LG 2279 TERMINAL BOARD DESCRIPTION
1
Terminals 1 and 2
: power supply for the
actuators. Connection for supplying power to
24Vdc actuators with maximum absorption of
8A.
2
Terminals 3, 4 and 5
: open/close command
(local). Contact for commanding opening and
closing of the actuator. The operation of this
contact has priority over terminals 6, 7 and 8.

Terminals 6, 7 and 8
: open/close command
(local). Contact for commanding opening and
closing of the actuator without any priority.
When the centralised contact is enabled, every
function is disabled and is re-enabled only
when the centralised contact is in the rest
position.
4
Terminals N and L
: 230 V, 50 Hz power
supply.
L = PHASE
N = NEUTRAL
Attention :
Connect the Rain Sensor to either " 4 and 5 "
or to " 3 and 4 " as required, making sure that
the ”emergency rain“ gives always the closing
command.
