Functions . 6 Functions The signal data flow of temperature limiter TB 45 is shown in the following diagram: Display INP Linearization Scaling/ Correction LC Func 1 INP1 Min* Max* Limit value OUT2 OUT3* di1 OUT3* * Option 6.1 Scaling (analog) Limiting functions TB 45 can be configured for various functions: • • • as a temperature limiter as a temperature monitor as a limit signaller 6.1.1 Temperature limiter If selected, a temperature limiter fun ction monitors the process value.
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.
Functions Ou.16 . . . . . . Ou.1 In.1 g 6.3 In.16 The linearization table is used for input 1 Input scaling Scaling of input values is possible. After any linearization, measurement value correction is according to the offset or two-point method. 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.
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 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 6.5.1 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 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 6.6 Analog output configuration 6.6.1 Analog output (optional) An analog output is available as a display output. The two output signals (current and voltage) are available simultaneously. Adjust ConF / Out.3 / O.tYP to select the output type which should be calibrated.

Functions 6.6.2 Logic output (optional) Analog output OUT3 can be used also as a logic output (O.typ = 0). This output can be used e.g. for pre-alarms. 6.6.3 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.
