alternators at once is my understanding- i have the aux 8amp b&c alternator as well

I have a double pole switch where I can switch between my main alternator and my back up alternator. In the unlikely event my main alternator fails, my back up automatically takes over and I flick the switch to switch to monitoring its current...

 

[bkthomps]

so wouldn't your regular amp meter show the flow in that case? (mine does...) I don't see the need for an additional monitor

Someone said that you cannot run both alternators at the same time to the same bus. this is not correct. Bill of B & C told me that the main 60 amp alternator runs concurrently with the 20 amp vacuum pad alternator. The aux alternator has its output set at 1 volt below the main alternator. This way, it is just along for the ride until the main alternator quits or is turned off. My volts drops to 13.0v from 13.9v when the main alternator is turned off. this is how you check functionality of your backup prior to an IFR departure. The aux alternator "yellow Lite" lights up when the main is off like.
