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 car-
ried 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 regula-
tions. 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 variet
y
of process con-
nections, measurement ran
g
es, main boards and displa
y
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 desi
g
n, different transmitter versions
can be mounted (see “Model Ke
y
”on pa
g
e 79).
2.1.1 Pressure Transducer
The pressure transducer has a piezo-resistive or thinfilm measurement cell depend-
in
g
on the pressure ran
g
e. 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 inte
g
rated in the housin
g
contains the terminal compart-
ment and the ke
y
pad used for pro
g
rammin
g
the transmitter. The four ke
y
s must be
activated (unlocked) before use. Durin
g
normal operation the ke
y
pad is locked to pro-
tect data and functions previousl
y
entered. The ke
y
pad is automaticall
y
locked when
no ke
y
is hit for 10 minutes. The processin
g
unit converts the di
g
italized si
g
nal from
the measurin
g
unit into a standard 4...20 mA current si
g
nal.
2.1.3 Display Unit
The indicator has four di
g
its (7-se
g
ment displa
y
) + s
y
mbols. Below it, line 1 (16-se
g
-
ment displa
y
) is used to displa
y
error codes and the si
g
nal’s unit of measure. The unit
of measure can be selected b
y
the operator. Measurements over 9999 can not be cor-
rectl
y
displa
y
ed. Please note this when choosin
g
the unit (e.
g
. 9999 Pascal = 0,09999
bar). Additional information is displa
y
ed in lines 2 and 3 (16-se

g
op-
tions. These options include alarm status, dampin

tion and dia

es.
2.2 Function
The mode of operation for si
g
nal conversion works in the same wa
y
for all versions.
The pressure transducer converts the existin
g
pressure into an electrical si
g
nal. 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 pro
g
rammin
g
(parameterization) and the displa
y
of ex-
tended functions such as inversion, dampin
g
, alarm status and linearization.

All functions are pro
g
rammable once the pressure transmitter has been up
g
raded
with a displa
y
unit. The adjusted parameters are stored after the displa
y
unit is re-
moved.
The displa
y
unit can be rotated in 300°, so that it can be read under various installation
conditions. The housin
g
cover with built-in displa
y
can be fastened to the housin
g
at
all four side positions.
4.3 Housing Reconfiguration
Rotate the housin
g
of the displa
y
unit in order to be able to read the displa
y
from
above when the pressure transmitter is installed in an upri
g
ht position.
•Loosen the 4 internal hexa

lift off the housin
g
with the displa
y
unit.
•Carefull
y
turn the housin
g
b
y
180°.
•Re-ti
g
hten the screws.
When tightening the 4 hollow screws, make sure that they are ade-
quately and securely seated in order to ensure that the transmitter is
properly sealed.

4.4 Electrical Connection
The suppl

-
nal are transmitted via a two-wire cable (max. 12 mm outer diameter, max. 14 AWG)
and connected in accordance with the pin confi
g
uration.
Suppl
y
volta

e can be supplied b
y
a power unit, a transmitter power suppl
y
or b
y
means of a PLC connection.
It is su

Please observe local installation regulations (Germany: VDE-Standard).
The terminal voltage should not exceed 36 V.

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 pro
g
rammed without a displa
y
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 de-
fault 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 sen-
sor’s nominal pressure range, then span end-point is fixed at this peak val-
ue 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.
