Section 6.6 Setup Functions for Hydraulic Pump Control 

 

This function is not applicable to this type of control and 

should not be adjusted. 

 
FUNCTION 2:   

 

This function allows for the adjustment of the current level 

at which the internal resistance compensation feature 

(Function 16) will take effect. 

 

Range   

0 to 1325 amps   

Setting   

52 to 255 

Resolution 

6.5 amps per set unit 

 

Example: Setting of 72 =  (72-52) x 6.5 = 130 amps  

 
FUNCTION 3:  

 

This function allows for the adjustment of the rate of time it 

takes for the control to accelerate to 96% applied battery 

voltage to the motor on hard acceleration.   

 

Range    

0.1 to 5.5 seconds 

Setting   

0 to 255 

Resolution 

0.021 seconds per set unit 

 

Example: Setting of 20 = 0.52 seconds C/A 

 
FUNCTION 4:  

 

This function allows for the adjustment of the current limit 

of the control. The rating of the control will determine the 

range of adjustment for this function. Please refer to the 

OEM operating instructions for the control used in your 

vehicle. 

 

Range   

See OEM control C/L curves 

Setting   

0 to 255 

 

Example: 0 = min. current, 255 = max. current 

 
This function allows for the adjustment of the rate of time it 

takes for the control to add the internal resistance 

compensation voltage that is applied to the motor. This 

function will add 0.375 volts to the motor at the rate of time 

adjusted until the total IR compensation voltage has been 

added.  

 

Range    

0.0015 to 0.383 seconds 

Setting   

0 to 255 

Resolution 

0.0015 seconds per set unit 

 

Example: Setting of 20 = 0.032 seconds  

For example, if you had selected 2.08 volts from Function 16 

to be added to the motor, it would take 0.18 seconds to add 

a total of 2.08 volts.  (2.08/0.375)=0.032 

 

 
This function allows for the adjustment of the speed limit 

(maximum battery volts to the motor) when the SL1 limit 

switch input signal is received by the control card.   SL1 

limit switch is a normally open switch connected to battery 

negative, the switch closing enables speed limit. 

 

Range   

0% to 100% battery volts 

Setting   

0 to 255 

Resolution 

0.375 volts per set unit 

 

Example: Setting of 50=18.75 volts  

 

 

 

 

Same as Function 11 except using SL2 limit switch for input. 

 
FUNCTION 13: 

 
Same as Function 11 except using SL3 limit switch for input. 

 
FUNCTION 14: 

This function is not applicable to this type of control and 

should not be adjusted. 

SPEED / TORQUE  COMPENSATION 

(Push CONT  1) 

This function is used to stabilize pump speed at heavy 

loads.   The voltage selected will be added to the motor at 

each 100 amp increment starting at the value set in 

Function 2.  The voltage compensation selected will be 

added in increments of 0.375 volts until the entire voltage is 

added.  For example,  a setting of 2 will be added in 30 steps
