The switches have been factory-set as shown above
at the time of delivery.
SW1 Continuous cycle mode
Buttons are continuously sewn by keeping the pedal depressed. Refer to the next page and beyond for the detailed
description of the sewing machine operating intervals and the length of time during which the machine performs fine
positioning of a button.
SW2 Double-stepped action of the button clamp
Depress the pedal to its middle position to make the button clamp come down. This function is used in this state to
automatically raise the button clamp by returning the pedal to its home position. The sewing machine starts running when the
pedal is fully depressed.
Refer to the next page and beyond for the detailed description of the timing at which the button carrier moves after the
operation of the sewing machine and the time during which the machine performs fine positioning of a button.
SW3 Adjustment mode
This function is used to make each of the driving sources independently actuate in combination with the operation switches.
Under this mode, the indicator of "ALM No." indicates ON/OFF of sensors using the numbers and the like corresponding to
the respective sensors.
SW4 Action without button
The button detecting sensors are ineffective, and the functions of the sewing machine excluding the button feeder are
operative. This function is used to check the performance of the sewing machine. (Do not place a button on the sewing
machine.)
(Caution) To change the functions of the sewing machine by changing over the setting of DIP switch ❸ and digital
switches ❹ and ❺ , turn OFF the power to the machine first, change the switch setting and turn ON the
power to the machine. Change over the setting position of DIP switches between ON and OFF without fail.
