B.2.4 Switches
The short seam automat is equipped with three different
types of switches:
•
Emergency switch for stopping a sewing program,
• supply switches for current and vacuum,
• control switches for controlling the machine operation.
Emergency switch
Program stop switch
When the program stop switch 1 is pressed, all ma-
chine movements and the sewing process are stopped
immediately.
The switch engages when pressed. Rotating the switch
in the clockwise direction will unlock the switch, and it
moves back to its original position.
The control program performs a reset.
When the footswitch is depressed, the machine moves
to zero position and is then ready for operation again.
Supply switches
Main switch
The main switch 2 is used to turn the power supply
of the machine on or off. For safety reasons, the machine
must be turned off using the main switch when it is stan-
ding still for an extended period; in this case, all functional
units are deactivated. The main switch also serves as
an additional emergency off switch.
Vacuum switch
The vacuum switch 3 is used to switch the vacuum
supply of the aspiration system on and off.
Control switches
Footswitch for bundle clamp
When this footswitch 4 is depressed, the bundle
clamp opens. When the switch is released, the bundle
clamp closes.
Footswitch for machine operation
This footswitch 5 is used to control the operating
steps of the SHORT SEAM AUTOMATE and to start the
fully automatic machine operation.
