NIVELCO NIPRESS D-300 Series User manual

IBExU: pending ●drc3612a0600h_05 ●1/3
Thank you for choosing NIVELCO instrument
We are sure that you will be satisfied throughout its use!
1. APPLICATION
The NIPRESS D-300 series pressure transmitter measures pressure and converts it into voltage or current. It
can be used in 2- and 3-wire systems. The wide choice of the models makes it suitable for many pressure
measurement tasks whether relative or absolute pressure, static or dynamic measurement is required. Two
different accuracy classes are available.
The design of the transmitter, the wide temperature range and high overload capability and the possibility to
install the unit in any position, allows their application in many different industrial circumstances.

3. INSTALLATION
Due to its small size and weight NIPRESS D-300 can be directly installed on
tanks, pipes, machines, etc. without mounting device.
To provide a chance for replacement of the instrument during operation the use
of closing armature is recommended. A simple ball valve will be suitable for
lower pressure and for higher pressure (above 6 bar g) a three-way blow-off
needle-valve can be suggested. With pressure measurements of medium with
temperature over 75 °C (167 °F), the application of condensing device would
protect the instrument against overheating and extends its lifetime.
The temperature of the condensation in the condensing devices (in the water
lodge) is practically only 10 … 20 °C (18 … 36 °F) higher than the ambient
temperature.
Using longer impulse tube its proper sloping for the necessary de-aerating and
emptying has to be ensured.
Measuring low pressure values in systems with substantial height difference
between the transmitter and place of measurement the hydrostatic pressure of
the medium in the impulse pipe should be taken into consideration. In case of
outside installation, the unit should be protected against rain or splash water,
because malfunction may occur if the connector’s screw is not tightened
properly (i.e. not appropriate sealing).
Installation position: The pressure transmitter has been calibrated in a vertical
position with the pressure port facing down. If this position changes during
installation, a slight deviation from the zero point may occur in the measured
value.
3.1 INSTALLATION INSTRUCTION
For mounting and dismantling SW27 open-end torque wrench should be used.
The cylindrical housing of the transmitter should not be gripped and
tightened with a pipe wrench!
The plug-in electric connector can be unplugged after releasing and removing
its fastening screw. The connection insert can be pushed out by a screw driver
from the direction of the screw.
Pushing the electric cable through the cable gland it can be connected to the
relevant points of the connector. Make sure that the cable gland and sealing
plate of the connector is tightened properly.
For the sake of noise suppression, the transmitter housing is grounded. If the
grounding of the appliance with the pressure transmitter is appropriate, no
further action will be needed, else, the grounding should be performed.
Installation steps:
The specified tightening torques must not be exceeded!
Tightening torques:
1/4” BSP: max. 5 Nm; 1/2” BSP: max. 10 Nm; 3/4” BSP: max. 15 Nm;
1” BSP: max. 20 Nm; 1 1/2" BSP: max. 25 Nm.
Mounting steps for BSP thread connections according to DIN 3852:
Do not use any additional sealing material such as teflon tape! Check if the
O-ring is undamaged, it has a flawless and clean surface and seated in the
designated groove. Screw the device into the corresponding thread by hand,
and tighten the parts with a suitable torque wrench.
If your device can be secured with a knurled ring, the pressure transmitter
should only be tightened by hand.
Mounting steps for NPT thread connections:
Use a suitable sealant (e.g. PTFE tape). Turn the device by hand to the correct
thread and tighten it with an open-end torque wrench.
4. WIRING
Shielded and twisted multicore cable is recommended for the electrical
connection. For devices with cable gland, you have to make sure that the
external diameter of the used cable is within the allowed clamping range. After
you have connected the wires, tighten the gland screw firmly until proper
sealing.
For the installation of a device with integral cable, following bending radiuses
have to be complied with:
Cable without ventilation tube:
-static installation: 5-fold cable diameter
-dynamic application: 10-fold cable diameter
Cable with ventilation tube:
-static installation: 10-fold cable diameter
-dynamic application: 20-fold cable diameter
In case of devices with integral cable and integrated ventillation tube, the PTFE
filter located at the cable end on the air tube must neither be removed nor
damaged.

5. SPECIAL CONDITIONS OF SAFE USE
Before turning the device on, make sure the installation is complete and there
are no visible defects. The device may only be used within the limitations
specified in the technical specifications.
The device connector must be installed in such a way that the IP20 level of
protection always remains.
Ex ia certified transmitters can only be operated in qualified, certified and
approved galvanically isolated intrinsically safe Ex ia circuits complying with the
technical data and the device’s explosion protection marking.
The metal housing of the device must be connected to the EP network.
6. TROUBLESHOOTING
Fault Possible causes Fault detection / remedy
No output signal:
Connected incorrectly. Check the connections!
Conductor/wire breakage. Check all wires with cable tester!
Defective measuring
device (signal input).
Check the amperemeter (and its
fuse) and the analog input of the
signal processing unit!
Analog output signal
too low:
Load resistance too high. Check the value of the load
resistance!
Supply voltage too low. Check the power supply and
power /current on the
transducer/transmitter!
A slight shift of the
output signal:
The diaphragm of the
sensor is severely
contaminated.
Cleaning with non-aggressive
cleaning solutions, soft brush or
sponge.
The diaphragm of the
sensor is calcified or
crusted.
It is recommended to clean
carefully and remove dirt.
A large shift of the
output signal:
The diaphragm of the
sensor is damaged
(caused by overpressure
or mechanically).
Check the diaphragm of the
sensor, if it is damaged then send
the device back to the
manufacturer!
7. MAINTENANCE AND REPAIR
The instrument does not require regular maintenance. Repair will be carried out
at the NIVELCO' premises only. When dismantling the device, it must always
be done in depressurized and currentless condition! Check also if the medium
has to be drained off before dismantling.
After the device has been properly shut down, if necessary, clean the
diaphragm carefully with a non-aggressive cleaning solution, soft brush or
sponge.
Wrong cleaning or improper touch may cause irreparable damage to the
diaphragm. Therefore, never use pointed objects or pressured air for cleaning
the diaphragm.
Before returning your device for repair, it has to be cleaned carefully,
neutralize/decontaminate the harmful substances at the media wetted parts. In
addition, a form must be enclosed with the device, declaring that the device is
free from all contaminants and substances hazardous to health. The form (B
0407 / C – Returned equipment handling form) can be downloaded from our
web site: www.nivelco.com.
