Safety Enclosure for Automated Dispensing Systems
Operation
Once the robot is properly installed in the enclosure, follow these procedures for
routine operation to ensure personnel safety.
Starting the System
1. Turn the main disconnect switch located on the back of the safety enclosure
to the ON position.
2. Refer to the robot operating manual for additional robot-specific power-on
steps (such as switching on the DispenseMotion controller).
NOTE:
When the system is powered on, the light curtain and all I/O
connections are automatically active. If the light curtain is interrupted by
any passing object (such as a hand reaching into the enclosure), the system
enters an emergency stop condition. An emergency stop may also be
triggered by a customer-specific I/O connection.
3. Press the EMERGENCY STOP button to test it. If an emergency shutdown
occurs, the system is operating properly.
4. Verify that the light curtain is functioning properly by moving a
test object into the light curtain field. If an emergency shutdown
occurs, the system is operating properly.
NOTE:
Nordson EFD strongly recommends performing the
following additional checks of the light curtain operation:
• Ensure that the safety enclosure is in a location that is free of
light interference, such as from fluorescent lamps.
• Check the sheaths of the wiring connected to the light curtain
controller (inside the electrical box) for damage and replace
any damaged wiring. Refer to “Service” on page 21 for the
location of the light curtain controller.
About the RUN/TEACH Switch
The safety enclosure provides a RUN/TEACH switch that affects
system operation. The default position of the RUN/TEACH switch is
the RUN position, which allows normal operation. Placing the switch
in the TEACH position deactivates the light curtain, allowing the
operator to run the robot at a reduced speed (without dispensing) or
to service the robot. When the RUN/TEACH switch is in the TEACH
position, the system will not run a dispense cycle.
When the RUN/TEACH switch is in the RUN position:
• The light curtain is active — any object that passes the light curtain causes an
emergency shutdown condition.
• Pressing the green START button starts a dispense cycle.
When the RUN/TEACH switch is in the TEACH position:
• The light curtain is deactivated, allowing the operator to reach inside the
enclosure without triggering an emergency shutdown.
• The robot cannot execute a dispense program.
