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 5.3.2 of this instruction booklet.
FUNCTION 48 MODE 1 - 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. The 1A contactor
will automatically close 0.2 seconds after the controlled
acceleration stops and the accelerator input is less than 0.5
volts or less than 200 ohms.
Range 0.1 to 22.0 seconds
Set 0 to 255
Resolution 0.084 seconds per set unit
Example Setting of 20 = 1.78 seconds C/A
and 1.98 seconds 1A time
This C/A TIME takes effect when the Mode 1 settings are
called for by Function 1.
FUNCTION 49 MODE 1 FIELD WEAKENING START
(Push CONT 2)
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
This FIELD WEAKENING START takes effect when the
Mode 1 settings are called for by Function 1.
FUNCTION 50 MODE 1 MINIMUM FIELD CURRENT
(Push CONT 3)
This function allows the adjustment of the field weakening
level in order to set the top speed of the motor.

This MINIMUM FIELD CURRENT takes effect when the
Mode 1 settings are called for by Function 1.
FUNCTION 51 MODE 1 RATIO
(Push CONT 4)
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.

This RATIO takes effect when the Mode 1 settings are
called for by Function 1.
FUNCTION 52 MODE 1 REGEN ARMATURE CURRENT
LIMIT
(Push CONT 5)
This function allows for the adjustment of the regen braking
current limit of the control. The correlation between the
function setting and the regen braking current is expressed
by the following equation:
I
R
= [[function setting/4] x 6.5]
Note: 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.
USER SELECTABLE MODES
The following functions (Functions 48 through 62) are
mode settings that are activated by Function 1. Each
function must be set using the logic table shown below.
Mode Handset Setting
1 0 to 63
2 64 to 127
3 128 to 255
