RECEIVER INSTALLATION
For the optimal operation between transmitter and receiver, we recom-
mend you choose the point of installation carefully. The range is not
merely linked to the technical features of the device itself, but it actually
varies according to the radioelectric conditions of the area.
The receiver is fitted with an antenna consisting of a rigid wire section.
Should you wish to increase the device sensitivity, you can connect a
tuned antenna using a RG58 50 OHM coaxial cable. The antenna
should be placed on the exterior in a visible position away from any
metallic structures.
The installation of two receivers placed less than 5 metres from one an-
other is not possible.
OPERATION WITH RADIO-CONTROLS AND/OR TRANSPONDERS
The receiver can be combined with MOTORLIN radio-controls and/or
transponders and is designed to store up to 500 different users. We
therefore recommend you make a note of the “memory position - user
name” correspondence in the form provided. For use with radio-con-
trols, the receiver is fitted with an incorporated receiver.
PROGRAMMING RADIO-CONTROLS AND/OR TRANSPONDERS
The programming of radio-controls and/or transponders is self-learning,
as follows.
Use the UP or DOWN keys to go to the desired memory position
(viewed on the display from 001 to 500), paying attention to the
TRANSMITT R and TRANSPOND R L DS, as one of them turning
on means the location is busy. Press the S L key, the TRANSMITT R
and TRANSPOND R L DS will begin to flash, and meanwhile send
the code with the radio-control or bring the transponder closer to the
“ML3” proximity reader, (the display will indicate STO stored), the
TRANSMITT R or TRANSPOND R L D will go from off to on and pro-
gramming is thus complete.
To delete a radio-control or transponder stored previously, use the UP
or DOWN keys to go to the memory location that is busy, press the
S L key, the TRANSMITT R or TRANSPOND R L D will begin to
flash; press the S T key (the display will indicate "DEL" deleted), the
L D will go from on to off and delete is thus complete.
During normal operation, the display panel indicates the memory loca-
tion of the device stored previously currently in use.
RAPID PROGRAMMING OF RADIO-CONTROLS AND/OR TRANSPONDERS
The rapid programming of radio-controls and/or transponders is only al-
lowed when all the receiver memory is free. To make sure that all the
memory is free, follow the Rese procedure.
Rapid programming means you do not have to select a new memory
location for another radio-control and/or transponder every time, but
starting from position 001, the control unit automatically increases the
memory location and remains on standby for 10 seconds, from the in-
put of a new radio-control and/or transponder to store.
PASSWORD
Once you have finished programming the radio-controls and/or
transponders, you can store a password in the PAS position, to disable
and enable receiver programming, as follows.
Use the UP or DOWN keys to go to the PAS memory position, press
the S L key, the TRANSMITT R and TRANSPOND R L DS will be-
gin to flash, and meanwhile use the UP or DOWN key to select a num-
ber between 001 and 500, press the S T key, (the display will indicate
"CLO" closed), and the TRANSMITT R and TRANSPOND R L DS
will go from off to on.
To re-enable programming, use the UP or DOWN keys to go to the
PAS memory position, press the S L key, the TRANSMITT R and
TRANSPOND R L DS will begin to flash, meanwhile use the UP or
DOWN keys to select the key number selected previously, press the
S T key, (the display will indicate OPE open).
To delete a password (operation only allowed if the system is open
OPE), use the UP or DOWN keys to go to the PAS memory position,
press the S L key, the TRANSMITT R and TRANSPOND R L DS
will begin to flash and meanwhile press the S T key (the display will in-
dicate DEL deleted), the TRANSMITT R and TRANSPOND R L DS
will go from on to off.
N.B.: if you enter an incorrect password, you will have to wait 5
minutes to repeat the operation, and if you enter another incorrect
password, you will have to wait 1 hour.
RESET
If it is appropriate for the factory configuration to be restored (operation
only allowed if the system is open OPE), press the S L and S T keys
simultaneously, and the L DS will turn off, and the display will indicate
the PAS position.
N.B.: the display is turned off after one minute of inactivity to save en-
ergy.
FURTHER FUNCTIONS VIA PC CONNECTION
The receiver can be connected to a Personal Computer through the
use of a “SW 2189” package supplied as an optional, thanks to which
you may access further functions.
FOR THE INSTALLER - IMPORTANT
−All operations requiring the opening of the casing
(such as installation, programming and repair, etc.) must be
carried out by s illed staff only.
−The fixing of power supply leads and connection cables must be
secured through the use of cable clamps.
