Belt of the actual value potentiometer for orbital movement 6
• Move the C-arm orbitally into the -95° end position.
• The orbital limit switch on the tube unit side is actuated.
• Loosen the two fastening screws of the actual value potentiometer on the front of the
coupling unit, but do not unscrew them (1/Fig. 23).
• Take the toothed belt off the pulleys.
• Place the new toothed belt on the pulleys.
• Tension the belt: The toothed belt should be tight, but without any mechanical tension.
• Retighten the two fastening screws.
Setting the actual value potentiometer for C-arm orbital movement 6
• The C-arm is in the -95° position. See note.
• Loosen the Allen screw of the large pulley (2/Fig. 23).
• Using a screwdriver, turn the actual value potentiometer counterclockwise to the end
stop (Fig. 24).
• Then turn it clockwise two turns.
• Retighten the Allen screw of the large pulley.
• Perform the mechanical settings as described in the Startup Instructions, Chapter 6.

Only applies to SIREMOBIL Iso-C 3D.
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 yet the case, loosen the Allen screw
of the large pulley before moving the C-arm (2/Fig. 23) to prevent
overturning of the actual value potentiometer.
