EQUIPMENT DESCRIPTION
3.6.2
Arc Screens
WARNING!
Although the arc curtain blocks dangerous arc radiation, never look
directly at the arc without protective eye wear!
Two arc screens are used on the ArcWorld IV-6200 XHD DR2C cell. The first are
the metal arc shields on the positioner. These shields block arc radiation and sparks
from the welding operation.
The material used to cover the safety fencing of the entire robotic cell acts as the
second arc screen. This arc curtain reduces the amount of ultra-violet radiation that
escapes from the robotic cell.
3.6.3
Fencing
The safety fencing provided with the ArcWorld IV-6200 XHD DR2C cell encloses
the entire robotic cell. It forms a physical barrier preventing entry into the robot
operating envelope during automatic operation. Quick-access panels protect the
headstock and tailstock housings. These panels can easily be removed for
maintenance needs.
3.6.4
Safety Light Curtains
The safety light curtains help prevent serious injury to anyone entering the
positioner area during the sweeping process. In PLAY or TEACH mode, if the
positioner is sweeping and the safety light curtain is activated, servo power is
removed from the system and all positioner motion stops. Servo power can be
reapplied by clearing the obstruction and pressing SERVO ON. Then press the
START button to continue positioner motion.
If the positioner is not in motion but the CYCLE START input has been latched
(indicated by the CYCLE LATCHED light), the CYCLE START input is
unlatched and the CYCLE LATCHED light turns off when the safety light curtain
is activated. Servo power remains ON.
3.6.5
ENABLE Switch
The ENABLE switch, located on the teach pendant, is a safety feature which
controls servo power while in TEACH mode. When pressed, 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 controller section in the manipulator
manual that came with your system.
