Navigating the HMI screens
Startup screens
The screen shown below is the ZSI test box startup screen. This
screen should show up each time the test box is powered on. If
this screen does not show up when the device is powered on,
contact Eaton customer support. The test program may need to be
re-loaded.
These instructions reinforce the need to confirm that the breakers
being tested have had the correct settings configured as well as the
correct cable connections made to the ZSI best box. Please review
the previous sections of this manual if there are any concerns over
proper connections. Once the check box has been selected, the
“Test Screen” button becomes visible.
Digitrip settings screen
The “Digitrip Settings” button will take you to the Digitrip settings
screen shown below. Here, you can select which Digitrip model you
are testing and find all of the settings required to be enabled on the
trip units in order to successfully test them using the ZSI test box.
Zone configuration screen
The “Zone Config” button will take you to the zone configuration
screen which will give you single line representations of the configu-
rations tested based on your selections made regarding lineup
arrangement and fault location. (Example shows double ended
arrangement with a main fault.)
Test sequence screen
The “Test Sequence” button will take you to the test sequence
screen describing the required test sequence in order to validate
correct ZSI operation based on the arrangement you have selected
(Single vs double ended arrangements)
