Page 8: General Safety Instructions
The analyzer logic unit/control system is a final controlling element combine to form a safety-instrumented system, which executes a safety function. Note This document deals with the CALOMAT 6 exclusively as part of a safety function. SIL Safety Manual CALOMAT 6 Gas Analyzers A5E00729184-02, 07/2010... - Page 9 Function The measuring principle is based on the different thermal conductivity of gases. The CALOMAT 6 operates with a micro-mechanically manufactured Si chip whose measuring diaphragm contains thin-film resistors. The resistors are regulated at a constant temperature. A current is required to achieve this, and its magnitude assumes a particular value depending on the thermal conductivity of the sample gas.

Page 11: Device-Specific Safety Instructions
The CALOMAT 6 is usable in safety applications to monitor limits. Safety function The CALOMAT 6 is mainly used for user defined threshold monitoring. Only the analog output 4.20 mA (NAMUR) was calculated as safety function. The danger- ous failure is a deviation of the output current of ±5% full span. -

Checking the safety function after installation After installation of the CALOMAT 6 a safety function test has to be carried out (see chapter 4 “Maintenance“ and 5 “Operation“ of the instruction manual CALOMAT 6E/F). -

Maintenance / Checking Checking function We recommend that the functioning of the CALOMAT 6 is checked at regular intervals of one year. Check at least the following: Test the basic functionality of the CALOMAT 6 as described in the Instruction Manual /1/. - Page 14 Generate or simulate an alarm condition to force the Gas Analyzer CALOMAT 6 to go to the high alarm current output and verify that the analog current reaches that value. Generate or simulate an alarm condition to force the Gas Analyzer CALOMAT 6 to go to the low alarm current output and verify that the analog current reaches that value.

(see chapter Appendix). These values apply under the following conditions: The CALOMAT 6 is only used in safety-related systems with a low demand mode for the safety function. The safety-related parameters/settings (see “Settings” section) have been entered by local operation and checked before commencing safety- instrumented operation. -
