Page 23: Mounting Location Considerations
II (per IEC 60664-1) Power Supply Requirements Each ProTech-GII system consists of three separate internal modules (A, B, C), and each of these three modules accept two input power sources. Depending on the ProTech-GII model purchased, the internal modules will accept either two high voltage (HV) input power sources or one HV input power source and one low voltage (LV) input power source. - Page 24 Input #2: Low Voltage Power Supply (18–32 Vdc) @ 90 W (30 W per module) o Nominally 24 Vdc Each ProTech-GII module will function normally with power sourced to both or either power supply input independently, however Woodward recommends that both input power sources be used to improve system availability. Please refer to Table 1-1 for available ProTech-GII models.

Do not connect a speed probe to more than one input. This will compromise the ability of the ProTech-GII to sense open wire (passive mode only) and interfere with the minimum amplitude sensitivity and accuracy.

No custom application program is required to be loaded for this functionality to operate normally. The ProTech-GII senses speed and then compares the sensed speed to its programmed overspeed trip setpoint to detect an overspeed condition and generate a trip command. -
Page 56: Start Logic
Peak speed and peak acceleration are tracked and logged for every overspeed and over-acceleration occurrence, the last 20 occurrences logged and can be viewed from a front panel or loaded to a computer via the ProTech-GII Programming and Configuration Tool (PCT). -

Page 58: Test Routines
ProTech-GII Overspeed Protection Device Manual 26545 Test Routines Each ProTech-GII module provides a variety of test routines to support common test requirements. In general, a test may not be started if any other module is tripped or in test or if the current module is tripped or in test. - Page 59 This test can only be performed from the front panel of the ProTech-GII. When the test is initiated, the frequency generator automatically starts at 100 rpm below the overspeed setpoint.

Page 60: Alarm And Trip Latches
In the “Voted Trip Relay” version of the ProTech-GII, at least two modules would have to be in the tripped state for the voter relay to go to its tripped state. - Page 61 Manual 26545 ProTech-GII Overspeed Protection Device A "trip" of the module refers to the action of the ProTech-GII module changing the state of its Trip output. When any of the Trip Latch inputs becomes true, the output of the trip latch is set TRUE. The red TRIPPED light is illuminated on the front panel.

Page 62: System Logs
Each module in the ProTech-GII logs (saves to memory) all trips, alarms, and overspeed or over-acceleration events. Peak speed and peak acceleration are also logged.

10 seconds or the sequence must be re-initiated. The ProTech-GII is designed to allow only one module to be tested at a time. Thus a module will only accept an Initiate Test command and perform the requested test if all three modules are healthy, not tripped, and not in a test mode. -
Page 67: Protech-Gii Parameter Addresses
Since Modbus can only handle integers, values that require a decimal point in the Modbus Master Device are multiplied by a scaling constant before being sent by ProTech-GII. See the Modbus list for the scaling used on each analog parameter. Boolean Writes (Code 05) Boolean Write registers are used by an external master device (plant DCS, etc.) -
