To adjust the bumper sensitivity, proceed as follows:
1. Ensure that the pedestal is fully prepared with the payload correctly fitted and
balanced. Power up the pedestal.
2. Check the sensitivity of the bumper sensors by tapping the bumper lightly. The
bumper manual reset [11] illuminates when the sensors have detected a collision.
3. To change the sensitivity of the bumper, remove the plastic cap covering the
bumper sensitivity potentiometer [13] and using a small screwdriver adjust the
potentiometer. Turning the potentiometer clockwise increases bumper sensitivity
and turning the potentiometer anti-clockwise will decrease bumper sensitivity.
4. Repeat steps 2 and 3 until the correct adjustment is made.
5. To commence operation of the pedestal, press the bumper manual reset [11] on the
pedestal and then re-initialise the pedestal from the control panel.
Consult the relevant Vinten Radamec Control System Operators Guide for more information on
re-initialising the pedestal.
Referencing the studio datum position (FP-188 only)
To maintain positional accuracy for an FP-188 pedestal within the studio, it is necessary to
periodically reference the absolute datum—a target permanently fixed to the studio floor. For
instructions on how to reference the studio datum, consult the relevant VRC Operators Guide.
