Product description

The K series radio control device is a system which enables the user to remote control door opening devices, gate opening devices and similar systems.
The system works by transmitting and receiving a digital code featuring 1024 combinations for each transmitter button.
The available receivers are:
Version Power input
KX1 12/24 Vac/dc
KX2 12/24 Vac/dc
KXI 24 Vac/dc
KXI2 24 Vac/dc
FLOXM 12/24 Vac/dc
FLOXM220 230 Vac
Installation: Receivers
The KX1, KX2 and KXM receivers can be powered by 24Vac/dc or 12Vac/dc. The power input mode can be selected by means of a jumper with tab (ref. A fig.3 ). The
KXM receiver is switched on by means of a spring return selector switch (ref.A fig.4).
!
Make sure the power input mode is correct before powering the receiver.
In all the versions, the receiver outputs are normally open (N.O.) pure contacts provided by the relays on the board. In the KXM and KXM220 versions, the outputs are
provided through the plug-in relay units (ref. M fig.4); there are three kinds of relay unit:
MXD: this output is impulsive, that is, it remains active as long as the command signal remains.
MXP: this output is step-by-step, that is, each command signal switches the status of the relay contact.
MXT: this output is timed, that is, after being activated it remains so for a period of time that can be adjusted from 3 seconds to about 5 minutes (use a maximum of 2 MXT units).
If a normally closed "NC" type of contact is needed, for versions FLOX1, FLOX2, FLOXB2, FLOXI and FLOXI2 proceed as follows
1. Disconnect the receiver (KX1, KX1) if powered or remove the board from the slot (KXI and KXI2).
2. Open the receiver box and remove the board with care (KX1, KX2).
3. On the solder side of the receiver: cut the copper section at point A and then connect the bump contacts with a spot of solder in point B (fig.9)
In the KXM and KM220 versions, proceed as described in points 2 and 3 on the solder side of the relay units (fig.6).
!
If more than one receiver is installed close to each other, make sure they are over 50 cm apart in order to prevent interference.
Associating transmitter buttons with receiver output: The KXM and KM220 receivers feature 4 slots for the relay units, each one of which corresponds to a button on the
transmitter (fig.4). For the KX1, KXI, KX2 and KXI2 receivers, each output relay is associated with a certain button by inserting a selection jumper (ref. C fig.3): for the KX1
and KXI receivers, refer to figure 7a; for the KX2 and KXI2 receivers, refer to figure 7b.
Entering the code: set the 10 dip switches (ref. B fig.3 and 4) to ON – OFF in order to create the required combination.
Installation: aerial
To guarantee optimum performance, each K receiver must be installed with its own ABK or ABKIT aerial. The aerial must be installed as high as possible; if there are metal
structures or reinforced concrete walls nearby, install the aerial on top of them. If the cable supplied with the aerial is too short, use a coaxial cable with an impedance of
52 ohms (e.g.: RG58 with low dispersion); the total length of the cable must not exceed 10 m. Connect the aerial to the relative terminal (fig.3 and 4) by connecting the
central part (core) to terminal 2 and the braid to terminal 1.
If the aerial must be installed where there is not a good earth level (e.g.: masonry structures), terminal 1 of the aerial can be earthed to obtain a wider range of action; this
is clearly advantageous if the quality of the earth connection is good and it is located in the immediate vicinity. Good results can be obtained, however, by using an 18 cm
long piece of wire, mounted horizontally and connected to terminal 2 of the aerial input, as an aerial.
Installation: transmitters
Setting the code: Open the transmitter (fig.12 and 13) and set the 10 microswitches with the same combination as the receiver.
Associating the transmitter key - receiver output: on transmitters K1-K2 (fig.5) , K1M-K2M (fig.8), besides the 10 microswitches used for setting the code, there are
additional microswitches that allow a receiver output to be associated with the transmitter keys (fig. 11); on transmitters K4 and K4M the association of key and output
cannot be modified; transmitters K2+2 (fig.5) allow you to activate the OUT1 and OUT2 outputs of a receiver through keys T1 and T2, while the other two T1 and T2 keys
can activate the OUT1 and OUT2 outputs of another receiver having a different digital code.

Maintenance

The receiver requires no maintenance whatsoever. The battery in the transmitter must, however, be replaced whenever there is a significant loss of range. Open the stan-
dard transmitter as shown in Figure 12 and the mini-transmitter as shown in Figure 13 in order to replace flat batteries.
