7.4 Responsible Use of Interlock Override
Overriding the guard interlock enables the door to be opened without interrupting the test
stand’s ability to move. Although the interlock should, typically, always be functioning (not
overridden) there are some scenarios where the interlock may need to be disabled, examples
include:

Test Setup –
When first setting up the test stand with grips and sample, it is often
necessary to make several manual adjustments to the fixtures. In this scenario
overriding the interlock enables better access and visibility of the fixtures, thus
helping to reduce setup time when compared to the same procedure with the guard’s
interlock active. The interlock should be reactivated upon completing the setup.

Test Stand Servicing –
Certain service procedures will require the interlock to be
overridden. Servicing is only to be undertaken by Mecmesin or an approved
distributor.
A full risk assessment should be carried out for the process of operating the
test stand with the interlocked guard overridden. Clear procedures should be
defined to determine when it is safe to operate under these conditions.
