Remote Interlock
Ground Bond is equipped with a Remote Interlock feature. Remote Interlock utilizes a
set of closed contacts to enable the instrument’s output. If the Remote Interlock
contacts are 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 Remote 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 Remote 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 Disable Key (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 Remote Interlock, the instrument will not perform
tests.
