1 General Informations1.1 System ApplicationsProtection of rotating machinery such as turbines, expanders, compressors and motors with safety requirements SIL3/IEC61508 and/or API 670 versus Overspeed and other Critical Conditions. Trip is released by shut down of the Trip Circuits (Trip-Lines) for the 2oo3 Solenoid Valve Block if: 2oo3 monitors detect Overspeed condition 2oo3 sensor signals are detected as faulty by monitors 2oo3 monitors detect External Trip-Condition

1.2 Key Features of System E16x346Trip Release Function is SIL3/IEC61508 compliant as stand alone unit (without external testing by DCS or by operator). Total Response Time to Trip Condition : < 15 milliseconds Maximum Safety at Maximum Availability by : TMR (Triple Modular Redundancy) with three monitors E1667. Triple speed measurement and evaluation by each monitor . Variable overspeed setpoint depending on acceleration. Monitoring versus lowspeed as protection versus incorrect mounting of speed sensors. Permanent monitoring of speed sensors. Evaluation of external Trip-Condition signals by voters in each monitor. Response to signals selectable for each voter individually (1oo2, 2oo3, low/high= trip, response time). Permanent monitoring of monitors by testgenerator with cyclic full automatic tests or externally triggered tests.. Permanent monitoring of 2oo3 Solenoid Valve Block by testgenerator with cyclic full automatic or externally triggered tests. Each Trip Line (trip circuit) in 2oo3 technique. Trip Lines I, II, III, IV formed by safety relays with force guided contact sets. Trip-Line-Monitoring with Trip-Lock Function (selectable): The outputs of the Trip Lines to the 2oo3 Solenoid Valve Block are permanently monitored. If the Trip-Lock Function is engaged, a trip condition is detected and locked if 2oo3 trip lines are in trip condition. Remote test of solenoid valve block by test signals from DCS possible. Display in each module for measured values and diagnostics. Alarm outputs via opto relays to DCS. Free extra setpoint from each monitor. Up to 6 speed setpoints with 2oo3 logic outputs (if voters are not required). Sensor signal repeater outputs, free floating and push/pull. Parameters may be set by front keys or by RS232-Interface or by Profibus-Interface.
