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.
ECSbus LED [A] Status
Off Malfunction
On Serious malfunction
One flash every second All OK
2 long flashes The status of the inputs has
changed
TABLE 11
Action
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.
Repeat the recognition procedure on the control unit. Check that all photocell
pairs on the ECSbus have different addresses (see Table 8)
Normal operation
Normal operation
Normal operation but it is necessary to check the TX-RX alignment and correct
cleaning of the glasses
It is at the limit of normal operation. It is necessary to check the TX-RX alignment
and correct cleaning of the glasses
Check for any obstruction between TX and RX. Check that the LED on TX emits
a slow flashing. Check the TX-RX alignment
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.
TABLE 12
Action
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.
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.
During the movement, the gate experienced excessive friction; identify the cause.
At the start of or during the manoeuvre, the STOP input was activated; identify
the cause.

TABLE 13 (fig. 44)
Action
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
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.
Normal operation of control unit.
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
