4 Electrical connections
WARNING: the electrical power supply line must be equipped with a
device to protect against short circuits. In addition, a disconnect device
must be installed (with overvoltage category III, i.e. with minimum contact
gap of 3.5 mm) or an alternative equivalent system, such as a plug and
socket connection. Once the installation is terminated, the power supply
disconnection device must be readily accessible and, if it is not located in
the immediate vicinity of the automation it must be equipped with a lock-
out system to prevent unintentional or unauthorised reconnection.
"RME" series tubular motors must be constantly powered by means of a
permanent connection to the 230V mains circuit.
The motor electrical connections are shown in figure 6.
WARNING: make the connections exactly as indicated; in case of doubt
do not proceed by trial and error: seek assistance from the Mhouse serv-
ice organisation or consult the specific detailed technical datasheets,
which can be downloaded from the Internet site www.mhouse.biz. Incor-
rect electrical connections can cause serious faults and dangerous con-
ditions.
5 Storing the transmitter in the system memory
In "RME" tubular motor kits the supplied TX3 transmitter is already stored in the memory and ready to operate.
When using "RME Start" kits you need to purchase at least one Mhouse transmitter type TX3 or TX4 and then store it in the system memory as descri-
bed in table 3.
Table [3]
Storing the first transmitter (in Mode I)
1
Connect the RME to the power supply; it will emit 2 long beeps
2
Within 5 seconds press and hold down any key on the transmitter you wish to store in the automation memory
3
Release the key when you hear the first of the 3 beeps that are emitted to confirm that the transmitter has
been stored in the memory
If 3 short beeps are emitted when you connect the power supply this indicates that the RME system already contains transmitters in the memory; in this case
you cannot store transmitters as described above – instead, adopt the procedure described in table 9
After storing a transmitter (in Mode I) the transmitter keys will transmit the
commands described in table 4.
Note: until the limit positions have been programmed the motor operates
in "operator present" mode, i.e. it runs only as long as the transmitter key
is pressed; in these conditions commands
that they have the opposite effect.
Additional information and alternative methods for storing trans-
mitters are given in the "Details" section.
6 Programming the limit positions
RME tubular motors are equipped with a controller with an electronic lim-
iter system that stops the movement when the motor reaches the pro-
grammed positions, i.e. the positions with the system completely retract-
ed or the position with the system completely extended. In addition to the
two end positions it is also possible to program an intermediate position,
which can be used, for example, for partial opening of a shutter.
These positions must be stored in the memory with a specific program-
ming procedure that is carried out with the motor installed and the shut-
ter, awning or solar screen mounted.

For the sake of simplicity, the expressions: "roller up", "roller down" and
"intermediate position" have been replaced by the terms "position 0"
(roller up); "position 1" (roller down); and "position I (intermediate), corre-
sponding to the positions shown in figure 7 (for shutters) and figure 8 (for
