9.8 - DIAGNOSTICS AND DEVICE SIGNALS

Certain devices are configured to display messages to identify their operating status or any anomalies.

9.8.1 - Photocell signals

The photocells contain a SAFE led (Fig. 32) that allows for verifying their operating status at any time: see
Table 8.

The photocell is not powered or is

unit
1 very slow flash The RX receives an excellent signal
1 slow flash The RX receives a good signal
1 quick flash The RX receives a poor signal
1 very quick flash The RX receives a bad signal
Always lit The RX does not receive any signal

9.8.2 - Flashing light signals

During the manoeuvre, the flashing light emits 1 flash each second; when there is an anomaly, it flashes quickly: see Table 9.

4 flashes Intervention of the Stop input

9.8.3 - Control unit signals

On the control unit there are LEDs (Fig. 8) that emit signals both during normal operation and in case of anomalies: see Table 10.

TABLE 8
Action
Check that the voltage on the photocell terminals is around 8–12 VDC; if the volt-
age is correct, the photocell is probably faulty
Repeat the recognition procedure on the control unit. Check that all pairs of pho-
tocells on the ECSbus have different addresses (consult the instruction manual of
the photocells)
Normal operation
Normal operation
Normal operation but check TX-RX alignment and correct cleaning of photocell
lenses
At the limit of normal operation; check TX-RX alignment and correct cleaning of
photocell lenses
Check for any obstruction between TX and RX. Check that the led on TX emits a
slow flash. Check the TX-RX alignment
TABLE 9
Action
At the beginning of the manoeuvre the devices present do not match those recog-
nised; check and, if necessary, try running the recognition procedure (Par. 9.2.1).
One or more devices may be faulty; check and, if necessary, replace them
At the start of the manoeuvre, one or more photocells do not enable movement;
check to see if there are any obstructions.
During the movement, if the obstacle is effectively present, no action is required
During the movement, the gate experienced excessive friction; identify the cause
At the start of the manoeuvre or during the movement, the Stop input intervened;
identify the cause
TABLE 10
Action
Verify whether there is power and whether the fuses are blown; in this case, iden-
tify the reason for the failure then replace them with others of the same type
There is a serious fault; try switching off the control unit for a few seconds; if the
condition persists, it means that there is a malfunction and the electronic circuit
board has to be replaced
Control unit works correctly
This is normal when there is a change in one of the inputs: SbS, Stop, intervention
of photocells or the radio transmitter is used
All OK; when a command arrives, the control unit will restore normal operation
(after a brief delay)
An overload has been detected therefore the power to the ECSbus was switched
off. To verify, disconnect one device at a time.
To activate power to the ECSbus, simply give a command (for example, through
the transmitter)
Action
Check the devices connected to the Stop input
Stop input active
Action
SbS input not active
Normal only if the device connected to the SbS input is actually active
