Calibrate Position Sensor
ATTENTION
The Position Sensor is factory calibrated to a full span, 90 degree rotation. Under
normal operation, the position sensor does not require calibration.
NOTE: Before you perform a calibration of the position sensor, it is recommended that you first verify the
voltage output from the sensor PWA. See " Position Sensor Operation " in section 5 for the procedure.
Position sensor calibration may be necessary due to any of the following conditions:
•
The sensor PWA output is incorrect,
•
The sensor Printed Wiring Assembly (PWA) in the actuator has been replaced,
•
The sensor spoiler adjustment has been disturbed.
When the position sensor PWA has been replaced (or serviced), you should perform a calibration of the
sensor circuit and then store it as the motor factory calibration. Please note that performing this procedure
will destroy any previously stored motor factory calibration values. Table 27 outlines the steps to perform a
calibration to the NCS circuit.
WARNING
While the unit is powered, a potentially lethal shock hazard exists inside the case.
