Task 5 Set the zero position
The zero position can be set anywhere within the full-scale range of
the Temposonics sensor.
Stand-Alone:
A. Using the front panel Dial, adjust the Setpoint to move the
actuator to the position you want to assign as zero.
B. Select any control mode that does not use the encoder.
Path: Status > Control Mode
Note If the actuator should move after making the change in control
modes, you will need to reposition the actuator, then change to a
more stable control mode.
C. With the actuator in the desired zero position, click <<Auto
Zero>> button on the Offset/Zero submenu.
Path: Setup > Disp. > Offset/Zero > <<Auto Zero>>
Automated:
1. Adjust the Manual Cmd slider on the Manual Command
window to move the actuator to the position you want to assign
as zero.
2. Use Control Mode on the Control Panel to select any control
mode that does not use the Temposonics sensor.
Note If the actuator should move after making the change in control
modes, you will need to reposition the actuator, then change to a
more stable control mode.
3. With the actuator in the desired zero position, click the Auto Zero
button on the Offset/Zero tab (Inputs panel).
Note When you change the encoder resolution on the Calibration tab, it
immediately changes the resolution of signal values displayed on
the Station Signals, Meters, and Scope windows.
