Why can't the values on the SC200 4-20 mA output expansion module be adjusted (reads +0 only)?
Summary
When setting up an analog 4-20 mA Output Expansion Module for SC200, Catalog Number/ Order Code 9334600, ACTIVATION values cannot be changed if the modules and sensors have been installed out of order. The activation value stays at "+0" and cannot be changed. The units are often wrong also.
Answer
If this problem of not being able to change the ACTIVATION values on the 4-20 mA Output Expansion Module for SC200, SC200 controller needs to be restarted. This can be easily done  by removing power or go to MENU>TEST/MAINT>RESTART sc200. The problem happens when the module or a new sensor has been added without restarting the SC200 controller.
