IV - 2 Mechanical adjustment of the operating time
Mechanical adjustment of the operating time is carried out in the factory to obtain the best accuracy/speed
compromise for the positioner.
Mechanical modification of the operating times could prevent the positioner from operating correctly.
After making these modifications, it is essential to perform autocalibration.
Opening and closing times of at least 0.5 s must be respected for autocalibration to be carried out correctly.
The valve operating time can be adjusted using the adjustment screws located on the side of the base, beside the
exhaust hole. Adjustment is carried out directly with a 4 mm flat screwdriver.
Procedure :
- Adjust the adjustment screws depending on the type of actuator used.
- Use MANUAL operation to test adjustment of the operating time (MANUAL mode: see § VII - 3 - 2).
- Restart autocalibration (see § VII - 2)
For information, the following minimum operating times can be obtained:
(reducing the operating time may impair the positioning accuracy)
