There is no memorised opening
angle
Indicates that the opening angle
learning phase is in progress
Action
Check that the unit is powered; check that the fuses have not been
activated; if this is the case check the cause of the fault and replace
them with other fuses with the same characteristics.
There is a serious fault; switch off the control unit for a few seconds;
if the status persists there is a fault and the electronic board must be
replaced.
Control unit works correctly.
A variation to the status of the inputs: SbS, STOP, activation of the
photocells, or when the radio transmitter is used, is normal.
An overload has been detected therefore the power to the BUS
switched off. Check by disconnecting the devices one at a time. To
restore power to the BUS simply send a command, for example with a
radio transmitter.
Action
Check the devices connected to the STOP input.
STOP input active.
Action
SbS input not active.
This is normal only if the device connected to the SbS input is
active.
Action
No memorisation underway.
This is normal during memorisation mode 1 which lasts maximum
10 s.
This is normal during memorisation mode 2 which lasts maximum
10 s.
Command received from a transmitter which is not memorised.
All devices successfully memorised.
All radio transmitters successfully deleted.
Action
"Slow" speed selected.
"Fast" speed selected.
Some faulty devices may be present; check and if necessary repeat
the device learning phase (see paragraph A.10).
It shows that the search for connected devices is underway (it lasts
maximum a few seconds).
Action
Operation with "half cycle" (semi-automatic).
Operation with "complete cycle" (automatic).
Perform the leaf opening and closing learning phase (read paragraph
7.2).
Indicates that the opening angle learning phase is in progress.
