Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 21
Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used on the continuous loss-in-weight blenders are primarily concerned with electrical power
disconnection and the disabling of moving parts that may need to be accessed during the
normal operation of the machine.
Some of the safety devices utilize a manual activator. This is the method of initiating the
safety lock out. This may be in the form of a plug, disconnect plug, lever or a handle. Within
this lockable handle, there may be a location for a padlock. A padlock should be placed in
the lockout handle by personnel servicing the equipment.
WARNING! At no time should anyone other than the person who installed the lockout or
unplugged a twist plug, remove the lockout, or reconnect the twist plug.
Pluggable Line Cord
This line power cord allows the operator or maintenance personnel to unplug the blending
system from its power source and tag it out. This plug may be tagged with any number of
approved electrical lockout tags. These tags are available at most electrical supply stores.
Amphenol quick connect Plug Connected to Each Auger Motor
The plug must be unlatched and the female end of the cord removed from the motor plug.
This disables the motor from turning while the auger unit is being serviced or cleaned. The
motor cords are cut to length so they must be disconnected before the auger can be removed
from the housing.
Note: Disconnect both of the items listed above before cleaning or servicing
equipment.
