The following equationshould be used to determine the appropriate setting for thisfunction:Set = 10 x 3600 x 2 x Pi x RR5280 x 12 x PPR x 0.010FUNCTION 2 CREEP SPEED( Push 2 )This function allows for the adjustment of the creep speedof the vehicle. Creep speed can be adjusted when anaccelerator input voltage between 3.9 and 3.3 volts or anaccelerator ohm input between 6K and 4.0K ohms isprovided.Range 2% to 15% on timeSet 0 to 255Resolution 0.05% per set unitExample: Setting of 20 = 3% on timeImportant Note: This function is used to optimize motorand control performance and this setting will bedetermined by GE and OEM engineers at the time ofvehicle development. This setting must not be changed byfield personnel without the permission of the OEM.FUNCTION 3 ARMATURE CONTROLLEDACCELERATION(Push 3)This function allows for the adjustment of the rate of time ittakes for the control to accelerate to 100% applied batteryvoltage to the motor on hard acceleration.Range 0.025 to 6.3 secondsSet 0 to 255Resolution 0.025 seconds per set unitExample: Setting of 20 = 0.5 secondsFUNCTION 4 SPEED REGULATION/DECREASINGFIELD(Push 4)This function allows for the adjustment of over speedregulation. It allows the user to set the rate at which thefield current is decreased when the vehicle speed is lessthan the over speed limit.Range 0.0015 to 0.383 secondsSet 0 to 255Resolution 0.0015 seconds/unitExample: (20 x 0.0015) + 0.0015 = 0.032 secFUNCTION 5 POTENTIOMETER/DIRECTIONALSWITCH CALIBRATION( Push 5 )This function allows the user to alternate between thestandard configuration of the truck (with control via theaccelerator potentiometer) or the optional configuration ofthe truck (with control via the directional switches).Set Mode Control Via16 to 32 Standard Accelerator potentiometer144 to 160 Optional Directional switchesFUNCTION 6 MPH BL3C SPEED LIMIT( Push 6 )This function is adjusts the value of the over speed limit ofthe control.Resolution 1 set unit = 0.1 MPHExample Setting of 100 = 10 MPH
