First Start
Calibrate in the basic menu is displayed automatically the fi rst time the positioner is con-
nected, and can be selected from the basic/main menu at any later time.
A complete calibration takes about three minutes and includes end limit calibration,
auto-tuning, leak test, and a check on the speed of movement. Start the automatic cali-
bration by selecting Auto-Cal and then answer the questions on the display by pressing
OK or the respective arrow. The menu is described later in this section.
Calibration Error Messages
If a fault occurs during the calibration, one of the following error messages will be
displayed:
Invalid movement/press ESC to abort
No movement because the air is incorrectly connected, for example. After the fault is
corrected, the calibration sequence must be restarted.
Pot unaligned/press ESC to abort
The potentiometer has been set to an illegal value. The potentiometer is aligned using
the Calibrate - Expert cal - pot Menu. The calibration sequence must be restarted after
the fault is corrected.
Air leak detected/ESC = abort OK = go on
An air leak has been detected. The calibration sequence should be restarted after the
fault is corrected.
Increase C- damper/ESC = abort OK to retry
Increase C+ damper/ESC = abort OK to retry
C+
(C–)
Clockwise Increased damping/Less flow
CCW Decreased damping/More flow
NOTE: Too much increased damping (low flow)
might cause irregular actuator function.
3 revs CCW Maximum flow
