white
DISABLED indicator on the frame control panel illuminates.

General Maintenance Procedures
General maintenance procedures are the procedures that you can perform should it
become necessary. These procedures do not require an Instron
®
service technician,
although assistance is available. Contact Instron
®
Service for assistance.
Test Limit Stops
It is recommended that you periodically test both the first and second level limit stops
on the load frame.
1. Ensure that the system is on and the crosshead is stationary.
2. Secure one of the limit stops (either the upper or lower limit stop) to the limit switch
rod.
3. Firmly hold the yellow part of the limit stop to gently move the stop either downward
(in compression) or upward (in tension) about 3 mm (1/8 in).
A first level limit warning displays on the computer.
4. Repeat Step 3 moving the limit stop another 3 mm (1/8 in) in the same direction.
A second level limit warning and frame disabled warning displays on the computer.
The white LED above the
DISABLED indicator on the frame control panel illumi-
nates.
The frame disabled warning indicates that the limit stops are working correctly. If
the frame disabled warning does not display, contact your local Instron
®
Service
office for assistance.
5. Re-enable the frame (refer to “Re-enable the load frame” on page 107).
The frame is now ready to resume testing.
