These operating instructions refer to installation, commissioning,
servicing and adjustment. Statutory regulations, valid standards,
additional technical details in the relevant data sheet, details of the
type plate and any additional certificates are to be observed along
with these operating instructions.
Installation, operation and maintenance of the instrument may be
executed by authorized personnel, only, using suitable
equipment.
Warning: If the instrument is used incorrectly it is possible that
serious injuries or damage can occur!
Prior to the disassembly of the pressure transmitter the impulse
ducts between the measuring transmitter and the process have to
be locked and relieved from pressure.
The standard nominal pressure rating and the permissible
operating temperature of the gasket should be observed for all
process connections. Operation outside the allowed nominal
pressure rating, especially with clamp connections, is only
possible with suitable clamps. In this case, note DIN 32676 for
stipulations on heat resistance.
Pressure transmitters that are mechanically defective can cause
injuries or give rise to process faults. Suitable precautions should
be taken to avoid this.
The CE marking on the instruments certifies compliance with valid
EU directives for bringing products to market within the European
Union. The following directives are met:
EMC directives EMC 2004/108/EG
Pressure Equipment Directive PED 97/23/EG
Ex directive ATEX 94/9/EG
Lower Voltage Directive LVD 2006/95/EG
Electrical equipment in hazardous areas should only be installed
and commissioned by competent personnel. Modifications to
devices and connections destroy the operating safety, the ex
proofing and the guarantee. The limit values detailed in the
certificate of conformity are to be observed

.
Before mounting the instrument ensure that pressure range,
overpressure resistance, media compatibility, thermostability and
pressure port are suitable for the process at hand.
Conduct process installation before electrical installation.
Measuring instruments that should not have any oil or grease
residues in the pressure port are marked „Free of oil and grease“.
Gaskets must be chosen that are suited to the process
connection and resistant to the measured medium.
Excess pressure on the minus side of the measuring system can
damage the instrument.
Check for pressure tightness when commissioning the
transmitter.
Wire up the instrument with power switched off.
The housing in protection class IP67 consists of a two chamber
system in which the measuring cell is aerated directly in relation
to the environment by means of a PTFE filter system.
The mounting position should be taken into consideration when
checking the zero output. Standard transmitters are adjusted at
the factory for vertical mounting. Changes to the mounting
position can cause zero shifts at pressure ranges < 2 bar. These
drifts can be corrected by adjustment on site.
When the instrument is opened any contact with the electrical
connections can affect the signals. This situation can be avoided
by switching off the supply voltage or by disconnecting the signal
circuit.
The types of protection IP67 are only achieved, when the
threaded ring has been screwed tight after electrical
connection/parameterization.
The instrument requires no maintenance.
The instrument can only be protected against electromagnetic
interference (EMC) if the conditions for screening, earthing, wiring
and potential isolation are met during installation.
To avoid soiling and damage remove protective cap or wrapping
in front of the separating diaphragm before mounting.
Do not touch the flush mounted separating diaphragm, as there is
a danger of deformation at measuring ranges to 10 bar / 150 psi.
Instrument zero point and measuring characteristics could also be
affected.
Measuring instrument and diaphragm seal are a closed
system and should not be separated.
Avoid overtightening the process screw joints as this can result in
zero displacements at the pressure transmitter (fixing error).
When using systems with capillary for vacuum measurements
always mount the pressure transmitter underneath the diaphragm
seal. The instruments are set at the factory with pressure
transmitter and diaphragm seal at the same height. Correct any
differences in height between diaphragm seal and pressure
transmitter arising from conditions on site on the pressure
transmitter when placing the instrument into operation (see zero
point correction). When correcting for elevation be aware of the
adjustment limits.
Be sure to install and securely fasten the capillary to avoid
vibrations. Roll up overlengths with a minimum radius of 50 cm.
Shock and changes in temperature can impact on measurements.
Process and ambient temperatures can cause zero
displacements at the pressure transmitter with some system
designs. We can supply you with an error analysis.
Should you need to adjust the zero-point on site, then undo the
front threaded ring to gain access to the controls. You will find
instructions on using the keyboard in your manual. To set the
measuring span, you should apply an accurate reference pressure.
Store and transport pressure transmitters under dry, clean condition
and, where possible, in their original packaging.
Permissible storage temperature: –25°C.....+60°C. Avoid shock
and vibrations.
