WARNINGS
This manual is designed to assist qualied installation personnel only. It contains no information that may
be of interest to nal users. This manual is enclosed with control unit K126MA and may therefore not be
used for dierent products!
Important warnings:
Disconnect the mains power supply to the board before accessing it.
The K126MA control unit has been designed to control an electromechanical gear motor for automating
gates and doors of all kinds.
Any other use is considered improper and is consequently forbidden by current laws.
Please note that the automation system you are going to install is classi ed as “machine construction” and
therefore is included in the application of European directive 2006/42/EC (Machinery Directive).
This directive includes the following prescriptions:
- Only trained and qualied personnel should install the equipment;
- the installer must rst make a “risk analysis” of the machine;
- the equipment must be installed in a correct and workmanlike manner in compliance with all the
standards concerned;
- after installation, the machine owner must be given the “declaration of conformity”.
This product may only be installed and serviced by qualied personnel in compliance with current, laws,
regulations and directives.
When designing its products, TAU observes all applicable standards (please see the attached declaration
of conformity) but it is of paramount importance that installers strictly observe the same standards when
installing the system.
Unqualied personnel or those who are unaware of the standards applicable to the “automatic gates and
doors” category may not install systems under any circumstances.
Whoever ignores such standards shall be held responsible for any damage caused by the system!
Do not install the unit before you have read all the instructions.
INSTALLATION
Before proceeding, make sure the mechanical components work correctly. Make sure the gate
runs freely on a at surface. Then make sure that the power consumption of the gear motor is
not greater than 3A (otherwise the control panel may not work properly). Havig followed the
previous points, now make sure the motor has a proper absorption. The K126 board starting
from V5.17 release integrates a function to verify the absorption on the complete gate journey
(Check paragraph ABSORPTION CHECK FUNCTION).
THE EQUIPMENT MUST BE INSTALLED “EXPERTLY” BY QUALIFIED PERSONNEL AS REQUIRED BY LAW.
Note: it is compulsory to earth the system and to observe the safety regulations that are in
force in each country.
IF THESE ABOVE INSTRUCTIONS ARE NOT FOLLOWED IT COULD PREJUDICE THE PROPER WORKING
ORDER OF THE EQUIPMENT AND CREATE HAZARDOUS SITUATIONS FOR PEOPLE. FOR THIS REASON
THE “MANUFACTURER” DECLINES ALL RESPONSIBILITY FOR ANY MALFUNCTIONING AND DAMAGES
THUS RESULTING.

ATTENTION:
- do not use single cables (with one single wire), ex. telephone cables, in order to avoid break-
downs of the line and false contacts;
- do not re-use old pre-existing cables;
- In case of long sections of cables (> 20 m) for N.O./N.C. controls (e.g. OPEN / CLOSE, STOP, PEDE-
STRIAN, etc.), in order to avoid gate malfunctions, it will be necessary to uncouple the various
controls using RELAYS or using our 750T-RELE device.
2. INTRODUCTION
The K126MA board has two working modes, selectable through the J6 jumper (see wiring diagram).
J6 Jumped: standard mode, i.e. the control unit is powered all the time;
J6 Not jumped: low consumption mode, at the end of each maneuver the board automatically switches
OFF itself and all the auxiliary devices connected. The board will automatically switch
ON again activating the OP/CL contact or pressing the remote (mode where power is
supplied by other energy sources, ex. batteries charged by a photovoltaic panel).
Once the connection is achieved, in low-energy mode, press the PROG button briey:
• All the green LEDs must be on (each of them corresponds to a Normally Closed input). The go o
only when the controls to which they are associated are operated.
• All the red LEDs must be o (each of them corresponds to a Normally Open input). The light up
only when the controls to which they are associated are operated.

NB: In the latest versions of the control boards, the voltage change
through jumper J7 is no longer necessary (make sure whether it is
present on the control board or not).
ATTENTION: POWERING THE CONTROL UNIT WITH AN EXTERNAL
SOURCE, ALL THE OTHER 18V (24V for MASTER-R) DC OUTPUTS BE-
COME THE SAME AS THE OUTSIDE VOLTAGE.
3 - 6 PEDESTRIAN N.O. input for PEDESTRIAN button - Controls prtial opening and closing (1/3
of the complete journey) and it is subject to the setting of DIP SW 2 and 4.

automation and is regulated based on the function of dip-switches 2 and
4. (4= O/C - 6= COM)
5 - 6 STOP
STOP button N.C. input – Stops the automation in any position, temporarily pre-
venting the automatic closure, if programmed.
(5= STOP - 6= COM )
NOTE: A safety micro-switch is connected to the STOP push-button. In case
the STOP input remains open for more than 5 seconds, the operator will per-
form a cycle at a slow speed to reset the operating parameters to the values
originally saved (see “Restoring automatic operation”). The micro-switch
should be connected in series to further STOP push-buttons where present.
7 - 8 INTERNAL
PHOTOCELLS
PHOTOCELL OR SAFETY DEVICE input INSIDE the gate (Normally Closed
contact). When these devices trigger during the opening phase, they tem-
porarily stop the gate until the obstacle has been removed; during the
closing phase they stop the gate and then totally open it again. Bridge the
connectors if not used.
(7= COM - 8= CLOSE)
7 - 9 EXTERNAL
PHOTOCELLS
PHOTOCELL OR SAFETY DEVICE input OUTSIDE the gate (Normally Closed

Note: the photocell transmitter must always be supplied by terminals
no. 12 and no. 13, since the safety system test (phototest) is carried
out on it. Without this connection, the control unit does not work. To
override the testing of the safety system, or when the photocells are
not used, set dip-switch no. 6 to OFF.
7 - 10 SENSITIVE
EDGE
SAFETY EDGE input (Resistive or xed safety edge). During the opening phase,
it temporarily stops the gate and makes it close again for about 20 cm, thus
allowing to free the potential obstacle.
During the closing phase, it stops the gate and makes it totally reopen at a
limited speed. Jumper terminals if not used.

manouvre, outputs 11-12, 12-13, 14-15, 16-17 and 16-18 will be switched o.
The terminal board for motor 2 (23-24) is to be used in support of the one for motor 1
(MASTER18QR / MASTER-R), or in case of fault/failure of the one for motor 1 (28-32), see
wiring diagram page 2-3.
IMPORTANT:
•do not power up auxiliary relays o other devices through the 18V output (24V for MASTER-R)
DC output (terminals 11 – 12) to avoid malfunctions of the control unit. Use separated power
supply / transformers instead;
•do not connect switching feeders or similar apparatus close to the automation that may be
a source of disturbance.
5. LOGIC ADJUSTMENTS
Make the logic adjustments.
Note: when any adjusting devices (trimmers or dip-switches) on the control panel are operated,
a complete manoeuvre must be carried out in order for the new settings to take eect.
TRIMMER
RALL adjustment of the slowdown duration in both opening and closure of the gate. To
adjust the duration of the slowdown, act on the trimmer as shown in the picture,
only with the gate completely closed and check it by pressing the PROG button. The
gate will open and consequently close immediately to show the setting. In case it
doesn’t go smoothly repeat the procedure with the RALL trimmer and press again
the PROG button for further verication.
NOTE: When storing the TRIMMER RALL stroke, it is recommended to set it to
half the stroke.
FR. obstacle detection sensitivity adjustment.
Note: by rotating the TRIMMER FR. clockwise the sensitivity of the gearmotor
to obstacles diminishes and therefore the thrust force increases; vice-versa, by
rotating it counter-clockwise, the sensitivity of the gearmotor to obstacles
increases and therefore the thrust force diminishes.
T.C.A. Automatic Closing time adjustment: from about 1 to 120 seconds (see dip-switch no. 1);

6. MEMORIZATION PROCEDURE
WARNING: After powering the control panel, wait 2 seconds before you start performing the
adjustment operations.
Note: the mechanical stops of the automation must be regulated both in opening and in closing
[see motor instructions].
When you have completed the installation procedures:
ENGLISH

21
Check the position of dip-switches 9, 10 and 11. Dip-switches must be set according to
the automation model (see table of dip-switches 9-10-11, “Logic adjustments” section).
IMPORTANT: carry out the rst memorization with the RAL trimmer completely turned clockwise
(maximum slowdown) !!
It is recommended to start the learning process with the gate at 0,5 m from closing mechanical stop.
Press without releasing the PROG button till the DL8 LED starts ashing (yellow):
- the automation starts to open slowly looking for the opening limit stop;
If the automation closes instead of opening, stop the run of the gate (by cutting the pho-
tocells or closing the STOP contact), invert the polarity of the motor, take the gate in the
closed position (on the mechanical stop) and restart the procedure from the beginning.
Note: if the automation does not work, check the input connections. The DL6, DL5, DL4 and
DL3 green LEDS must be on.
- once the limit stop is reached, the automation starts closing looking for the closing limit stop (in this
phase the control unit gathers all the parameters regarding the run);
- the automation carries out one complete opening to optimize the opening power;
- after a short pause, the automation carries out one complete closure to optimize the closing power.
WARNING:
- The procedure can be stopped by pressing the STOP button.
- During the various stages of the operation, if the sensor is activated saving is stopped. To
restart the procedure from the beginning (with the DL8 yellow LED ashing), use the AP/CH
control, the remote control (if programmed) or press the PROG button briey.
Please remember that an obstacle during saving is interpreted as a mechanical limit stop
(the system does not start any safety operation, it just stops the motors).
Make sure you don’t stand near the automation during saving.
7. K126MA CHARACTERISTICS
TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening/closing of the automation can be controlled by means of a timer that has a free N.O.
output contact (relay). The timer must be connected to terminals 4 - 6 (OPEN/CLOSE button) and can
be programmed so that, at the desired opening time, the relay contact closes until the desired closing
time (when the timer’s relay contact opens, enabling the automatic closing of the gate).
Note: the automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
BATTERY CHARGER BOARD (INTEGRATED)
If the battery is connected the automation will operate in any case if there is no mains power supply.
If the voltage drops below 11.3 Vdc, the automation ceases to operate (the control unit remains fed);
whereas, when the voltage drops below 10.2 Vdc, the card completely disconnects the battery (the
control panel is no longer fed). During battery operation, LOW CONSUMPTION MODE will be automati-
cally activated. At the end of each maneuver 11-12, 12-13, 14-15, 16-17 and 16-18 will be powered o.
In order to connect the battery to the control board, it is required a specic connector supplied along
with the battery.
Note: when the battery-mode is activated the system switches in low-power mode therefore the
auxiliary outputs (11-12) are disabled. (For use of external receivers, Gsm, etc. connect these in
parallel to the battery).
OBSTACLE DETECTION
If the obstacle detection function (adjustable through FR trimmer) is activated during an opening ma-
noeuvre, the gate closes approx. 20 cm., if it is activated during a closing manoeuvre, the gate opens
all the way .
WARNING: the control panel logics may interpret mechanical friction as an obstacle.

After 5 minutes from the function activation, the board automatically resumes to the standard LED
visualization (to resume manually press simultaneously CH1, PROG and CH2).
10. RESTORING AUTOMATIC OPERATION
Should the Bar need to be operated manually, use the release system. After the manual operation:
• after a Mains Power Failure, such as a black-out (controller remains disconnected for a certain time)
or after a manual release (without power shortage to the controller for more than 5 seconds), the
automation will be moving slowly to allow the Controller to establish its Limits (REALIGNMENT
procedure).
11. 433.92 MHz BUILT-IN RADIO RECEIVER
The radio receiver can learn up to a maximum of 30 codes of rolling code (S2RP, S4RP, K-SLIM-RP, T-4RP)
to be set freely on 3 channels.
The rst channel directly commands the control board for opening the automatic device; the second
channel commands a relay for a N.O. no-voltage output contact (terminals 19 - 20, max. 24V AC, 1 A)
and the third channel controls directly the pedestrian opening from the controller.
LEARNING SYSTEM FOR RADIO CONTROL DEVICES
CH1 = 1st channel (OPEN/CLOSE)
CH2 = 2nd channel
CH3 = 3rd channel (PEDESTRIAN)
1_ Press button CH1 briey to associate a radio control device with the OPEN/CLOSE function;
ENGLISH

25
2_ the (green) DL8 LED is ON to indicate the code learning mode has been activated (if no code is
entered within 10 seconds the board exits the programming function);
3_ press the button of the relative radio control device;
4_ the (green) DL8 LED turns o to indicate saving is complete and then on again immediately wait-
ing for other radio control devices (if this is not the case, try to re-transmit or wait 10 seconds and
restart from point 1);
5_ to memorise codes to other radio control devices, press the key to be stored on other devices
within 2-3 sec. After this time (DL8 LED turns o) must repeat the procedure from point 1 (up to a
maximum of 30 transmitters);
6_ if you wish to save on the 2nd channel, repeat the procedure from point 1 using the CH2 key instead
of CH1 (in this case the DL8 LED is yellow);
7_ to program transmitters into the third channel, repeat procedure from point 1 using CH1 and CH2
buttons at the same time (DL8 will turn on red);
8_ to exit the learning mode without memorising a code, press button CH1 or CH2 briey.
If the maximum number of radio controls is reached (30), the LED DL8 will begin to ash
rapidly for about 3 seconds but without performing memorisation.
REMOTE PROGRAMMING BY MEANS OF T-4RP / K-SLIM-RP / S-2RP / S-4RP (V 4.X)
With the new version of software V 4.X it is possible to carry out the remote self-learning of the new
version of transmitters T-4RP / K-SLIM-RP / S-2RP / S-4RP (V 4.X), that is without pressing the receiver’s
programming buttons.
It will be sucient to have an already programmed transmitter in the receiver in order to start the
procedure of remote programming of the new transmitters. Follow the procedure written on the in-
structions of the transmitter T-4RP / K-SLIM-RP / S-2RP / S-4RP (V 4.X).
CANCELLING CODES FROM RADIO CONTROL DEVICES
1_ Keep button CH1 pressed for 3 seconds in order to cancel all the associated radio control devices;
2_ LED DL8 ashes slowly to indicate that the cancellation mode has been activated;
3_ press button CH1 again for 3 seconds;
4_ LED DL8 turns o for approx. 3 seconds and then remains steady to indicate that the code has been
cancelled;
5_ repeat the procedure from point 1 using button CH2 to cancel all the associated radio control de-
vices;
6_ repeat procedure from point 1 using CH1 and CH2 buttons at the same time to erase all transmit-
ters programmed into the third channel;
7_ to exit the learning mode without memorising a code, press button CH1 or CH2 briey.
MEMORY CAPACITY
The code memory capacity* of the D749MA can be expanded from 30 to 126, 254 or 1022 codes (transmit-
ters) by replacing the memory cards as follows
(plug them onto J3 connector, see wiring diagram)
:
126 codes Art. 250SM126
254 codes Art. 250SM254
1022 codes Art. 250SM1022
* Control units are supplied with a standard built-in 30-code memory. The memory card for enhancing the
code memory capacity must be ordered separately.
To allow the previously stored codes (max. 30) to be moved to the control unit, it is required to install
a memory card, making sure that the control unit is at that time o and that the memory card is brand
new and therefore completely empty.
When the control unit is restarted, the codes will automatically move to the memory card.
Moving the codes from the control unit to the memory card does not work if on the memory card used,
radio control codes have already been stored and the memory card has been subsequently erased.
To insert new radio controls, the operation described above shall be repeated.
WARNING: Control unit must be turned OFF to insert / remove a memory card.
RADIO MEMORY RESET:
- press without releasing keys CH1 and PROG till LEDs DL7 and DL8 start ashing quickly with a yellow
light. At this point release the keys and press them again till the LEDs go o conrming the operation

is complete (if they are not pressed the board reverts to normal operation after about 12 seconds).
HARD RESET (factory setting):
- press without releasing keys CH2 and PROG till LEDs DL7 and DL8 start ashing quickly with a red
light. At this point release the keys and press them again till the LEDs go o (reset in progress),
conrming the operation is complete (if they are not pressed the board reverts to normal operation
after about 12 seconds); When the unit starts again saving will be required.
In case of Hard Reset the memory of the radio receiver will not be erased: all existing
transmitters remain programmed.
12. MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
The automation does not start
a- Check there is 230V AC power supply with the multimeter.
b- Check, in the standard mode, that the NC contacts on the board are really normally closed (4
green LEDs on).
c- Set dip-switch 6 (phototest) OFF.
d- Increase the FR trimmer to the limit.
e- Check that the fuses are intact with the multimeter.
The radio control has very little range
a- Check that the ground and the aerial signal connections have not been inverted.
b- Do not make joints to increase the length of the aerial wire.
c- Do not install the aerial in a low position or behind walls or pillars.
d- Check the state of the radio control batteries.
The gate opens the wrong way
Invert the motor connections on the terminal block, terminals 28 - 29 and terminals 23 - 24 (if
used).
