3.3. Mounting (retrofit) PDC with ex-works
installed ZENNER pulser to corresponding
ZENNER water meters
Please refer to the relevant installation instructions
of the pulser and take the PDC as described in
section 3.4 in operation.
3.4. Commissioning PDC
A) PDC wireless M-Bus: The commissioning is
performed via the optical interface.
The parameters to be programmed using a laptop
with the ZENNER MSS Configurator license, the
universal interface MinoConnectRadio with
Bluetooth interface and the associated special
ZENNER infrared optical head IrCombiHead.
Alternatively, the use of an Android handhelds
with a MeterReaderLight license instead of a
laptop is possible. Activation takes place auto-
matically when the PDC module has received
more than 10 pulses from the meter.
B) The LoRaWAN® PDC module is to be activated and
parameterised by means of the ZENNER infrared
opto head IrCombiHead. Here, an additional
activation by means of illumination (at least 8
seconds) of the IR diodes is possible.
Upon successful activation, the device sends a join
request to the server and waits for acceptance (join
accept).
If no connection is made then a further request is
sent every minute (to a max. of 5 requests). The
indicator light (red LED) indicates the status of the
connection process:
rapid flashing: No reply yet received
■
slow flashing: Successful connection
■
If no successful join is achieved then the device will
send a random join request every day until a
successful connection is made (LED does not display
later attempts to join).
