4.5 Exiting Calibration
To exit calibration mode and return to normal operation use the up arrow key as follows:
• If the positioner is at Menu level in the calibration, as determined by LCD displaying a
Menu name only (MCAL, etc.), press the up arrow key once to exit CAL mode.
• If the positioner is at function level in the calibration, as determined by LCD displaying a
function and Menu name only (MCAL Lo, etc.), press the up arrow key once to enter the
Menu level and once more to exit CAL mode.
• When the calibration mode is exited the Menu and function names will no longer be dis-
played by the LCD. The LCD will be displayed “OK”.
Exiting can not be done during a calibration procedure. When a calibration function is initiated,
the user must wait until the function’s calibration is complete before being able to exit calibration.
The up arrow key can be used, as described above, to move to the Menu level and then to exit
CAL mode.
4.6 Manual Override of Input Signal (Via On-Board Keypad)
The positioner has a feature which allows the operator to override the analog signal and change valve
position from the keypad. This is done from the Stro (Manual Override-Stroke Menu). Enter calibra-
tion as described in section 4.1 and use the down arrow button to cycle to the Stro menu. Enter this
menu and control the position of the valve as shown below.
