Woodward 8440-1935 easYgen-3500-1-P1 Controller

Woodward 8440-1935 easYgen-3500-1-P1 Controller

Key Technical Specifications at a Glance

The 8440-1935 belongs to Woodward’s easYgen-3000 family. This model is also known as easYgen-3500-1-P1. It provides an accuracy class of 0.5 for reliable measurement. The resolution reaches 16-bit, ensuring precise data capture. Setting range for current spans from 1 up to 32,000 A.

Isolated discrete inputs come standard on this unit. Front panel dimensions are 282W x 216H x 96D mm. The chassis uses sheet metal for durability. Weight is approximately 1,850 g. Therefore, it suits permanent cabinet installation well.

Power Factor and Electrical Characteristics

The 8440-1935 includes a power factor feature. This factor represents the ratio of real power to apparent power. Three circuit types work with the power factor. These are capacitive, purely resistive, and inductive circuits.

For a purely resistive circuit, current and voltage waveforms stay in step. The power factor equals 1.00 in this case. Engineers often call this condition "unity." Understanding this helps you optimize generator performance.

Important Safety and Installation Instructions

Install this controller inside a cabinet. Do not connect any wires to the protective earth terminal on the controller itself. If you need a protective earth connection, use the connector at the bottom of the 8440-1935.

Additionally, always short-circuit the current transformer before disconnecting the device. Failure to short-circuit the transformer may cause severe personal injury or death. Therefore, follow this safety step without exception.

Integrated Breaker Control and Mechanical Mounting

The easYgen-3500 models feature integrated generator group breaker control. This simplifies your system design. First, mount the 8440-1935 securely inside the cabinet. Ensure adequate space for ventilation and wiring access.

Next, connect all discrete inputs using isolated wiring practices. Finally, configure the current setting range according to your CT ratings. The 1-32,000 A range covers most industrial applications.

Frequently Asked Questions (FAQ)

1. Can I mount the Woodward 8440-1935 on a front panel?
No, this model uses a sheet metal chassis for inside-cabinet mounting only.

2. What happens if I do not short-circuit the current transformer?
It can cause severe personal injury or death. Always short-circuit the CT before disconnection.

3. Where should I connect the protective earth wire?
Use the dedicated connector on the bottom of the 8440-1935. Do not use the terminal on the controller body.

4. What is the unity power factor condition?
Unity occurs with a purely resistive circuit where voltage and current waveforms stay in step, giving a factor of 1.00.

5. Does this unit support remote panel operation?
The 8440-1935 focuses on cabinet-mounted gen-set control with integrated breaker control. Remote panel features are not primary for this variant.
