3.3. Installation Check List
Before operating the motor and the vehicle, complete the following checkout procedures. Use the LED indicator codes as the reference. LED codes are listed in Table 1 and 2.
WARNING: Regeneration has braking effect, but cannot replace mechanical brake. Mechanical brake is required to stop your vehicle. Regeneration is NOT a safety feature! Controller may stop regeneration to protect itself, NOT YOU!
WARNING: Make sure that all connections are correct before applying e lectrical input; otherwise it may damage the controller! Securely wire B- before applying power. It is preferred to mount a load relay on B+, and place a pre-charge resistor on any breaker.
WARNING: Get the drive wheels of the vehicle off the ground before beginning the tests. DO NOT let anyone to stand in front of or behind the vehicle during the check out. Make sure that both the PWR switch and brake are off. Use well-insulated tools.
Turn the PWR switch on. The LED should blink, and then keep on when the controller operates normally. If this does not happen, check the continuity of the PWR and controller ground. The fault code will be detected automatically at restarting. With the brake switch open, select a direction and operate the throttle. The motor should spin in the selected direction. Please verify wiring and voltage if does not operate. Also, check fuse. The motor should run faster with increasing throttle. If no, refer to LED Codes Table 2, and correct the fault according to the code. Take the vehicle off the blocks and drive it in a clear area. It should have smooth acceleration and good top speed.

4. MAINTENANCE OF MOTOR CONTROLLER If the controller stops working, hand in to TEKNOLUS for repair. Do not attempt to open the controller; otherwise you may damage it irreparably. However, cleaning the controller exterior periodically may be necessary. The controller is inherently a high power d evice, so working with any battery powered vehicle needs proper safety precautions and training. These include, but are not limited to: proper training, wearing eye protection, avoiding loose clothing and jewelry, and using insulated tools.
4.1.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. Discharge the capacitors inside the controller by connecting a load (such as a contactor coil or a horn) across the B+ and B- terminals. Remove any dirt or corrosion form the bus bar area. The controller should be wiped down with a moist rag. Please be sure that the controller is dry before reconnecting the battery. Make sure the connections to the bus bars are tight. Use two wrenches for this task in order to avoid stressing the bus bars. The wrenches must be well insulated.
4.2.Configuration
The controller can be configured with a host computer through RS232 or USB po rt.
Use straight RS232 cable or Teknolus Standard USB to RS 232 Converter to connect the nine pinned connector on face panel to a host computer. Provide 18 – 90V to PWR. Wire power supply ground to any RTN pin. Do not connect B+, throttle and so on. The controller may display fault code in some conditions, but it does not affect programming or configuration.

5. TECHNICAL SPECIFICATIONS OF MAST30S HUB MOTOR SERIES MAST 30S series motors are used as a source of motive power in numerous applications from industrial automotization to wind turbines. They are also great for EV hacking and conversion. In-wheel drive electric motors (hub motors) represent an effective method of providing propulsion to vehicles which otherwise were not designed to have driven wheels. MAST Hub motors are compact and modular, require no support of rotating axles from the parent vehicle, and can be designed around the vehicle to be propelled. Hub motor electromagnetic fields are supplied to the stationary windings of the motor. The outer part of the motor f ollows, or tries to follow, those fields, turning the attached wheel. This makes hub motors more eff icient and more powerful than the ordinary electric motors. Below, the technical datasheet of Mast 30S hub motor is given. Then motor characteristic curves are presented.
