Safety instructions2

Please read this document prior to set-up of the unit� Ensure that the product is•

suitable for your application without any restrictions�

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�

Checkthecompatibilityoftheproductmaterials(→12Technicaldata)withthe•

media to be measured in all applications�

For the scope of validity cULus:

The device shall be supplied from an isolating transformer having a secondary

Functions and features3

The unit monitors water and aqueous media�

It detects the 3 process categories volumetric flow, consumed quantity, medium

temperature�

Function4

Processing of the measured signals4.1

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 quantity limit value ��(→9.2.1)

or pulse sequence for quantity meter ��(→9.3.1)

or switching signal for preset counter ��(→9.3.2)

OUT2: 4 selection options

Switching signal for volumetric flow quantity limit value ��(→9.2.2)

or switching signal for temperature limit value ��(→9.4.1)

or analogue signal for volumetric flow quantity ��(→9.2.3)

or Analogue signal for temperature ��(→9.4.2)

Volumetric flow monitoring4.2

2 switching signals for volumetric flow limit values can be provided (output 1•

andoutput2).Fortheswitchingfunctions→4.7.

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

beprovidedonoutput2.Fortheanaloguefunctions→4.8.

Consumed quantity meter4.3

The unit has an internal quantity meter� It 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�•

In addition the value before the last reset is stored� 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 re-

set 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).•

Consumed quantity monitoring with pulse output4.4

Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→9.3.1).

Consumed quantity monitoring with preset counter4.5

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 meter is reset�

If the quantity x is not reached during t, the meter is automatically 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�

Temperature monitoring4.6

A switching signal for temperature limit values can be provided on output 2� For•

theswitchingfunctions→4.7.

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

onoutput2.Fortheanaloguefunctions→4.8.

Volumetric flow or temperature monitoring / switching4.7

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: [OUx] = [Hno]�•

Hysteresis function / normally closed: [OUx] = [Hnc]�•

First the set point (SPx) is set, then the reset point (rPx) with the requested

difference�

Window function / normally open: [OUx] = [Fno]�•

Window function / 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�

HY = hysteresis; FE = window; examples for volumetric flow monitoring

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�

Volumetric flow or temperature monitoring / analogue function4.8

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�

Current output 4 �� 20 mA (example volumetric flow monitoring)

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�

Customer-specific calibration (CGA)4.9

The customer-specific calibration allows changing the gradient of the curve of

measured values� It influences the display and the outputs�
