Installing the gas meter
▷
For installing the gas meter in the pipework, refer
to the operating instructions for diaphragm meters BK-G1.6 to BK-G25T, see www.docuthek.
com → Elster-Instromet → Products → Gas
measuring devices → Diaphragm meters →
Diaphragm meters BK-G1.6 to BK-G25T operating instructions.
Attaching the TRANSMITTER
▷
The TRANSMITTER is connected to the Absolute
ENCODER AE2 index after the gas meter has
been installed in the pipework.
▷ The retaining screw and the calibration seal are
found at the rear of the TRANSMITTER housing.
▷
When connecting the TRANSMITTER to the
index, avoid bending the contacts.
GB
▷
Feed the new connection cable into the strain
relief facility, see figure 5 . Otherwise, the
RECEIVER cannot be closed.
▷ The red LED on the TRANSMITTER blinks.
▷
If the red LED does not blink, see page 5
(Assistance in the event of malfunction).
Wiring completed
▷
Once wiring is completed, the RECEIVER requires a charging time of < 5 min. During this
time, there is no communication with the other
units of the ACM WAVE SYSTEM.
▷ At the end of the charging time, the green LED
on the RECEIVER blinks every 10 s and the red
LED blinks at a rate of 1 Hertz.
▷
The charging time can be used for further in-
stallation work, see page 3 (Closing and
sealing the RECEIVER) and 3 (Installing the
gas meter).
Closing and sealing the RECEIVER
▷ Secure the RECEIVER against external access
with the seal.

Installing the TRANSMITTER/RECEIVER
▷
The ACM WAVE SYSTEM RF units are delivered
fully programmed.
▷
Once the RECEIVER has been wired and the
TRANSMITTER has been connected to the in-
dex, the units and the connected receiving unit
are synchronized automatically. The RECEIVER
and the TRANSMITTER are in installation mode.
▷ When the units have “found” each other, all the
LEDs go out after a maximum of 20 s. The red
LED on the RECEIVER now blinks once every
20s.
GB
▷
The LEDs do not go out? See page 4 (Syn-
chronizing the TRANSMITTER/RECEIVER failed).
Synchronizing the TRANSMITTER/RECEIVER failed
▷ If the distance between the RECEIVER and the
TRANSMITTER is too large, the units will not
“find” a sufficient signal. This can be identified
by the continued blinking of the LEDs on the
RECEIVER and the TRANSMITTER.
▷
To support the wireless link, a REPEATER can be
connected. Up to 3 REPEATERS can be used.
See page 4 (Installing the REPEATER).
Installing the REPEATER
Synchronizing the REPEATER with the
RECEIVER
1 Hold the REPEATER close to the RECEIVER.
2 Activate the REPEATER. To do this, place a per-
manent magnet in close proximity to the two
LEDS for approx. 10s. A magnetic flux density
of B ≥40mT directly on the housing surface is
needed for identification purposes.
▷ The REPEATER is activated when the red LED
blinks every 2 s.
Synchronizing the REPEATER with the
TRANSMITTER
4 Move the REPEATER in the direction of the de-
sired installation location and the TRANSMITTER.
▷
When doing this, the signal between the
REPEATER and RECEIVER must not be “lost”.
The green LED must continue to blink.
▷ When the green LED on the REPEATER blinks
twice within 10 s, it means that the REPEATER
and the TRANSMITTER have found each other.
Synchronizing the REPEATER failed
▷
If the REPEATER is too far away from the
RECEIVER, the green LED goes out. The signal from the RECEIVER is “lost”. Move the REPEATER back in the direction of the RECEIVER
until the green LED blinks again.
▷ It is not possible to position the REPEATER so
that the green LED on the REPEATER blinks
twice within 10 s? See page 5 (Assistance
in the event of malfunction).
Finishing installation
5 Confirm installation. To do this, hold the perma-
nent magnet on the LEDs on the REPEATER for
approx. 10 s.
▷
The red LED on the REPEATER briefly blinks
more quickly. Afterwards, all the LEDs on the RECEIVER, REPEATER and TRANSMITTER go out.
6 Secure the REPEATER, see page 2 (Attach-
ing the RECEIVER base plate).
Closing and sealing the REPEATER
▷ Secure the REPEATER against external access
with the seal.
▷
When the green LEDs on the REPEATER and
the RECEIVER blink simultaneously every 10 s,
it means that the units have found each other.
▷
The green LEDs do not blink simultaneously?
See page 5 (Assistance in the event of malfunction).
Confirm that both units have been synchronized.
To do this, hold the permanent magnet on the
LEDs on the REPEATER for approx. 10 s.
▷
The green LEDs on the REPEATER and the
RECEIVER no longer blink simultaneously.
▷ The red LED on the REPEATER now blinks at a
rate of 1 Hertz.
▷
The REPEATER now “seeks” the TRANSMITTER.

Replacement
▷
The ACM WAVE SYSTEM RF units are matched
together in pairs. This means that once the battery life has expired, the complete ACM WAVE
SYSTEM RF must be replaced.
▷
The units can be replaced without further pro-
gramming effort.
▷
The relevant calibrated part of the meter remains
unaffected.
1 For removing the TRANSMITTER, the seal must
be pierced and broken with a screwdriver.
