9.1 - Fault log list
ROBUS can display any faults that have occurred in the last 8 manoeuvres, for example interruption of a manoeuvre due to activation of a pho-
tocell or sensitive edge. To check the list of faults proceed as shown in Table 17.
Table 17 - Fault log Example
01.
Press and hold the [■/Set] key for roughly 3 seconds
3s
02.
Release the [■/Set] key when LED L1 starts ashing
L1
03.
Press and release the [▲] or [▼] keys to shift LED ashing on L8, namely the “input LED”
associated with the “Fault log” parameter
or
L8
04.
Press and hold the [■/Set] key, which must be kept pressed throughout all steps 5 and 6
05.
Wait approx. 3 seconds after which the LEDs corresponding to the faulty manoeuvres will light
up. LED L1 indicates the result of the last manoeuvre and LED L8 indicates the result of the 8th
manoeuvre. If the LED is on, this means that faults occurred during the manoeuvre; if the LED is off,
this means that no fault occurred during the manoeuvre
3s
06.
Press and release the [▲] and [▼] keys to select the desired manoeuvre:
The corresponding LED emits a number of ashes equal to those normally emitted by the ashing
light after a fault (see Table 18)
and
07.
Release [■/Set]
9.2 - Diagnostics and signals
Certain devices directly provide special signals that help to describe the operating status or any malfunction.
9.2.1 - Flashing light signals
During the manoeuvre the FLASH ashing light ashes once every second. When a fault occurs, the ashes become more frequent; the light
ashes twice with a one-second pause between ashes.
Table 18
Signal Cause Solution
1 ash
1-sec pause
1 ash
Bluebus system error At the start of the manoeuvre, the devices connected to BLUEBUS do not correspond
to those memorised during the recognition phase. One or more devices may be faulty;
check and, if necessary, replace them; in case of modications the recognition pro-
cess must be repeated
2 ashes
1-sec pause
2 ashes
Intervention of a photocell At the start of the manoeuvre, one or more photocells prevent movement; verify
whether there are any obstacles.
This is normal when there is an obstacle hampering the gate’s movement
3 ashes
1-sec pause
3 ashes
Activation of the “Motor Force”
limiting device
During the movement, the gate experienced excessive friction; identify the cause
4 ashes
1-sec pause
4 ashes
Intervention of the STOP input At the start of the manoeuvre or during the movement, the STOP input intervened;
identify the cause
5 ashes
1-sec pause
5 ashes
Error in the internal parameters of
the control unit
Wait at least 30 seconds then try giving a command; if the condition persists it means
there is a serious malfunction and the electronic board must be replaced
6 ashes
1-sec pause
6 ashes
The maximum manoeuvre limit/
hour has been exceeded
Wait a few minutes until the manoeuvre limiting device drops below the maximum limit
7 ashes
1-sec pause
7 ashes
Error in the internal electric circuits
Disconnect all power circuits for a few seconds then try to give a command again. If
the condition persists it means there is a serious malfunction and the electronic board
must be replaced
8 ashes
1-sec pause
8 ashes
A command that does not allow
other commands to be executed is
already present
Check the type of command that is always present; for example, it could be a com-
mand from a timer on the “open” input
