ADJUSTING THE PAN/TILT DAMPERS
Re-adjustment of the Pan or Tilt dampers is necessary if the end-stop adjustments have
caused either of the motors to slide along its axis at any time.
Loosen the dampers marked (F1) and (F2), See Figure 4, until the spring-loaded plastic
pin is not touching the motor. Using the controller, set the Pan/Tilt speed to minimum and
turn the lamp on. Then, still using the controller move the mirror from, either extreme left
to extreme right for Pan adjustment, or, extreme top to extreme bottom for Tilt
adjustment. Whilst the mirror is moving watch the beam movement to ensure that it is
smooth. Tighten the dampers (F1) and (F2) until the smoothness of the mirror movement
is affected and it becomes more ’twitchy’. At this point you should turn the dampers
slightly back so that you restore the full smoothness of the mirror movement.
If the dampers are set to a position that is too loose you will find that the mirror will lose
steps when running at the higher movement speeds.
If the dampers are set to a position that is too tight you will find that it will affect the
smoothness of the mirror movement at the lower movement speeds.
