8237-1604 integrated overspeed protection Keys Per Module

8237-1367

Programming

• The ProTechTPS functions as a safety PLC, as it accepts 10 discrete or analog inputs per module
• (30 total), and allows users to create custom safety/protection programs to safely protect site personnel
• and equipment. Programmers are able to utilize typical logic and testing sequence routines to create their application-specific safety logic and tests.

On-Line Testing

• Each ProTechTPS module can be tested manually from the module’s front panel, Modbus
• communications port, or automatically via its auto-test routine function. The ProTechTPS allows
• users to configure overspeed or custom-programmed tests to be performed manually or automatically
• on a periodic basis. With these test routines, each module (A, B, C) is tested one at a time, and
• either a successful test result is logged or, upon sensing a fault, the routine is halted and the sensed fault indicated/alarmed.

On-Line Repair

• The ProTechTPS’s triple modular design allows users to easily replace one of its modules (A, B, C)
• while the monitored equipment/turbine is on-line and operating normally. Ease of replacement is
• enhanced by the unit’s backplane plug-and-operate structure, and its module-to-module learning function.

Trip, Alarm, & Overspeed Logs

• The ProTechTPS log function logs (saves to memory) all trips, alarms, trip valve response times, and
• overspeed events. The trip log function uses a scrolling buffer and records the last 50 sensed trip
• or alarm events and the last 20 overspeed events to memory, with associated times. Each log file can
• be viewed from the unit’s front panel, or downloaded to a computer via the ProTechTPS service
• tool program. Each module utilizes nonvolatile memory to ensure that all logged events are saved, even on loss of power.
