High Idle to activate before any electric loads are shed and deactivate with the <br />service brake. <br />If enabled: <br />"Load Man Hi -Idle On" shall display on the information <br />center. <br />Hi -Idle shall not activate until 30 seconds after engine start <br />up. <br />Individual switch "on" indicatorto flash when the particular load has been shed. <br />The information center indicates system voltage. <br />The information center, where applicable, includes a "Load Manager' screen indicating the <br />following: <br />Load managed items list, with priority levels and item condition. <br />Individual load managed item condition: <br />ON = not shed <br />SHED = shed <br />SEQUENCER <br />A sequencer shall be provided that automatically activates and deactivates vehicle loads in a <br />preset sequence thereby protecting the alternator from power surges. This sequencer <br />operation shall allow a gradual increase or decrease in alternator output, rather than loading <br />or dumping the entire 12-volt load to prolong the life of the alternator. <br />For improved reliability and ease of use, the load sequencing system shall be an integral part <br />of the vehicle's solid-state control system requiring no additional components to perform <br />load sequencing tasks. Load sequencing systems which require additional components shall <br />not be allowed. <br />Emergency light sequencing shall operate in conjunction with the emergency master light <br />switch. When the emergency master switch is activated, the emergency lights shall be <br />activated one by one at half -second intervals. Sequenced emergency light switch indicators <br />shall flash while waiting for activation. <br />When the emergency master switch is deactivated, the sequencer shall deactivate the warning <br />light loads in the reverse order. <br />Sequencing of the following items shall also occur, in conjunction with the ignition switch, at <br />half -second intervals: <br />Cab Heater and Air Conditioning <br />Crew Cab Heater (if applicable) <br />Crew Cab Air Conditioning (if applicable) <br />Exhaust Fans (if applicable) <br />Third Evaporator(if applicable) <br />44 <br />
