4 INSTALLATION
WARNING
This product is intended for industrial use. In a domestic environment this prod -
uct may cause radio interference. It is the users responsibility to take adequate
precautions.
4.1 Termination resistance
The termination resistance must be connected to the ends of the CAN bus to prevent
communication problems.
The controller has a built--in terminator, but the power source and wire feed unit do
not.
The terminator should be fitted as follows depending on how the units are
connected:
1. Controller con n ected to wire feed unit.
The termination resistance must be con-
nected to the rear of the power source.
(Already connected this way on delivery).
2. Controller connected to power source.
The termination resistance
must be connected to the front
of the wire feed unit.

5OPERATION
The wire feed speed and voltage
The wire feed speed and voltage can be adjusted using the PUA1 controller in set and
measure modes. If you want to use the potentiometers on the front of the wire feed unit
then the toggle switch inside the wire feed unit must be in the upper position and the
PUA1 controller should be set for remote operation.
Remote control
To use a remote control, the toggle switch inside the wire feed unit m ust be switched
to remote, and the PUA1 controller must also be set to remote, as above. If you want
to change the wire feed and voltage parameters using the controller, you must switch
from “remote“ to measure mode or set mode.
