Curtis 3501 Manual Official

Allow the unit to cool down. Check the thermal paste layer and verify that the mounting surface is not exposed to external heat sources. Ensure the duty cycle of the vehicle is within operational parameters. Code 1,2: Throttle Fault (HPD)

The Curtis 3501 manual covers a wide range of topics, including:

: Toggle unit values across speed, distance, or thermal readings.

500 VAC (minimum) from the electronics chassis to the heat sink aluminum plate. Storage Temperature Range: -40°C to 85°C. Operating Temperature Range: -25°C to 50°C. 2. Installation and Mechanical Mounting curtis 3501 manual

Connected between the wiper input and the low reference. The controller must be programmed specifically to recognize a 2-wire setup to prevent "Open Throttle" safety faults. 3. Volt Throttles (0–5V or Hall Effect)

Solenoid contacts welded, stuck open, or coil wire disconnected.

: Pin 1 (SCI Rx), Pin 3 (CAN_L), Pin 7 (KSI - Key Switch Input), and Pin 8 (MOSFET Output) are critical for primary wiring. Allow the unit to cool down

Provides full control over motoring and regenerative braking in both forward and reverse directions.

You must assume that any vehicle you service could move unexpectedly. follow this protocol:

Ensure Pin 3 (Signal) is receiving the correct voltage. Most units require a high signal to trigger the timer. Code 1,2: Throttle Fault (HPD) The Curtis 3501

Connections are routed through a singular 16-pin Tyco mating connection block. Pin allocations must be paired precisely with matching wire gauges to avoid data drops or short circuits.

Controller internal temperature has exceeded 85°C or dropped below -25°C.

Providing alerts when service intervals are reached. 2. Technical Specifications
