Extrusion Control & Extruder Monitor Units Chapter 2: Functional Description
15
Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are 
used on these extrusion control & extruder monitor units are primarily concerned with 
pneumatic and 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, lever or a handle. Within this lockable 
handle, there may be a location for a padlock. Personnel servicing the equipment should 
place a padlock in the lockout handle. 
In addition to the safety devices listed above, these extrusion control & extrusion monitor 
units are equipped with a line cord plug. This allows the operator or maintenance personnel 
to unplug the unit from its power source and tag it out. The plug can then be tagged with any 
number of approved electrical lockout tags available at most electrical supply stores. 
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning the extrusion control or extruder monitor units. 
Failure to do so may result in serious injury. No one but the person who installed the 
lockout may remove it.
