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 2.3.3.a Maintenance Alert & Speed Limit 
 

This feature is used to display Status Code  99 and/or 

activate a speed limit when the vehicle operating hours 

match the hours set into the maintenance alert register. 

This feature is set with the Handset using Functions 19 and  

20. The operator is alerted that maintenance on the vehicle 

is required. 

 
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 48-62) 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 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. 

 

Section 2.3.8 Truck Management Module (TMM) 
 

The Truck Management Module is a multifunction 

accessory card, or an integral function of the GE Pump 

controls when used with the SX Traction control. The 

Module provides the OEM the ability to initiate status codes 

or operator warning codes to be displayed on the Dash 

Display, whenever a normally open switch or sensor wire 

provides a signal to the Module. 

 

The TMM Module can be used to display a separate status 

code indicating over-temperature of traction motors, 

hydraulic motors, or any other device or system that can 

activate a switch that closes. 

 

The TMM Module can also be used as a Brush Wear 

Indicator (BWI). The Brush Wear Indicator is designed to 

detect a "worn out brush" and display a fault code on the 

Dash Display to warn maintenance personnel that the 

motor brushes need to be replaced before they wear to the 

point of causing destructive damage to the motor 

commutator surface. 

 
Section 2.4  Hydraulic Pump Control 
 

This hydraulic motor controller consists of the following 

features:
