Safety Manual
4.5
Installation in hazardous areas
The IECEx Installation drawing, ATEX Installation drawing and FM
Installation drawing shall be followed if the products are installed in or
connected to hazardous areas.
4.6. Installation in SIl 3 applications
The independence of the safety functions enables the use of the two
channels in a 9106 HART ® Transparent Repeater device, in a SIL 3
safety function when both inputs are connected in series.
The safety PLC or equivalent connected to the output shall be able
to detect and handle the fault indications from both analogue outputs
of the 9106 Repeater by having NAMUR NE43-compliant input circuits
and must be able to compare the two channels.
5. functional specification of the safety functions
Galvanic isolation of an active or passive 4...20 mA current signal from hazardous
areas to an active or passive 4..20 mA output signal in non-classified area or
zone2 / Div. 2, within the specified accuracy.
6. functional specification of the non-safety functions
The status relay (terminal 33 and 34), error signal on power rail (terminal 91) and
LED outputs are not suitable for use in any Safety Instrumented Function. The
display value and any possible parameterisation by the 4501 add on module does
not affect the safety function of the 9106.
Also the HART ® transparency of the module is not a safety function.
