Standard switches that dictate motor directional logic.
Regular maintenance and repair are essential to extend the lifespan of the Curtis 1520 controller and ensure optimal performance. Here are some general guidelines:
The 1520 controller parameters can be customized for specific applications using a Curtis programmer . Key Adjustable Parameters Sets the time from zero to full speed. Maximum Speed: Defines the top speed limit.
Connects to the negative armature terminal of the motor. Low-Current Control Connections curtis 1520 controller manual
Are you currently seeing a specific on your programmer or LED?
The throttle signal is outside the programmed range. Check for loose wires or a faulty potentiometer.
Proper wiring is critical to prevent permanent damage to the controller internal MOSFETs. The Curtis 1520 features a low-current logic connector alongside heavy-duty high-current busbars.

Elevate the drive wheels off the ground to prevent accidental movement during initial testing.
Clean a flat, unpainted metal surface to mount the controller. This acts as a heat sink.
The Curtis 1520 is a high-performance, programmable motor speed controller designed for industrial electric vehicles. Commonly found in walkie stackers, pallet jacks, and small utility vehicles, this controller manages permanent magnet DC motors.
(depending on the specific manufacturer variant) to resist harsh environmental conditions. Installation & Troubleshooting Tips
Proper wiring is critical for both the high-current power circuit and the low-current control circuit. Incorrect wiring can instantly destroy the controller.
