3.5.4 Setting Position Limits
This section will advise how to configure end-of-travel limits.
The actuator’s position limits may be set by manual operation or electrical operation.
c
WARNING: If the actuator will not move after setting the limits, the limits have been set incorrectly.
Set Close Position Limit (Handwheel Operation)
1. Enter the “SETUP” mode as detailed in Section 2.1.3, Entering the Setup Mode.
2. Enter “POSITION SETUP?” routine.
3. From the “SET CLOSE POSITION LIMIT?” display, select “YES.” “CLOSE VALVE OK?” will be displayed on the LCD.
4. Engage manual override as detailed in Section 3.6.1, Manual Operation.
5. Ensure that the valve is fully closed.
6. Move the valve in the open direction for one handwheel turn to allow for coasting of the motor.
7. When the valve is positioned correctly, select “YES” again. The LCD will display “SAVE CLOSE LIMIT OK?”
8. Select “YES.”
The close position limit is now calibrated. Check the position limit setting as follows:
1. Move the valve in the open direction. The close lamp should extinguish with approximately one turn of the
handwheel.
2. Move the valve back in the close direction and check that the close lamp illuminates just before the full close posi-
tion is reached (approximately ½ to 1 turn).
3. Select “YES” at the “SET OPEN POSITION LIMIT?” prompt.
4. Set Position Precision? The QX permits position to be reported to the User in either default mode of XXX% OPEN,
or single precision mode of XXX.X% OPEN. This may be preferred in Modulating or other positioning applications
such as network move-to, analog fail move-to, communication loss move-to, or ESD move-to.
