BASIC OPERATION AND FEATURES

SX TRANSISTOR CONTROL

Page 8

April 1999

Note: The Status Code Instruction Sheets do not purport to

cover all possible causes of a display of a "status code ".

They do provide instructions for checking the most direct

inputs that can cause status codes to appear.

Section 2.3.2.b Stored Status Codes

This feature records the last 16 "Stored Status Codes" that

have caused a PMT controller shut down and/or disrupted

normal vehicle operation. (PMT type faults are reset by

cycling the key switch). These status codes, along with the

corresponding BDI and hourmeter readings, can be

accessed with the Handset, or by using the RS 232

communications port and dumping the information to a

Personal Computer terminal.

Section 2.3.3 Hourmeter Readings

This feature will display the recorded hours of use of the

traction and pump control to the Dash Display each time

the key switch is turned off.

Section 2.3.4 Battery Discharge Indication (BDI)

The latest in microprocessor technology is used to provide

accurate battery state of charge information and to supply

passive and active warning signals to the vehicle operator.

Features and functions:

•

Displays 100 to 0 percent charge.

•

Display blinks with 20% charge. Disables pump circuit

with 10% charge. Auto ranging for 36/48 volt operation.

Adjustable for use on 24 to 80 volts.

Section 2.3.4.a Internal Resistance Compensation

This feature is used when the Battery Discharge Indicator

is present. Adjustment of this function will improve the

accuracy of the BDI.

Section 2.3.5 Handset

This is a multi-functional tool used with the LX, ZX, and SX

Series GE solid state controls. The Handset consists of a

Light Emitting Diode (LED) display and a keyboard for data

entry. Note, for ordering purposes, a separate Handset part

is required for SX controls.

Features and functions:

•

Monitor existing system status codes for both traction

and pump controls. Monitor intermittent random status

codes.

•

Monitor battery state of charge, if available.

•

Monitor hourmeter reading on traction and pump

controls. Monitor or adjust the control functions.

Section 2.3.6 RS 232 Communication Port

This serial communication port can be used with

Interactive Custom Dash Displays to allow changes to

vehicle operating parameters by the operator. Or, it can be

used by service personnel to dump control operating

information and settings into a personal computer program.

Section 2.3.6.a Interactive Dash Display
Modes

The Interactive Custom Dash Display allows the operator to

select the best vehicle performance for changing factory

(task) conditions. There are four (4) "operator interaction

modes" that can be selected by depressing a push button

on the dash display.

From the Dash Display, the operator may select any of four

pre-set interactive modes consisting of (4) Controlled

Acceleration levels, (4) Field Weakening levels and (4)

Speed Limits.

These interactive modes are "pre-set" using the Handset

(Functions 48-63) or a personal computer (Functions 97-

112). This feature allows the operator to select the best

vehicle performance for changing factory (task) conditions.

Section 2.3.7 Circuit Board Coil Driver Modules

Coil drivers are internal to the control card, and are the

power devices that operate the Line, 1A and SP contactor

coils. On command from the control card, these drivers

initiate opening and closing the contactor coils. All driver

modules are equipped with reverse battery protection, such

that, if the battery is connected incorrectly, the contactors

can not be closed electrically.
