1. Setup and Installation

Proper setup is crucial for the optimal performance and longevity of your motor controller. Ensure all connections are secure and follow the wiring diagram carefully.

1.1 Throttle Configuration

The controller supports ten different throttle types. It is essential to configure the controller to match your vehicle's specific throttle type. Please contact the seller after purchase to specify your required throttle configuration. The available throttle types include:

• Type 0: 2-wire potentiometer, 0-5kΩ
• Type 1: 2-wire potentiometer, 5kΩ-0
• Type 2: Single-ended 0-5V input
• Type 3: 2-wire potentiometer, 4.6kΩ-0
• Type 4: 2-wire potentiometer, 5.5kΩ-0
• Type 5: 2-wire potentiometer, 1kΩ-0
• Type 6: ITS input
• Type 7: Single-ended 6.3-10.6V input
• Type 8: Single-ended 6-12V input
• Type 9: 3-wire potentiometer, 0-5kΩ

1.2 Voltage Confirmation

The controller requires an exact voltage value for proper operation, not a range. Please confirm your system's voltage and communicate it to the seller after purchase for correct pre-delivery configuration.

1.3 Wiring Diagram

Refer to the following diagram for correct wiring connections. Incorrect wiring can damage the controller or connected components.

Figure 2: Wiring Diagram. This diagram illustrates the connections for the motor controller, including power, motor armature, motor field, keyswitch, interlocks, pedal microswitch, and throttle input. It also shows polarity protection and precharge resistor circuits.

2. Operating Instructions

Once properly installed and configured, the Cotether 1205-101 motor controller facilitates precise control over your DC series motor. Ensure all safety precautions are observed during operation.

2.1 Power On/Off

• To Power On: Ensure all connections are secure. Turn the keyswitch to the 'ON' position. The controller will perform a self-diagnostic check.
• To Power Off: Turn the keyswitch to the 'OFF' position. Allow the system to fully shut down before disconnecting any power sources.

2.2 Motor Control

The motor speed and direction are controlled via the connected throttle and forward/reverse switches, as indicated in the wiring diagram. Gradual application of the throttle is recommended for smooth operation and to prevent sudden surges.

• Acceleration: Increase throttle input gradually.
• Deceleration: Reduce throttle input.
• Direction Change: Ensure the vehicle is stationary before changing direction (Forward/Reverse) to prevent damage to the motor or controller.

3. Maintenance

Regular maintenance ensures the longevity and reliable performance of your Cotether motor controller.

• Cleaning: Keep the controller free from dust, dirt, and moisture. Use a dry, soft cloth for cleaning. Do not use solvents or abrasive cleaners.
• Connections: Periodically check all electrical connections for tightness and corrosion. Loose connections can lead to overheating and intermittent operation.
• Environmental Conditions: Ensure the controller operates within its specified temperature and humidity ranges. Avoid exposing it to extreme conditions.
• Inspection: Visually inspect the controller for any signs of physical damage, such as cracks, bulges, or discoloration.

4. Troubleshooting

This section provides guidance for common issues. For complex problems, contact technical support.

4.1 Common Issues and Solutions

• Motor Not Responding:
  • Check power supply connections and battery voltage.
  • Verify keyswitch is in the 'ON' position.
  • Inspect throttle connections and functionality.
  • Ensure interlocks (if present) are engaged correctly.
  • Check for blown fuses in the control or power wiring.
• Intermittent Operation:
  • Examine all wiring for loose or corroded connections.
  • Check for signs of overheating on the controller or motor.
• Motor Runs Only in One Direction:
  • Verify the forward/reverse switch and its wiring.

If troubleshooting steps do not resolve the issue, contact Cotether customer support for further assistance.
