SAFETY MANUAL Pulse Generator 8444, Triplicated, 24VDC Zone Interface 8448 Triplicated, 24VDC Valve Monitor 8449, Triplicated, 24VDC TÜV Certified Configuration Not safety related but interference free Internal 2oo3 (2oo3 implemented in a single module) Internal 2oo3 (2oo3 implemented in a single module) Conditions Certified as non-interfering and can be used for nonsafety-critical devices. Outputs: Normally energized (de-energize to trip): certified SIL 3 or AK6. Normally de-energized (energize to trip): certified only for applications that fulfil the requirements under section 3.2.4. May be used in single module or master/slave configurations. Inputs: Normally de-energized (energize to trip): only for applications that fulfil the requirements under section 3.2.4, and only for “trip amplifier” (like gas inputs) or quasi digital inputs (like fire loops). Normally energized (de-energize to trip): certified only if the inputs are dynamically transitioned at a period not greater than the second fault occurrence time. Analog measurements: certified only if the input is dynamically exercised over its full range within a period shorter than the second fault occurrence time 3 . Non-interfering for non-safety-critical devices Outputs: Normally energized (de-energize to trip): certified SIL 3 or AK6. Normally de-energized (energize to trip): certified only for applications that fulfil the requirements under section 3.2.4. Safety critical valve may only be tested towards the safe position. May be used in single module or master/slave configurations. Inputs: Certified as non-interfering and can be used for nonsafety-critical devices. Table 4 - Multi-purpose Modules, High Density I/O 3 The analog input must be exercised over it’s full range (i.e. 0 to 4095) over a period of time related to the safety accuracy specification of the module and the discrepancy detection time configured for the system. For typical systems, the discrepancy detection time is 200 seconds. Doc No P8094 Page 40 of 67 Issue 14 September 2003
