EQUIPMENT DESCRIPTION
Arc-WorldLite 50 System Manual 3-10 MOTO MAN
3.6.1 Arc Shields
WARNING!
Although the arc curtain blocks dangerous arc radiation, never look
directly at the arc without protective eye wear!
Two separate arc screens are used on the Arc-WorldLite 50. The first is the metal
arc screen on the front of the weld table. These screens block arc radiation and
sparks from the welding operation. The material used to cover the back of the
robotic cell acts as the second arc screen. This material reduces the amount of
ultra-violet radiation that escapes from the robotic cell.
3.6.2 Fencing
The safety fencing provided with the Arc-WorldLite 50 system encloses the entire
robotic cell. It forms a physical barrier preventing entry into the robot envelope
during automatic operation.
3.6.3 Emergency Stops (E-STOPS)
In addition to the safety features described above, the Arc-WorldLite 50 has
strategically placed E-STOPS. These are operator actuated devices that, when
activated, immediately stop all system operation. Brakes are applied to the robot
and all servo power is removed from the system. The system E-STOP lights come
on and all positioner motion is stopped. The following is a list of their locations:
• The playback panel on the controller has one E-STOP button.
• The programming pendant has one E-STOP button.
• The operator station has one E-STOP button.
3.6.4 ENABLE Switch
The ENABLE switch is a safety feature which controls servo power while in
TEACH mode. When pressed in, this switch allows the operator to turn servo
power ON and initializes the system. However, should the operator release the
switch or grasp it too tightly, servo power is immediately disabled, preventing
further robot movement. For detailed information about the operation of the
ENABLE switch, refer to the XRC section in the manipulator manual that came
with your system.
3.6.5 Interlocked Cell Door
A safety interlock on the cell entrance door prevents entry into the cell during
PLAY mode. Opening the cell door with the robot in PLAY causes an Gate
Interlock Error. Brakes are applied to the robot and all servo power is removed
from the system. The system E-STOP lights come on and all positioner motion is
stopped.
In TEACH mode, power to the table is removed if the cell door is open. In order to
sweep the table in teach, the door must be closed.
