Operation 5.4 Displays at operating level 5.4.1 Display line 1 The value shown on display line 1 can be determined by configuration Dis1. This configuration is adjustable only via BlueControl®. The following values can be displayed: – process value (default) – limit value LC The display value, which is also called process value, is the value resulting from function 1. Normally, this is input value 1. 5.4.

Functions . 6 Functions The signal data flow of temperature monitor TB 45 is shown in the following diagram: 6.1 Limiting functions TB 45 can be configured for various functions: • • as a temperature monitor as a limit signaller 6.1.1 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.
Functions 6.2 Linearization The input values of input INP1 or INP2 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 filling curve, are possible. The “ Lin” table is always accessed, when at INP1 or INP2 with sensortype S.TYP= 18: “special thermocouple” or with linearization S.Lin= 1: “special linearization” is selected .
Functions g 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. phys. quantity OuH.x phys. quantity mA / V OuL.x InL.x InH.x mA/V Example for mA/V g Parameters InL, OuL, InH and OuH are visible only with ConF / InP / Corr = 3 selected. Parameters InL and InH determine the input range.
Functions a 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. resetting the input scaling, the settings for + For correspond. InL and OuL as well as InH and OuH must 6.3.1 Input error 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.
Functions 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. a 6.5 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.
Functions g With O2 measurement, specification if parameters related to the measured value should be output in ppm or % is required. This is done centrally during configuration. othrr O2 g 0 1 unit: ppm unit: % Whether the temperature of the non-heated l probe is entered in °C, °F or K can be selected during configuration.
Functions Each of the 2 pre-alarms Lim.2 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which can be switched off individually (parameter = “OFF”). The switching difference HYS.x of each limit value is adjustable. Measured value monitoring For measured value monitoring, the following rules are applicable: Mode of action with absolute alarm (Ex. Lim.1) L.1 = OFF -1999 9999 H.1 Display range H.1 HYS.1 Limit value 1 Outputs LED rot / red H.1 = OFF Display range -1999 9999 L.1 L.1 HYS.
Functions 6.6.1 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 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.
Functions phys. size Out.1 mA / V phys. size Out.0 0/4mA 0/2V Parameter O.Src defines the signal source of the output value. Example: O.Src = 3 20mA 10V signal source for Out.3 is the process value 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.3 for 0/4mA or 0/2V Out.1 = -1999...9999 scaling Out.
Functions 6.7.3 Transmitter supply (optional) With setting O.typ = 5, two-wire transmitter supply is possible via output OUT3. In this case, the analog output of the unit is not available.
Functions 6.8 Maintenance manager / error list In case of one or several errors, the error list is always displayed at the beginning of the extended operating level . A current input in the error list (alarm or error) is always indicated by display of letter E . Description blinks on off ûC üüää 1 2 TB E For display of the error list, press key ô once. E- display element 450.
Functions g 6.9 When an alarm is still pending, i.e. unless the error cause was removed (E display blinks), latched alarms cannot be acknowledged and reset. Reset to default In case of faulty configuration, the device can be reset to the default manufacturers condition. 1 + Power on 1 For this, the operator must keep the keys FAC increment and decrement pressed during power-on. torY 2 Then, press key increment to select YES.
