Functions

The signal data flow of transmitter CI 45 is shown in the following diagram:

6.1 Linearization

The input values of input INP1 or INP2 can be linearized via a table.

By means of tables, e.g. special linearizations for thermocouples or other non-linear input signals, e.g. a container filling curve, are possible.

Table “ Lin” is always used with sensor type S.TYP= 18: "Special thermocouple" in INP1 or INP2, or if linearization S.Lin = 1: “Special linearization” are adjusted.

The input signals must be specified in mV, V, mA, % or Ohm dependent on input type.

For special thermocouples (S.tYP = 18), specify the input values in mV, and the output values in the temperature

unit adjusted in U.LinT . For special resistance thermometer (KTY 11-6) (S.tYP = 23), specify the input values in Ohm, and the output values

in the temperature unit adjusted in U.LinT.

Non-linear signals can be linearized using up to 32 segment points. Each segment point comprises an input (In.1 … In.32) and an output (Ou.1 … Ou.32). These segment points are interconnected automatically by straight lines. The straight line between the first two segment points is extended downwards and the straight line between the two highest segment points is extended upwards, i.e. a defined output value for each input value is provided.

With an In.x value switched to OFF, all further segments are switched off.

Condition for the input values is an ascending order.

In.1 < In.2 < ...< In.32.

For linearization of special thermocouples, the ambient temperature range should be defined exactly, becauseit is used to derive the internal temperature compensation.

The same linearization table is used for input 1 and input 2.

6.2 Input scaling

Scaling of input values is possible. After any linearization, measurement value correction is according to the offset or two-point method.

When using current or voltage signals as input variables for InP.x, the input and display values should be scaled at the parameter level. Specification of the input value of the lower and upper scaling point is in units of the relevant physical quantity.

20 Input scaling UNIFLEX CI 45

Parameters InL, OuL, InH and OuH are visible only with ConF / InP / Corr = 3 selected.

Parameters InL and InH determine the input range.

Example with mA: InL= 4 and InH = 20 means that measuring from 4 to 20 mA is required (life zero setting).

Functions

For using the pre-defined scaling with thermocouples and resistance thermometers (Pt100), the settings for InL and OuL as well as for InH and OuH must correspond with each other.

For resetting the input scaling, the settings for InL and OuL as well as InH and OuH must correspond.

6.2.1 Input fail detection

For life zero detection of connected input signals, variable adjustment of the response value for FAIL detection is possible according to formula:

Fail response value £ In.L - 0,125 * (In.H - In.L)

Example 1: In.L = 4 mA, In.H = 20 mA Fail response value £ 2mA

Example 2: In.L =2V,In.H = 6 V Fail response value £ 1,5 V

6.2.2 Two-wire measurement

Normally, resistance and resistance thermometer measurement is in three-wire connection, whereby the resistance of all leads is equal. Measurement in four-wire connection is also possible for input I. With this method, the lead resistance is determined by means of reference measurement. With two-wire measurement, the lead resistance is included directly as a falsification in the measurement result. However, determination of the lead resistances by means of is possible.

Besides the connection of the both leads of the RTD / R sensor the 3rd connector has to be short-circuited.

Procedure with Pt100, Pt1000

Connect a Pt100 simulator or a resistance decade instead of the sensor at the test point so that the lead resistance is included and calibrate the values by means of 2-point correction.

By means of measurement value correction the resulting temperature value will be corrected, but not the resistance input value. In this case the linearization error can increase.

Procedure with resistance measurement

Measure the lead resistance with an ohmmeter and subtract it from the measured value via the scaling.

6.2.3 Scaling with potentiometer measurement

With potentiometer measurement (S.tYP = 50 … 53), a display value in 0% (lower stop value) to 100 % (upper stop value) is normally expected.

For this, 2-point calibration at calibrating level (rp. 49) Is necessary.

6.3 Temperature compensation, measured via INP2 (optional)

With thermocouple measurement via INP1, the required temperature compensation is possible by internal measurement of the compensation temperature via an external reference (external TC) or by measurement via INP2.

With TC measurement via INP2, the following settings must be done:

setting in the function for: ConF / Func / Fnc.1 = 10

•

input 1 for thermocouple input : ConF / InP.1 / S.tYP = 0 … 18

•

Switch on input 2 for measurement : ConF / InP.2 / I.Fnc = 1

•

Select suitable sensor element for input 2: ConF / InP.2 / S.tYP

•

Example:

For saving compensating cable, or unless suitable cables for special thermocouples are available, the

–

termperature at the thermocouple connecting terminal must be measured exactly by means of a resistance thermometer (e.g. Pt100).

Unless input 2 is enabled for measurement, the unit generates error E.3 (configuration error).

Please, note that there may be increased errors or even polarity errors with a thermocouple measuring range starting only at 0°C (32°F), when the outside temperature is low.

The filter bandwidth b.Fx is the adjustable tolerance around the measured value within which the filter is active. Measurement value changes in excess of the adjusted bandwidth are not filtered.

6.5 Substitue value for inputs

If a substitute value for an input is activated, this value is used for further calculation with a sensor fault, independent of the selected input function. The selected controller output reaction on sensor fault, configuration FAIL, is omitted.

With factory setting, the substitute value is switched off.

Before activation of a substitute value In.F, the effect on the control loop must be considered.

6.6 Input forcing

Setting f.AIx = 1 (only via BlueControl®) can be used for configuring the input for value entry via the interface (=forcing).

Please, check the effect on the control loop in case of failure of input value / communication and exceeded measuring range.

6.7 O2 measurement (optional)

This function is available only on instrument versions with INP2 . Lambda probes (l probes) are used as input signals. The electromotive force (in volt) delivered by lambda probes is

dependent on the instantaneous oxygen content and on the temperature. Therefore, transmitter CI 45 can only display accurate measurement results, if the probe temperature is known.

Distinction of heated and non-heated lambda probes is made. Signals from both types can be handled by CI 45.

Heated lambda probes

Heated l probes are fitted with a controlled heating, which ensures a continuous temperature. This temperature must be specified in parameter Probe temperature in transmitter CI 45. Parameters ® Functions ® Pro be temperature tEmP ® ...°C (/°F/K - dependent on configuration)

Non-heated lambda probes

When the probe is always operated at a fixed, known temperature, the procedure is as with a heated probe.

UNIFLEX CI 45 Filter 23

Functions - preliminary -

A non-heated l probe is used, if the temperature is not constant. In this case, the temperature in addition to the probe mV value must be measured. For this purpose, any temperature measurement with analog input INP2 can be used. During function selection, input INP2 must be set for measurement (CONF/InP.2/I.Fnc=1).

Configuration: O

-measurement must be adjusted in function 1 :

Func r Fnc.1 7

Connection

Connect the input for the lambda probe to INP1 . Use terminals I and 2. If necessary, temperature measurement is connected to INP2.

Input 1 is used to adjust one of the high-impedance voltage inputs as sensor type:

Inp.1r S.tYP

These high-impedance inputs are without break monitoring. If necessary, input signal monitoring is possible via the limit values.

Further recommendations for adjustment:

Simulation

For simulation of the counter input in the BlueControl®engineering tool, a counter pulse can be simulated using the checkbox of digital input di1 or via input window “Freq”. The input value must be specified in kHz.

6.9 Frequency input (optional)

Digital input di1 can be configured as a frequency input (dependent on ordering code). The frequency is a function of the number of pulses counted during the gate time.

The display value is updated at the earliest after elapse of the gate time.

The input signal can be totalized by means of a selectable integrator (ConF \ Func \ Fnc.3 = 3).

Function:

Integrator with adjustable time constant (PArA \ Func \ t.I) [specified in minutes] and adjustable input offset (PArA \ Func \ P.I)

Formula:

y(t) = y(t-Tr) + Tr/t * (x +P.I)

y(t) = integrator output y(t-Tr) = integrator output of the last cycle Tr = cycle time (100ms INP1, 140ms INP1 + INP2) t = time constant x = integrator input P.I = input offset (zero offset)

With a constant input value, the integrator output reaches the specified value after elapse of the adjusted time

constant t.I.

Reset:

Dependent on selection (ConF\Logi\rES.I), the integrator can be reset via:

Functions

Digital input di1

Key combination Enter + increment key

(keep the Enter key pressed and actuate the increment key) Limit values Limit1 to Limit3

Example 1:

A flow in m3/h is measured. The integrator should measure the overall flow quantity. The measured flow is related to time unit hours, i.e. time constant t.I = 1 hour = 60 min must be used. Parameter P.I can be used for zero correction.

Example 2: pulse output

The integrator is activated. The resulting process value is monitored using a limit value (without memory) , e.g. Lim1. Lim.1 is defined as integrator reset function. Limit value Lim.1 is output e.g. on ouput 1 (OUT.1). When exceeding limit value Lim1, there is a signal change at OUT1 during a period (100ms INP1, 140ms INP1 + INP2).

With measurement value or signal change with latch selected ( ConF / Lim / Fnc.x=2, 4), the alarm relay remains set, until the alarm was reset in the error list, via di1 or via the interface (Lim1 ... Lim3 = 1). For this, reset value 0 must be specified in the error list or via the interface.

After power on or an engineering download an used input filter has an effect on the gradient of the input signal. Therefore a valid alarm monitoring can only be processed after a certain rise up time. This time depends on the value of the filter time constant t.F. For t.F = 0 the monitoring results are valid immediately.

6.14.2 Monitoring the number of operating hours and switching cycles

Operating hours

The number of operating hours can be monitored. When reaching or exceeding the adjusted value, signal InF.1 is activated (in the error list and via an output, if configured).

The monitoring timer starts when setting limit value C.Std. Reset of signal InF.1 in the error list will start a new monitoring timer. Monitoring can be stopped by switching off limit value C.Std.

Adjusting the limit value for operating hours C.Std can be done only via BlueControl®.

The current counter state can be displayed in the BlueControl

The number of operating hours is saved once per hour. Intermediate values are lost when switching off.

Number of switching cycles

The output number of switching cycles can be monitored. When reaching or exceeding the adjusted limit value, signal InF.2 is activated (in the error list and via an output, if configured).

The monitoring timer starts when setting limit value C.Sch. Reset of signal InF.2 in the error list will start a new monitoring timer. Monitoring can be stopped by switching off limit value C.Sch.

Calibrating level

Adaptation of the measurement value is possible in the calibrating menu ( CAL).

Measured value correction ( CAL) is accessible only, if ConF / InP/ Corr = 1 or 2 was selected.

Two methods are possible :

offset correction

•

2-point correction

•

Values InL.x and InH.x are displayed with one digit behind the decimal point. However, the full resolution is used as a reference for calculating the correction.

The easiest way to delete the corrective values is by switching off the measured value correction

Corr = 0 or by setting the scaling parameters to a linear curve.

Values InL.x and InH.x indicate the actual measurement value. Output values OuL.x and

OuH.x start with the previously adjusted value.
