Special Conditions for Safe Use
This Equipment is Suitable for use in Class I, Division 2, Groups A, B, C, D or
Non Hazardous Locations Only.
This equipment is suitable for use in European Zone 2, Group IIC environments
or Non Hazardous Locations Only.
Wiring must be in accordance with North American Class I, Division 2, or
European Zone 2, Category 3 wiring methods as applicable, and in accordance
with the authority having jurisdiction.
A fixed wiring installation is required and a switch or circuit breaker shall be
included in the building installation that is in close proximity to the equipment and
within easy reach of the operator and that is clearly marked as the disconnecting
device for the equipment. The switch or circuit breaker shall not interrupt the
protective earth conductor.
Protective Earth Grounding is required by the input PE terminal.
Field wiring must be rated at least 85 °C for operating ambient temperatures
expected to exceed 50 °C.
For European ATEX compliance on panel mount models, this equipment must be
installed in an area providing adequate protection against the entry of dust or
water. A minimum ingress protection rating of IP54 is required for the enclosure.
Personnel must discharge their electrostatic build up to the cabinet ground point
or use an ESD strap prior to touching the ProTech
®
interior surfaces if the
engine/turbine is operational. The unit is designed to have one of three modules
be removed during operation; however ESD to the remaining operational
modules may cause signal deviations. Signal deviations due to direct ESD may
be large enough to result in the operational module to trip, shutting down the
engine since two modules are in a tripped mode. Signal deviations were noted
when ESD testing was done to the Speed pins, the IRIG-B pins, Service Port
pins, and RS-232/RS-485 Modbus communications port pins.

Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others.
To protect these components from static damage, you must take special
precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1. Before doing maintenance on the electronic control, discharge the static
electricity on your body to ground by touching and holding a grounded metal
object (pipes, cabinets, equipment, etc.).
2. Avoid the build-up of static electricity on your body by not wearing clothing
made of synthetic materials. Wear cotton or cotton-blend materials as much
as possible because these do not store static electric charges as much as
synthetics.
3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam
cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or
folders, plastic bottles, and plastic ash trays) away from the control, the
modules, and the work area as much as possible.
4. Do not remove the printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the control
cabinet, follow these precautions:
Do not touch any part of the PCB except the edges.
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual
82715, Guide for Handling and Protection of Electronic Controls,
Printed Circuit Boards, and Modules.

General Information
Description
The ProTech-GII is a device designed to safely shutdown steam, gas and hydro
turbines, as well as motors, compressors, reciprocating engines and other
equipment, upon sensing an overspeed or over-acceleration event.
The ProTech-GII consists of three independent modules whose trip outputs are
either independent or voted in a 2-out-of-3 configuration. The ProTech-GII
includes Overspeed/Overacceleration, Alarm, and Trip log functions with time-
stamping. Indication that a test was active at the time of the event is provided on
all logs and first-out indications are provided for Trip logs.
The ProTech-GII provides various pre-defined test features including automated
periodic tests.
There are several ways to interface with the ProTech-GII. The front panel allows
the user to view current values, and perform configuration and test functions. All
of the features and most of the information available from the front panel are also
accessible via the Modbus
®
interface. Finally, the Programming and
Configuration Tool (PCT) is software that is run on a PC to download log files
and manage settings files.

Applications
The ProTech-GII is designed to be applied as an overspeed device for any size
steam, gas, or hydro turbine, reciprocating engine, or plant process equipment.
The device's fast (12 millisecond) response time, 0.5 to 32 000 rpm speed range,
and integrated overspeed and acceleration detection/protection functionality,
make it ideal for application on critical low-speed or high-speed rotating motors,
compressors, turbines or engines. This device accepts one speed (MPU or
PROX) input per module (3 total). In addition to the trip relay outputs, each
ProTech-GII module provides 1 relay output that is dedicated to an alarm
function (3 total) and 1 analog speed output (3 total).
The ProTech-GII utilizes a triple modular redundant architecture and 2-out-of-3
voting logic to accurately determine unsafe conditions and ensure that no single-
point failure will affect system reliability or availability. With this design, failures in
overspeed system components (switches, transducers, modules) are detected,
annunciated, and allowed to be repaired or replaced while the monitored system
continues to operate on-line. The ProTech-GII is designed for critical applications
where both personnel safety and unit availability (operation run time) is a concern
or necessity.
The ProTech-GII is certified as an IEC61508 SIL-3 (Safety Integrity Level 3)
safety device and can be applied as a stand-alone IEC61508-based device or
within an IEC61511-based plant safety system.

to a specific application.
Electrical ratings, wiring requirements, and options are provided to allow a
customer to fully install the ProTech-GII into a new or existing application.
Unpacking
Before opening the shipping packaging, inspect the shipping container for
damage and document any damage.
Be careful when opening & removing the shipping container. You may retain the
original shipping container for unit storage or return shipping for suggested
refurbishment. (See Asset Management chapter for storage details.)
Be careful when unpacking the ProTech-GII system from the shipping container.
The precautions called out in the Electrostatic Discharge Awareness section
should be followed during unpacking, handling, installation and operation during
maintenance.
Once removed from the shipping packaging, check the device for signs of
damage such as a bent or dented case and loose or broken parts. If damage is
found, notify the shipper immediately.
System Installation Procedure
1. Read and understand this manual completely before proceeding.
2. Create a site specific wiring diagram by referencing included wiring
diagrams & constraints then perform mechanical and electrical installation
following this chapter’s instructions.
3. Visual inspection
a. Verify that all mounting hardware is tightened and that no wires are
pinched.
b. Verify that no wiring insulation is nicked or abraded.
c. Verify that all terminal blocks are installed and terminal screws are
tight. (Follow control wiring instructions for all terminal blocks.)
d. If used, verify that speed sensors have been correctly installed, and
have the correct clearance from the speed gear (adjust if necessary).
See manual 82510, Magnetic Pickups and Proximity Switches for
Electronic Governors.
4. Apply power to each module (one at a time), and verify that each module
boots up and its front panel screen displays turbine or equipment speed.
5. If no special programming is used skip to step 11.
6. From the respective module’s front panel copy downloaded program to
other unit modules.

7. From each module’s front panel verify that the correct program has been
installed in each module by comparing unit CRC codes.
8. From each module’s front panel, enter the configuration mode and verify
that each of the overspeed and over-acceleration settings are correct.
9. Enter the configuration mode and configure all settings to the specific
application’s requirements.
10. Perform a full system checkout by verifying all system trips, alarms, and test
routines function correctly before starting the machinery/system.
11. When ready, start the turbine or equipment/machinery following the
equipment manufacturer’s recommended starting procedure.
Enclosures
Module identification is always from left to right, with module A on the
left, module B in the center, and module C on the right. This applies to
either the bulkhead-mount versions with the front cover open, or the
panel-mount versions with the back cover removed.
Depending on the model purchased, the ProTech-GII has either a bulkhead-
mounted or a panel-mounted enclosure package.
The bulkhead-mounted enclosure models are designed to be mounted on a wall
or skid next to the turbine or equipment and are rated for IP56-based
environments. With these models, field wiring access is through gland plates
located on the bottom of the enclosure. Figures 2-1, 2-2, and 2-3 display the
bulkhead mounted ProTech-GII model’s physical layout and mounting pattern.
The ProTech-GII panel-mounted enclosure models are designed for installation
within a control room panel or cabinet, and by itself, it cannot be bulkhead
mounted. Once installed within an IP56 rated panel or cabinet, the ProTech-GII
panel-mounted models are rated for IP56-based environments. A gasket is
attached to the rear side of the package’s bezel to properly seal the ProTech-GII
control’s face-plate and around the mounting studs to a panel. With these
models, field wiring access is located on the ProTech-GII control’s back side, and
a back cover is included to protect wiring terminals after installation. Figures 2-4
and 2-5 display the Panel-Mount ProTech-GII model’s layout and mounting
pattern.
