2 Safety instructions
• Please read this document prior to installing the unit� Ensure that the product is
suitable for your application without any restrictions�
• Work on compressed air equipment as well as mounting, setting for operation
and set-up of the unit must be carried out by suitably qualified personnel� When
doing so, state of the art, safety and accident prevention regulations must be
adhered to�
• Ensure that the installation is at a standstill and no pressure is applied before
mounting components into or removing them from compressed air equipment�
• Improper or non-intended use may lead to malfunctions of the unit or to
unwanted effects in your application� That is why installation, electrical con-
nection, set-up, operation and maintenance of the unit must be carried out by
qualified personnel authorised by the plant operator�
• Inallapplicationstestthecompatibilityoftheproductmaterials(→11Technical

3 Functions and features
The unit monitors the standard volume flow of operating compressed air�
It detects the 3 process categories volumetric flow, consumed quantity, medium
temperature�
Applications: compressed air equipment�
All data refer to standard volume flow according to DIN ISO 2533, i�e� volume flow
at 1013 hPa, 15°C and 0% relative air humidity�
The general operating conditions of compressed air equipment apply�
Pressure Equipment Directive (PED): Devices with a measuring section comply
with art� 3 sec� (3) of the Directive 97/23/EC and are designed and manufac-
tured for stable gases of the fluid group 2 in accordance with sound engineering
practice�
4 Function
4.1 Processing of the measured signals
• The unit displays the current process values�
• It generates 2 output signals according to the parameter setting�
OUT1: 3 selection options ����������������������������������������������������� parameter setting
switching signal for volumetric flow limit values ����������������������������������(→9.2.1)
or pulse sequence for totalising meter ������������������������������������������������(→9.3.1)
or switching signal for preset counter �������������������������������������������������(→9.3.2)
OUT2: 2 selection options
switching signal for volumetric flow limit value �����������������������������������(→9.2.2)
or analogue signal for volumetric flow ������������������������������������������������(→9.2.3)
4.2 Volumetric flow monitoring
The flow rate is monitored by a calorimetric measuring system, the measured
signals by the electronics�
• 2 switching signals for volumetric flow limit values can be provided (output 1
andoutput2).Fortheswitchingfunctions→4.5.
• An analogue signal proportional to the volumetric flow (4���20 mA) can be
providedonoutput2.Fortheanaloguefunctions→4.6.

4.3 Consumed quantity monitoring (totalizer function)
The unit has an internal quantity meter which continuously totals the volumetric
flow� The sum corresponds to the current consumed quantity since the last reset�
• The current meter count can be indicated�
• In addition the value before the last reset is stored� This value can also be
indicated�
The meter saves the totalled consumed quantity every 10 minutes� After a power failure
this value is available as the current meter count� If a time-controlled reset is set, the
elapsed time of the set reset interval is also stored� So the possible data loss can be
maximum 10 minutes�
The meter can be reset as follows:
• Manualreset(→9.3.3).
• Time-controlledautomaticreset(→9.3.3).
4.3.1 Consumed quantity monitoring with pulse output
Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→9.3.1).
4.3.2 Consumed quantity monitoring with preset meter
2 types of monitoring are possible:
• Time-dependent quantity monitoring
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTo] = time t�
- If the quantity x is reached during the time t, output 1 switches and remains
switched until the meter is reset�
- If the quantity x has not been reached after the time t, the meter is automati-
cally reset and counting starts again; output 1 does not switch�
• Quantity monitoring not time-dependent
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTo] = [OFF]�
- If the quantity x is reached, output 1 switches and remains switched until the
meter is reset�
4.4 Monitoring of temperatures
• The unit detects the current system temperature and shows it on the display
(→chapter10.2ChangingthedisplayunitintheRunmode).
4.5 Volumetric flow monitoring / switching function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx)� The following switching functions can be selected:
• Hysteresis function / normally open (fig� 1): [OUx] = [Hno]�

7
UK
• Hysteresis function / normally closed (fig� 1): [OUx] = [Hnc]�
First the set point (SPx) is set, then the reset point (rPx) at the requested
distance�
• Window function / normally open (fig� 2): [OUx] = [Fno]�
• Window function / normally closed (fig� 2): [OUx] = [Fnc]�
The width of the window can be set by means of the distance between SPx and
rPx� SPx = maximum value, rPx = minimum value�
1 2
HY = hysteresis; FE = window
When set to the window function the set and reset points have a fixed hysteresis of 0�25 %
of the final value of the measuring range� This keeps the switching state of the output stable
if the volumetric flow varies slightly�
4.6 Volumetric flow monitoring / analogue function
• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA�
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the
measuring range�

8
Factory setting Measuring range scaled
MEW = final value of the measuring range
In the set measuring range the output signal is between 4 and 20 mA�
It is also indicated:
•Volumetric flow above the measuring range: output signal > 20 mA�
•Flow rate below the measuring range: output signal between 3�6 and 4 mA�
5 Installation
The rules and regulations for the installation and operation of compressed
air equipment must be observed�
5.1 Installation location
• Behind the cold dryer / near the load�
• If compressed air is fed into the main pipe through parallel pipes, the unit
should be mounted in the main pipe�
• Installation after the maintenance unit is also possible� If oil is used for the
loads, the unit must be mounted before the oiler�
5.2 Installation conditions
To achieve the specified measurement accuracy, the following mounting condi-
tions must be adhered to: defined inflow / outflow pipe lengths, defined flow cross-
sectional area, fixed installation depth and correct positioning of the measuring
elements�
The unit is delivered mounted on a pipe section meeting these conditions�

9
UK
In case of turbulances at the inflow side additional baffled pipes (B) are recom-
mended:
changes to the pipe diameter B = 15 x pipe diameter
90° elbow B = 15 x pipe diameter
two 90° elbows, one plane B = 20 x pipe diameter
two 90° elbows, two planes B = 25 x pipe diameter
valve, slide B = 45 x pipe diameter
5.3 Mounting position
• Permitted mounting positions: pipe length vertical, any position (fig� 1, 2), pipe
length horizontal, unit vertical (fig� 3, 5), unit on side, pipe length right (fig� 4)�
• Avoid the mounting position shown in fig� 6 (unit on side, pipe length left)� If the
flow rate is low, the specified measurement accuracy cannot be adhered to�

5.4 Installation in pipes
Integrate the pipe length so that the direction of flow (1) and the marking arrow (2)
show in the same direction�
6 Electrical connection
The unit must be connected by a qualified electrician�
The national and international regulations for the installation of electrical
equipment must be adhered to�
