7.2  EMERGENCY STOP
If for any reason, the machine needs to be stopped without delay, an emergency stop mushroom 
switch is provided.  Pressing the switch stops the LS machine immediately.  It can be released by 
turning a quarter-a-turn clockwise.  The machine will then go to the initialized/start-up sequence if the 
ON/OFF switch is already ON.

7.3  SPLINTER SHIELDS
Transparent splinter shields are available as an option to enclose the test sample if there is any 
danger of samples shattering as a result of the test.  These shields can be tted with an electronic 
interlock so that the test cannot be started until the hinged shield is closed.  While not mandatory for 
many applications and countries, LLOYD INSTRUMENTS strongly recommend that users consider 
tting this optional item.
If a shield tted with electronic interlock is used, the following screen will appear if the door is opened 
during a test.
