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.
The following functions have function numbers larger
than the numbers on the Handset keyboard. To access
these functions. Push the CONT key and the number
shown in the following instructions at the same time.
THE SEAT SWITCH MUST BE CLOSED.
FUNCTION 48 MODE 1 (TURTLE) - ARMATURE
CONTROLLED ACCELERATION
( Push CONT 1)
This function allows for the adjustment of the rate of time it
takes for the control to accelerate to 100% applied battery
voltage to the motor on hard acceleration.

0 to 255
0.025 seconds per set unit
Setting of 20 = 0.5 seconds
FUNCTION 49 MODE 1 FIELD WEAKENING START
( Push CONT 2)
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
Example: Setting of 20 = 32.5 amps
I FWS = VAL x 1.625
M
This FIELD WEAKENING START takes effect when the
Mode 1 settings are called for by the interactive Dash
Display.
FUNCTION 50 MODE 1 FW RATIO
( Push CONT 3 )
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
changed.
Volts
48
72/80
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.
I = VAL ( I X .024 )
FIELD MOTOR
This FW RATIO takes effect when the Mode 1 settings are
called for by the interactive Dash Display.
FUNCTION 51 MODE 1 MAX ARMATURE % ON
( Push CONT 4)
This function allows for the adjustment of the speed limit
(maximum battery volts to the motor) when the SL1 limit
switch input signal is received by the control card. The SL1
limit switch is a normally closed switch connected to
battery negative; the switch opening enables speed limit.
