Depending on the register version (standard dry dial
or copper-can) two different EDC casing types are
available:
3.1. Mounting (retrofitting) with fixing clip/screw
(EDC-C)
Remove the metallic sticker from the bottom of
the EDC module. Place the EDC on the previously
cleaned register as shown on picture 4 and press it
firmly. Make sure that the screw passage and the
recess in the register cap fit correctly. Additionally,
secure the EDC with the enclosed fixing screws. 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 fit
-
ting with the EDC module.
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 module
.
4. Configuration
The parameterisation on site is only necessary for
subsequent installation of the EDC module on a
water meter.
Settable parameters:
■
Current value on the register
■
The water meter number related to the EDC
module
■
Pulse value of the modulator disc
■
Resetting of the status bits (tampering, error)
■
Resetting of all logger values (in case of
replacement of the water meter and further
use of the EDC module)
■
Setting of the pulse length (ms)
■
Setting of the output pulse value
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. 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 wa
-
ter meter no further configuration is needed. 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).
