BASIC OPERATION AND FEATURESIT400 TRANSISTOR CONTROL Page 8January 2008however, the resulting PMT should open the Linecontactor, in the event of a failure.Section 2.3 DiagnosticsSection 2.3.1 Systems DiagnosticsThe control detects the system's present operatingstatus and can be displayed to either the DashDisplay or the Handset. There are currently over 70status codes that are available with IT systems usingTraction and Pump controls and Truck ManagementModule (TMM). Along with the status code displayfrom the TMM, the IT control is capable of reducingthe current to the motor, alerting the operator of acritical fault condition.Section 2.3.2 Status CodesSection 2.3.2a Standard Status CodesThe IT traction control has over 30 Status Codes thatassist the service technician and operator in troubleshooting the vehicle. If mis-operation of the vehicleoccurs, a status code will be displayed on the DashDisplay for vehicles so equipped, or be available byplugging the Handset into the “y” plug of the logiccard.With the status code number, follow the proceduresoutlined in DIAGNOSTIC STATUS CODES todetermine the problem and a solution.Note: The Status Code Instruction Sheets do notclaim to cover all possible causes of a display of a"status code ". They do provide instructions forchecking the most direct inputs that can cause statuscodes to appear.Section 2.3.2.b Stored Status CodesThis feature records the last 16 "Stored StatusCodes" that have caused a PMT controller shut downand/or disrupted normal vehicle operation. (PMT typefaults are reset by cycling the key switch). Thesestatus codes, along with the corresponding BDI andhourmeter readings, can be accessed with theHandset, or by using the RS 232 communicationsport and dumping the information to a PersonalComputer terminal.Section 2.3.3 Hourmeter ReadingsThis feature will display the recorded hours of use ofthe traction and pump control to the Dash Displayeach time the key switch is turned off.Section 2.3.4 Battery Discharge Indication (BDI)The latest in microprocessor technology is used toprovide accurate battery state of charge informationand to supply passive and active warning signals tothe vehicle operator. Features and functions:• Displays 100 to 0 percent charge.• Display blinks with 20% charge. Disables pumpcircuit with 10% charge. Auto ranging for 36/48volt operation. Adjustable for use on 24 to 80volts.Section 2.3.4.a Internal Resistance CompensationThis feature is used when the Battery DischargeIndicator is present. Adjustment of this function willimprove the accuracy of the BDI.Section 2.3.5 HandsetThis is a multi-functional tool used with the LX, ZX,SX and IT Series GE solid state controls. TheHandset consists of a Light Emitting Diode (LED)display and a keyboard for data entry. Note, forordering purposes, a separate Handset part isrequired for IT controls.Features and functions:• Monitor existing system status codes for bothtraction and pump controls. Monitor intermittentrandom status codes.• Monitor battery state of charge, if available.• Monitor hourmeter reading on traction and pumpcontrols. Monitor or adjust the control functions.Section 2.3.6 RS 232 Communication PortThis serial communication port can be used withInteractive Custom Dash Displays to allow changesto vehicle operating parameters by the operator. Or,it can be used by service personnel to dump controloperating information and settings into a personalcomputer program.Section 2.3.6.a Performance Mode SelectionManipulation of SW1 and SW2 allows the operator toselect the best vehicle performance for changing taskconditions or performance modes. There are four (4)"operator interaction modes" that can be activated byadjustment of Function 17, and manipulation of SW1and SW2.The operator may select any of four pre-setinteractive modes consisting of (4) ControlledAcceleration levels, (4) Regen Current levels, (4) Min
