General speciﬁcations EDC M-Bus and pulse:

Number of conductors 5

Cable length 1,5 m

Electromagn.

Compatibility

fulfils the European

Directive 89/336/EWG

Function Pulse output

Type P1 balanced

pulses

The combined M-Bus and pulse module has

been developed specically to enable the simul-

taneous readout by two different users. In this

case the pulse version will be delivered by stan-

dard as type P1.

8. Combined M-Bus/Pulse

module

Important note

For EDC applications with simultaneous use of pulse

output and M-Bus interface, only battery powered or gal-

vanically isolated pulse modules can be connected to

the pulse outputs. Otherwise, the EDC module may be

damaged in the case of a potential difference between the

connected devices.

9. AES-Key

The EDC-modules send their data contents only

encrypted (AES-128, device-specic according to

OMS, optionally customer-specic). To enable re-

ception of the data contents and their further pro-

cessing, the AES-Key has to be furnished to the

respective recipients of the AES-Key. ZENNER

provides the AES keys to the devices usuallyby

means of electronic delivery or by customer-spe-

cic le.

10. Readout Data logger

The EDC modules have an internal memory

(data logger). The readout of the data which are

not already transmitted in the above data tele-

grams is carried out by means of the optical head

and GMM software.

Data logger:

Annual due date values: max. 16

Monthly values

18, plus 18

semi-monthly values

Daily values 96

Quarter hour values 96

EDC Data logger

11.

Smart Metering functions

Self-monitoring:

The module has an integrated battery status monitoring.

Tampering detection:

It will be detected as soon as the scanning coils

of the EDC module are affected by a magnet. In

the event memory date and time of the event will

be memorized.

Dismounting of module and meter

detection:

The detection is possible at all meters with grey

as the EDC module was dismounted from the

time of the event.
