8 3 SIGNALS ON THE CONTROL UNIT
The control unit has LEDs 'L1-L4' located on the keys ("Figure 53").
Each of these LEDs can emit specific signals, both during normal op-
eration and in the event of a fault. The cause and possible solution for
each type of fault are described in "Table 19 .

Possible solution
Check for the presence of power; check that the fuses are not blown; if necessary,
identify the cause of the fault then replace them with fuses having the same
specifications.
There is a serious anomaly; try switching off the control unit for a few seconds; if the
condition persists, it means that there is a fault and the electronic circuit board must
be replaced.
Normal control unit operation.
This is normal when there is a change in one of the inputs: SBS, STOP, OPEN,
CLOSE, the photocells intervene or the radio transmitter is used.
Everything is normal; when the control unit receives a command, it resumes normal
operation (after a short delay).
Refer to the information in 'Table 18'.
To activate the ECSbus power supply, simply give a command (e.g. with the
transmitter).
STOP input active.
SbS input not active.
This is normal if the device connected to the SbS input is actually active.
OPEN input not active.
No storage in progress.
This is normal during storage in Mode 1, which lasts for a maximum of 10 seconds.
This is normal during storage in Mode 2, which lasts for a maximum of 10 seconds.
Deletion of a transmitter successful.
Memory successful.
Deletion of all transmitters successful.
'Slow' speed selected.
'Fast' speed selected.
Perform the position learning phase again (see chapter Storing connected
devices).
Indicates that the search for connected devices is in progress (lasts a few seconds
at most).
