Wiring and Installation

Mounting the Controller

The controller can be oriented in any position which should be as clean and dry as possible, if necessary, shielded with a cover to protect it from water and contaminants.

To ensure full rated output power, the controller should be fastened to a clean, flat metal surface with four or six screws. Applying silicon grease or some other thermal conductive material to contact surface will enhance thermal performance.

Proper heat sinking and airflow are vital to achieve the full power capability of the controller.

The case outline and mounting holes‟ dimensions are shown in Figure 1 and 2.

Caution:

• RUNAWAYS — Some conditions could cause the vehicle to run out of control. Disconnect the motor, or jack up the vehicle, and get the drive wheels off the ground before attempting any work on the motor control circuitry.
• HIGH CURRENT ARCS — Electric vehicle batteries can supply very high power, and arcs can occur if they are short circuit. Always turn off the battery circuit before working on the motor control circuit. Wear safety glasses, and use properly insulated tools to prevent short circuit.

Connections

Front and Back Panels of PM Motor Controller:
Four metal bars and two plugs (J1, J2) are provided for connecting to the battery, motor and control signals in the front and back panels of the controller shown as Figure 3 and 4

Notes:

1. All RTN and GND pins are internally connected, but isolated from B-.
2. Two PWR pins, J1-1 and J2-1, are internally connected. It’s recommended to use J1-1 to supply peripherals like alarm and contactor. Twist peripheral wires with PWR is the preferred for EMC.
3.  Kelly Ammeter positive connect to 5V power supply of controller, negative to J1-  4. Switch to ground is active. Open switch is inactive

Caution:

• Do not apply power until you are certain the controller wiring is correct and has been double checked. Wiring faults will damage the controller.
  

• Ensure that the B- wiring is securely and properly connected before applying power.
  

• The preferred connection of the system contactor or circuit breaker is in series with the B+ line.
  

• All contactors or circuit breakers in the B+ line must have precharge resistors across their contacts. Lack of even one of these precharge resistors may severely damage the controller at switch-on.

Installation Checklist
Before operating the vehicle, complete the following checkout procedures. Use LED code as a reference as listed in Table 1.

Caution:

• Put the vehicle up on blocks to get the drive wheels off the ground before beginning these tests.
  

• Do not allow anyone to stand directly in front of or behind the vehicle during the checkout.
  

• Make sure the PWR switch and the brake is off
  

• Use well-insulated tools.

• Make sure the wire is connected correctly.

• Turn on the PWR switch, the Red flashes once and the Green is off. After the start-up delay, normally the Red will stay off and the Green will turn on. If there is error, the Red LED will flashes for fault codes. If the S/N less: 11xxxxxx: Turn on the PWR switch, the Red flashes once and the Green is on. Normally, the Red will stay off. If there is error, the Red LED will flashes for fault codes.

• The fault code will be detected automatically at restart.

• With the brake switch open, select a direction and operate the throttle. The motor should spin in the selected direction. Verify wiring or voltage and the fuse if it does not. The motor should run faster with increasing throttle. If not, refer to the Table 1 LED code, and correct the fault as determined by the fault code.

• Take the vehicle off the blocks and drive it in a clear area. It should have smooth acceleration and good top speed.

Maintenance

There are no user-serviceable parts inside the controllers. Do not attempt to open the controller as this will void your warranty. However, periodic, exterior cleaning of the controller should be carried out.

The controller is a high powered device. When working with any battery powered vehicle, proper safety precautions should be taken that include, but are not limited to, proper training, wearing eye protection, avoidance of loose clothing, hair and jewelry. Always use insulated tools.

Cleaning

Although the controller requires virtually no maintenance after properly installation, the
following minor maintenance is recommended in certain applications.

• Remove power by disconnecting the battery, starting with battery positive, providing that the battery negative is not earthed. If battery negative is earthed, disconnect that first.
• Discharge the capacitors in the controller by connecting a load (such as a contactor coil, resistor or a horn) across the controller‟s B+ and B- terminals.
• Remove any dirt or corrosion from the bus bar area. The controller should be wiped down with a moist rag. Make sure that the controller is dry before reconnecting the battery.
• Make sure the connections to the bus bars, if fitted, are tight. To avoid physically stressing the bus bars use two, well-insulated wrenches

Configuration
You can configure the controller with a host computer through either an RS232 or USB port

• Disconnect motor wiring from controller.
• Do not connect B+, throttle and so on. The controller may display fault code in some conditions, but it doesn’t affect programming or configuration.
• Use a straight through RS232 cable or Kelly USB To RS232 Converter to connect to a host computer. Provide 8V-20V (either J2 pin1 or J1 pin1) to PWR. Wire power supply return to any RTN pin, isolated from B-.
