Badger Meter SRD/SRI Valve Positioners - Manual (Page 49)

Menu 2: Autostart
M 1 2 3 4
½ - ½ - - M and LED 2 flash
Selection between different Autostart modes
(change with key UP or DOWN):
Autostart:
To automatically adapt the positioner to the valve. Geometric data of the
actuator is determined and optimally assigned to control parameters. If the
"Standard" Autostart does not result in stable regulation, another Autostart
mode - depending upon actuator - should be selected. At
initial start-up,
an Autostart should always be performed.
Attention: Autostart overwrites previous control parameters!
2.2 Ready for "Standard" Autostart:
- 1 - - 1 LED 1 and LED 4 lights up
With key UP or DOWN to other Autostart modes:
2.1 Ready for "End points" Autostart:
Serves for automatic adjustment of the SRD to the mechanical end points.
- - 1 1 - LED 2 and LED 3 lights up
2.3 Ready for "Enhanced" Autostart:
To the optimization of the controller parameters in relation to standard mode:
- - 1 - 1 LED 2 and LED 4 lights up
2.4 Ready for "Smooth response" Autostart:
Extended, damped controller parameters for e.g. smaller drives
- 1 - 1 - LED 1 and LED 3 lights up
2.5 Ready for "Fast response" Autostart:
Extended, undamped controller parameters for e.g. larger drives
- 1 1 - - LED 1 and LED 2 lights up
W A R N I N G
To avoid any personal injury or property damage from sudden or fast
movement, during autostart:
Do not put your finger or other part at any time inside the valve or in
any moving part of the actuator. Do not put your finger or other part
at any time in the feedback lever mechanism. Do not touch the rear
part of the positioner at any time.
After selection and start (by pressing the UP+DOWN keys) the function
taking several minutes can be followed at LCD or the green LEDs.
Duration on a valve position can take some time depending on actuator
volume, air supply, pressure, etc.
- 1 - - - LED 1 lights up
Moving direction, mechanical starting and ending positions are determined
by one or several passages of valve position range.
- - 1 - - LED 2 lights up
Ramps are entered and control system parameter is determined (ratio
position/valve size).
- - - 1 - LED 3 lights up
Jumps are entered for determination of control parameters.
- - - - 1 LED 4 lights up
Determination of positioning speeds.
- - - - - All LEDs are off
Determined values are saved; previous values are superscribed. The
SRD is IN SERVICE again with the detected new parameters.
