APPENDIX E: Addendum for 4-20 mA Option
GENERAL INFORMATION
Some models provide a passive analog 4-20 mA output on two terminals. These terminals are
covered in Chapter 2
The output tracks the weight displayed on the indicator, so you must first have the indicator
configured and calibrated correctly in order for it to work properly.
Here is a working connection diagram used at the factory to test:

24 VDC
R = 250 ohms

4-20A or AA

NOTE 1
: In your application, substitute the actual input device for R
L
. If your input device is
polarized, connect the common lead to the negative lead of the 24 VDC power supply and the
positive lead to the BB (4-20B) wire.
NOTE 2
: The AA (4-20A) and BB (4-20B) wires are not polarized. You may connect them in any
manner you wish.
