HS-105P, PE. SA AutoCam™ Pan & Tilt Head - Vinten Radamec

HS-105P Installation
Zoom
The anti-backlash gear on the zoom pot is meshed with the zoom motor gear. To
rotate the pot shaft, loosen screw “B” and slide the pot gear out of mesh.
1. Loosen fixing screw “B” sufficiently to allow the zoom pot gear to rotate
free of the zoom motor gear, if required.
2. Measure the resistance of the zoom pot pin #3 with respect to the wiper.
Rotate the lens barrel to the end of travel in the telephoto direction - the
resistance should decrease. Lift the pot anti-backlash gear out of mesh and
rotate the gear for a resistance of 300 ohms. Re-engage the pot with the
motor gear, advancing the ant-backlash gear by 2-3 teeth.
3. Connect the resistance meter to pin 1 with respect to the wiper. Rotate the
lens barrel to the end of travel in the zoom wide direction - the resistance
should decrease. Check that the resistance is approximately 300 ohms.
Repeat steps 2 and 3 until the resistance readings at each end of lens travel
are the same.
4. When symmetry is achieved, check that the anti-backlash gear is set correctly
and tighten the fixing screw “B”.
