Remote control adapters RAC 12 and RAC 23
The cable-mounted adapters, RAC 12 and RAC 23 are not sold any more, they are
replaced by the adapters RA 12 and RA 23.
This description applies to remote control adapters connected to
Aristo welding equipment with control panel A2, A4, T4, T6, M2,
MA4, MA6 or U6. When the AristoPendant U8 is used, the functions
are different, see page 15.
The remote control adapters operate correctly with any software version for the control
panels A2, A4, T4, T6, M2, MA4, MA6 or U6.
There is one adapter for remote units with 12 pole connector (RAC 12) and one for units
with 23 pole connector (RAC 23). The only difference between the adapters is the
connection to the remote control.
The remote control adapter has a software identity, machine ID. The ID defines how the
welding equipment reacts on the commands from the remote control. When starting up the
equipment the MMC unit sends a request for the ID, this adapter has ID 1.
The adapters have a built-in terminating resistor. This resistor can be disconnected by
removing the jumper from terminal J1 on the CAN adapter board. See the component
position diagram on page 14. In most connection cases the resistor has to be disconnected,
see page 4.
When a remote control unit is used to set the voltage, the function will be changed to the
setting of current during MMA and TIG welding.
When carrying out TIG welding in pulse mode, the value of the pulse current can be
changed with the remote control.
