Deleting all the Radio Transmitters
With this operation all the memorized transmitters are deleted.
1 Press the P1 button [B] on the control unit and hold it down.
2 Wait until the P1 LED [A] lights up, then wait until it goes off, than wait
until it has flashed 3 times.
3 Release the P1 button precisely upon the third flash.
4 Wait approximately 4s for the deletion process to be completed; during
this time the LED will flash very quickly.
If the procedure is successful, after a few moments the "P1" LED will
flash slowly 5 times.

Troubleshooting
The following table contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure.
Table 12
Symptoms
Probable cause and possible solution
The radio transmitter does not emit any
signal (the LED [A] does not light up)
• Check to see if the batteries are exhausted, if necessary replace them (page 34)
The manoeuvre does not start and the
"ECSBbus" LED [B] does not flash
• Make sure that the power cord is properly plugged into the mains outlet
• Check to see if the fuses [E] or [F] are blown; if necessary, identify the reason for the failure and then replace
the fuses with others having the same current rating and characteristics..
The manoeuvre does not start and the
flashing light is off
• Make sure that the command is actually received. If the command reaches the OPEN input, the
corresponding "OPEN" LED [D] must light up; if you are using the radio transmitter, the "ECSBus" LED must
make two long flashes.
The manoeuvre does not start and the
flashing light flashes a few times
• Make sure that the STOP input is active, i.e. that the "STOP" LED [C] comes on. If this does not happen,
check the devices connected to the STOP input.·
• The photocell test which is performed at the starting of each manoeuvre is not successful; check the
photocells, also according to Table 13 on page 24.
The manoeuvre starts but it is immediately
followed by a reverse run
• The selected force is too low to move the leaves. Check to see whether there are any obstacles; if
necessary increase the force as described on page 19.
The manoeuvre is carried out but the
flashing light does not work
• Make sure that there is voltage on the flashing light's FLASH terminal during the manoeuvre (being
intermittent, the voltage value is not important: approximately 10-30Vac); if there is voltage, the problem is
due to the lamp; in this case replace the lamp with one having the same characteristics.

Deleting a Radio Transmitter
If a radio transmitter is available, this operation allows you to delete it.
If the transmitter is memorized in Mode 1, a single deletion stage is
sufficient: just press any button at point 3. If the transmitter is memorized
in Mode 2, one deletion stage is needed for each memorized button.
1 Press and hold down button P1 [B] (Figure 67) on the control unit.
2 Wait until the P1 LED [A] lights up, then, within three seconds:
3 Press and hold down for at least three seconds the button of the radio
transmitter to be deleted.If the radio transmitter has been deleted, the P1
LED will flash quickly five times. If the LED flashes slowly just once, it
means that the deletion has not taken place because the transmitter is
not memorized
4 If there are more transmitters to be deleted, repeat step 3 within ten
seconds while pressing button P1, otherwise the deletion stage will
terminate automatically.
