Start Cycle
Operating the start button (78 b, fig. 11) moves
the switch lever assembly (212) towards the
main cam initiating the following sequence:
a) The set screw (208) of the switch lever
assembly (212) turns the switch arm (125)
mounted on the grooved shaft (183). The
rocker assembly (91, fig. 2) moves the drive
wheel (86, fig. 2) into contact with the motor
pulley and turntable by means of a tension
spring. At the same time the switch slide
assembly (117, fig. 7) actuates the line
switch through the switch arm and the
turntable begins to turn.
b) The switch spring (UF) mounted on the
switch lever assembly (212) is brought within
range of the cam follower lever (143) so
that it is pushed into the change position
after the rotation of the main cam.
Operating the start button also releases the
start lever (216) pulling it towards the main
cam by means of the tension spring (213). This
causes the coiled spring (184) to bring the
shut-off lever (136, fig. 14) within range of
the main cam dog. Thus the shut-off lever drives
the main cam.
To prevent mis-operation, the start button is
locked during the start cycle (i. e. when the
main cam is turning). Just before the main cam
reaches its null position (at the end of the
change cycle), the start lever is pushed clear
of the main cam by means of the start pin (SB)
of the main cam. This, in turn, restores the
switch lever and start button to their original
positions.
After installing and also after moving the record
changer, the unit should be operated with the
tonearm locked. This will automatically re-
adjust the shut-off lever which may have shifted
out of position.
Manual operation
Placing the switch button in “Manual” position
initiates the start cycle. The switch lever
assembly (212) is pushed towards the main
cam and the following sequence is set up:
a) Set screw (208) mounted on the switch lever
(212) rotates the switch arm (125) which is
mounted on the grooved shaft (183).
b) The rocker assembly (91, fig. 4) then moves
the drive wheel (86, fig. 2) into contact with
the motor pulley and turntable by means of
a tension spring.
c) At the same time, the switch slide (117,
fig. 7) actuates the line switch and the
turntable begins to rotate.
d) The switch arm latch (179) rests in the
support (BG) in the base plate, locking the
switch arm in position to’keep the drive
wheel in contact with the turntable.
