1.2 Operating Status LEDs and Diagnostic Display
The Module has three Operating Status LEDs (one each red,
yellow and green), plus a 2-digit Diagnostic Display, visible
through a window in the front cover. The individual LEDs provide
constant, ongoing system status information at a glance. The
Diagnostic Display provides error codes that correspond to the
cause of a fault or configuration error which results in a lockout,
and other more detailed conditions. See Sections 4 and 5 for
further information.
