Product Change Notification 06946A

Overview

In January, 2018. Woodward released new ProTech-GII models and a Field Software Conversion

kit. The new models include the same functionality as the older ProTech-GII models but with

many product improvements and enhancements. Woodward recommends that customers who

are purchasing ProTech-GII units for use in new applications order part numbers from the “new”

part number list only. Refer to product manual 35086 for detailed product information.

Customers with older ProTech GII models (Rev D or later) may use the new Field Software

Conversion kit to upgrade/convert their units to the new ProTech-GII models. Manual 51582

describes the conversion process.

Description of Changes

The new ProTech-GII software program is based on the older ProTech-GII software program and

includes the below listed improvements/enhancements.

• Speed Loss (sudden speed loss): The failure threshold was made configurable and the fault

action was expanded to include a selection of ‘not used’.

• Increased allowable ranges for speed settings from 32000 to 80000 rpm to facilitate turbo

expander applications. The maximum speed frequency remains at 32 kHz.

• A configurable low-pass filter was added to the acceleration signal.

• Chinese language support added as a configuration setting.

• Front Panel Display changes:

• Speed display: Configurable filter added to the displayed speed value to reduce displayed speed

variations. The precision of the speed value on the front panel provides one decimal precision

when below 100 rpm.

• Improved front panel performance, providing faster response to a key press.

o Trip button (front panel): Toggles display between the Trip Log and the Trip Latch.

o Alarm button (front panel): Toggles display between the Alarm Log and the Alarm Latch.

o Added Shared Reset, Shared Start and Shared Speed Fail Override display screens

o Rearranged Trip Latch inputs to display more practical faults first (e.g. overspeed).

o Auto Sequence Test: Displayed test result is for the entire sequence, not just the local

module

• Modbus changes:

o The outputs of all analog logic blocks have been included as Modbus analog/register reads.

o Changed the address numbering (Boolean and register) to be consecutive, removing huge

gaps in numbering.

o Added Spare Boolean read registers to prevent errors experienced by devices that queried in

increments of 16.

o Added Scaled analog reads for speed and acceleration to accommodate values exceeding

the 16-bit limits.
