7.2 MultiTest- dV and OmniTest Interlocked Guard Examples
Example 1
In this example, the authorised user requires the door to be open while jogging the test
stand. A scenario where jogging the machine with the door open may be beneficial is when
first fitting a set of grips to the test stand.
As the interlock key switch is set to ‘0’ (override plug connected for MultiTest- dV test
stands), the guarding does not restrict the test stand’s movement and the system can be
jogged with the door open. If the interlock key switch is set back to ‘1’ (interlock guard
connected for MultiTest-
dV
test stands) the operator will be unable to jog the machine with
the door open.
Example 2
In this example, the operator is attempting to jog the test stand with the door open, but the
stand will not move.
As the interlock system is active, the test stand is displaying the error message ‘INTERLOCK
ACTIVE’. The test stand’s motor will remain restricted until the door is closed. Once the
door is closed the error condition will disappear, allowing the test stand to be moved.
Example 3
In this example, the operator has opened the guard door while the test was running. As the
interlock system is active, the test will immediately stop, and the test stand will display the
following message ‘INTERLOCK ACTIVE’. If the test stand is being used injunction with
VectorPro, the data capture for the sample will be aborted and a warning message will be
displayed. The motor drive will remain inhibited until the door is closed.
