I. APPENDIX Exd
DPT –2000ALW TEMPERATURE TRANSMITTER
Exd VERSION
1. Introduction
1.1. This “Appendix Exd.01” applies to transmitters of type DPT-2000ALW in Exd versions only,
marked on the rating plate as shown in 3 and denoted Exd in the Product Certificate.
1.2. The appendix contains supplementary information relating to the Exd (flame-proof) versions of mentioned
transmitters.
During installation and use of Exd transmitters, reference should be made to
DTR.DPT.ALW.03
in conjunction with “Appendix Exd.01”.
2. Use of DPT
–2000ALW transmitters in danger zones
2.1. The transmitters are produced in accordance with the requirements of the following standards:
EN 60079-0:2012, EN 60079-1:2007, EN 60079-11:2012, EN 60079-26:2007, EN 60079-31:2009.
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:
I M2 Ex d ia I Mb (steel enclosure only)
II 1/2G Ex ia/d IIC T* Ga/Gb
II 1/2D Ex ia/t IIIC T* Da/Db
-40 ° C <= Ta <= +45 ° C/+75 ° C
KDB 13 ATEX
T* - temperature class for transmitter (for gases) or a maximum surface temperature (for dust) derived in
clause 5.3 and 5.4.
2.3 Transmitter category and hazard areas.
The category 1/2G, contained within the rating, means that the transmitter may be installed within a type 1 or 2
hazard zone. The process connections may connect to a 0 zone type (see the diagram below for an example).
3. Identifying marks .
Flame-proof transmitters must have a rating plate containing the information specified in paragraph 4.1 of
DTR.DPT.ALW.03 and also at least the following:
- CE mark and number of notified unit: mark,
- Designation of explosion protection design, certificate number,
- Power supply,
- Process connection,
- Year of manufacture,
- Temperature use range ,
4. User information.
Together with the ordered transmitters, the user will receive:
a) Product Certificate
b) Declaration of conformity
c) Copy of certificate – on request
d) User’s Manual numbered: DTR.DPT.ALW.03 with Appendix Exd0.1.
User can find them b), c), d) at www.delta-controls.com
5. Power supply and exploitation of transmitters
5.1. The transmitter connecting should be made after introduction with present instruction content.
Electrically transmitter should be connected according to scheme at p.6 Appendix Exd.01. Transmitter
electrical installation should be realised with engineering standard requirements.Electrical connections
of transmitters in danger zone should be made by people who have indispensable knowledge and
experience in this branch.
5.2. Earth clamps must be used with earth transmitters. In the event that transmitters come in contact with
structural metal parts or pipes which are connected to the equipotential bonding system, transmitters do
not require to be earthed.
T ransmitters should be supplied from DC electrical source with voltage
max.45V from transformer feeders or other devices which have at least a strengthened isolation among
