AVID SmartCal valve positioner

Installation & operating instructions

Appendix C - Setting the transmitter output fail current

The SmartCal conforms to Namur NE43 with an operating current of 3.8 mA to 20.5 mA. Input 
currents between 3.2 mA and 3.5 mA and above 21.0 mA are considered outside the control range 
and are a current input failure. When the input current is out of range the LCD will display a failure 
message and the transmitter output (if so equipped) will go to pre-determined current to indicate 
the failed state. The transmitter output can be configured to go to 3.4 mA or 21.1 mA by the user.

To set the transmitter output:
Step 1: Remove enclosure cover. Follow appendix B to remove the electronics cover.
Step 2: For 3.4 mA fail current place the jumper in the L position on the LCD pcb. Note this is the 
default factory position. For 21.1 mA  fail current place the jumper in the H position on the LCD pcb.
Step 3: Replace electronic canister cover and enclosure cover.
