Key Features:

High Resolution Displays: Each module includes a high resolution 4.2” (107 mm) color display and keypad to allow users to locally monitor configuration settings, statuses, system inputs and outputs, and alarm, trip, and overspeed logs.

Automatic Overspeed Test Routine: Optionally, the ProTechTPS can be configured to routinely perform and overspeed test each module/trip solenoid, then log and report the test results. With this test routine, each module is sequenced through its test sequence using an internal frequency generator to simulate an overspeed condition.

Automatic Test Routines: Optionally, the ProTechTPS can be configured to routinely perform custom tests of each module/trip solenoid, then log and report the test results. With this test routine, each module is sequenced through a programmed test sequence to simulate, test, and log the results of each safety event condition.

Acceleration/Deceleration Detection: Optionally, the ProTechTPS can be configured to protect a turbine from high acceleration/deceleration events. The derivative of the speed signal is used to detect turbine acceleration/deceleration and issue an associated trip command.

MPU Detection: Each module’s speed sensor input uses special MPU open-wire detection circuitry to validate that the MPU is properly connected before turbine operation, and special loss-of-speed detection logic to validate MPU functionality during turbine operation.

Sulfur Contamination Resistant: Utilizes special conformal coating material that has demonstrated excellent long-term protection against H₂S and SO₂ gases at levels classified in international standard IEC 721-3-3 1994 – environment Class 3C2.
