2 Safety instructions
• Please read this document prior to set-up of the unit� Ensure that the product is
suitable for your application without any restrictions�
• If the operating instructions or the technical data are not adhered to, personal
injury and/or damage to property can occur�
• Ensure before mounting the components into or removing them from the
compressed air system that the installation is at a standstill and no pressure is
applied�
• Improper or non-intended use may lead to malfunctions of the unit or to un-
wanted effects in your application� That is why installation, electrical connec-
tion, set-up, operation and maintenance of the unit must only be carried out by
qualified personnel authorised by the machine operator�
• In order to guarantee the correct condition of the device for the operating time
the device must only be used in media to which the wetted parts are sufficiently
resistant(→Technicaldata).
• The responsibility whether the measurement devices are suitable for the
respective application lies with the operator� The manufacturer assumes no
liability for consequences of misuse by the operator� Improper installation and
use of the devices result in a loss of the warranty claims�
3 Functions and features

4 Function
4.1 Process measured signals
• The unit displays the current process values�
• It generates 2 output signals according to the parameter setting�
OUT1: 4 selection options Parameter setting
- Switching signal for volumetric flow quantity limit
value
(→9.2.2)
- or switching signal for flow velocity (→9.2.2)
- or pulse signal for quantity meter (→9.3.1)
- or switching signal for preset counter (→9.3.2)
OUT2: 6 selection options Parameter setting
- Switching signal for volumetric flow quantity limit
value
(→9.2.3)
- or switching signal for flow velocity limit value (→9.2.3)
- or switching signal for temperature limit value (→9.4.1)
- or analogue signal for volumetric flow quantity (→9.2.4)
- or analogue signal for flow velocity (→9.2.4)
- or analogue signal for temperature (→9.4.2)
If not used as an output, OUT2 (pin 2) can instead be
used as an input for an external reset signal�
(→9.3.5)
4.2 Volumetric flow monitoring
The volumetric flow is monitored by a calorimetric measuring system, the meas-
ured signals are evaluated by the electronics�
• 2 switching signals for volumetric flow limit values can be provided (output 1
andoutput2).Ontheswitchingfunctions→4.5.
• An analogue signal which is proportional to the volumetric flow (4���20 mA) can
beprovidedonoutput2.Ontheanaloguefunctions→4.6.
4.3 Consumed quantity monitoring
The unit has an internal quantity meter which continuously totals the volumetric
flow quantity� The sum corresponds to the current consumed quantity since the
last reset�
• The current meter reading can be displayed�

7
UK
• In addition the value before the last reset is saved� This value can also be
displayed�
The meter saves the totalled consumed quantity every 10 minutes� After a
power failure this value is available as the current meter reading� If a time-
controlled reset is set, the elapsed time of the set reset interval is also saved�
So the possible data loss can be maximum 10 minutes�
• Overflow: After the maximum value (9 999 999 Nm³) the meter is reset to 0�
The meter can be reset as follows:
• Manualreset(→9.3.3).
• Time-controlledautomaticreset(→9.3.3).
• Externalinputsignalonpin2(→9.3.5).
4.3.1 Consumed quantity monitoring with pulse output
Output 1 provides a counting pulse each time the value set in [ImPS] is reached
(→9.3.1).
4.3.2 Consumed quantity monitoring with preset counter
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 t, output 1 switches and remains switched
until the counter is reset�
- If the quantity x is not reached after the time t has elapsed, the meter is auto-
matically reset and counting starts again; output 1 does not switch�
• Non time-dependent quantity monitoring�
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTo] = [OFF]�
- If the quantity x is reached, output 1 switches and remains switched until the
counter is reset�
4.4 Temperature monitoring
• A switching signal for temperature limit values can be provided on output 2� On
theswitchingfunctions→4.5.
• An analogue signal which is proportional to the temperature (4���20 mA) can be
providedonoutput2.Ontheanaloguefunctions→4.6.

4.5 Volumetric flow or temperature 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:
4.5.1 Hysteresis function
Normally open: [OUx] = [Hno]
Normally closed: [OUx] = [Hnc]
First the set point (SPx) is set, then the
reset point (rPx) with the requested
difference�
HY = hysteresis
4.5.2 Window function
Normally open: [OUx] = [Fno]
Normally closed: [OUx] = [Fnc]
The width of the window can be set by
means of the difference between SPx
and rPx�
SPx = upper value
rPx = lower value�
FE = window

9
UK
4.6 Volumetric flow or temperature monitoring / analogue
function
• Analogue start point [ASP] determines at which measured value the output
signal is 4 mA�
• 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�
Example of volumetric flow monitoring:

MEW = final value of the measuring range
In the set measuring range the output signal is between 4 mA and 20 mA�
It is also indicated:
Volumetric flow above the measuring range: output signal > 20 mA�
4.7 Adjustment to the internal pipe width
The unit can be used for different internal pipe widths� The selected internal pipe
widthmustbesetviathemenu(→9.2.1Adjustmenttotheinternalpipewidth).
Set the internal pipe widths before defining values for switching limits (SPx,
rPx) and analogue limit values (ASP, AEP)�
4.8 Set standard conditions of the volume flow
The unit is adjusted to a standard volume flow to DIN ISO 2533, i�e� volume flow
at 1013 hPa, 15 °C and 0 % relative air humidity�

The unit can be set to different standard conditions:
• Via the menu item [rEF�P] the standard pressure is set, which serves as a refer-
enceforthemeasuredanddisplayvaluesforvolumetricflow(→9.5.8).
• Via the menu item [rEF�T] the standard temperature is set, which serves as a
referenceforthemeasuredanddisplayvaluesforvolumetricflow(→9.5.9).
4.9 Low flow cut-off (LFC)
Withthisfunctionsmallvolumetricflowquantitiescanbeignored(→9.5.5).Flows
below the LFC value have no effect on the display and output signals�
4.10 Customer-specific calibration (CGA)
