Thank you for choosing NIVELCO instrument
We are sure that you will be satisfied throughout its use!
1 INTRODUCTION
NIVOPRESS D-5/600 series transmitters are suitable for pressure and hydrostatic pressure (level) gauging of ordinary and hazardous gases, fumes, liquids and
masses. Devices can be used for measuring in clean technologies and also for mediums tending to obturation. Intelligent electronics and HART communication
provides application possibilities for the most different tasks.

4.1 WIRING
–
–
• Transmitters are used in 2-wire systems with power supply of
10 … 36 V DC. Resistance of the units in the loop depends on the
voltage of the power supply.
• For wiring shielded cable suggested in the Technical Data should be
used.
• After removal of the housing cover and taking out the display
module (if any), the screw terminals can be accessed. Cover of the
flame proof housing can be removed after unhooking the clamp.
• The unit should be grounded by the inner or outer grounding screw..
• Switch on the unit and make necessary programming.
• After programming ensure proper sealing and closing of the cover
(and fastening of the clamp with the flame proof models).
The unit may be damaged by electrostatic discharge (EDS) via its terminal, thus apply the precautions commonly used to avoid electrostatic
!
discharge e.g. by touching a properly grounded point before removing the cover of the enclosure.

5 PUTTING INTO OPERATION, PROGRAMMING
Transmitter installed and wired correctly will after powering operate
according to the settings of the Manufacturer (Default).
Operability is indicated by lighting of the LED VALID.
The value of the actual loop current can be measured by a voltage
meter (set for 200 mV range) with an accuracy of 0,5 %. 4 mV
corresponding to 4 mA and 20 mV corresponding to 20 mA.
This procedure can not be used for calibration..
WARNING! During installation the zero point of the transmitter can
possibly shifted. Therefore the zero point has to be checked and
eventually be corrected as described in the programming
(See P7 in 5.1.3).

5.1 PROGRAMMING
Adjustment of the unit to the conditions of the application will be carried out by programming parameters with the aid of the push buttons and following the
procedure on the display of the SAP-203 module. The NIVOPRESS is fully operational without the SAP-203 it is only needed for programming and/or displaying
measurement values. Manufacturer’s setting is as below:
DEFAULT
− Measurement: pressure
− Engineering units:bar, for the range of p > 0,6 barmbar, for the range of p ≤ 0,6 bar
− Current output (4 … 20 mA),
− Damping: 3 s
− Error indication: I
= 3,8 mA
out
NIVOPRESS DB- types are incorporating SAP-203 display module but the types DT- are not.
If the default is not meeting application requirements or the unit should be used for level measurement the programming i.e. modification of the parameters is
needed. This can be performed with the SAP-203 display module. (Obviously for programming of the DT series the plug in of the SAP-203 module is necessary.)
The unit will measure during programming in accordance with the parameters set previously. The new, modified parameters will only be effective
after returning to the Measurement Mode.
If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 3 minutes and will operate with the parameters
entered during the last completed programming.

5.1.3 Parameters – descriptions and programming
WARNING! During installation the zero point of the transmitter may be shifted. It is suggested to make a correction in P7
P0:- - - a Assignment of 4 mA to the measured (lowest) value
P1:- - - aAssignment of 20 mA to the measured (highest) value
The lowest and highest (limit) value of the (pressure or level) range is to be assigned to the 4 and 20 mA output current. This can be performed
by two methods
a: manually i.e. by entering the relevant values in P0 and P1 (Make sure that values to be programmed does not exceed the range of the unit in
question, the modification of the parameter value will not be accepted i.e. after pressing E the parameter value will remain blinking.)
The procedure for assignment of 4 mA to 0 bar in P0: press
parameter value, enter 0 as lowest pressure value and press
programming/return to measurement mode).
b: automatically i.e. using the GET VALUE function at being in P0 and P1. This method for which the sensor should be put under the required
(zero and high limit value) pressure or the relevant level in the tank should be available, provides higher accuracy.
FACTORY DEFAULT: limit values of the (pressure) range of the unit in question
P5:- - - aDensity [kg/m3 or lb/ft3]
Selectable between 600 and 2000 kg/m
FACTORY DEFAULT: 1000 kg/m

P6:- - - aGravitational acceleration [m/s2 or ft/s2]
For calculation of the level the gravitational acceleration should be entered if it is substantially different as the default value.
FACTORY DEFAULT: 9,806 m/s
2
P7: - - - aZero point correction and offset
As mentioned above the zero point correction is advised to perform once the unit is installed already. This can be best done with using the GET
VALUE function in P7 having zero pressure on the sensor. (press
to parameter value, press + GET VALUE to make the unit recognise the actual 0 bar, press E to go back to the parameter address,
E
+
finally press
to exit programming/return to measurement mode provided no other programming is needed)
With this procedure shift of the zero point will be displayed (with its – or + sign) and corrected.

The zero point of the transmitter can be shifted (offset) within and outside of the range, which might be useful instrument for special level gauging
applications. This can also performed in the parameter P7.
Zero point of the transmitter can be shifted up to the 50% of the range. Doing so the active measurement
range will be reduced by the distance of „e”
Since in this case result will be achieved by deducting “e” from the measured level “h” for manual
h
0 m
e
programming (provided the zero point has not been shifted during installation!) the value of the zero offset “-e”
should simply be entered in P7.
With programming zero offset the possible zero point shift (occurred during installation) should also be taken
into consideration with its mathematical sign. If for instance with the first switch-on checking of zero point in P7
would show a shift of for instance - 0,027* and zero point has to be offset by one meter –1 and ---- 0,027 i.e. 1,027 should be entered in P7
For automatic programming the required “0” level should be achieved and the GET VALUE used as described
section P1
* this value with its – or + sign can be seen during Zero Point Correction
Zero point of the transmitter can also be shifted (offset) outside of the range. This is a virtual extension of the
range by adding a dead zone of „e” in which no measurement will take place consequently current output
remains the same and the value of „e” will be displayed. The measurement will only be active in the range of
„h” however the value of „e” will be added to the level measured.
Since the result will be achieved by adding “e” to the measured level “h” for the manual programming (provided
h
the zero point has not been shifted during installation!) the value of the zero offset “(+)e” should simply be
entered in P7.
With programming zero offset the possible zero point shift (occurred during installation) should also be taken
0 m
e
into consideration with its mathematical sign. If for instance with the first switch-on checking of zero point in P7
would show a shift of for instance - 0,027* and zero point has to be offset by one meter (+)1 and ---- 0,027 i.e.
0,973 should be entered in P7
Obviously in this case there is no place for automatic programming.
* this value with its – or + sign can be seen during Zero Point Correction
