3.2. Mounting with fixing screw (EDC-S)
Place the EDC on the previously cleaned register and
fasten it with two fixing screws as shown in picture
5. Then stick the two yellow adhesive security seal
stickers over the screws. If necessary the water
meter lid has to be changed against the supplied lid
which is fitting with the EDC
Fig. 4: Mounting of the EDC-C
Attention:
Before retrofitting the EDC modules,
make sure that the register is free of dirt
and that the EDC can be mounted as
intended.
Make sure that the EDC is positioned correctly and
check that the EDC sits horizontally on the
register. Improper mounting as shown in the f
ollowing sketches (Fig. 6) prevent reliable scanning
of the modulator disc and lead to differences
between the counter reading of the roller counter
and the transmitted counter reading.

The parameterisation on site is only necessary for
subsequent installation of the EDC module on a
water meter.
Settable parameters:

With the EDC wM-Bus variant of the first generation
the activation of the wireless M-Bus radio signal per-
forms automatically, as soon as the function "pulse
enabled" is activated and the EDC module scans 30
pulses from the register. With EDC wM-Bus V2 devic-
es, the activation is no longer automatic after x liters
of flow, but by means of software and opto head or
alternatively by illuminating the infrared interface
> 8 seconds. As a light source, please do not use an
LED. When using the MSS software and opto head,
please click on the clickbox "SetOperationMode" in
the software interface to activate the EDC module V2
(from fw. 1.78). After activation, the red LED flashes
for a duration of one minute. The current status of
the register is programmable by means of the optical
head via the optical interface of the EDC module.
A ZENNER PC-software is required for programming.
The configuration is made by means of a ZENNER
software, the universal interface MinoConnect and
the specific ZENNER infrared optohead IrCombi-
Head.
The LoRaWAN® EDC module is to be activated and
parameterized by means of an opto head in case of
a retrofit. For ex-works installed EDC module on a
water meter no further parameterization or radio ac-
tivation necessary, because the radio function starts
automatically after flow detection (flow rate depends
on meter type). 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 suc-
cessful connection is made (LED does not display
later attempts to join).
