GE IC3645SR4R404U2 Installation And Operation Manual

BASIC OPERATION AND FEATURESSX TRANSISTOR CONTROL Page 10October 1998112). This feature allows the operator to select the bestvehicle performance for changing factory (task) conditions.Section 2.3.7 Circuit Board Coil Driver ModulesCoil drivers are internal to the control card, and are thepower devices that operate the Line, 1A and SP contactorcoils. On command from the control card, these driversinitiate opening and closing the contactor coils. All drivermodules are equipped with reverse battery protection, suchthat, if the battery is connected incorrectly, the contactorscan not be closed electrically.Section 2.3.8 Truck Management Module (TMM)The Truck Management Module is a multifunctionaccessory card (IC3645TMM7A), or an integral function ofthe GE Pump controls when used with the SX Tractioncontrol. The Module provides the OEM the ability to initiatestatus codes or operator warning codes to be displayed onthe Dash Display, whenever a normally open switch orsensor wire provides a signal to the Module.The TMM Module can be used to display a separate statuscode indicating over-temperature of traction motors,hydraulic motors, or any other device or system that canactivate a switch that closes.The TMM Module can also be used as a Brush WearIndicator (BWI). The Brush Wear Indicator is designed todetect a "worn out brush" and display a fault code on theDash Display to warn maintenance personnel that themotor brushes need to be replaced before they wear to thepoint of causing destructive damage to the motorcommutator surface.Section 2.4 Hydraulic Pump ControlThis hydraulic motor controller consists of the followingfeatures:•= Four speeds, adjustable from O to 100% motor volts.Fixed speeds actuated by switch closure to negative.•= P1A bypass contactor (if required)•= Variable resistor input (5K-O ohms). Control startswhen input is reduced to below 3.5 volts.•= PMT functions available when a pump contactor isused.•= Current limit and controlled acceleration adjustable.•= Battery Discharge Indicator interrupt compatible.Operation of voltage regulator card: This card provides thebasic functions required for controlling the pump control,optional contactors, and PMT functions. Battery positive isapplied through a main control fuse to the key switch,energizing the control card power supply input to P1.When a pump contactor is used, PMT operation is thesame as outlined for the traction controllers.The four speed (motor volts) reference points P12, P19, P20AND P21 are selected by connecting these pointsindependently to battery negative.The first speed is obtained by closing Speed Limit I (P12) tocontrol negative. SLl is adjustable by Function 11 using theHandset to adjust motor voltage from O to 100%. Thespecified motor volts will be regulated, however, themagnitude of motor current will vary depending on theloading of the vehicle.The second speed is obtained by closing SL2 (P19) tocontrol negative. SL2 is adjusted using the Handset andFunction 12 similar to SL1.The third speed is obtained by closing SL3 (P20) to controlnegative. SL3 is adjusted using the Handset and Function13 similar to SL1.The fourth speed is obtained by closing SL 4 (P21) tocontrol negative. SL4 is adjusted using the Handset andFunction 14 similar to SL1. PIA will close 0.2 seconds aftercontrolled acceleration stops. Speed Limit 4 (Function 14)must be activated and set to >250 to enable the optional P 1A contactor.If more than one Speed Limit is activated, the selectedspeed with the highest motor volts will override the lowmotor volt speed. The current limit circuit is adjustable andoperates the same as the traction current limit.The controlled acceleration circuit is adjustable andoperates the same as the traction circuit. Adjustment rangeis from 0.1 to 5.5 seconds.The variable resistor input will override the fixed motor voltlimits set by the four (4) adjustable Speed Limits. It will varymotor volts above the set limits up to full motor volts, andcloses P1A as resistance is decreased to less than 200ohms.The Battery Discharge Indicator (BDI) interrupt will disablethe hydraulic controller if the connection at P10 loses the12 volt signal from the traction control. BDI interrupt can bedisabled by Function 17 using the Handset. Select card typewith or without BDI function.
