(1) This feature is not set at the factory.Note: A control box that is a replacement will have these settings. Note the settings of the DIP switches prior to removing a controller or replacing a controller. Set the switches on the replacement to the same designation.Setup of the ECM Controlled System
The following procedures are only valid for systems that are controlled by the ECM on Track-Type Tractors. The setup of the ECM controlled system is performed with Electronic Technician (ET).

Parameter Settings for the Flexxaire Fan on the ECM
Parameter Description Default Range
Variable Pitch Fan Enable or Disable the entire Flexxaire Fan Disable Disable or Enable
Manual Purge Enable or Disable the manual purge switch Enable Disable or Enable

D6R III N/A N/A
D6T N/A N/A
D7R N/A N/A
D8R OFF ON or OFF
D9R ON ON or OFF
D10R OFF ON or OFF
Purge Cycle Interval Set the time interval between purges 20 minutes 5 - 120 minutes
Purge Cycle Duration Set the duration for an individual purge 15 seconds 5 - 30 seconds
Fan Blade Cooling Position Set the normal direction of the air flow PUSH PUSH or PULL The parameter for the variable pitch fan controls the operation of the entire Flexxaire Fan. Select “Enable” or “Disable ”. When “Disable” is selected, the blades will not go into pitch. The blades will remain in NEUTRAL.The parameter for the manual purge switch controls the operation of the manual purge switch that is located on the dash. Select “Enable” or “Disable ”. When “Disable” is selected, the button will not start a purge cycle.The parameter to suspend purges, controls the automatic purge function. If the parameter is enabled, purges will not occur when the machine is in a forward gear. Purge suspend is useful when the tractor is working with wooden chips or the machine is used in landfill applications. If the fan goes through a purge cycle in a forward gear, debris that falls over the top of the blade may be drawn into the front of the radiator. Purge suspend delays the automatic purge until the tractor is in REVERSE in order to avoid plugging the radiator. “Enable” allows purges only when the machine is in REVERSE. “Disable” allows purges in FORWARD or REVERSE.The parameter for the fan speed solenoid controls the operation of the standard demand fan. Select “OFF” for operation of the Flexxaire Fan.The parameter for the purge cycle interval controls the time between purges. A shorter time between purges causes more wear on the components. Set the time at the maximum amount of time that will keep the radiator clean.The parameter for the purge cycle duration controls the length of the purge. Set the time to allow the radiator and the engine enclosures to be cleaned of
