3.3.4 O2measurement

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 tempera ture 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. When using non-heated l probes, ho wever, the displayed values can be accurate only for a narrow temperature band.

Operation

Unless the probe temperature is known, we recommend using our KS90-1 Oxygen (temperature measurement via a second input).

Configuration: Adjust O

measurement in function 1:

Func r Fnc.1 3 O2 measurement

Display: The displayed value is always a % value. As it is mostly necessary to cover a wide measuring range, we recommend adjusting a high number of digits behind the decimal point during configuration, whereby loss of high values is prevented due to floating decimal point display (0,0001 (1 ppm) to 99999 is possible) .

Specify the number of digits behind the decimal point below othr :

0 0 digits behind the decimal point 1 1 digit behind the decimal point

3.3.6 Alarm handling

Operation

Max. three alarms can be configured and assigned to the individual outputs. Ge nerally, 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 li mit 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.

Operation

The variable to be monitored can be selected seperately for each alarm via configuration The following variables can be monitored:

process value

control deviation xw (process value - set-point)

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.

Set-point

Correcting variable y (controller output signal)

If measured value monitoring + alarm status storage is chosen ( ConF / Lim / Fnc.x=2), the alarm relay remains switched on until the alarm is resetted in the error list ( Lim 1..3 = 1) or via interface.

3.4 Maintenance manager / Error list

In case of one or several errors, the extended operating level always starts with the error list. A current entry into the error list (alarm or error) is displayed by the Err LED in the display. For displaying the error list, pressing 1x Ù is necessary. (with configuration as a controller, press 2x Ù).

4.2 Control parameters

The range of different processes to be controlled is very wide, from very fast pressure control to very slow thermal processes such as control of a blast furnace. As the controller behaviour has to be different with each of these processes, the control parameters must be adjusted for the relevant process individually. Adjust ment can be done either manually or by the controller itself.

Digital 280-1 Operation 17

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 wit hout 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 )

The operator can start self-tuning at any time. For this, keys Ù and È must be pressed simultane ously. The AdA LED starts blinking. The controller outputs 0% or Y.Lo, waits until the process is at rest and starts self-tuning (AdA LED lit permanently).

The self-tuning attempt is started when the following prerequisite is met:

The difference between process value i set-point must be ³ 10% of the

set-point range ( SP.Hi - SP.LO) (with inverse action: process value smaller than set-point, with direct action: process value higher than set-point).

After successful self-tuning, the AdA-LED is off and the controller continues operating with the new control parameters.

ADA FUNC ERR

4.3.2 Self-tuning cancellation

By the operator:

Self-tuning can always be cancelled by the operator. For this, press Ù and È key simultaneously. The controller continues operating with the old parameters.

By the controller:

If the Err LED starts blinking whilst self-tuning is running, successful self-tuning is prevented due to the control conditions. In this case, self-tuning was cancelled by the controller. Dependent of control type, the output status is:

3-pnt. stepping controller:

actuator is closed (0% output) 2-pnt./ 3-pnt./ continuous controller:

If self-tuning was started from the automatic mode, the controller output is 0%. With self-tuning started from manual mode, the controller output is Y2.

Acknowledgement procedures in case of unsuccessful self-tuning

1. Press keys Ù and È simultaneously:

The controller continues controlling using the old parameters The Err LED continues blinking, until the self-tuning error was acknowledged in the error list.

2. Press key Ù :

Display of error list at extended operating level. After acknowledgement of the error message, the controller continues control using the old parameters.

4.4 Manual tuning

The optimization aid should be used with units on which the control parameters shall be set without self-tuning. For this, the response of process variable x after a step change of correcting variable y can be used. Frequently, plotting the complete response curve (0 to 100%) is not possible, because the process must be kept within defined limits.

BlueControl - the engineering tool for the BluePortâcontroller series

Three engineering tools with different functionality facilitating Dig 280-1 confi guration and parameter setting are available (see chapter 8 : Accessory equipment with ordering information). In addition to configuration and parameter setting, the engineering tools are used for data acquisition and offer long-term storage and print functions. The engineering tools are connected to Dig 280-1 via the front-panel interface "BluePort

" by means of PC (Windows 95 / 98 / NT) and a PC adaptor. Description BlueControl: see chapter 8: BlueControl (page 40)

6.3 Input scaling

When using current or voltage signals as input variables for InP.1 or InP.2, scaling of input and display values at parameter setting level is required. Specifi cation of the input value for lower and higher scaling point is in the relevant elec trical unit (mA / V).

phys.

6.3.1 Input Inp

Parameters InL.1 , OuL.1, InH.1 and OuH.1 are only visible if ConF / InP.1 / Corr = 3 is chosen.

The parameters InL and InH determine the input range Example mA: InL= 4 and InH 0 20 means, the measurement is from 4 to 20 mA.

For using the predetermined scaling with thermocouple and resistance thermometer (Pt100), the settings for InL.1 and OuL.1 and for InH.1 and

OuH.1 must have the same value.

The unit is intended exclusively for use as a measurement and control instrument in technical installations.

Warning

If the unit is damaged to an extent that safe operation seems impossible, the unit must not be taken into operation.

ELECTRICAL CONNECTIONS

The electrical wiring must conform to local standards (e.g. VDE 0100). The input measurement and control leads must be kept separate from signal and power supply leads. In the installation of the controller a switch or a circuit-breaker must be used and signified. The switch or circuit-breaker must be installed near by the controller and the user must have easy access to the controller.

COMMISSIONING

Before instrument switch-on, check that the following information is taken into account:

Ensure that the supply voltage corresponds to the specifications on the type

label. All covers required for contact protection must be fitted.

If the controller is connected with other units in the same signal loop, check

that the equipment in the output circuit is not affected before switch-on. If necessary, suitable protective measures must be taken. The unit may be operated only in installed condition.

Before and during operation, the temperature restrictions specified for

controller operation must be met.

SHUT-DOWN

For taking the unit out of operation, disconnect it from all voltage sources and protect it against accidental operation. If the controller is connected with other equipment in the same signal loop, check that other equipment in the output circuit is not affected before switch-off. If ne cessary, suitable protective measures must be taken.
