While the unit is powered, a potentially lethal shock hazard exists inside the case. 

 

 

Remove AC power to the actuator. 

Remove the six screws and the top cover from the actuator case.  See Figure 2.   
Lay extended cover assembly on a flat surface. Remove relay cards if present. 

Reapply AC power to the actuator.   

Press SET UP key to access the INPUT set up group.   

Press FUNCTION key until the lower display reads Direct.   

Press the 

 or 

 keys to set Actuator Rotation direction to CCW.   

NOTE:  Actuator direction must be set to CCW for this procedure.  Direction can be changed 
after calibration is complete.   

Drive the actuator to the 50% position (this refers to the position on the actuator scale for CCW 
rotation).  This should be done manually with the handwheel or with the AUTO - MANUAL 
switch. 

Press SET UP key until the display reads CAL POSOUT.   

Press the FUNCTION key until the dispaly reads DIS CALPOS.    

Press the 

 or 

 keys until the lower display reads BEGN CALPOS.   

Press FUNCTION key.   

The upper display now shows the output of the position sensor in Volts.   

Loosen the allen screw in the hub of the NCS spoiler just enough to be able to rotate the 
spoiler.  See Figure 28. 

Adjust the NCS spoiler so that the voltage in the local display is 2.500 ± 0.010 volts dc.  The 
allen screw should be almost in a vertical position.  The bottom edge of the spoiler should 
almost be horizontal in relation to the NCS PWA. See Figure 28. 

Tighten NCS spoiler set screw with an allen wrench, holding spoilers located on each side of 
the NCS PWA in position.   

:  Spoilers need to be held in position both rotationally and longitudinally along 

the drive shaft extension.  An air gap must be maintained between the surface of the PWA and 
each spoiler.  (Any plastic or paper insulating material may be used to create this gap while 
positioning the spoilers).  Make sure that neither spoiler is touching the sensor PWA when the 
adjustment is complete. 

Press DISPLAY key to exit calibration mode. 

Remove AC power to the actuator.  Reinstall relay cards If present. 

Install a new gasket and replace extended cover.  Secure to actuator with screws.   

Continue with calibration procedure in Table 31.
