NOTE:
If it is desirable for the valve to move to position while setting the default position then
place the selector switch in the "REMOTE" position, else leave the selector in the "OFF"
position to prevent the valve from moving.
1. Connect 4-20mA calibration source to TBM Terminals 52 (-) and 53 (+).
2. Set S2 and S3 to ON (up) position.
3. Apply calibration signal for the desired position (4-20mA or 0-100%).
4. Press either UP or DOWN push button to accept the analog input as the default position.
5. Return S2 and S3 to OFF (down) position.
Calibrate To Limits: (firmware Ver 4.2 and below only, see 4.5.7 for firmware Ver 4.6:
When setup is complete, place selector switch in "Local" mode and stroke valve from
limit to limit for two full strokes. This allows the controller to calibrate the analog position
feedback to the position limits before operation in remote control mode.
