which provides 24 VDC and ground return to focus motor A2A1. With +24 VDC and ground return, the focus
motor moves the focusing mechanism attached to the xenon lamp in or out. Setting VARIABLE BEAM WIDTH
switch A3S2 to the up position pr24 VDC to terminal 3 and ground return to terminal 1 of DC focus
motor A2A1 driving the focusing mechanism in one direction. Setting VARIABLE BEAM WIDTH switch A3S2
to the down position re24 VDC and ground return to the terminals 1 and 3 of focus motor A2A1
thereby reversing the direction of focus motor and the focusing mechanisms.
