  • Page 63: Overspeed And Over-Acceleration Detection Logic

    Each ProTech-GII includes overspeed and over-acceleration functionality and can be configured to meet specific application overspeed and over-acceleration requirements. The ProTech-GII senses speed and then compares the sensed or voted speed to its programmed overspeed trip setpoint to detect an overspeed condition and generate a trip command. Woodward...

    Note: If a speed probe is not connected to a ProTech-GII module the “Probe type” setting must be set to “Not Used”. If the unit is configured for only two probes (or just one probe), there will be a configuration mismatch and associated alarm. This alarm can be disabled in the Configuration Management Menu. Woodward...
  • Page 65 The configuration/use of the Acceleration Redundancy Manager is not required. If the ProTech-GII’s acceleration redundancy manager is not configured for use, then each module simply uses its local speed sensor signal, and compares its calculated acceleration rate to the modules’ over-acceleration setpoint to determine an over-acceleration event.
