TOS9200/9201 Using Terminals and Connectors 4-11
4.3 INTERLOCK Connector
As a means of ensuring the safety of the operator, the tester is equipped with an
interlock function to cut off output in coordination with external devices.
Once the interlock input terminals are opened, the interlock function activates to
shift the tester to the PROTECTION status (“PROTECTION” lights up). The output
is cut off to disable testing. In this status, it is impossible to start a test using the
START switch (*1) or cancel the PROTECTION status using the STOP switch (*2).
The interlock function restricts the tester’s output from outside to ensure the safety
of the operator.
If the interlock function shifts the tester to the PROTECTION status, short-circuit
the interlock input terminals to disable the INTERLOCK signal. Then, cancel the
status using the STOP switch.
*1: Includes the REMOTE terminal, START signal for SIGNAL I/O, and START
command for GPIB and RS-232C
*2: Includes the REMOTE terminal, STOP signal for SIGNAL I/O, and STOP com-
mand for GPIB and RS-232C
• The fi rst time the tester is turned on following delivery, the interlock func-
tion activates and testing is disabled. An interlock jumper is provided with
the product to be used for performance checks. Use this jumper only to
temporarily cancel the protection function.
When installing the tester, use the interlock function as much as possible
to ensure safety. When using jigs and devices in withstanding voltage and
insulation resistance testing, provide a safety cover that encloses the DUT
and cuts off output while the cover is open. Alternatively, to prevent electric
shock, set up a safety fence around the testing area that cuts off output in
coordination with door movements.
