Model 9010/9020 SIL

10.3 Special Conditions for the Safe Use of the Gas Warning Unit 9010/9020 in SIL Applications

Safety Relevant Parameters for the Gas Warning Unit 9010/9020

Using Relays

Possible Structures and Acquirable SILs

The following table shows, which structure has to be selected, to fulfill the requirements of a
special SIL.
LDM = Low Demand Mode
HDM = High Demand or Continuous Mode

Using Relays

Depending on the selected configuration the following safety-relevant parameters have to be
considered while implementing the safety loop:

General Conditions for Safe Use

(1) The application advice and the limitations of the manual have to be considered.

(2) For calibration and maintenance, the regional and national regulations have to be

considered.

(3) A defect Gas Warning Unit 9010/9020 has to be repaired within 72 h.

(4) An ambient temperature above 40 °C is to be avoided.

(5) External power supplies must fulfil the requirements of EN 60950 and EN 50178 for SELV,

PELV.

(6) The communication interfaces are not allowed to be used for the transmission of safety

related data.

(7) The 4…20 mA - Output is not allowed to be used for safety function.
