6.30 Signal Output Position 2
Transistor output with open collector
Signal whenever the needle is in the slot between position 2 and 2A
Independent of sewing, thus also when turning the handwheel manually
Suitable e. g. for the connection of a counter
An inverted signal is issued at socket B/8
6.31 Signal Output 512 Impulses per Rotation
Transistor output with open collector
Signal whenever a generator slot of the position transmitter is sensed
512 impulses per rotation of the handwheel
The impulses are issued independently of sewing, thus also when turning the handwheel manually
Suitable e. g. for the connection of a counter
An inverted signal is issued at socket B/7
6.32 Actuator
The commands for the sewing operation are input by means of the actuator, which is connected to the pedal. Instead of the
built-on actuator a different actuator can be connected to socket B80.
