3 Installation
3.1 Mounting nd afety a s instructions
WARNING! This device may only be installed by
qualified technical personnel who have read and
understood the operating manual!
WARNING! Install the device only when depres-
surized and current free- !
!Handle this device with care, both in ed and packag
unpackaged condition!
!No modifications/changes should be made on the
device.
!Do not throw the device!
!Do not use any force when installing the device, to
prevent damage of the device and the plant!
!Avoid of sources interference (transformers,
transmitters, motors etc.) or sources of heat in the
surrounding area .
!Shocks or vibrations at the mounting connection
can cause distortions to the output signals.
3.2 Installation steps
- Carefully remove the pressure measuring device
from its package and dispose of the package prop-
erly.
- Mount the device in a suitable location using both
straps. The corresponding dimensions are provided
under "6".
- Connections should be vertical, i. e. the pressure
connections should point downwards. The sensors
are calibrated in the factory for these mounting con-
ditions. In addition, the formation of condensation in
the pressure tubing of the sensor is also reduced.
- Use the appropriate hoses for the connection.

3.3 installation Electrical
WARNING! This device may only be installed by
qualified technical personnel who have read and
understood the operating manual!
- Open the top cover and establish the electrical
connection of the device according to the follow-
ing description. Screw the top cover onto the box
again.
- Guide externally the power supply line through
the right so that the wires can cable fitting be
connected with the right terminal block (SUP-
PLY) without any problem.
- Next, tighten the cable gland by hand. Make
sure, however, that the cable is strain-relieved.
3.4 Pressure port
- Connect the hose with the higher pressure to the
right hand (positive) pressure port.
- Connect the hose with the lower pressure to the
left hand (negative) pressure port.
4 - Initial start up
After switching on the power supply, the output
signal can be measured. Variations in the output
signals may have two possible causes:
1. The warm up time of the sensor is about 30min- .
After this period, the sensor signal should be
stable for zero differential pressure and constant
ambient temperature.
2. For small pressure ranges, a slight deviation in
the zero point due to ambient conditions can oc-
cur. This error can be corrected by adjusting the
zero-point potentiometer of the sensor after the
warm- up time. (Set the output signal of the sen-
sor with both pressure inputs open to the nomi-
nal value.)
5 Operation
5 .1 General information
WARNING! - check Before start up, the user must
to ensure proper installation and for any visible de-
fects.
WARNING! The device may only be started and
operated by authorized personnel who have read
and understood the operating manual!
WARNING! The device may only be used within
the technical specifications the data in the (see
data sheet)!
WARNING! – Do not touch the bonding wires this
ca . n destroy the device
5.2 Setting of damping
P otentiometer for setting the damping is located
adjacent to the display on the left (see image 2).
The damping of the device can be set by turning a
size 2 Phillips screwdriver in the area of 0 to
5000ms.
