Setting the actual value potentiometer for C-arm orbital movement 0
NOTE
Prior to setting the actual value potentiometer the C-arm
must be in the orbital -95° position (the orbital limit switch on
the tube side is actuated). If this is not the case, loosen the
Allen screw of the large pulley before moving the C-arm
((2/Fig. 47 / p. 130)) to prevent overturning of the actual value
potentiometer.
x The C-arm is in the -95° position. See note.
x Loosen the Allen screw of the large pulley ((2/Fig. 47 / p. 130)).
x Using a screwdriver, turn the actual value potentiometer counterclockwise to the end
stop ((Fig. 48 / p. 130)).
x Then turn it two turns in a clockwise direction.
x Retighten the Allen screw of the large pulley.
x Perform the mechanical settings according to the Startup Instructions, Chapter 6.
