as a temperature monitor

•

as a limit signaller

•

6.1.1 Temperature limiter

If selected, a temperature limiter fun ction monitors the process value. When exceeding the (configurable) low or high limit value LC, the output relay LC is opened and disabled.

Releasing is possible only, when

–

the process valueis below the adjusted high limit value LC (minus any adjusted hysteresis) again with setting ”Temperature limiter max. (latch)”, or when the process value is above low limit value LC (plus any adjusted hysteresis) again with setting “Temperature limiter min. (latch)”.

–

When display element TB is lit, a temperature limiter function is selected.

Please, note that the adjusted filter time t.F1 can increase the response time for the process value. The DIN-tested response times were tested with t.F1 = 0,5 s.

: Configuration / Others / IRES = 1).

TB 45 Limiting functions 21

Limit values Lim.2, Lim.3 can be used as pre-alarms for (optional) output on OUT.2, OUT.3.

Functions

6.1.2 Temperature monitor

The selected temperature monitor function monitors the process value. When the process value is above the adjusted high limit value LC or below the adjusted low limit value LC (configurable), output relay LC is opened and disabled.

Release is automatic, when

the process value is below the adjusted high limit value LC (minus any adjusted hysteresis) again with setting

–

”Temperature monitor max.”, or when the process value is above the adjusted low limit value LC (plus any adjusted hysteresis) again with setting “Temperature monitor min.”.

Please, note that the adjusted filter time t.F1 can increase the response time for the process value. The DIN-tested response times were tested with t.F1 = 0,5 s.

Limit values Lim.2, Lim.3 can be used as pre-alarms for (optional) output on OUT.2, OUT.3.

6.1.3 Limit signaller

A selected limit signalling function monitors the process value. When exceeding the adjusted limit values L.1 / H.1 , output relay LC is opened (see also chapter Limit values!) Limit values Lim.2, Lim.3 can be used as pre-alarms for (optional) output on Out.2, Out.3.

6.2 Linearization

The input values of input INP1 can be linearized via a table (dependent from adjusted sensor type S.tYP). By means of tables, e.g. special linearizations for thermocouples or other non-linear input signals, e.g. a container fill-

ing curve, are possible. The “ Lin” table is always accessed, when at INP1 with sensortype S.TYP= 18: “special thermocouple” or with

linearization S.Lin= 1: “special linearization” is selected .

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 µV, 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 16 segment points. Each segment point comprises an input (In.1 … In.16) and an output (Ou.1 … Ou.16). 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.16.

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

6.3 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 shouldbe 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.

Example for mA/V

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

Parameters InL and InH determine the input range.

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

Functions

INP2

INP1

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.

6.3.1 Input error detection

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

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

Example 1: In.L = 4 mA, In.H =20mA

Fail response value ≤ 2mA

Example 2: In.L =2V,In.H =6V

Fail response value ≤ 1,5 V

6.3.2 Two-wire measurement

Normally, resistance and resistance thermometer measurement is in three-wire connection, whereby the resistance of all leads is equal. With two-wire measurement, the lead resistance is included directly as a falsification in the measurement result. How ever, 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 mea sured value via the scaling.

6.3.3 Connection Thermocouple

If the device is used as a teperature limiter, a double thermocouple must be connected. For measurements in the area of ambient temperature (0mV) the plausibility is ensured by the control of the 2nd thermocouple. Outside of this range there is no check of the 2nd thermocouple.

If the device is used as a teperature monitor or limit signaller, no double thermocouple should be connected. There is no plausibility check. (See connecting diagram Chapter 4.1)

6.4 Filter

A first order mathematic filter can be used for the input values. The time constant is adjustable. This low-pass filter is used for suppression of process-dependent interference on the input leads. The higher the value, the better the filter effect, but the longer the input signal delay.

Functions

Please, note that the adjusted filter time t.F1 can increase the response time for the process value. The DIN-tested response times were tested with t.F1 = 0,5 s.

monitoring is possible via the limit values.

6.5 Limit value processing

The main alarm acts on the process value and is firmly allocated to relay output LC the output action of which is set to inverse continuously. With the temperature limiter/monitor function, the limit value is adjusted by means of parameter LC. With the limit signaller function, the limit value is adjusted via L.1 / H.1. The limit value switching difference HYS.1 is adjustable.

Max. two further limit values can be configured as pre-alarms and allocated to the individual outputs Out.2....

Out.3. Several signals assigned to an output are logically ORed.

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

6.5.1 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).

Functions

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®.

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

Out.0 = -1999...9999 scaling Out.3

for 0/4mA or 0/2V

Out.1 = -1999...9999 scaling Out.3

for 20mA or 10V

Example: output of the full input range of thermocouple type J (-100 … 1200 °C)

Out.0 = -100 Out.1 = 1200

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

Out.0 = 60.5 Out.1 = 63.7

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.
