BASIC OPERATION AND FEATURES
SX TRANSISTOR CONTROL
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.
