Manual Valve Stroke to override of Input Signal using On-Board Pushbuttons (Stro)
This menu gives access to the following three stroking functions via the pushbuttons:
1.
Adjs
- Adjustment of positioner to any position using the pushbuttons
2.
OP
- Open, sets the valve to the full open position
3.
CLs
- Close, sets the valve to the full closed position
These functions set the positioner to digital control mode (
network independent
) and therefore allow override of
the network setpoint control signal.
The positioner has a feature which allows the operator to override the analog setpoint signal and change valve
position from the pushbuttons. This is done from the
Stro (Manual Override-Stroke Menu).
Enter calibration as
described in Section 8.9.3 and use the “Down” button to cycle to the
Stro
menu.
Enter this menu and control the position of the valve.
