Measuring range Configuration S.tYP

0.5 mV/V (5 mV) 1 mV/V (10 mV) 2 mV/V (20 mV)

4 mV/V (40 mV) 63

Input for bridge circuit (3 possibilities):

Bridge supply + mV input (4-wire)

Bridge supply + mV input + Sense input (for measuring the bridge voltage applied to the sensor) (6-wire):

Bridge supply + mV input + calibration output (for defined change of the bridge resistance): Using a built-in switch, a known resistor is switched in parallel to one of the 4 bridge resistors, configurable via CAL..M.

Automatic 4 or 6-wire detection after start-up

Automatic detection, if the sense signal is connected: This function is active during start-up (after switch-on or re-con figuration). See circuit example on page 9.

Due to 6-wire connection, errors caused by voltage drops on the supply leads are prevented.

SG 45 Measuring input INP 23

6.2 Input scaling

Scaling of input values is possible. This correction influences the measured value after an eventually executed linearization.

Functions

Specification of the input value of the lower and upper scaling point is in units of the relevant physical quantity.

Example for %

The Parameters InL, OuL, InH and OuH are always visible. These are created during calibration.

Parameters InL and InH determine the input range.

Example with %: InL= 4 and InH = 10 means that measuring from 4 to 10 % is required.

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

SG 45 Input scaling 24

6.3 Linearization

The input values of the input can be linearized via a table.

This feature can be used e.g. to realize linearizations to specification for non-linear curves. The “ Lin” table is always used when S.Lin = 1: “Linearization to specification” is set in INPm. The input

signals are filled in in units of the physical quantity (scaling result).

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.

Functions

Required: Condition for the input values is an ascending order.

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

A 1st order mathematical filter with adjustable time constant and bandwidth is built in.

Output

Input

The filter bandwidth b.F1 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 (=forc ing).

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

Tip: The selected unit can be displayed on line 2.

6.7 Set zero

The function is enabled during configuration (Func r Func.1 =1. Due to its effect, the display is reset to zero, when e.g. small rest quantities are still on the scale and cannot be re moved immediately. To prevent excessive use of the zero setting function, the zero offset (page 30) can be provided with an alarm. After cleaning the scale, zero setting must be repeated. Dependent on configuration, the zero setting function can become effective by a pulse on digital input di1, a limit value, by pressing a combination of keys or via an interface signal (LOGI r tArA). See page 41.

6.8 Tare function

Functions

6.10 Integrator function

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:

With a constant input value, the integrator output reaches the specified value after elapse of the adjusted time con stant t.I.

Reset:

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

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)

· 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 (50ms).

6.11 Limit value processing

Max. three limit values can be configured for the outputs. Generally, each one of outputs Out.1... Out.2 can be used for limit value or alarm signalling.

Several signals allocated to an output are linked by a logic OR function.

6.11.1 Input value monitoring

Functions

The signal to be monitored can be selected separately for each alarm in the configuration. The following signals are available:

Process value (display value)

•

Measured value INP

•

Zero adjustment

•

Each of the 3 limit values Lim.1 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which can be switched off individually (parameter = “OFF”). The hysteresis HYS.x of each limit value is adjustable.

Input value monitoring is as shown below:

Functions

Alarm delay

An alarm can become effective with a delay: the alarm output is set only after elapse of the adjusted delay time, provided that the limit value is still exceeded. Shorter alarms than the adjusted delay are ignored.

Example: Alarm delay

Signal change monitoring

Another limit value processing function is signal change monitoring (per minute).

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.

6.11.2 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 acti vated (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 moni toring 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 moni toring timer. Monitoring can be stopped by switching off limit value C.Sch.

A switching cycle counter is allocated to each output. Limit value C.Sch acts on all switching cycle counters.

Adjusting the limit value for the number of switching cycles C.Sch can be done only via BlueControl®.

The current counter state can be displayed in the BlueControl

Scaling of the output range is done via parameters Out.0 and Out.1. The values are specified in units of the physical quantity.

Out.0 = -1999...9999 scaling Out.3for 0/4mA or 0/2V Out.1 = -1999...9999 scaling Out.3for 20mA or 10V

Example: Output of the full input range (0 … 100)

Example: output of a limited input range, e.g. 60.5 … 63.7 °C)

Please, note: the smaller the span, the higher the effect of input variations and resolution.

Using current and voltage output in parallel is possible only in galvanically isolated circuits.

Configuration O.tYP = 2 (4 … 20mA) or 4 (2...10V) means only allocation of the reference value (4 mA or 2V) for scaling of output configuration Out.0. Therefore, output of smaller values is also possible rather than output limiting by reference value 4mA / 2V.

Configuration O.tYP = 0/1 (0/4...20mA) or 2/3 (0/2...10V) determines, which output should be used as a calibrated reference output.

6.12.2 Analog output forcing

By adjusting f.Out = 1 (only via BlueControlÒ), the output can be configured for value input via interface, or by means of an input value at extended operating level (=Forcing).

With pressure sensors, the sensor should be de-pressurized, or pressure setting for span start:

Calibration 1. step: Define span start

Display:

InL.1 = OFF

Calibration 2. step: Define calibration value

InH.1 = OFF Press keys p/q to display the instantaneous measured value. InH.1 = swaps with the

For sensors with integrated calibration resistor an automatic switching of the calibration resistor is done.

For the first calibration SEtit is recommended to configure CAL.M =1,->S.47

(The calibrating resistor is switched off automatically)

Calculation for calibrating resistor (e.g. 80% ) Example:

The calibrating resistor has a range from 0..400

A tare function activated before calibration must be de-activated. Normally, it is not purposeful to keep the old tare condition. If necessary, the tare function can be re-activated. The zero offset is deleted automatically.

The InL.1 and InH.1 values stored during calibration are stored with full resolution.
