General Information

Maintenance Screens

All of the data inputs from the engine, generator, inputs/outputs, schedule and Power Zone™ controller are visible
on the maintenance screens.
The information displayed on the maintenance screens can be used to identify, diagnose and troubleshoot unit
shutdown conditions and poor unit performance. The maintenance screens can be accessed from any Operator
screen by pressing any directional arrow (▲, ►, ▼, ◄).
The bottom of the screens have a list of available tabs, with the currently displayed tab highlighted in blue. The tabs
can be selected by using the ▲ or ▼ buttons. To the left of the tabs, the current/available pages are displayed. The
pages within a tab can be viewed by using the ▲ and ▼ buttons. Whenever a new tab is selected, the current page
will always be page 1.
Generator Summary
The Generator Summary can be found at the top of all maintenance screens and provides an overview of the system.
Engine Tab
The Engine tab contains maintenance and instrumentation data gathered from the engine itself. Above the engine
analog meters is a row of alarm icons. Each icon can be one of three colors: grey (inactive), yellow (warning) or red
(shutdown). The alarm icons are as follows from left to right: water in fuel, emission filter, engine air inlet temperature,
charge alternator, oil pressure, fuel level, battery voltage, coolant temperature, and ECU lamp.
Note: The content may change depending upon the selected engine and the features supported by the engine.
Generator Tab
The Generator tab contains maintenance and instrumentation data gathered from the generator. Each page highlights
different data gathered by the generator with the analog meters changing accordingly. The last two pages will display
the information in the bar graph. The bar graph shows blue for positive and red for negative. For the power factor
bar graph, blue is for lagging pf and red is for leading pf.
Note: The content may change, depending upon the selected generator and the features supported by the generator.
