RELAY OUTPUT: clean contact of a normally open
relay (only on receivers with 2 channels).
1-2 AERIAL: aerial signal input.
––– Installing an external aerial
–––
If the aerial provided is in an unfavourable position and the
radio signal is weak, we recommend you improve reception
by replacing the aerial through the installation of an external
one (mod. ABF or ABFKIT). The new aerial should be posi-
tioned as high as possible and above any metallic or rein-
forced concrete structures in the area.
If necessary, use a coaxial cable with an impedance of 50
ohm (for example, the RG58 low-loss cable). Important! –
To reduce signal dispersion, use the shortest possible cable
(it should not exceed 10 m in length).
– Aerial connection
(only for models with universal con-
nection): connect the aerial cable to terminal 1 and 2 (fig.
2): terminal 1 = sheath; terminal 2 = core.
– Aerial connection for models with Nice connector
:
connect the aerial cable to the purpose-provided terminals
on the control unit.
• For all models:
––– Relay selection on channels –––
Each receiver is designed to recognise all 4 keys on the
transmitter. This is possible thanks to the association of the
output relays with the desired key, through an electric jumper
which should be inserted in the purpose-provided connec-
tors: see Table 1.
––– How to obtain “NC” type contacts
–––
The outputs are operated by 2 relays with a “NO” (normally
open) type contact. If you want to achieve a “NC” (normally
closed) contact, proceed as follows:
01. Disconnect the electrical power supply to the receiver.
02. Remove the board carefully and turn it over: the side
with the welding should be facing you.
03. On the side with the welding, carry out the following
steps (fig. 3):
– Cut the section of line at point “X”.
– Using a drop of tin, join the spots at points “Y”.
Note – these changes can be made on one relay or on both,
depending on your requirements.
