In order to avoid false alarms due to short-term air build-up in the meter, the info code DRY is not added to
the relevant registers until it has been continuously active for 30 minutes.
DRY is saved with a date stamp in both the daily register for 460 days and the monthly register for 36 months.
Furthermore, it is saved in the info code register of the latest 50 info code events. Together with the info
code event, a time indicator with 7 time intervals (which indicates how long the info code has been active)
is registered.
Correspondingly the info code DRY is not added to the Wireless M-Bus signal until it has been continuously
active for 30 minutes. Furthermore, if the info code DRY has been active within the latest 30 days, a time
indicator with 7 time intervals indicates in the Wireless M-Bus signal how long the info code has been active.
Infokode
–
REVERSE
This info code indicates that the water in the meter flows in the wrong direction.
Info code REVERSE activates when the water runs backwards in the meter
at a flow, which numerically
exceeds Q
1
for 5 consecutive minutes.
The code disappears from the display when the water is stagnant, or again runs in the correct direction in
the meter. It can take up to 64 seconds until the info code disappears.
The alarm REVERSE is saved with a date stamp in both the daily register for 460 days and in the monthly
register for 36 months. Furthermore, it is saved in the info code register of the latest 50 info code events.
Together with the info code event a time indicator with 7 time intervals, which indicates how long the info
code has been active, is registered.
The Wireless M-Bus signal includes the code REVERSE. If the code REVERSE is active or has been active within
the latest 30 days, a time indicator with 7 time intervals will indicate how long the info code has been active.
Reverse flow is counted and logged in a separate internal register in the meter and can only be read on a
monthly basis. If a meter has been incorrectly installed (with reverse flow direction) for a longer period, the
reverse volume could be read in the monthly logger. This log is, similar to the legal log, an absolute log
–
which means that the total reverse consumption are shown in the latest monthly log at the end of the month.
So even if the fault is corrected, the total reverse consumption can not be seen until the end of the month.
The total reverse volume is measured and recorded whether the info code is being activated or not.
It should be emphasized that the register for backwards volume is NOT covered by the type approval, and
therefore not approved for billing purposes.
The register can only be read via the optical eye with LogView.
The legal volume register, V1, and thus the meter reading is not affected by the reverse flow.
Info code
–
RADIO OFF (transport mode)
This info code is active in the display when the water meter leaves Kamstrup A/S, and indicates,
that the ete is still i t a spo t ode a d that the uilt
-in Wireless M-Bus radio transmitter has not yet
been activated.
In transport mode the meter displays info codes, if any. These are not logged into the corresponding
registers, and are not added to the corresponding hour counters.
The Wireless M-Bus radio transmitter activates when water starts flowing and the meter has registered
approx. 6 seconds of continous water flow. The radio transmitter remains active.
The info code RADIO OFF is a info code signal, which either flashes, or is inactive. When RADIO OFF flashes
in the display, the radio is off. When the RADIO OFF signal is inactive/not shown in the display, the Wireless
M-Bus radio transmitter is on.
This info code is
a displa ode
which is not included in the Wireless M-Bus radio signal.
