switching magnet.
The display changes depending on how long you touch the "Display" button.
Each display can be identified with the symbols in the identification window.
U
•
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.
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.

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:
Main meter is decremented during return:
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
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

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.
