SEVCON MOTOR SPEED CONTROLLER The Sevcon Motor Speed Controller (MC-) is a microprocessor designed with the express purpose of operating the D/C electric motor at varying speeds. The controller uses Pulse-Width Modulation (PWM) technology on the Ground side of the motor to control motor speed. Out of concern for operator safety and to prevent short-circuiting, the Controller monitors certain circuits for potential abnormalities. When the controller senses a problem it errs to the side of safety and stops all motor operation. The green LED will flash a code indicating the reason for the shutdown. Refer to the LED Diagnostics Definitions and Sevcon Motor Speed Controller - Connections on the following pages.

LED Diagnostics Definitions (Flash Codes) LED READING LED Steady On LED Off Flashes Flashes 4 Flashes 5 Flashes DIAGNOSIS Controller is operational and detects no irregularities on monitored circuits. No power-up No power to pin #. No ground to B- post. LED failure or internal controller fault. Procedure fault. Enable depressed at power up. Enable depressed for more then 5 seconds without function request. No signal on wire 7 pin # when function requested. No B- to diode board. Failed diode/s. Damaged wire harness. Internal controller fault. Motor circuit low. Set with unit at rest and is the result of the voltage at M- dropping to approximately 4 volts or lower. Possible causes: Short to ground in the motor circuit between the motor contactor and the M- terminal. Motor circuit high. Set with the unit at rest and is the result of the voltage at M- terminal rising above volts. Possible causes: Motor contactor points are welded shut Motor contactor circuit open. Set when a function is requested but no current can flow through the motor circuit to the M- terminal. Possible causes: Blown 00 amp fuse Malfunctioning motor contactor Worn motor brushes Incomplete circuit to the Sevcon pin # If the motor and contactor circuits are diagnosed as working properly: Sevcon internal fault continued "047ES / 47ES / 47ES" Service & Parts Manual - ANSI Specifications March 008 Page 4-5
LED Diagnostics Definitions (continued) LED READING Flashes 7 Flashes 8 Flashes Flashes DIAGNOSIS Accelerator fault. Set with unit at rest, a flash will result in an 80% cutback of motor speed. The Accelerator is the proportional control circuitry for the Sevcon. It works in conjunction with the potentiometer located in the upper control box, which is connected to the joystick handle through a gear arrangement. Measure voltage at terminals 4 and 5 on the platform terminal strip or at the potentiometer plug connection. With the joystick handle in neutral,. volts should be measured on the accelerator circuit (wire #4). Voltage proportionally decreases with the travel of the joystick, with 0 volts at full stroke. With the joystick centered, voltages lower than. or higher than. will trigger a ( flash) code. Battery voltage fault. This includes battery voltage below volts or above 45 volts as measured on pin #. This code will disable all functions. Thermal cutback. Sevcon internal temperatures above 7 degrees F. Will limit motor speed in comparison with over temperature. Resets when cooled. Battery voltage at or below 8 volts As measured on pin #. This code will interrupt or prevent lift function but will allow drive and steer functions. When lift is interrupted due to a flash, the electric motor will still run. March 008 Page 4- "047ES / 47ES / 47ES" Service & Parts Manual - ANSI Specifications
Sevcon Motor Speed Controller - Connections The following two pages describe the connections to the Sevcon Motor Speed Controller with a brief description of their function and the voltage measurements under normal conditions. Important: Batteries must be fully charged before troubleshooting! A fully charged battery set on a 4 V DC system will have a nominal voltage of 5. V DC FUNCTION VOLTAGE READING PIN WIRE (WIRE ON EARLY UNITS) Battery Positive Input Pin Wire 7 Lift, Drive or Steer functions requested Switched 5% less than battery voltage Controller power-up and reference point for battery state-of-charge. Green LED indicates controller power-up. Power travels through the upper emergency-stop switch with upper controls selected. 7-Flash code and -flash code indicate low voltage at this terminal. Motorized function is requested 5%-8% less than battery voltage Controller begins the motor run sequence with this signal but still requires a signal on pin 4 and a change on pin before the motor will operate. Pin Wire 8 Steer Function Requested Pin 4 Wire Enable signal input Pin 5 Wire Speed cutback signal from limit switch or Lift circuit When steering is operated 5%-8% less than battery voltage Adds motor speed to compensate for addition of steer requirement during drive operation. Provides a minimum motor speed for steer requirement when only steer is operated. When joystick trigger pulled 5% less than battery voltage. Motor will not start without this input A signal here longer then 5 seconds without a signal on pin- or pin- will result in a -flash code failure. Full speed: 4 V DC Creep speed: 0 V DC. Speed cutback is the elevated drive speed. "047ES / 47ES / 47ES" Service & Parts Manual - ANSI Specifications March 008 Page 4-7

This is how the Controller maintains control over the motor circuit. Sevcon controls the Motor Start Relay function ground signal. Will not operate the motor start relay when,, 4 & 7 flash codes occur. 0 volts No ground presence until lift is requested. By providing the ground signal, lift function can be prevented anytime battery voltage falls below 8 volts. This will result in a flash code. From.5 V DC with joystick in the neutral to 0 V DC at full stroke. Controller uses this circuit to monitor joystick input after pins & 4 energize. Controls motor speed in reference to the voltage on this circuit. Voltages above 4.0 V DC or below.0 V DC will result in a flash code. Full battery voltage. No real diagnostic value. Battery ground cable connection Ground path for motor operation All system ground wires (wire #s 5 & 5A) terminate here. Best place to connect ground lead from multimeter while troubleshooting. Idle: V DC V DC During operation, between 5 V DC & 4 V DC. volts is reference voltage used by the controller to monitor motor circuit irregularities at idle. 0 volts at idle = flash code Above 0 volts at idle = 4 flash code No voltage change after Motor Start Relay signal = 5 flash code.
