door travel, check motor absorption under no load and applied on the
door;
• 5 flashes: no encoder signal;
check wiring, check encoder, check that the motor rotates freely when
powered directly by battery, check fuse F1;
• 6 flashes: presence of obstacle;
Ensure absence of obstacles along door travel and smooth movement
of the door;
• 7 flashes: no memorisation procedure performed;
Perform memorisation procedure.
• 8 flashes: no motor signal;
check wiring, check that the motor rotates freely when powered directly
by battery, check fuse F1;
Multiple error signals are indicated with a pause of 2 seconds between
one signal and the next. The error signals persist until a complete auto-
mation manoeuvre is performed (opening and closing).
If an obstacle is detected while closing, the control unit reverses the
movement and switches to slow mode as it searches for the closing
travel limit. To reset the automation must complete the opening cy-
cle, if not, every time the safety device is activated the automation will
search for the travel limit.
If the obstacle is detected during a timed opening, a manual command
via remote control (CH1) or buttons, O/C or ENTER is required to restart
the automation.
BATTERY CHARGE CARD (BUILT-IN)
If the battery is connected, the automation will be operative also in the
event of a power failure. If voltage falls below 11.3 Vdc, the automa-
tion stops operating (the control panel remains powered); if it falls be-
low 10.2 Vdc, the card disconnects the battery completely (the control
panel is no longer powered).
OBSTACLE DETECTION
The obstacle detection function (settable via the trimmer FR), if acti-
vated during the opening phase, re-closes the door by approx. 20 cm,
and during closing activates a complete opening cycle.
IMPORTANT: the control panel logic may interpret mechanical fric-
tion as an obstacle.
N.B. the O/C button on the card has the same function as the
OPEN/CLOSE key.
4.8_ Advanced functions
Clock function: a timer may be used (e.g. weekly), connected to the
input of the open-close button, to keep the door open in set time inter-
vals, to then enable automatic re-closure.
N.B. the door remains open while the Op/Cl input is engaged.
Open only" function: by setting dipswitch 1 to ON and dipswitch 4 to
OFF, the Op/Cl input will only operate as an opening command, while
the door will close exclusively after the set interval for automatic clo-
sure.
4.9_ Built-in 433.92 MHz radio receiver
The radio receiver can learn up to max. 30 codes in rolling codes (BU-
G2R, BUG4R, K-SLIM-RP, T-4RP) set as required.
RADIO CONTROL LEARNING
1_ briefly press the key RADIO to associate a radio control with the
function OPEN/CLOSE;
2_ led DL3 turns off to indicate code learning mode (if no code is en-
tered within 10 seconds, the card exits programming mode);
3_ press the key of the radio control to be used;
4_ led DL3 turns on again to confirm memorisation (if this does not
occur, wait 10 seconds and repeat the steps from point 1);
5_ to memorise other radio controls, repeat the procedure from point
1, for up to a maximum of 30 transmitters.
6_ to exit learning mode without memorising a code, briefly press the
key RADIO.
N.B.: if the maximum number of radio controls is reached (30),
led DL3 flashes quickly for approx. 3 seconds, without per-
forming memorisation.
REMOTE PROGRAMMING VIA T-4RP, K-SLIM-RP and BUG-R
It is also possible to learn the new versions of the radio controls T-4RP,
K-SLIM-RP and BUG-R remotely, i.e. without acting directly on the re-
ceiver programming keys.
A radio control previously programmed on the receiver is all that is
needed to open the remote programming procedure for new radio
controls, programmed via TAUPROG.
Activation of self-learning mode of the control unit and memorisa-
tion of the new radio control.
This operation enables memorisation of the new radio control code on the
control unit, but an operational "RP" radio control must already be avail-
able. The subsequent operations must be performed in the vicinity of the
system control unit. Activation of self-learning mode on the control unit
and memorisation of the new radio control:
1 On the operative (old) radio control, press and hold the key for
channel 1, and press the channel 2 key three times.
2 Release the keys. The radio control led starts flashing to indicate
that the self-learning mode is enabled.
3 Still on the operative (old) radio control, press the key currently
used to activate the automation for at least 3 seconds.
4 At this point the control unit confirms changeover to program-
ming mode by activating the flashing light (except for external
receivers in the RXDC series).
5 Press the radio control key to be memorised again. If program-
ming is successful, the control unit flashing light turns off.
DELETING RADIO CONTROLS
1_ press and hold the RADIO key for approx. 3 seconds to delete all
associated radio controls;
2_ led DL3 starts flashing slowly to indicate that deletion mode is ena-
bled;
3_ release the RADIO key and press again for 3 seconds;
4_ led DL3 turns off for approx. 3 seconds, and then remains lit to
confirm deletion;
5_ to exit deletion mode, briefly press the RADIO key.
5_ MANUAL RELEASE
If manual movement of the door is necessary, due to a power failure
or problem with the automation, the release device is used as follows:
1_ In the case of the traditional release system, pull the knob down-
wards as shown in fig. 31.
2_ In the case of external release (8 fig. 3), turn the handle.
3_ Manually open or close the door.
6_ RESTORING NORMAL OPERATION
To restore normal automation operation, return the door to the initial
position when you hear the carriage re-engage.
Caution: if you do not hear the carriage re-engage (when the initial
position is with the door closed), activate the operator (via radio
control, key-operated selector switch etc.); a number of complete
manoeuvres are required to repeat automatic self-learning of the
travel limits.
7_ FINAL CHECKS AND START-UP
I
mmediately after powering up T-SKY, perform a number of simple
checks:
- Ensure that the motor does not activate any door movement and
that the courtesy light is off.
If this is not so, disconnect the control unit from the power supply im-
mediately and check the electrical connections carefully.
Other useful information for troubleshooting can be found in chapter
12 "Troubleshooting".
8_ TESTING AND COMMISSIONING
This is the most important phase of automation set-up to ensure maxi-
mum system safety.
The test can also be performed as a periodic check of automation de-
vices.
Testing of the entire system must be performed by skilled
and qualified personnel, who are responsible for the tests
required to verify the solutions adopted according to the
risks present, and for ensuring observance of all legal pro-
visions, standards and regulations, with particular refer-
ence to all requirements of the standard EN12445 which
establishes the test methods for testing automations for
power-operated gates and doors.
