Once connected, the programmer will display the controller’s and software revision , confirming communication. The software menus allow you to navigate parameters using keys for scrolling, selecting (Program/Test/Diagnostics), and modifying values. It’s always wise to record factory default values before making changes.
The is a separately excited (SEPEX) motor speed controller designed for a variety of light electric vehicles, most notably Club Car golf carts and other small utility vehicles. Known for providing smooth, silent, and cost-effective control of motor speed and torque, its applications also extend to more demanding industrial settings such as forklifts and Automated Guided Vehicles (AGVs) .
To ensure the longevity of your Curtis 1520 controller, incorporate these routine checks into your vehicle maintenance schedule:
A safety feature that disables the controller if the operator leaves the seat or engages the parking brake. Throttle Types and Configuration
Keep the cooling fins free of debris and dirt to maintain thermal efficiency.
Ensure the mounting surface remains clear of debris to maintain optimal thermal dissipation.
The multi-pin control terminal connects to your vehicle's logic switches, throttle, and safety interlocks. While pin assignments can vary slightly based on OEM customization, a standard Curtis 1520 logic block includes:
Supports 5kΩ 3-wire potentiometers, 0–5V throttles, and electronic throttles. 2. Pinout Configuration and Wiring Diagrams
The controller features heavy-duty stud terminals for the main power and motor connections: Main positive input from the battery bank. B-: Main negative input to the battery bank.
24V or 36V DC (depending on the specific model variant).
