1.
Remove the SU-S from the backplate and verify nothing is mechanically preventing movement
(see previous ”Obstructed interceptor blade movement”).
2.
Examine the behavior when powering up the SU-S. Replace the SU-S if the motor do not operate
at all (there should be more than just a ‘click’ sound – compare with a functional SU-S).

1.
Remove any obstacles (growth, dirt, mud, paint etc.) that prevents the interceptor blade to fully
retract.
2.
Check and verify the SU-S is mounted with the screw shaft nut and the backplate connecting rod
fitted correctly (see illustration below).
3.
If the screw shaft nut do not retract from the outmost position when the SU-S is removed from
the backplate, then free the screw shaft nut by using a torx screwdriver at the shaft end to gently
rotate the screw shaft just enough to free the nut from the end stop. Connect the SU-S to the
distribution unit and let the motor retract the screw shaft nut to the inner position.
