BASIC OPERATION AND FEATURES

SX TRANSISTOR CONTROL

Page 7

July 2002

Section 2.3.1.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 2.3.2 Odometer Readings

This feature will display the recorded miles of use of the

traction control to the Dash Display each time the key

switch is turned off.

Section 2.3.3 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.

Section 2.3.4 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.

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 2.3.7 Circuit Board Coil Driver Modules

A Coil driver is internal to the control card, and is the power

device that operate the Line contactor coil. 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.
