10.5 Integrated data logger
The integrated data logger stores the consumption
values and current values. The logger can record
values of 1200 hours, 120 days and 120 months.
The logger data can be read out via an optical
interface or M-Bus with the MiniCom 3 service
software.
As part of the integrated data logger, the device
also stores 500 events and 500 changes of error
situations.
10.6 Wireless M-Bus, (wM-Bus)
If the meter is equipped with a wM bus, it has an
internal antenna. Two modes, C1 and T1, can be
selected.
The meter is certified in accordance with OMS
Specification, Volume 2, Version 4.0.2 of OMS.
This ensures optimum compatibility with all OMS-
compatible readout systems.
Mode C1 is set to a transmission interval of 16
seconds by default. Individual 128-bit encryption is
performed.
Mode T1 is set to a transmission interval of 900
seconds by default. Individual 128-bit AES
encryption is performed.
With the Sensus readout software DIAVASO, the
customer can read out the meter data with both T1
and C1 modes.
By default, wM-Bus data transmission is disabled.
The wireless M-Bus data transmission can be
switched on either in the LCD menu structure level
6 or with the MiniCom 3 software.
The configuration of the wM-Bus data transmission
mode and the telegram packet types can be
changed using the MiniCom 3 software.
The frequency of wireless transmission is 868.95
MHz, and the maximum transmission power is 25
mW (14 dBm).
11. Battery supply
Depending on the version, the PolluCom
®
F/S C is
supplied with 1 or 2 lithium batteries (type AA). For
optimum battery life, ensure that the battery
temperature does not exceed the permissible
ambient temperature, e. g. by split design with wall
mounting.
The voltage of a lithium battery is almost constant
over the entire battery life. In the service menu of
level 4 of the LCD display, the currently battery
voltage is displayed behind the voltage control
circuit. It should be constant at approx. 3.0 V. If this
voltage drops below 2.9 V, a warning code 0200
will appear in the LCD display and the meter should
be replaced as soon as possible.
Note: The battery of the PolluCom
®
F/S C cannot
be replaced or charged.
The typical service life of the PolluCom
®
F/S C is 8
years. Depending on the options selected and the
configuration, a battery life of up to 15 years can be
achieved. The duration of use is based on national
guidelines.
