Installation and operating instructions

Transmitters
The transmitters are factory-set to the specified measuring range, and are adjusted as standard for
vertical installation. Subsequent adjustment of the units is unnecessary. If the mounting position is
subsequently changed, correction of the zero point is necessary with low pressure measuring ranges
< 1.6 bar (< 23.2 psi). The zero correction does not change the span (sensitivity). Electrical installation,
commissioning and zero correction must only be carried out by trained personnel with observation of the
data sheet (see zero correction).
Compensation of the internal atmospheric pressure of the pressure transmitters for overpressure ranges
is carried out in the plug versions via the screwed gland (IP65), in the field housing by an integral sintered
filter (IP65) or vented cable (IP67), and in the version with cable outlet only via a vented cable (IP67).
Absolute pressure ranges do not require compensation with respect to atmospheric pressure. These
degrees of protection are only achieved if the unit is installed correctly, if the screwed glands are securely
tightened, and if the cable diameters agree with the nominal diameters of the gaskets in the housing. The
integral EMC measures are only effective if the earth connection is made correctly.
The CE marking of the units certifies compliance with the guidelines of the European Council
(89/336/EC), the EMC law (13.11.1992), as well as the applicable generic standards, product standards
and basic standards. Interference-free operation in systems and plants is achieved if the specifications for
shielding,earthing, cable routing and electrical isolation are observed during installation and assembly.
Electrical equipment in hazardous areas must only be installed and operated by trained personnel.
Modifications to units and connections result in cancellation of the explosion protection. With intrinsically-
safe circuits, make sure that equipotential bonding exists throughout the complete cabling inside and
outside of the hazardous area. The limits specified in the ATEX approval must be observed.
Remote seals
Process installation and commissioning must only be carried out by trained personnel. The supplied
protective cap in front of the remote seal foil or plastic sleeve should only be removed immediately prior to
installation in order to prevent contamination or damage. In designs with thermal decouplers, make sure
that these are not included in the insulation.
NOTE
The corresponding standard pressure rating must be observed for all process connections.
In particular with clamp-on connections, operation outside the permissible pressure rating is
only possible when using appropriate clamps. The information in DIN 32 676 concerning
temperature resistance must be observed.
