Functional Description

5462-718 is a Speed Sensor Board developed by Woodward. The Speed Sensor Board incorporates sophisticated signal processing circuitry, which amplifies, filters, and processes the speed signals received from the sensors. This ensures precise and stable speed measurements, even in challenging operating conditions.

Features

• It is not advised to use gears mounted on an auxiliary shaft coupled to the rotor to sense speed. Auxiliary shafts turn slower than the rotor, reducing speed sensing resolution, and have coupling gear backlash, resulting in less-than-optimal speed control. It is also not recommended for safety reasons that the speed sensing device sense speed from a gear coupled to a mechanical drive side of a system's rotor coupling.
• Speed Sensor Input Faults - To detect input faults, the application software may set a high and low latch setpoint. The low latch setpoint must be greater than half the frequency range.
• The MPU and proximity probe inputs are read, and the application program is given the speed. If desired, the application software provides a derivative output. The Analog Combo module filters the speed sensor inputs, and the filter time constant is selectable via the application software program at 8 milliseconds or 16 milliseconds.

Speed Sensor Inputs MPUs

• Check that the cable is shielded and that the shield is properly grounded.
• On the terminal block, measure the input voltage. It should be between 1 and 25 VRMS.
• Check that the signal waveform is free of double zero crossings.
• Check that there is no ground connection and that the resulting 60 Hz signal is not present.
• Calculate the frequency. It should be in the 100 Hz - 25 kHz range.
• Examine the individual inputs to each kernel. If the terminal block jumpers are installed, A and B should read an input, and C should also read this input. Three distinct numbers, one from each module, should be included in the application software. Except for kernel C if the jumpers are not installed, the numbers should be within 0.1% of each other.

Frequently Asked Questions

What is 5462-718?
It is Speed Sensor Board developed by Woodward.

Why is it not recommended to sense speed from a gear coupled to the mechanical drive side of a rotor coupling?
Sensing speed from a gear coupled to the mechanical drive side of a rotor coupling is not recommended for safety reasons. It is important to avoid sensing speed from this location to prevent any potential hazards or risks associated with the mechanical drive side of the system.

How are speed sensor input faults detected?
To detect input faults, the application software can utilize high and low latch setpoints. The low latch setpoint must be set greater than half the frequency range to accurately identify any input faults.
