4.5 Configuration example

For a successful parameter input, see the following example of a flow measurement, with alarm monitoring.

↑ Situation ↑ Adjustment

• Sensor range:

10g/min ... 100g/min

• Alarm by reaching a throughput rate of

50 kg

• creep suppression:

12g/min

Procedure:

1] Measure range:

2] Bargraph:

3] Limits:

4] creep suppression:

5] Alarm monitoring mode:

010,0 g/min ... 100,0 g/min for 4 ... 20 mA

010,0 g/min ... 100,0g/min

Limit relates to the sum (Limit):

50 kg

012,0 g/min circuit-opening connection

CodE1

One touch on the enter-button quits the normal state and starts

the input menu.

The menu interrogates for code 1.

The default code 1 is [0001].

Enter the right code word using the arrow buttons.

Finally hit the enter-button.

Scaling display and bargraph:

Join the scale menu pressing the enter-button.

First set the position of the decimal point. The position of the decimal point will be used for each parameter, like display, bargraph and limits.

Set the decimal position after the third position (count from left side), because we will enter [1000] (100 g/min) for the high scale point afterwards.

Choose the enter-button to edit the decimalpoint position and press the right-button for three times.

Confirm with the enter-button.

Now the [scale point low] view appears.

Edit by pressing the enter-button and enter the lower scale

point

[0100] (10g/min) as follows:

Press the right-button for two times to select the second figure.

SCA H

Confirm the lower scale point pressing the enter-button. Now the...

... item appears.

Repeat the input procedure for the upper scale point like the lower scale point. Enter [1000] (100 g/min) for the upper scale point.

(Confirm by hitting enter-button)

Enter the upper scale point correct figured ‘as big as possible’

(the first figures should not be ‘0’)

In this case you get the maximum precision of the totalizer.

bAr L bAr H

Now scale the bargraph. Hit the enter-button.

Enter [0100] (10 g/min) for the lower bargraph scale point.

Confirm by hitting the enter-button

Enter [1000] (100g/min) for the upper bargraph scale point.

Hitting enter-button accepts and quits the scale menu.

;

Prescale factor and creep suppression

Start total menu by pressing enter-button.

I-FAC

Press enter-button a further time to edit the prescale factor.

Enter the value [ 6E4] (60 000) using the arrow-buttons. To

define the correct prescale factor see paragraph 4.4.

Confirm by hitting the enter-button.

StArt

LIS Y

Press now the enter-button to edit the creep suppression value.

Use the arrow-buttons to enter [0120] (12 g/min).

(Confirm by hitting the enter-button.)

Finally, let the alarm monitoring refer to the sum. Select [LIS_Y] using the arrow-buttons and confirm with the enter-button.

PUL

Totalizer with external reset and current flow signal option

(D122.Z.x.3) have additional the option to configure the digital output.

Pass this menu item using the right-button, to keep the default setting: pulse output = no (=false)

;

Limits, Hysteresis and time delay

LI

LI H

Start the limit menu by pressing the enter-button.

The device skips the input of the lower limit, because the limit refers to the sum.

Con H

The upper limit input appears.

After hitting the enter-button enter the limit [0050.0] (50 kg) using the arrow-buttons.

Confirm by hitting the enter-button.

The hysteresis and time delay are also skipped.

Now choose the circuit-opening connection [nc---] (normaly closed) using the up-button and confirm by pressing enter-button.

We pass simply the following menu items (manipulate code words and calibrate) using the right-button.

End

Finally quit the scale menu hitting the enter-button.

The totalizer is back in normal state. The changes are immediately active and will still be active after power off

(disconnecting the totalizer).
