11 DIAGNOSTIC AND TROUBLESHOOTING

11.1 Indicator light status

Off

Slow flashing

Permanently lit

Rapid flashing

Very rapid flashing

11.2 Diagnostic

SET indicator light

The first time the unit is powered on, programming is not carried

out
→ Perform quick commissioning of the motorisation.
Programming in progress

Electronic fault
Motor thermal cut-out
→ Switch the power supply off, wait about 5 min. then switch the

power supply back on.
Programming complete

Photoelectric cells indicator light

Normal operation

• Detection in progress

→ Once detection is complete, the indicator light goes out.

• Permanent fault

→ Check the alignment and wiring of the cells.

NOTICE! After 3 mins, the wired control input (terminals 12 and

13) allows the door to be controlled in dead-man mode.

Auto-test in progress
→ Once the auto-test is complete, the indicator light goes out.

Photoelectric cells indicator light + P4 indicator light

Short-circuit at cells safety input
→ If, when confirming P4=2 (BUS cells), the P4 and photoelectric

cells indicator lights are flashing, there is a short-circuit on the

cells safety input, and the parameter modification is disregarded.

Check that the bridge between terminals 17 and 18 has been

removed, and check the connection of the cells (see

). Set up P4 again, and then perform auto-

programming again.

Gate contact indicator light

Normal operation

• Detection in progress

→ Once detection is complete, the indicator light goes out.

• Permanent fault

→ Check the closure of the gate and the gate contact wiring.

Auto-test in progress
→ Once the auto-test is complete, the indicator light goes out.

Wired control indicator light

Normal operation
Control activated
→ 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.

Indicator lights (15 to 18)

Short circuit on connected peripherals wired input
→ 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.

Parameter setting indicator lights

Locking/unlocking the programming buttons
→ If all the indicator lights flash when a programming button is

pressed, the keypad is locked. Unlock it, see

Locking the

programming buttons [

p.22]

PROG indicator light

No radio reception when a button is pressed on the remote

control
→ 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.
Radio control received but no action by the actuator
→ 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 a function other than opening/

closing the door (for example controlling the auxiliary output).
→ Check that the "SET" indicator light is lit constantly to ensure

that the programming has been carried out.

11.3 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

after 3 minutes.

11.4 Set&Go settings

CAUTION
Additional settings may have been made using the Set&Go tool, and are not

accessible with the motor interface (see
