FOR YOUR SAFETY
Marking of device components
Control unit Z200EXG-y1********************* (y= 1, 2)
●
ATEX
II 2G Ex db IIC T6 Gb
●
IECEx
Ex db IIC T6 Gb
●
Special conditions:
Equipment used to the cable inlets and plugs for unused threads for cable inlets must be
certified according to IEC 60079-0 and IEC 60079-1.
It is not permitted to repair flameproof joints in the enclosure.
Analyzer unit Z200EXG-y2********************* (y= 1, 2)
●
ATEX
II 2G Ex db IIC T3 Gb
●
IECEx
Ex db IIC T3 Gb
●
Special conditions for safe use:
– The specification of temperature class T3 applies to an ambient temperature range of
-20 °C to +55 °C.
– The heater voltage of the measuring probe must be switched off by a monitoring
device independent of the control and certified for this use when a limit temperature
of 890 °C for an ambient temperature of up to 40 °C and a limit temperature of
845 °C for an ambient temperature of up to 55 °C is reached.
– The warning to open the enclosure and the manufacturer's instructions must be
strictly followed.
– Only use the oxygen analyzer unit with associated protective pipe with flue gas feed in
flue gases, when the composition is not critical concerning the corrosion effect on the
materials used. If this cannot be ensured, regular recurring checks must be carried
out at sufficiently short intervals.
– The flue gas temperature must not exceed 500 °C on the measuring probe. Higher
process temperatures are possible when a suitable flue gas line with flue gas cooling
ensures that the flue gas does not exceed the limit value of 500 °C under all process
conditions when it reaches the analyzer unit.
Pneumatic unit Z200EXG
