7. PRELIMINARY SERVICE PROCEDURE Before beginning repair be sure that all installation and configuration procedures have been followed The unit routinely performs internal diagnostics following power up or reset During this period all LED s will turn ON momentarily and the green Run LED flashes If the diagnostics complete successfully the Run LED will stop flashing after two seconds and then remain ON This indicates that the unit is operating normally If the Run LED continues to flash then this is indicative of a problem In this case use the Acromag IntelliPack Configuration Software to reconfigure the module and this will usually cure the problem If the diagnostics indicate a problem via a continuously flashing green LED or if other evidence points to a problem with the unit an effective and convenient fault diagnosis method is to exchange the questionable module with a known good unit IntelliPack Series 832A Alarm User s Manual Dual RTD Input The IntelliPack Serial Port Adapter also contains a red LED visible at the small opening in the enclosure to the right of the RJ11 receptacle If this LED is OFF or Flashing then a communication interface problem exists Note that the adapter receives its power from the IntelliPack module A constant ON LED indicates a properly working and powered serial interface adapter Acromag s Application Engineers can provide further technical assistance if required Whe
