1.3 Target group

WARNING! To avoid operator hazards and damages of
the device, the following instructions have to be worked
out by qualified technical personnel.

1.4 Limitation of liability

By non-observance of the operating manual, inappropriate
use, modification or damage, no liability is assumed and
warranty claims will be excluded.

The conformity of the produced end device has to be en­sured by the responsible design engineer or developer.

1.5 Intended use

- The pressure transmitter EP 500 has been designed for
hard conditions especially in shipbuilding and offshore
applications. The EP 500 is intended, depending on the
ordered pressure range, for the pressure measurement
of gauge or absolute pressure. A typical application is
e.g. level measurement via air bubbling. The EP 500 ful­fil the requirements of Germanischer Lloyd (GL) as
standard. The certificate is available for download on
our homepage: http://www.bdsensors.com/proucts/
download/certificates

- It is the operator's responsibility to check and verify the
suitability of the device for the intended application. If
any doubts remain, please contact our sales department
in order to ensure proper usage. BD SENSORS is not
liable for any incorrect selections and their effects!

- Permissible media are gases or liquids, which are com­patible with the media, wetted parts of the device.

- The technical data listed in the current data sheet are
engaging and must be complied with. If the data sheet is
not available, please order or download it from our
homepage: http://www.bdsensors.com/products/down­load/datasheets

WARNING! Danger through improper usage!

3. Mechanical installation

3.1 Mounting and safety instructions

WARNING! Install the device only when depressurized
and currentless!

WARNING! This device may only be installed by
qualified technical personnel who has read and under­stood the operating manual!

!

Handle this high-sensitive electronic precision
measuring device with care, both in packed and
unpacked condition!

!

There are no modifications/changes to be made on the
device.

!

Do not throw the package/device!

!

To avoid damaging the diaphragm, remove packaging
and protective cap directly before starting assembly.
The delivered protective cap has to be stored!

!

Place the protective cap on the pressure port again
immediately after disassembling.

!

Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.

!

Do not use any force when installing the device to
prevent damage of the device and the plant!

!

For the installation following points have to be ob­served:

- By factory, the device has an ingress protection of
IP 00. Therefore the mounting / installation has to
be performed carefully. Additionally the device has
to be protected from the environmental effects by
the installation in a ventilated housing, with a much
higher ingress protection than the device. Check, if
the desired ingress protection is sufficiently for
your application. (recommendation: IP 65 at least)

- Install the device in such a way that it is protected
from direct solar irradiation. Direct solar irradiation
can lead to the permissible operating temperature
being overstepped in the worst case. Through this,
the operability of the device can be affected or
damaged. If the internal pressure increases due to
solar irradiation, temporary measurement errors
may occur.

- Install the device in such a way, that the gauge
reference, which is necessary for measuring, is
protected from dirt and moisture.

- Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of
the characteristic curve.

Provide a cooling line when using the device in steam
piping.

If there is any danger of damage by lightning or
overpressure when the device is installed outdoor, we
suggest putting a sufficiently dimensioned overpressure
protection between the supply or switch cabinet and the
device.

3.2 General installation steps

- Carefully remove the pressure measuring device from
the package and dispose of the package properly.

- Go ahead as detailed in the specific instructions below.

3.3 Installation steps for tube nozzle

- Slip your flexible tubes (∅ 4 mm) onto the tube nozzles
as far as possible.

3.4 Installation steps for G 1/4" acc. to EN 837

- Use a suitable seal, corresponding to the medium and
the pressure input (e. g. a cooper gasket).

- Ensure that the sealing surface of the taking part is
perfectly smooth and clean.

- Screw the device into the corresponding thread by
hand.

- Tighten it with a wrench (approx. 20 Nm).

4. Electrical installation

WARNING! Install the device in currentless environ­ments only!

6. Initial start-up

WARNING! Before start-up, the user has to check for
proper installation and for any visible defects.

WARNING! The device can be started and operated by
authorized personnel only, who have read and under­stood the operating manual!

WARNING! The device has to be used within the
technical specifications, only (compare the data in the
data sheet)!

7. Placing out of service

WARNING! When dismantling the device, it must
always be done in the depressurized and currentless
condition! Check also if the medium has to be drained
off before dismantling!

WARNING! Depending on the medium, it may cause
danger for the user. Comply therefore with adequate
precautions for purification.

8. Maintenance

In principle, this device is maintenance-free. If desired, the
housing of the device can be cleaned when switched of
using a damp cloth and non-aggressive cleaning solutions.

!

An incorrect cleaning can cause irreparable damages
on diaphragm. Never use spiky objects or pressured air
for cleaning the diaphragm.

9. Service / Repair

9.1

Recalibration

During the life-time of a transmitter, the value of offset and
span may shift. As a consequence, a deviating signal value
in reference to the nominal pressure range starting point or
end point may be transmitted. If one of these two phenom­ena occurs after prolonged use, a recalibration is recom­mended to ensure furthermore high accuracy.

9.2

Return

Before every return of your device, whether for recalibration,
decalcification, modifications or repair, it is necessary to
contact us to ensure a fast handling of your request. Please
inform us by sending an email to: [e-mail].
Include the number of devices sent and request a RMA.
Then clean the device and pack it shatterproof before send it
to BD SENSORS indicating the RMA.

10. Disposal

The device must be disposed according to the
European Directives 2002/96/EG and
2003/108/EG (on waste electrical and electronic
equipment) Waste of electrical and electronic
equipment may not be disposed by domestic
refuse!

WARNING! Depending on the measuring medium,
deposit on the device may cause danger for the user
and the environment. Comply with adequate precau­tions for purification and dispose of it properly.

11. Warranty conditions

The warranty conditions are subject to the legal warranty
period of 24 months from the date of delivery. In case of
