Place selector switch in “OFF” position before calibrating actuator
Calibrate Analog Input (Position Command Signal)
1) Connect 4-20mA calibration source to TBM Terminals 52 (-) and 53 (+).
2) Set S1 to ON (up) position. Apply 4mA zero calibration signal and then press DOWN push button.
3) Apply 20mA full-scale (span) calibration signal and then press UP push button.
4) Return S1 to OFF (down) position.
NOTE: When S1 is ON, the analog input signal is fed to the analog output. A current meter may be
connect to TBM terminals 50(-) and 51(+) to monitor the analog input at the output.
Calibrate Analog Output (Position Feedback)
1) Connect calibrated 4-20mA meter to TBM Terminals 50 (-) and 51 (+).
2) Set S2 to ON (up) position.
3) Press UP or DOWN push button to increase or decrease zero (4mA) analog output signal.
4) Return S2 to OFF (down) position.
5) Set S3 to ON (up) position.
6) Press UP or DOWN push button to increase or decrease full-scale (20mA) analog signal.
7) Return S3 to OFF (down) position.
Select Modulation Delay Time
1) Set S1 and S2 to ON (up) position.
2) Press UP push button to select 3-Phase motor (Modulation delay = 2 seconds)
3) Press DOWN push button to select 1-Phase motor (Modulation delay = 12 seconds)
4) Return S1 and S2 to OFF (down) position.
Enable/Disable Go-To-Position on Loss of Signal
1) Set S4 ON (up) to Enable Go-To-Position on loss of signal.
2) Set S4 OFF (down) to Disable Go-To-Position on loss of signal, i.e. Stay in last position on loss of
signal.
Set Default Position (Position of valve on loss of analog input signal when S4 enabled)

:
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:
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.
