As long as the È key is pressed, the maximum value is displayed.
Operation 3.3.2 Tare function When switching on the tare function, the instantaneous measured value is set to zero. In this case, measurement is continued with this offset. By switching off the tare function, the actual measured value is displayed again. measured value effective value è è ADA FUNC ERR è ADA FUNC ERR t ADA FUNC ERR Tare can be activated during configuration (Func r Fnc.1 = 1).
Operation 3.3.4 O2 measurement For measurement, lambda probes (l probes) are used. The electromotive force (in Volt) supplied by the l probes is dependent of the instantaneous oxygen content and of the temperature. Therefore, Digital 280-1 can display accurate measurement results only, provided that the probe temperature is known to the indicator. Enter the temperature in °C in parameter tEmP. When using heated l probes, the probe temperature can be entered directly.
Operation 3.3.5 Extended operating level The content of the extended operating level is determined by means of BlueControl (engineering tool). Parameters which are important or which are used frequently can be copied into the extended operating level. Actuating key Ù switches to the first value of the extended operating level (may be Digital 280-1 preceded by error list or set-point). The selected parameters can be changed by pressing keys Ì and È.
Operation 3.3.6 Alarm handling Max. three alarms can be configured and assigned to the individual outputs. Generally, outputs OuT.1... OuT.3 can be used each for alarm signalling. If more than one signal is linked to one output the signals are OR linked. 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”). Switching difference HYS.x of each limit value is adjustable. Operaing principle absolut alarm L.1 = OFF InL.
Operation g g The variable to be monitored can be selected seperately for each alarm via configuration The following variables can be monitored: w process value w control deviation xw (process value - set-point) w control deviation xw + suppression after start-up or set-point change As there is automatically a control deviation after starting up and after set-point changes, however, the alarm is suppressed, until the signal was within the limits once.
Controller 4 Controller In addition to the simple indicator function, Digital 280-1 can be used also as a signaller or an on/off controller, as a two point or a continuous controller. Prerequisite: Digital 280-1 is fitted with option “with outputs” and is configured for the controller function. Configuration: Function 2 provides selection between indicator and controller: Func r Fnc.2 Controller 4.
Controller 4.3 Self-tuning After starting by the operator, the controller makes a self-tuning attempt. The controller uses the process characteristics for quick line-out to the set-point without overshoot. g g Self-tuning start can be locked via BlueControl (engineering tool) ( P.Loc). ti and td are taken into account only, if they were ¹ OFF previously. 4.3.1 Self-tuning start ( Ù + È ) Digital 280-1 OUT1 The operator can start self-tuning at any time.

Controller Start: heating power switched off The controller waits 1,5 minutes (1). Heating power Y is switched on (2). At the reversal point, the self-tuning attempt is finished and control to the set-point is using the new parameters. X W t 100% Y 0% start r 1 Start: at set-point Heating power Y is switched off (1). If the change of process value X was constant during one minute and the control deviation is > 10% of SP.Hi SP.LO (2), the power is switched on (3).
Controller The control parameters can be determined from the values calculated for delay time Tu , maximum rate of increase vmax, control range Xh and characteristic K according to the formulas given below. Increase Xp, if line-out to the set-point oscillates.
