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 = 11.5 seconds
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 tens and
units hours of the maintenance code activation time.
Range
0
to
99
Set
0
to
99
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. The higher the current the shorter the
stopping distance.
Setting greater than 143 disables this function.

FUNCTION 23
REGEN CANCEL
(Push CONT 8)
Function adjusts the motor current for regen cancel.
Range: 52 - 260 amps
Setting: 0 to 255
Resolution: .815 per set unit
Example: Setting of 20 = (20*.815)+52 = 68.3
FUNCTION 24
FIELD WEAKENING START
(Push CONT 9)
This function allows for setting the armature current at
which minimum field current will be achieved.
Range
0 to 414 amps
Setting
0
to
255
Resolution
1.625 per set unit
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.
To ensure optimum operation of the control, this function
must be left with zero stored in this register.
FUNCTION 26
RATIO
( Push CONT 11)
This function sets the ratio between armature and field
current when transitioning from minimum field to maximum
field current. The setting represents the quantity of field
current changed for each 1 amp of armature current above
the armature current determined by setting of Function 24.
FIELD CURRENT = (VALUE OF ) x (MOTOR CURRENT - VALUE OF) x .0074

FUNCTION 28
STORED STATUS CODE COUNT
POINTER
( Push CONT 13)
This register contains the location of the last stored status
code recorded of the 16 stored status codes. These stored
status codes have caused a PMT controller shutdown
and/or disruption of normal vehicle operation.
To determine which stored status code was the last one
recorded, read the number stored in Function 28. Using the
Memory Map for your logic card, match the "stored status
