8. Special Versions
8.1 DS 5 + DS 10 -GL-Version
These sounders have been designed and certifi ed in accordance with the Guideline of German Lloyd. Special demands are
made on the stability when exposed to environment al infl uences and on electromagnetic compatibility (EMC).
8.2 9.2 Special versions for explosion hazard zones 2 and 22: DS 5 -3G/ 3D and DS 10 -3G/ 3D
These sounders are suitable for use in an explosion-hazard environment in zones 2 acc. to EN 60079-10-1 and 22 acc. to
EN 60079-10-2. The sounders can be used for gases of the temperature classes T1, T2, T3 and T4 as well as for environments
with non-conductive dusts.
The surface temperature of the housing does not exceed +135°C.
Standard conformity:
Identifi cation marking:
PDG 03.0001 X
Installation requirements:
The sounders are to be installed in conformity with current editions of the appropriate parts of DIN EN 60079 or in accordance
with equivalent IEC specifi cations.
EN 60079-10-1
Explosive atmospheres - Part 10-1: Classifi cation of areas - Explosive gas atmospheres
EN 60079-10-2
Explosive atmospheres - Part 10-2: Classifi cation of areas - Combustible dust atmospheres
EN 60079-14
Explosive atmospheres - Part 14: Electrical installations design, selection and erection
Applicable national constructor provisions are to be observed in the case of all work on the sounder.
In the case of work in explosion-hazard areas, the safety of persons and equipment depends upon adherence to all of the
relevant safety regulations. The following is to be observed:
- Equipment Safety Act
- National safety regulations
- National accident prevention regulations
- National construction and erection regulations
- Generally accepted rules of technology
- Characteristic values of the sounder according to the rating plate and the operating instructions
Special conditions X
The sounders are designed to be used in stationary installation. When using the original cable gland a strain relief for the
connecting cable has to be ensured. The cable gland is restricted for applications with a low degree of mechanical hazard
according to EN60079-0. If a protected installation is not possible Ex-e cable glands without restriction combined with a con-
nection thread gasket have to be used.
Minimum requirement : M20x1,5, IP66/67, II3G Ex e IIC Gc / II3D Ex tc IIIB Dc, Tamb. -25°C .. +70°C.
Further Notes:
The type of protection IP 66/67 must be established after installation by means of proper and correct closing of the casing
and the use of matching cables and screwed cable glands. The sealing range of the screwed cable gland is to be adhered
to. (Original cable gland: 7 - 13mm.)
During installation the seal of the housing is to be checked for damage and function. Damage can cancel out the explosion
protection.
The housing screws (Torx-T20) are to be tightened with a torque of
approximately 2 - 2,5 Nm in at least two passages crosswise.
Do not cover the opening of the bell mouth during opera-
tion otherwise too high surface temperatures may occur.
The opening of the
wards after installation. Replacement of the device after
ten years is recommended.
Additional safety notes:
Do not open when energised!
Do not open when there is an explosive atmosphere!
9. Maintenance Instructions
The sounder does not require any special maintenance. External cleaning should be done moist with a mild soap solution with-
out the use of solvents. The sounder may only be operated in the undamaged state within the specifi ed rating. Conversions,
alterations, improper and inadmissible use as well as the non-observance of the notes in these operating instructions shall
render the warranty null and void. Components may be replaced only by original spare parts. As a matter of principle, repairs
are to be carried out in the manufacturing works.
