Operational Safety; Lockout Device - Dukane VWA-4300 User Manual

Never attempt to remove
the filter housing while the
compressed air is on. Turn
off the compressed air us-
ing the pneumatic lockout
device, and make sure the
pressure gauge reads zero.

Operational Safety

The service doors are interlocked to prevent access while
the welder is energized. If either of the hydraulic doors are
opened, the vibration welder will shut down. The electri-
cal cabinet service door is shown in Figure 2-7. It cannot
be opened without first turning off the CE-compliant AC
disconnect. The rear hydraulic service doors are identified
in Figure 2-8.
The front loading area is protected by a sliding access
door. This door is operated by two air cylinders which
are driven by compressed air. The door raises at the
start of a welding cycle to prevent access to the tooling
and lift table. The door also serves as part of the sound
enclosure. Sensors on the access door will stop the welder
if the compressed air fails and allows the door to open
partially during a weld cycle.
The safety light curtains prevent any access to the loading
area once the machine cycle has started and before the
access door is fully closed. Breaking the light beam while
the door is in transition will cause the machine to halt
operation. The light curtains are identified in Figure 2-7.
Figures represent typical hardware and
placement but may not show individual cus-
tom options.
