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�

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

andoutput2).Fortheswitchingfunctions→4.5.

• An analogue signal proportional to the volumetric flow (4��20 mA) can be

providedonoutput2.Fortheanaloguefunctions→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:

• Manualreset(→9.3.3).

• Time-controlledautomaticreset(→9.3.3).

4.3.1 Consumed quantity monitoring with pulse output

Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→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

(→chapter10.2ChangingthedisplayunitintheRunmode).

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]�

• 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�

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�

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�

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�

show in the same direction�
