•TIP – You need solid opening and closing stops. The control board will search for these when
programming. Make sure they have no movement or flex.
•TIP– You need to fit three small loops of wire to your safety inputs to make anything work. These
can be removed later if you install safety devices to these input terminals. But for now, take three
pieces of light gauge wire (speaker or telephone wire is good) about 50mm long and strip both ends
7mm and insert them as above from 7 to 8, 7 to 9 and 7 to 10.
•TIP – The STOP input will not seal unless you have the manual override handle closed.
•TIP – To program and to run all safety inputs need to be sealed. The LED lights 5,6,7 and 8 should all
be lit green.
•TIP – Start with all dip switches in the off position. You can adjust these to suit later.
•TIP – Do not install any accessories until after you have programmed the unit and have it operating
as you would like. You can then add each accessory one at a time.
•TIP – If using solar power refer to the manual for correct input power connection. Also get hold of a
copy of the solar power tips n tricks.
QUICKSTART
1. Ensure you have followed the instructions above and that you have the four green LED lights lit.
2. Carefully turn trimmer V-RAL anti clockwise until it comes to a stop. (Do nor force)
3. Release the gate and position it 500mm from the fully open stop.
4. Press the PROG button and hold until DL2 LED starts flashing orange. Release the button.
5. The gate should start to open slowly to find the open stop. If the gate closes instead remove power,
change the polarity of the motor by swapping terminals 23 and 24 and start again from point 3.
6. When the opening stop is found the gate will close slowly searching for the closing stop.
7. When the closing stop is found the gate will complete a full open and close before exiting program
mode of working times.
8. If using remote controls press and release quickly CH1. Green LED2 should light to indicate ready.
9. In the next ten seconds press for one second and release one of the buttons on your remote
control. The green LED turns off and on again waiting for further remote controls.
10. When you have programmed all remote controls simply wait ten seconds until DL2 goes out.
11. Test your install.
12. You can now make adjustments and connect accessories one at a time and test each time.

WARNINGS
This manual is designed to assist qualied installation personnel only. It contains no information that may
be of interest to nal users. This manual is enclosed with control unit and may therefore not be used for
dierent products!
Important warnings:
Disconnect the mains power supply to the board before accessing it.
The 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 qualied 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 qualied 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.
Unqualied 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. Check that the gate
slides freely on a horizontal plane (gates that open / close on sloping oors can aect the operation
and duration of the control unit and the gearmotor).
Then make sure that the power consumption of the gear motor is not greater than 3A (other-
wise the control panel may not work properly). Havig followed the previous points, now make
sure the motor has a proper absorption.
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.

- 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 K128MA board has two working modes, selectable through the J6 jumper (see wiring diagram).
J6 Not jumped: standard mode, i.e. the control unit is powered all the time;
J6 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). In
this way, the DL1 and DL2 LEDs ash every 4 seconds.
Once the connection is achieved, in low-energy mode, press the PROG button briey:
• 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.

Termi-
nals Function Description
FS1 - FS2 POWER SUPPLY
Board supply input 13,5 V AC – Powered by the toroidal transformer housed
and protected by a fuse (F 6,3A) on the 230 V AC power supply.
For low power connection:
First connect the power supply given by the transformer and
then by the battery (terminals 1-2)
1 - 2 EXTERNAL
POWER External power input (ex. Photovoltaic system 12V DC or battery 12V DC).
Notice: battery charger board not integrated.
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.
(3= PED - 6= COM)
4 - 6 OPEN/CLOSE OPEN/CLOSE button N.O. input – Controls the opening and closing of the automation and is regulated based on the function of dip-switches 2 and
4. (4= O/C - 6= COM)
ENGLISH

20
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 con-
tact). When these devices trigger during the opening phase, they temporarily
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
contact). Then these devices trigger during the closing phase, they stop the
gate and then totally open it again. Bridge the connectors if not used. (7=
COM - 9= FOT)
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 sensitive edge 8,2 KΩ or with n.c. contact - see
DIP SWITCH 12 ).It works during the opening phase and also during the closing
phase, resulting in the temporary stop of the automation and:
- the partial inversion of its movement for 20 cm (only in the opening phase)
- the complete opening (only in the closing phase);
thus freeing any obstacle. NOTE: if a resistive sensitive edge 8,2 KΩ is con-
nected, set dip-switch no. 12 to ON;
If a xed safety edge with NC contact is connected, set dip-switch no.
12 to OFF;
Jumper terminals if not used. (7= COMMON - 10= SENSITIVE EDGE)
11 - 12 PHOTOCELLS output 18 V DC max. 15 W per photocells (TX/RX) and auxiliaries
(11 = NEGATIVE - 12 = POSITIVE)

the end of each manouvre, outputs 11-12, 12-13, 14-15, 16-17 and 16-18
will be switched o.
IMPORTANT:
• do not power up auxiliary relays o other devices through the 18V 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 eect.
TRIMMER
V-RAL adjusts the automation deceleration speed during the nal section of the stroke;
Note: When memorizing the stroke, set the TRIMMER RALL fully turned coun-
terclockwise (minimum deceleration speed).
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.
Beyond a certain threshold, the TRIMMER FR inhibits the detection of obstacles.
This is signaled during the maneuvers by 7 orange ashes of the DL2
T.C.A. Automatic Closing time adjustment: from about 1 to 120 seconds (see dip-switch no. 1);

- HOW TO CHANGE THE DECELERATION POINTS
If you want to change the deceleration start points, just press again the PROG key briey (1 sec.) and the
automation will start to open again and will allow you to insert the new deceleration point in opening
and closing by pressing the PROG key again in the desired points.
WARNING:
• During the memorization, the intervention of the safety devices (photocells, sensitive edge
or stop input) stop the automation and pause the procedure itself; to resume, it will be
necessary to press only and exclusively the PROG button.
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 motor)

7. K128MA 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).
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.
8. LED DI DIAGNOSI

DL8 - Green SENSITIVE EDGE LED signal
Multiple errors are signalled by a 2-second pause between signals.
Should the encoder (obstacle detection) activates while closing, the controller will reverse the direction
and slowly open until the laef reaches its fully opened position. Auto Close function will be deactivated
until a further command pulse is given. In case of 5 consecutive safety interventions the controller will
progressively increase the Auto Close delay. Once the closing has been succesfully achieved, the Auto
Close delay will go back to standard setting.
*LED ENCODER:
E1 - Red ENCODER OPERATION signaling LED. During the gate stroke, the LED ashes red.
The ashing varies according to the motor speed.
OPTIONAL LIMIT SWITCH LEDS:
The LEDs are steady on as long as the gate is moving, while one of the two LEDs switches o when:
LFCA - o the LED signals the arrival at the opening limit switch
LFCC - o the LED signals the arrival at the closing limit switch
9. 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).
10. 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 CH1+ CH2= 3rd channel CH3 (PEDESTRIAN)
1_ Press button CH1 briey to associate a radio control device with the OPEN/CLOSE function;
2_ the (green) DL2 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) DL2 LED turns o to indicate saving is complete and then on again immediately waiting
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 (DL2 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 DL2 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 (DL2 will turn on red);
8_ to exit the learning mode without memorising a code, press button CH1 or CH2 briey.
If the maximum number of radio controls is reached (30), the LED DL2 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 sucient 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
instructions 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 DL2 ashes slowly to indicate that the cancellation mode has been activated;
3_ press button CH1 again for 3 seconds;
4_ LED DL2 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
devices;
6_ repeat procedure from point 1 using CH1 and CH2 buttons at the same time to erase all transmitters
programmed into the third channel;
7_ to exit the learning mode without memorising a code, press button CH1 or CH2 briey.
MEMORY CAPACITY
The code memory capacity* can be expanded from 30 to 126, 254 or 1022 codes (transmitters) by replac-
ing 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:
- keep the CH1 and PROG keys pressed until the green DL1 and orange DL2 leds start ashing rap-
idly. At this point, release the keys and press them again until the LEDs go o, conrming that the
operation is complete (if they are not pressed and you wait, the board returns to normal operation
after about 12 seconds).
HARD RESET (factory setting):
- Keep the CH2 and PROG keys pressed until the green DL1 and the red DL2 LEDs start ashing quickly.
At this point, release the keys and press them again until the DL1, DL2 and DL8 LEDs switch o.
Release the keys; all the LEDs will turn o conrming that the operation is complete. After about
5 seconds the DL2 will start ashing red/green.
If they are not pressed and you wait, the control unit returns to normal operation after 12 seconds.
Upon restarting, it will be necessary to carry out the memorization procedure.
In case of Hard Reset the memory of the radio receiver will not be erased: all existing
transmitters remain programmed.

11. SET-UP FOR OPERATION WITH TAU APPS
In order to use the TauApp and TauOpen apps, it will be necessary to connect to input J4 of the control
unit using the supplied cable, the respective T-WIFI and T-CONNECT devices. To activate the operation
of the apps see the respective instructions.
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).
Inability to memorize a new remote control
a- Reset the radio memory (paragraph 10).
b- Check that the new and old remote control use the same technology.
