9.6.2 - Flashing indicator
During the manoeuvre the flashing indicator flashes once every second.
When something is wrong the flashes are more frequent (every half sec-
ond); the light flashes twice with a second’s pause between flashes, see
Table 12.
9.6.3 - Control unit
The control unit has a series of LEDs, each of which can give particular
signals both during regular operation and when there is a problem, see
Table 13.
TABLE 13 (fig. 44)
ECSbus LED [A] Status Action
Off Malfunction Make sure there is power supply; check to see if the fuses are blown; if nec-
essary, identify the reason for the failure and then replace them with others of
the same type
On Serious malfunction There is a serious malfunction; try switching off the control unit for a few sec-
onds; if the condition persists, it means there is a malfunction and the circuit
board has to be replaced.
One flash every second All OK Normal operation of control unit.
2 long flashes The status of the inputs has
changed
This is normal when there is a change in one of the inputs: SbS, STOP, trig-
gering of photocells or the radio transmitter is used

TABLE 11
“SAFE” Led (fig. 8-E) Status Action
Off The photocell has no power supply
or is faulty
Check that on the terminals of the photocell there is a voltage of approximately
8-12 Vdc; if the voltage is correct, it is likely that the photocell is faulty.
3 quick flashes and 1
second pause
Device not recognised by control
unit
Repeat the recognition procedure on the control unit. Check that all photocell
pairs on the ECSbus have different addresses (see Table 8)
1 very slow flash The RX is receiving optimum signal Normal operation
1 slow flash The RX is receiving good signal Normal operation
1 quick flash The RX is receiving poor signal Normal operation but it is necessary to check the TX-RX alignment and correct
cleaning of the glasses
1 very quick flash The RX is receiving bad signal It is at the limit of normal operation. It is necessary to check the TX-RX alignment
and correct cleaning of the glasses
Always on The RX is receiving no signal Check for any obstruction between TX and RX. Check that the LED on TX emits
a slow flashing. Check the TX-RX alignment

Error on ECSbus At the beginning of the manoeuvre, the verification of the devices present does
not correspond to those learned; check and possibly try to redo the learning
(9.3.3 “Recognition of other devices” ).
Some faulty devices may be present; check and replace them.
2 flashes
1 second pause
2 flashes
Triggering of a photocell At the start of the manoeuvre, one or more photocells are preventing movement;
check to see if there are any obstacles.
During the movement, although the obstacle is effectively present, no action is
required.
3 flashes
1 second pause
3 flashes
Action of the “motor force” limiting
device
During the movement, the gate experienced excessive friction; identify the cause.
4 flashes
1 second pause
4 flashes
Activation of the STOP input At the start of or during the manoeuvre, the STOP input was activated; identify
the cause.
