Speed Signal Processing and Input Verification
The module is described as processing pulse signals from magnetic pickups or proximity probes for use in speed control applications. The resulting speed feedback can support governor control and speed monitoring when the module is installed in a compatible system configuration.
Before commissioning, verify the input channel assignments, sensor type, signal amplitude, wiring polarity, and configured speed range against the applicable Woodward hardware documentation. Do not assume that every listed sensor type is supported by every input channel without confirming the module specifications.

Field Installation Guidelines
- Isolate the equipment and follow the site’s lockout and tagout procedures before removing or installing the module.
- Confirm the module part number and hardware revision against the system bill of materials.
- Inspect the connector, chassis slot, and terminals for damage or contamination before installation.
- Route sensor signal cables separately from high-current conductors and switching power cables where practicable.
- Apply cable shielding and grounding according to the manufacturer’s installation instructions. Avoid introducing unintended ground loops.
- Verify sensor polarity, signal integrity, and channel assignment before enabling speed control.
- After installation, check diagnostic indications and compare measured speed feedback with an independent reference before returning the controlled equipment to service.
