1. Introduction
1.1. This “Appendix Exd.ATEX” applies to transmitters of types APC-2000ALW/XX, APR-2000ALW/XX,
APR-2200ALW/XX, APR-2000GALW/XX and APR-2000YALW/XX in Exd versions only, marked on the
rating plate as shown in p.3 and denoted Exd in the Product Certificate.
1.2. The appendix contains supplementary information relating to the Exd (flame-proof) versions compatible
with ATEX directive of mentioned transmitters.
During installation and use of Exd transmitters, reference should be made to DTR.APC.APR.ALW.03(ENG)
in conjunction with “Appendix Exd.ATEX”.
2. Use of APC…, APR… transmitters in dangers zones
2.1. The transmitters are produced in accordance with the requirements of the following standards:
EN 60079-0:2012+A11:2013, EN 60079-1:2014, EN 60079-11:2012, EN 60079-26:2015, EN 60079-31:2014.
2.2. The transmitters may operate in areas where there is a risk of explosion, in accordance with the rating of
the explosion protection design:
Depending on type and device version the following markings are used:
2.2.1. Category 1/2G and 1/2D: (Not applicable to APR-2000GALW / XX)
I M2 Ex db ia I Mb (version with enclosure 1.4401(316))
II 1/2G Ex ia/db IIC T6/T5 Ga/Gb
II 1/2D Ex ia/t IIIC T85ºC/T100ºC Da/Db
KDB 08 ATEX 224X
marking T6 and T85°C applies to range -40ºC <Ta ≤ 45ºC
marking T5 and T100°C applies to range -40ºC <Ta ≤ 75ºC
2.2.2. Category 2G, 2D and M2:
I M2 Ex db ia I Mb (version with enclosure 1.4401(316))
II 2 G Ex ia/db IIC T6/T5 Gb
II 2 D Ex ia/t IIIC T85ºC/T100ºC
Db
KDB 08 ATEX 224X
marking T6 and T85°C applies to range -40ºC <Ta ≤ 45ºC
marking T5 and T100°C applies to range -40ºC <Ta ≤ 75ºC
2.3. Transmitter category and hazard areas.
The category 1/2G (1/2D) means that the transmitter may be installed within a type 1 (21) or 2 (22). hazard
zones. The APC…, APR… process connections may connect to a 0 (20) zone type (see the fig. 1a below
for an example). The category 2G (2D) , means that the transmitter together with process connections may
be installed within a type 1 (21) or 2 (22) hazard zones (see the fig. 1b below for an example).
Transmitters marked I M2 turn off if there is risk of an explosive atmosphere.
