Slow flashing
Rapid flashing
Very rapid flashing
Action
Perform quick commissioning of the
drive.
Wait until programming is complete
Switch the power supply off, wait about
5 min. then switch the power supply
back on.
Contact Somfy technical assistance.
Once detection is complete, the indica-
tor light goes out.
Once the auto-test is complete, the indica-
tor light goes out.
Check the alignment and wiring of the
cells
A er 3 mins, the wired control input
(terminals 12 and 13) allows the door to
be controlled in dead-man mode.
If when confirming P4=2 (BUS cells),
the P4 and photoelectric cells indicator
lights are flashing, there is a short-cir-
cuit on the cells safety input, and the
parameter modification is disregard-
ed. Check that the bridge between
terminals 17 and 18 has been removed,
and check the connection of the cells
(see 6.2.1 Photoelectric cells - Fig.
22). Set up P4 again, and then perform
auto-programming again.
Once detection is complete (gate open),
the indicator light goes out.
Once the auto-test is complete, the indica-
tor light goes out.
Check the closure of the gate and the
gate contact wiring.

12.3. Safety devices failure

In the event of a photoelectric cells failure, a key contact connected
between terminals 12 and 13 enables the door to be controlled in dead-
man mode a er 3 minutes.
Mechanically check that the control
point is not blocked. If the control point
is not blocked, disconnect the control
point. If the indicator light goes out,
check the wiring.
Check the operation and wiring of the
connected peripherals.
If the indicator lights are still flashing,
cut the power supply, remove the green
terminal block, wait 30 s and then
switch the power supply back on: if all
4 indicator lights stop flashing, check
the wiring of the cells and peripherals
connected to the wired inputs.
If the indicator lights are still flashing,
cut the power supply, remove the black
terminal block (7-8-9), wait 30 s and
then switch the power supply back on: if
all 4 indicator lights stop flashing, check
the wiring of all peripherals connected
to this power supply.
If the indicator lights are still flashing,
cut the power supply, remove the
orange terminal block (5-6), wait 30 s
and then switch the power supply back
on: if all 4 indicator lights stop flashing,
check the wiring of the orange light,
and then refit the terminal block. Start
a movement to make sure there is no
short-circuit.
If all 4 indicator lights continue to flash,
contact Somfy technical assistance.
If all the parameter setting indicator
lights flash when a programming button
is pressed, the keypad is locked. Unlock
it (see chapter 11 Locking the program-
ming buttons - Fig. 39)
• Check if the remote control button has
been programmed.
• Check that the remote control is
equipped with io-homecontrol radio
technology.
• Check the remote control batteries.
• Check the other indicator lights to see
if there is another fault.
• The control is not operational from this
position.
• The button is memorised for function
other than opening/closing the garage
door (for example controlling the
auxiliary output)
