FUNCTION 13	SPEED LIMIT 3
	( Push 13 )

The SL3 set speed limit is activated by the Truck Management Module 90, 91 and 92. See Section 5 for Truck Management Module details.

FUNCTION 14 INTERNAL RESISTANCE COMPENSATION

( Push 14 )

This function is used when the Battery Discharge Indicator is present. Adjustment of this function will improve the accuracy of the BDI. In order to determine this setting the voltage drop of the battery under load must first be calculated by the following method:

1.Load the traction motor to 100 amps at 100% on-time of the control and record the open circuit voltage (VO) at the control panel positive and negative power terminal.

2.Load the traction motor to 200 amps at 100% on time of the control and record the voltage (VL) at the control panel positive and negative power terminal.

3.Calculate voltage drop (VDrop) as follows:

VDrop = VO - VL

4.Use the table below to determine the appropriate setting using the calculated VDrop as a reference.

FUNCTION 15		BATTERY VOLTS
		(Push l5)

This function allows for the adjustment of voltage range for controls equipped with the Battery Discharge Indication function. In order for the BDI to operate properly, the setting as shown in the table must be entered:

Battery volts	Set units
24 volts	Between 0 and 31
36 volts	Between 32 and 44
48 volts	Between 45 and 69
72 volts	Between 70 and 80
80 volts	Between 81 and 183
36/48 volts	Between 184 and 250
No BDI	Between 251 and 255

The following functions have function numbers larger than the numbers on the Handset keyboard. To access these functions, push the CONT key and the number shown in the following instructions at the same time.

.FUNCTION 16 STALL TRIP POINT WITH % ON-TIME ( Push CONT 1)

This function allows for the adjustment of control percent on time for the stall motor trip point

Control % On time = 163 -(Set Point Val)*.892

If 163 or greater, then “0.0” % on time

If 51 or less, then “100.”% on-time

FUNCTION 17 CARD TYPE SELECTION ( Push CONT 2 )

This function allows for the selection of the card type used for your vehicle's application. The table below shows the setting to select card application type, depending on which control card is used. Note that the right (slave) control for a dual motor proportioning system will be set differently than the left (master) control.

Note: Non-Auto Plug/Regen Logic cards must be used for settings below:

FUNCTIONS	STANDARD	REGEN
Std C/L	5 to 9	45 to 49
Std C/L (Right)	69 to 73	109 to 113

Note: Auto Plug/Regen Logic cards must be used for settings below:

FUNCTIONS	STANDARD	REGEN
Std C/L Auto Plug	15 to 19	55 to 59
Std C/L Auto Plug (Right)	79 to 83	119 to 123

Settings for these functions should be made within the ranges indicated above.

Warning: These settings must be changed by authorized personnel only, following instructions supplied by the
