3.4 Commissioning
3.4.1 Commissioning procedure
1. Turn on the air supply to the positioner.
2. Turn on the electrical power supply to the positioner.
Apply the 4...20 mA signal to the analog input (terminals +11/-12).
3. Check for proper mounting:
-
Press and hold
adjustment within sensor range) is indicated, then release
-
Press
and note the values. The angle of rotation is indicated in degrees.
For quick motion: Press
Recommended range:
between -28° and +28° for linear actuators
between -57° and +57° for rotary actuators
Minimum angle: 25°
4. Run the standard autoadjustment function.
Note:
The standard autoadjustment function is only available with software revision
level 2.XX and higher.
For linear actuators:
-
Press and hold
-
Press
-
Then release
Standard autoadjustment is started.
or
For rotary actuators:
-
Press and hold
-
Press
-
Then release
Standard autoadjustment is started.
When the autoadjustment function is finished successfully, the parameter settings
are automatically saved and the positioner returns to operating mode 1.1.
If standard autoadjustment should fail, the procedure is automatically interrupted,
and an error code is indicated. In this case press and hold
3 seconds. The positioner returns to mode 1.3 MAN_SENS (manual adjustment
within sensor range). Check the assembly for proper mounting and, if required, read-
just it. Repeat the standard autoadjustment function.
5. If required: Adjust the dead band and tolerance band
This step is only necessary for critical actuators, e.g. very small ones. Usually,
it can be skipped.
1.
The zero position is automatically determined and saved by the standard autoadjustment function:
turning counter-clockwise (CTCLOCKW) for linear and clockwise (CLOCKW) for rotary actuators.
