DESCRIPTION
OG/76 R is a 433.92MHz dual channel "rolling code" radio receiver, suitable for outdoor
installation, to be coupled to the corresponding remote control family (OG/2M, OG/4M). The
appliance has a 12 or 24Vac or dc power supply. OG/76 R can store up to 33 different SERAI
rolling code remote controls, regardless of the number of receiver channels commanded by
each one. Another 780 remote controls can be stored by installing the optional SOG/2 A
memory expansion card, for a total of 813 different remote controls memorised. The
transmitters must be associated to the OG/76 R receiver (1 or 2 channels), by means of the
self-learning procedure in order to operate. The behaviour of 2 output relays (NO contact) can
be configured individually as monostable or bistable (memorising the status in case of a power
failure) with specific dip switches. Each channel is equipped with a button to activate self-
learning or for cancelling, and a specific LED which, if on or flashing, indicates its use in
various situations (command reception, self-learning, cancellation, etc.).
INSTALLATION AND CONNECTION
Installation and subsequent operations must be carried out by qualified personnel
according to plant management laws and standards in force, with all power
disconnected.
The appliance is belt for indoor or outdoor installation, as long as the cable
gland faces downwards. For installation, release the fixing screw and extract the support (1). It
must be hung on a wall using screws with inserts or blocked tightly (even on poles) using self-
locking nylon clamps; pass the cables through the 2 cable glands fixed to the support (2). After
having fixed the support, make the connections using the removable terminal (3). If you need
to change the default factory settings, proceed with step 4 (from 4a to 4f); for example to
replace the wire antenna with the optional OG/50 antenna which increases the capacity of the
remote controls, to assign monostable behaviour to channel 1 and/or 2 instead of bistable.
Power the appliance, program the remote controls (self-learning procedure) and perform the
functional check, plug it back onto the support (5), secure it with the fixing screw and tighten
the cable gland.
ATTENTION!
There is a main isolation (1500V) between the antenna coming out of the appliance,
which could be accessible, and the power supply and relay contacts. Therefore make
sure that both the power supply to the appliance and the loads piloted by the relays are
isolated from the 230Vac mains by a dual safety isolation (4000V), or at least an
additional isolation (2500V).

ATTENTION!
Aim the antenna cable downwards,
arranging it in a straight line
without bending or cutting it.
Having removed the support, extract the
printed circuit by grabbing the edge of
the connector with straight pointed pliers
(4e). Change the default settings as
indicated (4f), then put the circuit board
all the way back into the container,
sliding it on the guides. Reposition the
internal plastic side.
