Detailed description of
functions from the program
selector switch
Ultrasonic devices are used in a wide range
of fields today, so that users have a variety of
different control requirements. A welding in-
stallation needs to be able to be connected to
the available peripheral devices.
For this reason, a number of programmes
have been created to suit the most common
peripheral requirements. These programmes
are permanently installed in an integrated
computer and can be preselected via rotary
switches.
The program selector switch is deliberately
located on the card module (see fig. 4a)
inside the housing in order to prevent un-
authorised changes to the program.
8.2.1 Before changing a program
1. Disconnect the device from the power
supply.
2. Unscrew the 4 fastening screws (33).
3. Take out the generator module by
pulling the grips (26).
