General Information
The annunciator module is used to indicate various
system events and conditions. The annunciator
module uses indicator lights and an audible horn to
give the operator information about the current status
of the system. The annunciator module can be used
to announce faults and/or status signals to the
operator. The annunciator module allows the
operator to silence the horn. The annunciator module
also allows the operator to acknowledge faults to the
system.
There are seventeen pair of LED indicators on the
annunciator's front panel. Sixteen pair of LED
indicators are used to announce events, diagnostics,
and ready signals. The seventeenth pair of LED
indicators is used as a combined network/module
status LED. The seventeenth pair of LED indicators
can tell the operator if there is a problem with the
J1939 data link connection.
