vehicle manufacturer. Card type selection must be made within the capabilities of the control panel used and the supporting electro mechanical devices. Failure to comply with proper application standards could result in mis- operation or damage to the control and/or motors.

FUNCTION 18 STEER PUMP TIME DELAY ( Push CONT 3 )

This function allows for the selection of steer pump contactor pick up input, either seat switch or directional switch closing, and adjustment of the time delay for the contactor drop out.

•Pick up steer pump contactor on seat switch closure and time delay drop out of steer pump contactor on seat switch opening:

Range

1.5 to 65 seconds

Setting

Between 0 and 128

Resolution

0.5 seconds per set unit

Example: Setting of 20 = (20 x 0.5) + 1.5 = 11.5 seconds

•Pick up steer pump contactor on directional switch closure and time delay drop out of steer pump contactor on directional switch opening:

Range

0.5 to 63 seconds

Setting

Between 129 and 255

Resolution

0.5 seconds per set unit

Example: Setting of 149 = ((149-129) x 0.5) + 1.5 = 11.5 seconds

Note: Contactor drop out will be 1.5 seconds after the seat switch opens.

FUNCTION 19 MAINTENANCE CODE TENS AND UNITS HOURS SET

( Push CONT 4 )

This function allows for the adjustment of the tens and units hours of the maintenance code activation time.

Range

0 to 99

Set

0 to 99

Example

9999 Hours

FUNCTION 20 MAINTENANCE CODE THOUSANDS AND HUNDREDS HOURS SET

( Push CONT 5 )

This function allows for the adjustment of the thousands and hundreds hours of the maintenance code activation time.

Range

0 to 240

Set

0 to 240

Example

9999 Hours

FUNCTION 21 AUTO REGEN BRAKING C/L (Push CONT 6)

This function allows for the adjustment of the Regen braking current limit. High current value correlates to shorter stopping distance.

Setting greater than 143 disables this function.

FUNCTION 24 FIELD WEAKENING START ( Push CONT 9)

This function allows for setting the armature current at which minimum field current will achieved .

Range

0 to 414 Amps

Setting

0 to 255

Resolution

1.625 per set unit

I MOTOR FWS = VAL. x 1.625

Example: Setting of 20 = 32.5 amps

FUNCTION 25 MONITOR

( Push CONT 10)

This function allows the monitoring of certain control functions by looking directly at the RAM of the microprocessor. Because absolute memory locations need to be known, this function should not be used without detailed instructions from the GE application engineer.

This function should only be adjusted by the vehicle OEM. To ensure optimum operation of the control, this function must be left with zero stored in this register.

FUNCTION 26 BASE RATIO

( Push CONT 11)

This function sets the ratio between armature and field current when operating below the maximum field current and above the Field Weakening Start point. The setting represents the quantity of field current changed for each 1 amp of armature current changed.
