Connect the 6 wires of the receiver cable to the relative termi-
nals of the control unit as follows (
fig. 3
):
• Red
and
Black =
POWER SUPPLY
(red =
Positive
, black =
Negative.
In AC this is not impor-
tant).
• White
and
White =
RELAY 1 OUTPUT
(voltage-free contact of a normally open relay).
• Purple
and
Purple =
RELAY 2 OUTPUT
(voltage-free contact of a normally open relay).
–– How to obtain “
NC
” type contacts ––
The outputs are controlled by 2 relays with NO (normally open)
type contact. To change to NC (normally closed) type contact,
proceed as follows:
01.
Disconnect the receiver from the power supply.
02.
Open the box of the receiver by first raising the smaller
section of the cover (
fig. 4
-
a
) and then the larger section
with the key (
fig. 4
-
b
).
03.
Carefully remove the board and turn it over:
the side with
the soldered elements must be facing the user.
04.
On the side with the soldered elements, proceed as fol-
lows (
fig
.
5
):
–
Cut the traced section at point “
X
”
–
Join the contacts with a drop of tin at points “
Y
”.
Note
– these modifications may be applied to one or
both relays as required.
