SEQUENCE OF OPERATION
When the EAP 110 is energized and is interconnected to an operating system, it
will display any faults which are currently active on the MEC 2 or MEC 20 Engine
controller. Any new faults will be displayed by a flashing LED light and the
internal alarm horn will sound. Once the alarm has been acknowledged via
“ALARM SILENCE” push-button, the horn will be silenced and the LED light will
remain on continuously. Any subsequent alarms will cause the horn to sound
again and new fault LED to flash. The activated LED lights will remain on until
the fault condition has been reset at the engine controller. If the EAP 110 is also
connected to the 4 possible external contact input circuits, these faults will be
activated in the same sequence by the remote contacts closing or opening upon
a fault. Remote contacts close to initiate an alarm fault.
