Remote Interlock
HypotULTRA III is equipped with a featured referred to as “Remote Interlock”. Remote
Interlock is a feature that utilizes a set of closed contacts to enable the instruments output. In
other words, if the Interlock contacts open, the output of the instrument will be disabled.
Remote Interlock could also be referred to as a remote system lockout, utilizing “Fail When
Open” logic. If the Interlock contacts are open and the Test button is pushed, a pop-up
message will be displayed on the screen for two seconds. The message will appear as follows:
If the Interlock contacts are opened during a test, the pop-up message will be displayed and the
test will abort. The hardware and has been configured to provide the interlock connections on
pins 4 and 5 of the Remote Interface, Signal Input port. The instrument can still be used
without the external interlock device as long as the Interlock Connector (38075 provided with
unit) is plugged into the Remote Interface, Signal Input port. If there is nothing connected to
the Remote Interface, Signal Input port to provide a connection to the interlock, the instrument
will not perform tests.
