CT-302S9 Controller for Electric Scooter
Operation Instructions
--Performance and Features--
1. High efficiency, low heat generation, capable of working normally for about 180 seconds when the 200W motor is blocked and for 150 seconds when the 250W motor is blocked.
2. Provided with the following protection circuits:
1) Current limiting: This prevents the motor current from exceeding the specified value thus avoids damage to the motor and the controller due to over-current.
2) Battery under-voltage protection: When battery voltage lowers to specified value, the controller automatically cuts off the battery output so over-discharge is avoided, thus longer battery life of cyclic use.
3) Power cut-off during braking: The brake switch makes when braking is underway. A signal is fed to the controller, which in turn cuts off battery output automatically.
4) Over-speed prevention during electric charging: During charging of the battery, the controller renders the speed adjusting turn handle temporarily inoperable, preventing over-speed due to mistaken manipulation.
3. Epoxy capsulated, thus moisture proof, water splash proof and shock proof.
4. Suspended terminal easy of connection and reliable.

 

--Technical Parameters --

Note: Interface output voltage for power indicator and brake indicator may be customized.
Note: Interface output voltage for speedometer, power indicator and brake indicator may be customized.
-- Installation and Wring --
1. Power lines (with DJ7022-6.3-11 connecting plug)(电源线)
2. Motor output lines (with DJ7022-6.3-21 connecting plug)(电机输出线)
3. Brake signal line and speed adjusting signal line (with DJ7061A-2.8-21 connecting plug )
4. Interface for electric door lock (with DJ7031A-2.8-11 connecting plug): 1007 #20 wire(电门锁接口)

电门锁回路串接的保险管为5A,当电池电机回路以外的负载短路时,保险丝融断,保护控制器不被损坏。此时只需将短路故障排除,更换相同容量的保险管即可。
5. Interface for electric charger (with DJ7021A-2.8-21 connecting plug) (充电器接口)
6. Interface for power indicator (with EL-2P male plug) 电源灯接口
7. Interface for brake indicator (with DJ7021A-2.8-11 connecting plug) (刹车灯接口)
----Precautions---使用注意事项
1. Ascertain that rated voltage of the controller corresponds to the nominal voltage of the battery.
2. When wiring is made, always match male and female terminals and colour of wire. After connecting a plug to a socket, use heat shrinkage tube or tape to fix.
3. The red positive power line and the black earth wire shall not be inverted between each other, otherwise the controller is damaged!! Recommended wiring procedure: connect the earth and other wires first, and only after such wiring is ascertained as correct may the positive power line be connected.
4. Should there be any difference of the present Operation Instructions from the previous operations instructions for CT-301A9, the present edition will govern.
