Resolution
0.5 seconds per set unit
Example: Setting of 20 = (20 x 0.5) + 1.5 = 11.5 seconds
Or:
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: Line 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. The higher the current the shorter the
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 be achieved .
Range
0 to 414 Amps
Setting
0 to 255
Resolution

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.
Volts
Max Field Ref
48 60
72/80 55
The ratio value (VAL) is the set value divided by 10 and
rounded to the lowest whole number.
Example : Setting of 45 = 45/10 = 4.5 = 4 VAL.

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
code pointer number"
[the number shown in
(bold italics)
in the HS (Handset) number column] on the memory map,
with the number obtained from Function 28. This will be the
last stored status code recorded.
