INTRODUCTION
The remote controls and adapters are designed for ESAB's welding equipment with CAN
bus communication.
When the remote control or adapter is connected to the welding equipment, the control
panel is in remote control mode, the buttons and knobs are blocked. The functions can only
be adjusted via the remote control unit.
If the remote control unit is not to be used, it must be disconnected from the welding
equipment, otherwise the equipment will remain in remote control mode.
For more information about the operation of the remote control unit, see the operating
instructions for the control panels.
Only one remote control or adapter may be connected to the welding equipment.

DESCRIPTION OF OPERATION
Terminating resistors
In order to avoid communication interference, the ends of the CAN bus must be terminated
by resistive loads.
The CAN remote controls and CAN 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 positions diagrams on pages 12 and 14.
To check if the terminating resistor of the CAN remote control or CAN adapter is connected:
measure the resistance between pin 3 and 4 of the 4 pole panel plug, or pin L and K of the
12 pole cable plug. The resistor is connected if the resistance is about 120 ohm.

Remote controls
The remote controls have 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.
The remote controls are delivered with the correct machine ID. Spare part boards are
delivered without machine ID. To read or change the machine ID you need the
ESAT service kit, see page 17.
The control panel of the equipment must have correct software version in order for the
remote control to function correctly. See the specifications for each remote control.
The remote controls have a built-in terminating resistor. This resistor can be disconnected
by removing a jumper from terminal J1 on the CAN adapter board. See the component
position diagram on page 12.

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.

SERVICE INSTRUCTIONS
What is ESD?
A sudden transfer or discharge of static electricity from one object to another. ESD stands for
Electrostatic Discharge.
How does ESD damage occur?
ESD can cause damage to sensitive electrical components, but is not dangerous to people.
ESD damage occurs when an ungrounded person or object with a static charge comes into
contact with a component or assembly that is grounded. A rapid discharge can occur,
causing damage. This damage can take the form of immediate failure, but it is more likely
that system performance will be affected and the component will fail prematurely.
How do we prevent ESD damage?
ESD damage can be prevented by awareness. If static electricity is prevented from building
up on you or on anything at your work station, then there cannot be any static discharges.
Nonconductive materials (e.g. fabrics), or insulators (e.g. plastics) generate and hold static
charge, so you should not bring unnecessary nonconductive items into the work area.
It is obviously difficult to avoid all such items, so various means are used to drain off any
static discharge from persons to prevent the risk of ESD damage. This is done by simple
devices: wrist straps, connected to ground, and conductive shoes.
Work surfaces, carts and containers must be conductive and grounded. Use only antistatic
packaging materials. Overall, handling of ESD-sensitive devices should be minimized to
prevent damage.
CAUTION !
STATIC ELECTRICITY can damage circuit
boards and electronic components.
S Observe precautions for handling electrostatic-
sensitive devices.
S Use proper static-proof bags and boxes.

Service aid
We can offer a number of service tools that will simplify the service.
Antistatic service kit
Ordering no. 0740 511 001
The kit makes it easier to protect sensitve
components from electrostatic discharge.
Contents:
S A conductive mat (size 610 x 610 mm)
S A 1.5 metre long ground cable with a
crocodile clip
S An adjustable wrist strap and cable with
an inbuilt protective resistor
Antistatic service kit
ESAT service kit
The software update is made from a PC, it has to be managed by a trained serviceman. For
this a PC program called ESAT, ESAB Software Administration Tool, is needed. The PC is
connected to the welding equipment by a cable connector and a CAN reader. From the
ESAT it is possible to update the software. ESAT also contains service functions by which it
is possible to control, change or read the different functions of the equipment.
For the installation and use of the ESAT you need a PC with operating system Windows.
The ESAT service kit contents:
S CAN adapter with connection cables
S CD with software
S Instruction manual for ESAT
