Accelerator - An electric sensor that replaces the trunnion arm and mechanical linkage function that is found in a traditional hydrostatic drive system.
CAN - Control Area Network, A communication protocol for active components in a system.
Continuity - Is an uninterrupted path from point A to point B.
Contactor - An electromagnetic switch device (a relay) used for switching an electrical circuit.
Deck Controller - The computer controller for the deck motors, reports to the Traction Controller.
Deck Motor - The electric motor that powers the cutting blades.
Digital Display - LCD dash display that communicates system status from the traction controller to the operator.
DMM - Digital Multi-Meter; combination ohm, voltage and current meter.
Drive Motor - The electric motor that powers the gear case.
Electric Current - Is the rate of charge flow past a given point in an electric circuit measured in Amps.
Electric Short - A low resistance connection between two points in an electrical circuit. The current flows through the area of low resistance, bypassing the intended current flow in the circuit.
Integrated Electric Transaxle - The electric motor and gear case assembly that transmits power to the wheels.
NC - Normally closed switch.
NO - Normally open switch.
Ohm Meter - A meter that only measures resistance, measured in ohms.
Resistance - Is the level of opposition to current flow in an electrical system, measured in Ohms.
Smartec Interface Tool - Diagnostic tool for use with the Traction Controller to aide in troubleshooting and repairs.
Smartec ZT 45 Traction Controller - The computer controller for the drive and deck system.
Voltage - Is a measurement of the electrical energy in a circuit at a given point; measured in volts.
Voltage Inverter - An electrical device that converts the system DC voltage to AC voltage.
Wiring Harness - Grouping of conductors (wires) that carry information and electricity.
