3501 Manual — Curtis

The manual emphasizes that the 3501 is a passive device. It does not generate its own voltage; rather, it creates a voltage divider circuit. The motor controller supplies a reference voltage (usually 5V or 10V) to one terminal, a ground to another, and the wiper terminal outputs a varying voltage proportional to pedal position.

A few concepts in the manual deserve special attention because they shape how a machine feels and performs:

Often IP65 or IP67 rated (waterproof and dust-tight). 3. Installation and Wiring

: Features a monochrome 240x128 dot matrix FSTN LCD with backlighting for high visibility. The manual emphasizes that the 3501 is a passive device

Push the meter through the front of the panel cutout. Ensure the alignment is correct and the display is oriented right side up.

The meter records time only when voltage is applied to its input terminals. A quartz crystal oscillator divides time into precise increments. Once recorded, the elapsed hours cannot be reset, ensuring tamper-proof records for warranty, leasing, or maintenance intervals.

: Features an IP65-rated front panel, making it resistant to water and dust in harsh environments.
