Product Description

Woodward ProTech 203 overspeed protection devices are available with a number of power supply options in both energize-to-trip and de-energize-to-trip versions. Model 9905-985 is a de-energize-to-trip version. It has three 120 Vac/dc power supplies, one for each of the three speed-sensing units.

 

Along with individual power supplies, each of these speed-sensing units also has its own operator interface. Units A, B, and C are identical, though they are programmed individually (identical programming is necessary for the correct and safe operation of this system). The units are programmed using the two-line LCD and touchpad on its corresponding interface.

 

To switch between MONITOR and PROGRAM modes, users must use a key to unlock the enclosure. When the optional stainless steel hubs are used, this enclosure is NEMA 4X certified. Tunable parameters and programming instructions are thoroughly outlined in Woodward’s ProTech 203 manual 85195.

 

This manual also has information on features of model 9905-985, such as hot replacement, the built-in self-test, remote reset, and available functional status indicators and alarm outputs.

 

Manual 85195 also contains basic location considerations that must be taken into account before installing the ProTech 203 9905-985 model. This overspeed protection device is sensitive to many factors, like vibration, heat, and moisture, and a proper location is necessary to ensure the safe and accurate operation of this device.
