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.DPC.DPR.ALW.03 with Appendix Exd0.2.
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. 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. Earth clamps must be used to 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.
5.2. Transmitters 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 primary and secondary
windings in which don’t appear voltage higher than 250V. The duty of power supply installation with
above mentioned requirements rests on user.
5.3. Transmitters can be use in ambient temperatures (Ta) between - 40°C < Ta ≤ 45°C for T6 class or
between -40°C < Ta

75°C forT5 class.
5.4. Transmitter sensor diaphragm not should be subject on damage during installation and exploitation.
The diaphragm is made from 316ss or Hastelloy thin foil and cannot be subject on medium which can
entail its damage.
5.5. With regard on kind of casing material (light alloy with large aluminium content), the user is obliged to
assure, that possibility of hitting casing does not step out in place of transmitter installation.
5.6. In transmitter casing are two holes to assembly of packing glands from thread M20x1,5 or 1/2 NPT.
5.7. Normally transmitters are delivered without installed glands but with blank plugs (corks) in the second
hole. They are at table 1 and table 2 at list of packing glands and plugs agreeable with production
documentation and accepted by certificate station. Customer should install packing glands according to
tables 1
and plugs according to tables 2 (if plugs aren’t installed) or other accordance with flame-proof
standards.
5.8. It is necessary apply a shield cable or without shield cable with round cross-section in protection from
elastomer, not moisture absorbing, for example: YKSLY 2 * 1, YnTKSYekw 1 * 2 * 1, LIYCY 2 * In case
of need of use cable about different building customer should co-ordinate this with transmitters
manufacturer to choose intakes with cable diameter.
5.9. The general principles of connecting and the exploitation of transmitter in Exd realization should be
compatible with principles and relating standards for Exd casing devices how in p.2.1, in this including
also : EN600079-14, EN60079-17.
5.10. During service must be made a check of the tight fastening of covers and the packing glands and the
fastening of the cable in the glands. The casing and supply line must be inspected for mechanical
damage, and the transmitter rating plate for legibility. Periodic checks should also be made of the
diaphragm, which should not carry signs of damage. During maintenance it is recommended that the
threads of the covers be lubricated with non-acid vaseline.
Blocking cover method before unscrewing and plumbing possibility is shown at fig 20.
Because of the transmitter damage possibility, the ambient temperature should not be allowed
to become higher than 80

C, even when there is no explosion risk.
It is not permitted to repair or otherwise interfere with the transmitter’s electrical circuits in any
way. Damage estimation and repair possibility may be assessed by the manufacturer or another
authorized party only.
In danger zone don’t unscrew transmitter covers and don’t change the display position or its
back lighting.
