Efka Variocontrol V820 - Signal Output Position; Signal Output 512 Impulses Per Rotation; Actuator

EFKA DA82GA3312
50
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.
