ADJUSTABLE FEATURES
SX TRANSISTOR CONTROLS Page 59
Revised May 2003
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 99
99 Hours
FUNCTION 21 AUTO REGEN BRAKING C/L
(Push CONT 6)
This function allows for the adjustment of the regen braking
current limit when the accelerator is released.

FUNCTION 23 PLUG/REGEN TRANSITION POINT
( Push CONT 8)
This function allows for the adjustment of the vehicle speed
at which the vehicle transitions from regen braking to plug
braking.
VAL x 0.1 = MPH
Example: Setting of 30 = 30 x 0.1 = 3.0 MPH
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

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 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 Change Set Resolution
36/48 .48 0 to 40 .024
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.
Note: When scrolling through the stored status code
register, the register always starts at status code 1 and
scrolls to status code 16. Instructions for scrolling the
register are in section 6.3.2 of this instruction booklet.
DASH DISPLAY INTERACTIVE MODES
The following functions (functions 48 through 62) are
mode settings that are activated from the Interactive Dash
Display. Each function must be set using the logic table
shown below. If you try to set this function outside these
guidelines, an error code will be displayed to prompt you
to enter the correct setting:
If “80” is displayed, the setting is too low.
If “81” is displayed, the setting is too high.
