Adjusting the Mirror
Readjusting the mechanical stop on the RoboScan Pro 518 mirror adaptor is required if the
pan or tilt motor occasionally loses step, leaving the mirror incorrectly positioned after a
reset. This error occurs when the recoil of the mechanical reset bounces the mirror and
bracket a whole pan or tilt motor step.
P a n A d j u s t m e n t
1.
Connect the RoboScan Pro 518 to a controller and set the address. Switch on
the controller and then the fixture.
2.
Use the controller to move the mirror to the extreme left position, thus
positioning screw A1 at the upper mechanical stop (A2).
3.
Release the lock-nut on adjustment screw A1.
4.
Turn screw A1 clockwise 1/2 - 1 turn to increase the distance between the
head of the screw and the mechanical stop (A2).
5.
Tighten the lock-nut on screw A1.
6.
Reset the fixture a number of times to check the new reset position.
7.
Use the controller to move the mirror through all extreme positions,
checking that adjustment screw B1 does not touch mechanical stop B2.
during these steps. If it does, then adjust screw B1 accordingly.
T i l t A d j u s t m e n t
1.
Use the controller to move the mirror to the upper-left position until the top
mechanical stop (C1) is positioned at the edge of the mirror bracket (C2).
2.
Loosen the 2 set crews (E) holding the motor axle while taking care that
the motor does not slide vertically from its current position.
