42 Remote Control TOS8030
6.2 Using the INTERLOCK Terminal
• Short-circuiting the INTERLOCK terminals with the provided jumper is a
convenient way to cancel the PROTECTION function, but this jumper
should only be used when the tester is being temporarily operated for
inspection. For safety, always enable the interlock function when perform-
ing actual testing.
To ensure user safety, the TOS8030 interlock function interlocks with external
equipment to shut down output. When this function is activated, a PROTECTION
state is invoked and output is shut off, preventing further testing. When this function
is activated, the PROTECTION state cannot be cancelled simply by pressing the
STOP switch on the front panel or by issuing a STOP signal from the remote con-
trol.
For improved safety, the interlock function allows testing to be controlled from an
external device.
When using the tester, take advantage of the interlock function to improve opera-
tional safety. Consider the following examples:
•
A cover covering the DUT is provided as an electric shock-prevention device;
the status of the interlock function is linked to the opening and closing of the
cover.
• Fences are installed around locations where testing is performed; the status of
the interlock function is linked to the opening and closing of the fence.
Using the interlock function
Opening the INTERLOCK terminals on the rear panel activates the interlock func-
tion. This invokes the PROTECTION state.
To cancel the PROTECTION state invoked by the interlock function, short-circuit
the terminals. Press the front panel STOP switch or send a STOP signal from the
remote control.
