In the case of significant increase in medium temperature measurement of Tp must be executed again and
again must be specified the temperature class for the gas or the maximum surface temperature
combustible dust.
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 cable intakes 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.
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.
