7.7.2) Signals on the control unit
On the RUN control unit there is a set of LED's each of which can
give special indications both during normal operation and in case of
malfunctions.
Table 22: LED's on the control unit's terminals
Fault
Make sure there is power supply; check to see if the fuses are blown; if necessary, identify
the reason for the failure and then replace the fuses with others of the same characteristics
On
Serious fault
There is a serious malfunction; try switching off the control unit for a few seconds; if the con-
dition persists it means there is a malfunction and the electronic board has to be replaced
One flash every second
All OK

2 quick flashes
Input status variation occurred
This is normal when there is a change in one of the inputs: STEP-BY-STEP, STOP,
OPEN, CLOSE, triggering of photocells or the radio transmitter is used
Series of flashes separated by
a one second pause

At the start of the manoeuvre, the devices connected to BLUEBUS do not cor-
respond to those recognized during the self-learning phase. One or more
devices may be faulty; check and, if necessary, replace them; in case of modifi-
cations repeat the self-learning process (7.3.4 Self-learning Other Devices).
7.7.1) Flashing light signalling
During the manoeuvre the flashing light FLASH flashes once every second. When something is wrong the flashes are more frequent; the light
flashes twice with a pause of a second between flashes.

Activation of a photocell
At the start of the manoeuvre, one or more photocells do not enable it; check to
see if there are any obstacles.
This is normal when there is an obstacle impeding the movement.

Error in parameters in
electronic control unit
Wait at least 30 seconds, then try giving a command. if the condition persists it
means there is a malfunction and the electronic board has to be replaced
Maximum limit of manoeu-
vres per hour exceeded
Wait for a few minutes until the manoeuvre limiting device falls to below the max-
imum limit

Error in internal electrical
circuits
A command is already pre-
sent that disables execution
of other commands
Disconnect all the power circuits for a few seconds and then try to give the com-
mand again. if the condition persists it means there is a serious malfunction and
the electronic board has to be replaced
Check the type of command that is always present; for example, it could be a
command from a timer on the “open” input.
