Section 6.6 Setup Functions for Hydraulic Pump Control

FUNCTION 1:

NOT APPLICABLE

This function is not applicable to this type of control and should not be adjusted.

FUNCTION 2: INTERNAL RESISTANCE COMPENSATION START (Push 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: CONTROLLED ACCELERATION (Push 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:

CURRENT LIMIT

 

(Push 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

FUNCTION 7: INTERNAL RESISTANCE COMPENSATION RATE (Push 7)

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

FUNCTION 11: SPEED LIMIT 1 (SL1) (Push 11)

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

FUNCTION 12: SPEED LIMIT 2 (SL2) (Push 12)

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

FUNCTION 13: SPEED LIMIT 3 (SL3) (Push 13)

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

FUNCTION 14: NOT APPLICABLE

This function is not applicable to this type of control and should not be adjusted.

Note: 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. THE KEY SWITCH MUST BE OPEN.

FUNCTION 16: 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
