11.1
sampling pipe
If the sampling pipe is being used in extremely corrosive environments, provide for sufficiently resistant tube materials. Please
contact the manufacturer of the ASD 532 for the material specifications.
Danger
Tube materials other than those listed in Sec. 5.3 may be used only after consulting with the manufacturer of the
ASD 532 and with his written consent.
Only use tubes (material, supplier, dimensions) which have been tested and approved by the manufacturer of the
ASD 532 (see also Sec. 5.3).
11.2
Use under extreme conditions
Applications with extremely high levels of dust and/or dirt, extreme temperature ranges and/or atmospheric humidity outside
the specified limit values require the use of accessory parts as instructed by the manufacturer, e.g.:
•
Filter-box/filter unit;
•
Dirt trap box;
•
Dust retaining box;
•
Water retaining box;
•
Manual ball valve for sporadic cleaning of the sampling pipe using compressed air;
•
Automatic blow-out device;
•
Insulation of the sampling pipe;
•
Use of cooling sections in the sampling pipe
Notice
Operation and application under extreme conditions may be implemented only after consulting with the manufac-
turer and under his supervision.
The use of the aforementioned accessory parts is subject to a sampling pipe calculation using “ASD PipeFlow”
(exceptions, see Sec. 4.3.1).
The initial reset during commissioning must be carried out with the accessory parts required for operation under
extreme conditions.
If an additional unit is retrofitted to an ASD 532 already installed, a new initial reset must be carried out.
11.3
Use of detector boxes
Additional detector boxes (e.g. REK 511) may have to be used in the sampling pipe to create detection areas (e.g. horizontal
localisation). The applicable country-specific guidelines must be observed (e.g. DIN VDE 0833-2 in Germany, Cantonal Fire
Insurance Union in Switzerland). For more information on the REK 511 detector box, please refer to the separate data sheet
(T 135 422).
Warning
The REK 511 detector box cannot be operated from the ASD 532. The REK 511 detector box has to be con-
nected directly from the FACP using an appropriate addressing module.
When using detector boxes, it may be necessary to carry out a sampling pipe calculation using “ASD PipeFlow”
(see Sec. 4.3.2).
