Disconnect Switch
There is one disconnect switch located on the main electrical enclosure.
Figure 4-4: Everything You Need to Know About Disconnect Switches
Interlocked Doors or Guards
Overview
Four doors located on the saw chamber are interlocked with the safety system to
prevent entry while components are moving. Each door includes an open
pushbutton that, when pressed for 1 second, will unlock the door if specific
requirements are met. Each door may also be opened manually with the use of an
bypass key.
See Figure 4-5 for the location of each door and pushbutton.
Unlocking
When all of the following requirements are met, an open pushbutton may be used
to unlock one of the saw chamber doors. If the following requirements are not met,
the open pushbuttons will not work:
• Completed cycle and an E-stop is actuated
• Pneumatic power is shut off
!
WARNING
Always turn off power at the main power source before opening the
electrical enclosure.
Even when the disconnect switch is turned to the Off position, there is
still live power to the enclosure where the disconnect switch is
mounted. This live power may cause severe electric shock.
Turning the disconnect handle to the
On position supplies electrical power
to the entire machine. To remove
power to the machine, turn the
disconnect handle to the Off position.
The disconnect handle should be
turned off when the machine is not in
use.
If an
electrical
lockout/
tagout is in
place, the
push-
buttons will
not function.
