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.
•=

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 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
