not closed to a proper position.
(2) The switch no. 30 is not energized.
1: Used for starting cooler.
2: When the indication lamp lights on, it means the cooler
is running.
1: Used for stopping cooler.
2: When the indication lamp lights on, it means the cooler
stops.
When the selection switch (30) is set at demagnetizing
position, magnetism will release according to the setting
time. Turn the regulator clockwise for increasing
demagnetizing time.
(The bigger working area, the longer release time. The
smaller working area, the shorter release time).
When the selection switch (30) is set at demagnetizing
position, the lamp will flash according to the time set by
the regulator (28).
(When flash stops or the lamp does not light on, it means
magnetism release is finished).
When the selection switch (30) is set at magnetizing
position, the workpiece will be sucked by the setting
magnetism. Turn the regulator clockwise for increasing
magnetism. (A workpiece with bigger area requires less
suction force. A workpiece with smaller area requires
more suction force. Use your hand to push the workpiece
for checking if it is held securely or not).
When the indication lamp lights on, it means magnetizing
is performing.
1: When turning this selection switch to demagnetizing
position, magnetism will be released according to the
time set by the regulator (28).
2: When turning this selection switch to magnetizing
position, the workpiece will be sucked according to the
time set by the regulator (29).
* The hydraulic system circuit for table longitudinal feed is
interlocked by the magnetizing switch and the
longitudinal throttle valve.
