The display changes depending on how long you touch the "Display" button.

Each display can be identified with the symbols in the identification window.

• If you touch the "Display" button for less than 1 second, the display switches temporarily to the flow display. This is indicated by the symbol "u“ under the lower left digit position. After 10 seconds, the display returns automatically to the main meter.

• If you touch the "Display" button between 1 to 2 seconds you move to the K factor and then to the display test. Then you return automatically to the main meter.

• If the switching magnet touches "Display" for more than 2 seconds, the return flow quantity meter, the malfunction quantity meter and the sum meter are shown. The display sequence ends with the display of the main meter.

U Touching the "Reset" button resets the main meter immediately and adds the number to the sum

meter. At the same time the return flow and malfunction quantity meters are reset to zero.

This operation type is identified with "Flow Display Permanent" in the configuration software.

The user can decide if he wants the display to continuously show the volume of the main meter or the flow. By using the switching magnet you can switch from the main meter to the other functions.

The display changes depending on how long you touch the "Display" button.

Each display can be identified with the symbols in the identification window.

• If, starting from the main meter, you touch the "Display" button for less than 1 second, the display switches to the flow display, until you touch the button again. This is indicated by the symbol "u“ under the lower left digit position. There is no automatic return to the main meter.

• If, starting from the main meter, you touch the "Display" button between 1 to 2 seconds you move to the K factor and then to the display test. Then there is an automatic switching to the flow display. To return to the main meter, touch the "Display" button with the switching magnet for less than 1 second.

• If, in the main meter display, the switching magnet touches the "Display" button for more than 2 seconds, the return flow quantity meter, the malfunction quantity meter and the sum meter are shown. The display sequence ends with the display of the flow.

U Touching the "Reset" button resets the main meter immediately and adds the number to the sum

Table: Return Identification

Function

Main meter decrements during return

Return meter is decremented after return

Type of Return Identification Description

OFF OFF Malfunction: When the meter runs backwards, the return quantity is interpreted as a malfunction quantity. The return and the malfunction quantity meters are incremented.

The warning message can only be deleted with the switching magnet or through the serial interface with the SensorPort program. During the execution of the reset-function the sum counter increases the amount of the main counter. The return quantity goes lost.

ON OFF Normal Operation: When the meter runs backwards, the return meter is incremented and the main meter is decremented. There is no effect on the malfunction quantity meter. When the meter runs forwards after this, the warning message is deleted automatically. During execution of the reset-function the sum counter is increased by the total of the main and return counters.

OFF ON Malfunction: When the meter runs backwards, the return amount is interpreted as a malfunction quantity. The return and malfunction quantity meters are incremented. The warning message can only be deleted with the switching magnet or through the serial interface with the SensorPort program. If the warning “E13” is not deleted during following counter advance the return counter is decremented and the main counter stops until the return counter achieves “0” During execution of the reset-function the sum counter is increased by the difference of the main and return counters.

ON ON Normal Operation: When the meter runs backwards, there is no effect on all meters.

When afterwards the meter runs forwards, the warning message is deleted automatically. During the execution of the reset-function the sum counter is increased by the amount of the main counter.

The remaining functions correspond to operation type 2.

return identification (operation type 3, only for model AG5x...); - creeping motion amount suppression; when the function "Reaction to Alarm and Warning" is activated.

K Factor: Calibration factor in Pulses/L.

Flow attenuation factor: The attenuation factor in seconds affects the display information and the output.

Flow decimal points: Number of digits after the decimal point in the flow display

Electronic Counter


Quantity decimal points: The number of digits after the decimal point in the quantity displays

The maximum number of digits after the decimal points is dependent on the K factor setting:

"3" if K Factor > 100

"2" if 10 < K Factor ≤ 100"

"1" if 1< K Factor ≤ 10

"0" if K Factor ≤ 1

The following manufacturer's constants may only be changed by the customer upon instructions from Bopp & Reuther. They serve for a later extension for the local Bureau of Standards.

IF5V: Standard value = 5

IF5V-min: Standard value = 2

K15: Standard value = 15,000

Actual: Standard value = 8

Actual min: Standard value = 2

IR-max: Standard value = 15

IR-min: Standard value = 2

f-max: Standard value = 1000

f-min: Standard value = 1

ZP: Standard value = 2000

7.3.1.3 Record Card "Operation Type"

Flow display: Permanent (operation type 2 or 3):The user can set the display with the switching magnet to continuously show the main meter or flow. Disappears after 10 sec. (operation type 1):The instrument shows the main meter continuously. A display of the flow quantity is possible for a limited time.

Suppression of creeping motion quantities: Active: If the flow value is in the range of Q < 0.3 * Qmin, the electronic meter shows this

with the display of the malfunction meter (when showing volume), or the flow, which blinks every second. The flow is counted by the malfunction quantity meter. Qmin[ℓ/min.] = f-min[Hz] / K Factor[Pulses/ℓ] * 60

Main meter is decremented during return: See 7.2.3

Return meter is decremented during return: See 7.2.3

Identification of time errors: Active: Identification of errors E.08 (battery replacement required) and E.18 (calibrating cycle required), if the function "Reaction to Alarm and Warning" is activated.

Forwards and return identification: Active: The return identification (operation type 3) is possible. Only for model AG5x....

Electronic Counter


Output behavior: Only for models with NAMUR power supply.

Warning: Depending on the position of the slide switch, output 3 (terminals 5+6) or output 1 (terminals 1+2) is set as warning output. The identification of warning messages is possible, if the function "Reaction to Alarm and Warning" is activated. Scaled pulses: Depending on the position of the slide switch, output 3 or output 1 is set to scaled pulses.

Reaction to alarm and warning: Active: Alarm and warning messages are shown on the display. The corresponding alarm or warning output is switched.

Pulse output scaled: Only for models with NAMUR power supply.

Scaling factor of the scalable pulse output in Pulses/L, which is dependent of the K factor setting:

"10" or "100" if K Factor > 100

"1" or "10" if 10 < K Factor ≤ 100

"0.1" or "1" if 1 < K Factor ≤ 10

"0.01" or "0.1" if K Factor ≤ 1

Flow display: Selection of the flow unit as L/min., L/h or m³/h. The flow value is calculated automatically.

7.3.2 Operating Module (BEZW)

The electronic meter can also be configured within the Ex-area with four passive function keys.

The following data can be changed:

K Factor

The number of digits after the decimal point for the volume display (main meter, return meter and malfunction quantity meter).

Resetting of the main meter with automatic transfer to the sum meter.

The connection of the operating module is done through the interface plug on the connection circuit board. See diagram in chapter 2, System Description.

Setting K factor:

P-Key Programming key. The meter switches to the programming mode. The third identification field from the left is highlighted. The K factor and the decimal point are shown.

+ (>) Key The value of the digit, which is marked by the identification field, is increased by 1 when you push the key.

- (<) Key The value of the digit, which is marked by the identification field, is reduced by 1 when you push the key.

Return key When you push the return key, the next digit to the right of the digit, which is presently marked, is marked by the identification field and can now be set.

When all digits have been set, the K factor is accepted by pushing the return key again and the display then moves to the main meter. The last position of the identification field on the right is highlighted. You can now set the decimal point for the volume display.

Setting the decimal point:

You can change the decimal point in the programming mode in the main meter using the + / - (> / <) keys.

When you push the return key, the decimal point is accepted and the highlighting of the identification field disappears and the display is shown in its basic status. At the same time, the decimal points of the malfunction quantity meter and the return meter are changed along with the main meter.

Setting Meter to Zero:

The simultaneous pushing of the + / - (> / <) keys in the basic status sets the display of the main meter, the return meter and the malfunction quantity meter to zero. At the same time, the sum meter, which cannot be erased, is increased internally by the amount in the main meter. This insures that no volume amount is lost.

8. Alarm and Warning Messages

Alarm and warning messages are shown, when the function "Reaction to Alarm and Warning" is activated.

For meters with NAMUR power supply (AG4XEZD, AG5XEZD), if an alarm or warning message is shown on the LCD display, the corresponding alarm or warning output is switched to "low." The warning output (output 1 or output 3) is activated, if the output behavior is set to "Warning."

The alarm and warning messages can be tested using the SensorPort program. Use the menu "Instrument/Self-test."

The alarm and warning messages can be reset with the switching magnet by touching the "Display" button or through the serial interface with the SensorPort program. Use the menu "Instrument/Reset Meter," function "Delete Alarm and Warning Messages."

After this, the display shows the return meter and the malfunction quantity meter for four times for two seconds each.

The alarm and warning messages can also be deleted with the reset function "Reset all Meters" (R).

Caution! This reset process erases all meter data.
