1. RECEIVER INSTALLATION
The receiver consists of a splash-proof surface-mount housing with screw-rod antenna (Figure 1) and the electronic board
(Figure2).
Receiver housing of IP-53 allows flexibility in selecting the mounting location. The receiver can be placed directly under the
gatedrivercoveraswellason the post of the fence.
Access to the screw terminals and interface of the receiver is possible after removing the external antenna and sliding the
receivercover.
Beforeconnectingthewiresmustbecarriedthrough the cable hole of 8mm diameter.
Receiverhousing is equipped with theUSB connector cover, so youcan accesstheconnectorwithoutremovingthecover.

Receiver board has a microprocessor control unit with LEDs and buttons; executive elements realized on two relays; and screw
connectorsforconnectingthe power supply, antenna and controlled devices.
The controlled device must be connected to the receiver output. If the device requires normally open (NO) control, connect the
devicetotheterminalsNOandC. If device requires normally closed (NC) control, connect the device to the terminals NC andC.
The receiver is equipped with a rod antenna. In order to increase the radio coverage use an external antenna using coaxial cable
with an impedance of 50Ω. Connect antenna's coaxial cable to the terminal marked (central cord) and to the terminal
markedGND .
12-24V AC/DC connection is indicated by PWR LED. During receiver operation, each switching of C1/C2 output channel is
indicatedbyC1/C2 LED.

2.5. Entering of authentication code (unable for MICRO2 version)
Galactic function allows adding remotes programmed and configured outside the installation, without need to use receiver
buttons.
It is necessary to have remote with Galactic function, remote has to be programmed with authentication code by
GPROGprogrammer.
To enter authentication code to receiver pressC1 orC2 button. C1 orC2 LED lights on and LED indicating currently set working
mode lights on. Press repeatedlyC1 or C2 button to light onG/LOCK LED. LED will pulse.While LED pulsing press and hold for 5
secondstwobuttons of remote withGalacticfunction.
Remote used in this procedure becomes "master" remote. It is neccessary to tag the remote for future use. One
"master"remotecanbeusedforseveralreceivers.
FrequencyofG/LOCKLED pulsing indicates is authentication code set or not.
Very fast pulsing (over10pulsespersecond)indicateslackofGalactic code in the receiver.
Slowpulsing(1pulsepersecond) indicatesGalacticcodeissetinthe receiver.
2.6. DeletingGalactic authentication code (not available for MICRO2 version)
To delete authentication code of Galactic function it is necessary to have "master" remote, that authentication code has been
setwith.
To delete authentication code press C1 or C2 button. C1 or C2 LED lights on and LED indicating currently set working mode
lights on. Press repeatedly C1 or C2 button to light on G/LOCK LED. LED will pulse. While LED pulsing press and hold for 5
secondstwobuttons of "master" remote, that code has been previouslysetwith.

2.8.Service lock.Adding / deleting the "master" remote.
Service lock is a function which switches off operation of remotes added to the receiver at the time of eg. maintenance on the
installation.Enablingservicelockcausethat receiverdoesnot respond to the signal from the remotes.
To activate service lock it is necessary to add "master" remote to the receiver. Adding "master" remote is independent of
adding remotes to the channels. "Master" remote can be used for control of the channel and for switching the service lock as
well.You can enter up to 5 "master" remotes to activate/deactivate the service lock.
To add/delete a "master" remote pressC1 or C2 button. LEDC1 or C2 and LED indicating the currently selected operating mode
MOM / MONO / BIST will light. By pressing the C1 orC2 button repeatedly light theG/LOCK LED.G/LOCK LED will blink. During
this time, press and hold for 3 seconds remote button. C1 LED blinks if "master" remote added, C2 LED blinks if "master"
remotedeleted.
It is recommended that the "master" remote was not added to the receiver and served only to activate/deactivate the
servicelock.
