Safety interlocks
Failure to make sure that the safety interlock and safety shields and guards are properly
installed and arranged as indicated will put personnel in severe danger. Severe personal
injury or death due to electric shock or electrocution may result.
For the safety interlock to function properly, the DUT interlock sensor must be installed near
the DUT connections and the interlock magnet must be installed on the safety shield. It must
be set up so that when the magnet is near the switch (interlock closed) the operator cannot
touch voltage-carrying conductors. If not properly installed, it will render the interlock
inoperative and place personnel at severe risk.
For operator safety, the S530 has interlocks on both the front and back cabinet doors and at the
device under test (DUT). Also, the optional probe card adapter (PCA) has an interlock that provides
protection for connections to a prober.
If you open a cabinet door or open the DUT interlock while instruments are sourcing, the interlock
activates and disconnects the hazardous voltage from the source-measure instruments, stopping any
tests in progress.
An indicator on the front door of the S530 cabinet illuminates, and the ACS or KTE software
immediately notifies you of the interlock activation.
Figure 41: Interlock indicator
Once the interlock has been activated, you must clear the cause of the interlock activation.
To clear the interlock activation:
1.
Follow the instructions on the computer.
2.
Make sure the front and rear doors are closed.
3.
Make sure the DUT interlock is properly set for safe operation.
4.
Close the DUT safety shield.
5.
The software will then need to recover before you can continue normal operation (you may need
to rerun your tests).
