ELECTRICAL SYSTEM BATTERIES If your machine shipped with batteries installed do the following: • Check that the batteries are connected to the machine (7). • Turn ON the Key Switch (AA) and check the Battery Indicator (BB). If the green light is ON, the batteries are ready for use. If the green light is OFF, the batteries should be charged before use.
ELECTRICAL SYSTEM CHARGING THE BATTERIES Charge the batteries each time the machine is used for 1 hour or longer, or whenever the Battery Condition Indicator Lights (BB) light up red. To Charge the Batteries... IMPORTANT!: Open the Battery Compartment Cover (13) to provide proper ventilation. Disconnect the Battery Connector Assembly (7) and plug the battery charger into the plug connected to the batteries.

ELECTRICAL SYSTEM CURTIS CONTROLLER DIAGNOSTICS: Diagnostics Method A: Uses the machine’s control display LED panel and Horn Indicator Light (FF). FUNCTION OF THE SPEED CONTROLLER STATUS LIGHT AND DISPLAY The Curtis 1228 (36V) speed control will output a fault code if there is a problem associated with the speed control and wheel drive system. See Figure 6.
ELECTRICAL SYSTEM STATUS LED FAULT CODES (TABLE 1) STATUS LIGHT EXPLANATION POSSIBLE CAUSE CODE DISPLAY over-/under-temperature cutback 1. Temperature >92°C or < -25°C. 2. Excessive load on vehicle 3. Operation in extreme environments. 4. Electromagnetic brake not releasing. 0 00 throttle fault 1.
ELECTRICAL SYSTEM INSTALLATION CHECKOUT FOR THE CURTIS SPEED CONTROLLER SAFETY! The 1228 controller is inherently a high power device. When working around any battery powered vehicle, proper safety precautions should be taken. These include, but are not limited to: proper training, wearing eye protection, avoiding loose clothing and jewelry, and using insulated wrenches.
ELECTRICAL SYSTEM FUNCTIONAL OVERVIEW OF MAIN CONTROL BOARD The primary function of the main control board A1 is to position the burnishing pad with respect to the fl oor surface using a lift actuator motor to maintain the correct pad pressure and current draw of the pad motor. When the pad drive switch (EE) is depressed this will lower the pad deck to the operating position and by activating the drive pedal start the pad motor.
ELECTRICAL SYSTEM ADVOLUTION PROGRAMMING MODES Fault Recall Mode / Revision Display: Whenever an electrical system fault is detected by the main control unit, one or more error codes are displayed and stored by the control unit. If it is desired, the error code (if any) from the previous operation of the machine can be recalled for troubleshooting purposes. To recall the last stored error codes perform the following steps: Press and hold the horn switch while turning the key switch on.
ELECTRICAL SYSTEM ADVOLUTION PROGRAMMING MODES Status Display: If no over-current faults are present, the status display will show the battery voltage. This display is accurate to within +/- 0.15 volts. Therefore, the voltage displayed may not correlate precisely to a high-accuracy, calibrated voltmeter. The leftmost digit of the display is used to indicate the state of the seat switch and the deck interlock switch inputs.
ELECTRICAL SYSTEM ADVOLUTION PROGRAMMING MODES Low Voltage Cutout Threshold Selection Mode: FACTORY DEFAULT: STD The Advolution is equipped with a low voltage cutout feature to prevent over-discharging the batteries. This feature will automatically shut down the pad motor when the battery voltage falls to the selected threshold. The cutout level is adjustable. The standard setting is 31.5 volts (1.75 volts per cell) and the alternate setting is 33.12 volts (1.84 volts per cell).
ELECTRICAL SYSTEM ADVOLUTION PROGRAMMING MODES Forward Motion Alarm Volume Level Adjustment Mode: FACTORY DEFAULT: 0 (OFF) The control system has the ability to activate a forward alarm signal to alert personnel of the approach of the machine. The volume of this alarm is adjustable from 0 to 9.
ELECTRICAL SYSTEM TROUBLESHOOTING GUIDE Symptom No machine functions work. (control circuit) Machines without onboard battery charger. Note :Do all testing with the 5 amp circuit breaker reset, key switch on, emergency switch closed and seat switch activated.
