Manual initialization of linear actuators
You can use this function to initialize the positioner without needing to move the actuator to
the end stops. The start and end positions of the actuator travel are set manually. When the
control parameters are optimized, the further initialization process runs automatically.
The following requirements must be fulfilled before activating manual initialization:
1. The positioner has been prepared for using on linear actuators.
2. The actuator spindle can be moved completely.
3. The displayed potentiometer position is within the permissible range between "P5.0" and
"P95.0".
Initializing the linear actuator automatically
1. Switch to the "Configuration" mode. To do this, press the button for at least 5 seconds
until the display shows the following:
2. Call the "2.YAGL" parameter. To do this, briefly press the
button. The following is
shown on the display depending on the setting:
3. Check whether the value displayed of the "2.YAGL" parameter matches with the setting
of the transmission ratio selector. If required, change the setting of the transmission ratio
selector to 33° or 90°.
