1 General Safety Instructions

All pressure connections may only be opened after the system is
without pressure!

Observe the national regulations about safety and accident prevention , as
well as the safety instructions in this operating manual when operating the
pressure transmitter.

Any operation not described in the following instructions must not be car­ried out.

If a failure cannot be repaired, the transmitter must be switched off. The
operator must then make sure that it is only switched on again after the
failure has been repaired.

Prior to installing, starting and operating a pressure measuring instrument,
the user must ensure that the appropriate instrument has been selected
with regard to scale range and performance and that the wetted parts
material is suitable for the specific measuring conditions of the respective
application.

Serious injuries and/or damage can occur should the relevant regulations
not be observed.

Dangerous pressure media such as oxygen, acetylene, flammable gases
or liquids and toxic gases or liquids as well as instruments for refrigeration
plants or compressors etc. require attention above the standard regula­tions. Here the specific safety codes or regulations must be considered.

Ramaining pressure medium contained in the pressure element may be
hazardous or toxic. This should be considered when handling and storing
the removed pressure measuring instrument.

Repairs should only be carried out by the manufacturer. All other repairs or
modifications of the transmitter are unauthorized.

Other important safety guidelines can be found in the different sections of
this instruction manual.

2 Product Description

The UniTrans pressure transmitter can be used in level control applications as well as
for pressure measurement applications in process industr

y

. A variety of process con-

nections, measurement ran

g

es, main boards and display options result in a product

for a wide ran

g

e of applications.

2.1 Construction

The UniTrans consists of a pressure sensor, a control interface unit and a housin

g

cover with optional displa

y

. Due to this modular design, different transmitter versions

can be mounted (see “Model Ke

y

” on page 79).

2.1.1 Pressure Transducer

The pressure transducer has a piezo-resistive or thinfilm measurement cell depend­in

g

on the pressure range. The sensors are temperature compensated, and have a

hermeticall

y

welded membrane which is "helium" leak-tested. The pressure trans-

ducers do not have internal sealin

g

elements.

Pressure transducers further distin

g

uish themselves from one another based on their

pressure ran

g

es and the different materials of wetted parts. Different process

connections can be selected to serve a wide ran

g

e of applications.

Never exceed the overpressure limit of the respective pressure transducer.

2.1.2 Processing Unit

The processin

g

unit, which is integrated in the housing contains the terminal compart-

ment and the ke

y

pad used for programming the transmitter. The four keys must be

activated (unlocked) before use. Durin

g

normal operation the keypad is locked to pro-

tect data and functions previousl

y

entered. The keypad is automatically locked when

no ke

y

is hit for 10 minutes. The processing unit converts the digitalized signal from

the measurin

g

unit into a standard 4...20 mA current signal.

2.1.3 Display Unit

The indicator has four di

g

its (7-segment display) + symbols. Below it, line 1 (16-seg-

ment displa

y

) is used to display error codes and the signal’s unit of measure. The unit

of measure can be selected b

y

the operator. Measurements over 9999 can not be cor-

rectl

y

displayed. Please note this when choosing the unit (e.g. 9999 Pascal = 0,09999

bar). Additional information is displa

y

ed in lines 2 and 3 (16-segment display). The

operator can enter commands in the pro

g

ramming mode on the display unit by means

of menu

Transmitters with displays offer a larger number of programming and processing op­tions. These options include alarm status, dampin

g

, signal inversion, tank lineariza-

tion and dia

g

nostic messages.

2.2 Function

The mode of operation for si

g

nal conversion works in the same way for all versions.

The pressure transducer converts the existin

g

pressure into an electrical signal. Mi-

croelectronics further process the input si

g

nal and produce a proportional 4-20 mA

standard si

g

nal.

The displa

y

-version allows programming (parameterization) and the display of ex-

tended functions such as inversion, dampin

g

, alarm status and linearization.

5 Operation of Transmitters without Display

5.1 Preparation

This unit can be pro

g

rammed before or after installation.

• Connect an ampere meter to the device’s output (between terminals I and L+).

• Note that after each action, a brief oscillation/deflection of 20 mA occurs (verifica-

tion of a successful action).

The followin

g

functions can be programmed without a display unit:

• Zero point adjustment with a full or empt

y

container (with/without pressure)

• Span adjustment with a full or empt

y

container (with/without pressure)

• Inte

g

ration time

• Reset to manufacturer’s defaults

5.2 Key Functions (only available for transmitters without display)

An error signal is caused by a current surge (21 mA or 3.6 mA; 5 sec) when
the zero point or span setting fall outside of the sensor’s nominal pressure
range during adjustments with existing pressure. No values are stored.
The keypad becomes inactive after 10 min. of disuse. All settings will de­fault to previously stored values. Only settings that have been confirmed
with the "OK" function are stored.

5.3 Calibration with Pressure

5.3.1 Zero Point Calibration

5.3.2 Span Calibration

Calibration of the measurement ran

g

e (span).

Make sure that the pressure to be used as the zero point (P 0 %), is
present at the transmitterer diaphragm before calibration.

Make sure that the pressure to be used as the span end-point (P 100 %) is
present at the transmitter diaphragm. The measuring range between zero
and end value of span is saved as span.

A change in the zero point has no effect on the calibrated span.
However, if the span end-point is higher than the peak value of the sen­sor’s nominal pressure range, then span end-point is fixed at this peak val­ue and the span is reduced accordingly.
A change in the span setting has no effect on the zero point. The zero point
and span end-point must fall within the sensor’s nominal pressure range.
A mounting correction must not be carried out when making an adjustment
with pressure (wet adjustment). Otherwise, the mounting correction must
be carried out before saving the zero point and the end value of span.

5.4 Calibration without Pressure

Determine the current reference values for the zero point and the span to be entered
in the transmitter before calibration. This is done as follows:

5.4.1 Zero Point Calibration

• Determine the h

y

drostatic pressure of the liquid’s surface that meets the zero point.

• Adjust this pressure in proportion to the sensor’s nominal pressure ran

g

e.

• Multipl

y

this proportion by 16 mA and add 4 mA to the result.

This produces the calculated current (value I

calc

), which is entered in the transmitter

and used to pro

g

ramm the zero point (0%).

Example:

A pressure transducer with 0 ... 400 mbar (nominal pressure) needs to be pro-

g

rammed.The liquid’s surface (with a density of 1) is 1 m above the diaphragm at the

zero point producin

g

a pressure of 100 mbar.

This means that the device’s current value must be set to 8 mA when performin

g

a dry

(empt

y

) calibration.

5.4.2 Span Calibration

• Determine the h

y

drostatic pressure of the liquid’s surface, which corresponds to the

span end-point.

• Calculate the difference of the pressure value between span end-point and zero
point and divide this difference b

y

the nominal pressure range of the sensor.

• Multipl

y

this proportion by 16 mA and add 4 mA to the result.

This produces the calculated current (value I

calc

), which is entered in the transmitter

and used to pro

g

ram the span end-point (100%).

The measurement ran

g

e between zero point and span end-point will be stored as

span.

Example:

A pressure transmitter with 0 ... 400 mbar (nominal pressure) is to be programmed.
The liquid’s surface (with a densit

y

of 1) is 1 m above the diaphragm at the zero point.

The maximum (span end-point) should be 3 m. The measurin

g

range (span) is 200

mbar.

This means that the output must be set to 12 mA durin

g

programming.

5.4.3 Mounting correction of the sensor

The position of the measurin

g

cell ist adjusted by simultaneously pressing (2 sec.) the

"zero" and "esc" buttons.

A change in the zero point has no effect on the adjusted span.
However, if the span end-point is higher than the peak value of the
transmitter’s nominal pressure range, then the span end-point is fixed
at this peak value and the span is reduced accordingly.
A change in the span setting has no effect on the zero point. The zero
point and span end-point must fall within the transmitter’s nominal
pressure range.

A test / correction of the zero point is suggested after adjusting the
span in order to maintain optimum accuracy.
A mounting correction should be carried out before or after making an
adjustment without pressure (dry adjustment) (see 5.4.3). The trans­mitter must therefore be placed in the reference position for the mea­surement (installation site) without pressure on the diaphragm.

6.5.2 Main Menu: Calibration of zero and span

A single pressure value is set for the zero point or the span end-point
within the sensor’s nominal pressure range, and assigned to the associ­ated output current signal when making adjustments with existing pres­sure. An error signal occurs when the existing pressure lies outside of
the sensor’s nominal pressure range. The value is not saved in this
case.

A mounting correction should be performed before or after making an
adjustment without pressure (dry adjustment) (see 6.5.6). The sensor
must therefore be placed in the reference position for the measurement
(installation site) without pressure on the diaphragm.

A mounting correction is unnecessary when making an adjustment with
pressure (wet adjustment). Otherwise, the mounting correction must be
performed before saving the zero point and span end- point.

A test / correction of the zero point is suggested after adjusting the
span in order to maintain optimum accuracy.

A change or correction in the density causes a change in the span end­point’s unit of measure (mm, m, inch, feet). The span end-point must be
re-calibrated when changing the medium to be measured (due to a
change in density).
