You don't, the EIS-4000 does not accept shunts. The 

EIS-4000 can use 0 to 5 volt input to the aux inputs. Any 

attempt at directly connecting the shunt to the EIS-4000 

will likely cause permanent damage to the instrument. 

   

  With that said as I mentioned on VAF forum you need a 

hall effect. If you want multiple current measurements you 

need an additional hall effect current sensor. The hall effect 

is connected to one of the AUX inputs. I can help you setting 

the EIS-4000 up when you get your hall effect. You will need 

to set the scale factor and off-set. If you purchase a hall 

effect from GRT they provide instructions. If you have a Q email me.

   

  Cheers George

I am building and RV9A using the Z-14 diagram as a start.  

Also installing EIS-4000.  How do I go about getting a load 

reading from the shunts into the EIS?



Make your reply really detailed,  I am a newbie!!!



Thanks, Duane

I wondered about this so off I went to the GRT site. At:



www.grtavionics.com/model_4000&6000.htm



I found:



"Functions :

..

        * 6 Auxiliary Inputs user configurable can provide: 

..

            * Ampmeter"  <<<<<<<<<<<<<<

To monitor the voltage drop across a shunt you need a differential

(double-ended) input to the analog/digital converter. Since the manuals for

the EIS 4000 are not on-line I don't know if it has any.



I'm using a Honeywell CSLA1CE Hall effect sensor. I believe both Blue

Mountain Avionics and Advanced Flight Systems use a part from the same

family.

That's the best solution:  send $60 to GRT and get their current sensor,

which also comes with some instructions.  Then just change your diagram

from showing shunts to showing the current-carrying wire passing through

the GRT "loop" current sensor.  In some ways, it's easier to install

than a shunt . . .
