Safety instructions
Read the product description before installing the unit. Ensure that the product is
suitable for your application without any restrictions.
Non-adherence to the operating instructions or technical data can lead to personal
injury and/or damage to property.
In all applications check compliance of the product materials (see Technical data)
with the media to be measured.
Controls and indicating elements
17-segment display Display of the system pressure,
display of parameters and parameter values.
22 x LED red Switching status; lights if output I / II has switched.
3Mode / Enter button Selection of the parameters and acknowledgement of
the parameter values.
4Set button Setting of the parameter values (scrolling by holding
pressed; incremental by pressing briefly).

Function and features
The pressure sensor detects the system pressure.•
It unit shows the current system pressure on its display,•
It generates 2 output signals according to the set output configuration.•
Output 1 Output 2
Analogue output
(only output 2)
I: 4 ... 20 mA
U: 0 ... 10 V

Avoid static and dynamic overpressure exceeding the given overload
pressure.
Even if the bursting pressure is exceeded only for a short time the unit can
be destroyed (danger of injuries)!

Operating modes
Run mode
Normal operating mode
At power on the unit is in the Run mode. It carries out its measurement and
evaluation functions and provides output signals according to the set parameters.
The display shows the current system pressure (can be deactivated). The red
LEDs indicate the switching state of the outputs.
Display mode
Indication of parameters and the set parameter values
When the “Mode/Enter” button is pressed briefly, the unit passes to the Display
mode which allows parameter values to be read. The internal sensing, processing
and output functions of the unit continue as if in Run mode.
The parameter names are scrolled with each pressing of the “Mode/Enter”•
button.
When the “Set” button is pressed briefly, the corresponding parameter value is•
displayed for 15 s. After another 15 s the unit returns to the Run mode.
Programming mode
Setting of the parameter values
While viewing a parameter value pressing the “Set” button for more than 5 s
causes the unit to enter the programming mode. You can alter the parameter
value by pressing the “Set” button and confirm the new value by pressing the
“Mode/Enter” button. The internal sensing, processing and output functions of the
unit continue as if in Run mode with the original parameter values unless a new
value is confirmed. The unit returns to the Run mode when no button has been
pressed for 15 s.

Installation
Before mounting and removing the sensor, make sure that no pressure is
applied to the system.
The unit is adaptable for various
process fittings by Aseptoflex
adapters (to be ordered separately as
accessories).
Mount adapter (C) to the sensor first,
then sensor + adapter to the process
connection by means of a nut, a
clamping flange or similar (B).
C
A
B
A = freely rotatable housing
If it is not possible to slide the fixing element (B) down over the top of the sensor:
slide it up over the bottom of the sensor before the adapter is mounted.
NOTE: A guarantee for a long-term stable and maintenance-free fitting, with no
bug traps in the hygienic sealing of the metal seal (Aseptoflex connection) is only
valid for once-only mounting.
Welding adapter
Weld the adapter first. Then mount the sensor.
8
Mounting of the Aseptoflex adapter
Step 1
Grease thread and sealing chamfer of
the sensor and of the adapter with the
greasing paste supplied.
The greasing paste is food-grade
(USDA-H1 84-201).
Make sure that the O-ring (D) is
correctly positioned.

1 = Grease
Step 2
Screw the sensor into the adapter.
Avoid mechanical influence on the
sealing chamfers.
�
Step 3
Clamp sensor and adapter into a
clamping device (E). The sealing
chamfers (F) must not be damaged.
Tighten the sensor with a spanner until
you can feel the end stop.

If you continue to turn, this can have adverse effect on the sealing.

Electrical connection
The unit must be connected by a suitably qualified electrician.
The national and international regulations for the installation of electrical
equipment must be observed.
Voltage supply to EN50178, SELV, PELV.

Programming
1
Mode/Enter Set
Press the Mode/Enter button several
times until the respective parameter is
displayed.
2
Mode/Enter Set
Press the Set button and keep it
pressed. The current parameter value
flashes for 5 s, then the value is
increased* (incremental by pressing
briefly or scrolling by holding pressed).
3
Mode/Enter Set
Press the Mode/Enter button briefly
(= acknowledgement).
The parameter is displayed again, the
set parameter value becomes effective.
4Change more parameters:
Start again with step 1.
Finish programming:
Wait for 15 s or press the Mode/Enter
button until the current measured value
is indicated again.
*Decrease the value: Let the display of the parameter value move to the maximum setting
value. Then the cycle starts again at the minimum setting value.
Select the display unit (Uni) before setting the switch points (SPx, rPx) or the limits for the
analogue output signal (ASP, AEP). This avoids rounding errors generated internally during
the conversion of the units and enables exact setting of the values.
If no button is pressed for 15 s during the setting procedure, the unit returns to the Run
mode with unchanged values.
The unit can be electronically locked to prevent unwanted adjustment of the set
parameters: Press both pushbuttons for 10 s (the unit must be in Run mode).
Indication goes out briefly (acknowledgement of locking / unlocking).
Units are delivered from the factory in the unlocked state.
With the unit in the locked state is indicated briefly when you try to change
parameter values.
