Stop a test
Product Support: www.instron.com
The Emergency Stop button on the testing system is a large, round, red button with a
yellow background. Press this button to stop the test as soon as possible when a
condition develops that:
• Could affect the safety of persons operating the system.
• Could damage the specimen, load frame, or test fixtures.
Investigate and resolve the situation that caused the use of the Emergency Stop button
before you reset the system.
When operated, the Emergency Stop button locks into the closed position and the
system is disabled until you reset the button and re-enable the load frame.
If you are using an integrated air kit with a foot switch to control a set of pneumatic
grips, be aware that pressing the Emergency Stop button to disable the frame will
also deactivate the grips, causing them to open.
With an integrated air kit, any action that disables the frame will also open the grips.
Re-enable the load frame
To reset the Emergency Stop button, rotate the button a quarter-turn clockwise until it
resets.
The steps to re-enable the frame are different between a system with and without an
interlock.
• In a system without interlocks:
a. Press the
UNLOCK button on the frame control panel.
The frame proceeds to
SET UP mode.
• In a system with interlocks:
a. Open the interlock.
b. Close the interlock.
• In addition, in a system with interlocks where the interlock behavior is configured
under Operator Protection to Allow limited motion:
a. Press the
UNLOCK button on the frame control panel.
