Functions . 6 Functions The signal data flow of transmitter SG 45 is shown in the following diagram: 6.1 Measuring input INP Measuring range 0.5 mV/V (5 mV) 1 mV/V (10 mV) 2 mV/V (20 mV) 4 mV/V (40 mV) Configuration S.
Functions 6.2 Input scaling Scaling of input values is possible. This correction influences the measured value after an eventually executed linearization. g 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 InH.x mA/V InL.x Example for % g The Parameters InL, OuL, InH and OuH are always visible. These are created during calibration. Parameters InL and InH determine the input range.
Functions 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.
Functions 6.4 Filter A 1st order mathematical filter with adjustable time constant and bandwidth is built in. x Output Input b.F t 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.
Functions 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.
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: 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.
Functions 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 g The signal to be monitored can be selected separately for each alarm in the configuration.
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). Behaviour with signal change (Ex. Lim1) L.1 = OFF x {x {t >H.1 {x {t >H.1 t [min] Lim.
Functions g With measurement value or signal change with latch selected ( ConF / Lim / Fnc.x = 2, 4), the alarm relay remains set, until it was reset in the error list, This alarm can be reset via: di1 or a limit value a key combination or via interface (Lim1 ... Lim3 = 1). For this, reset value 0 must be specified in the error list or via the interface. ( r page 36). H.1 = OFF x {x {t
Functions 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.
Functions 6.12 Analog output configuration 6.12.1 Analog 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. ConF / Out.3: O.tYP = = = = 1 2 3 4 Out.3 Out.3 Out.3 Out.3 0...20mA continuous 4...20mA continuous 0...10V continuous 2...10V continuous phys. size Out.1 mA / V phys. size Out.0 0/4mA 0/2V 20mA 10V Parameter O.Src defines the signal source of the output value. Example: O.
Functions 6.12.2 Analog output forcing By adjusting f.Out = 1 (only via BlueControl Ò), the output can be configured for value input via interface, or by means of an input value at extended operating level (=Forcing). g g SG 45 This setting can be used also for e.g. testing the cables and units connected in the output circuit. This function can also realize a setpoint potentiometer.
Functions 6.13 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 . For display of the error list, press key ô once. 450.
Functions g Latched alarms Lim1/2/3 (E-element displayed) can be acknowledged, i.e. reset via digital alarm di1. For Configuration, see page 41: ConF / LOGI / Err.r g When an alarm is still pending, i.e. unless the error cause was removed ( E display blinks), latched alarms cannot be acknowledged and reset.
Functions 6.15 Resetting to factory setting In case of faulty configuration, the SG 45 can be reset to the default manufacturers condition. 1 1 For this, the operator must keep the keys increment and + Power on switch on power supply FAC decrement pressed during power-on. torY 2 Then, press key increment to select YES. 3 Confirm factory resetting with Enter and the copy FAC procedure is started (display COPY). no 4 Afterwards the device restarts.
