Checking the usage
Communications module ACM..WIRE for gas
meters with Absolute ENCODER AE2
Communications module ACM..WIRE for recording
and forwarding absolute meter readings.
ACM M-BUS WIRE additionally offers the “V-Drive”
option. This means that activation and status mes-
saging of the valve incorporated in the gas meter can
be carried out. The valve is designed for the remote
connection and disconnection of the gas supply.
This function is only guaranteed when used within the
specified limits – see page 4 (Technical data). Any
other use is considered as non-compliant.

WARNING
Electric shocks can be fatal! Before working on
possible live components ensure the unit is discon-
nected from the power supply.
▷
For the electrical connection between the
ACM..WIRE and the receiving unit, polarity is
inconsequential.
1 Wire the ACM..WIRE to the receiving unit.
▷ If a connection cable is already routed to the
receiving unit at the installation location, the pre-
fabricated connection cable on the ACM..WIRE
may be removed, as described below.

Installation
Installing the gas meter
▷ For installing the gas meter in the pipework, refer
to the operating instructions for diaphragm me-
ters BK-G1.6 to BK-G25T, see www.docuthek.

Attaching the ACM..WIRE
▷
The ACM..WIRE is connected to the Absolute
ENCODER AE2 index after the gas meter has
been installed in the pipework.
▷ The retaining screw and a calibration seal are
found at the rear of the ACM housing.

Commissioning
Synchronization
▷The ACM..WIRE communications module is de-
livered fully programmed.
▷ Once the ACM..WIRE has been connected to
the index and wired to the receiving unit, the
units are synchronized automatically.
Charging time
▷
The cable-based ACM..WIRE operates without a
battery. The internal energy accumulator ensures
a minimum charging time of < 1 minute between
each valve operation. Only the first charging pro-
cess causes a start-up time of max. 20 minutes.
Communication with the index is possible during
this time. Valve operation is possible on comple-
tion of the charging process.
Replacement
▷ The units can be replaced without further pro-
gramming effort.
▷
The relevant calibrated part of the meter remains
unaffected.
1 For removing the ACM..WIRE, the seal must be
pierced and broken with a screwdriver.

4 Install the new ACM..WIRE according to the
enclosed operating instructions.
Maintenance
The communications module ACM..WIRE for gas
meters with Absolute ENCODER AE2 requires little
servicing.
Assistance in the event of
malfunction
WARNING
Electric shocks can be fatal! Before working on
possible live components ensure the unit is discon-
nected from the power supply.
? Fault
! Cause
• Remedy
Possible faults and suggested solutions
? Communication with the index is disturbed.
