Replacement
▷
The ACM WAVE SYSTEM RF units are matched
together in pairs. This means that once the bat-
tery 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.

2
▷
If the RECEIVER/REPEATER needs to be opened
for removing the base plate, the seals on the
units must also be pierced and broken with a
screwdriver.
4
Install the new ACM WAVE SYSTEM RF accord-
ing to the enclosed operating instructions.
Maintenance
The ACM WAVE SYSTEM RF for gas meters with
Absolute ENCODER AE2 requires little servicing.
Assistance in the event of

Remedy
Possible faults and suggested solutions
?
The red LED does not blink after connecting
the TRANSMITTER.
!
The contacts on the index are bent.
•
Remove the TRANSMITTER from the index and
straighten the contacts. Re-attach the TRANS-
MITTER.
!
The TRANSMITTER has been incorrectly fitted.
•
Fit the TRANSMITTER according to the enclosed
operating instructions.
?
M-Bus communication with the RECEIVER
is disturbed.
!
The connection plug in the RECEIVER is not
plugged in.
•
Check the connection plug and plug in.
!
The connection cable on the RECEIVER is incor-
rectly connected.
•
Check the connection cable, see page 2 ().
?
The green LEDs on the REPEATER and the
RECEIVER do not blink simultaneously.
!
The REPEATER has found a “foreign” RECEIVER,
e.g. in a neighbouring room.
•
Hold the REPEATER closer to the RECEIVER.
?
If the REPEATER is too far away from the
RECEIVER, the green LED goes out.
!
The wireless link is too large.
•
To support the wireless link, use an additional
REPEATER. Position the first REPEATER where it
will receive a sure signal from the RECEIVER. The
second REPEATER must now be synchronized
with the first REPEATER. To do this, follow the
instructions on page 4 (Synchronizing the
REPEATER with the RECEIVER).
?
The network operator cannot receive any
data, despite successful installation?
!
The wireless link has subsequently been inter-
rupted, e.g. by a door being closed that was
open during installation.
•
To support the wireless link, use a REPEATER.
To install, the RECEIVER and the TRANSMITTER
must be set back to installation mode.
Activating installation mode
1
Loosen the flat head screw on the TRANSMIT-
TER and pull the TRANSMITTER off the index.
▷
The dismantled TRANSMITTER will return to
installation mode after one hour.
2
Now reconnect the TRANSMITTER to the index.
▷
When connecting the TRANSMITTER to the
index, avoid bending the contacts.
▷
The red LED on the TRANSMITTER blinks.
Loosen the housing cover on the RECEIVER and
pull it off.
4
Place a jumper on both pins.
5
Wait until the red LED blinks.
▷
The RECEIVER is once again in installation mode.
6
Pull the jumpers off the pins.
7
Place the housing cover on the RECEIVER and
tighten the screws.
8
Now synchronize the REPEATER first with the
RECEIVER and then with the TRANSMITTER,
see page 4 (Installing the REPEATER).
