…Interlock Fault
If an interlock fault is suspected, execute the following steps.
[ ] Cycle DC power OFF/ON.
[ ] Verify the supply voltage is between 4.8 and 6.5 VDC.
[ ] Connect a computer and send the "?LCK" or "?INT" query.
If a value of 0 is returned, check all interlock…

The system will not operate with the interlock open. An interlock
connector is located on the power supply rear panel. The interlock
status is monitored by the CPU. If the interlock is open, the message,
"External Interlock Fault" will be displayed on…
