3. Installation respective retro -
fitting of the PDC to a meter
The ZENNER PDC modules are designed primar-
ily for all water meters of ZENNER which can be
retrofitted with a pulse generator (model -N). Basi-
cally, a PDC can be connected to any meter with
suitable pulse output.
3.1. Connection (retrofitting) of PDC IP68
with open cable end to meter with existing
pulse output
Connect the pulse output of the meter with the
PDC-cable. Use a cable connector and possibly
observe the correct polarity.

3.2. Connection (retrofitting) PDC IP54 with
pulse output of any meter

3.3. Mounting (retrofit) PDC with ex-works
installed ZENNER pulser to corresponding
ZR-water meters
Please refer to the relevant installation instruc-
tions of the pulser and take the PDC as de-
scribed in section 3.4 in operation.
3.4. Commissioning PDC
The commissioning is performed via the optical
interface.
The parameters to be programmed using a laptop
with the Global ZENNER meters Manager (GMM)
software (Configuration Manager license), the
universal interface MinoConnectRadio with Blue-
tooth interface and the associated special ZEN-
NER infrared optical head IrCombiHead. Alter-
natively, the use of an Android handhelds with a
MeterReaderLight license instead of a laptop is
possible.
Configure at least:
serial number of meter connected to the PDC
■
module
Initial value = present value of the register of the
■
connected meter
Pulse value of the connected meter
■
The respective transmission interval is preset.
Additional setting parameters:
Reset logger values
■
Reset status bits (manipulation, error)
■
AES-key (depending on the software license)
■
Activation takes place automatically when the
PDC module has received more than 10 pulses
from the meter.
