The ratio value (VAL) is the set value divided by 10 and rounded to the whole number.

Example: Setting of 45 = 45/10 = 4.5 = 4 VAL

IFIELD = VAL ( IMOTOR x 0.029 )

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.

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.

Range

0.025 to 6.3 seconds

Set

0 to 255

Resolution

0.025 seconds per set unit

Example:

Setting of 20 = 0.5 seconds

This C/A takes effect when the Mode 1 settings are called for by the interactive Dash Display.

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 M FWS = VAL x 1.625

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.

0.029 amps

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.

IFIELD = VAL ( IMOTOR X .029 )

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.

Range

100% to 0% battery volts

Set

51 to 180

Resolution

0.78 % per set unit

Example

Setting of 71 = 84.4 % battery

 

volts

This MAX ARMATURE % ON takes effect when the Mode 1 settings are called for by the interactive Dash Display.
