10 7.7.1 Flashing Light Signalling; 10 7.7.2 Signals On The Control Unit - Nice Robus 350 Instrucciones Y Advertencias Para El Instalador

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 second's pause between flashes..

7.7.2) Signals on the control unit
On the ROBUS350 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.

Error in the internal parame-
ters of the electronic control
unit.
The maximum manoeuvre
limit/hour has been excee-
ded.
There is an error in the
internal electric circuits.

ACTION
At the starting of the manoeuvre, the devices connected to BLUEBUS do not cor-
respond to those recognized during the recognition phase. One or more devices
may be faulty; check and, if necessary, replace them; in case of modifications
repeat the recognition process (7.3.4 Recognition of Other Devices).
At the starting 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.
During the movement, the gate experienced excessive friction; identify the
cause
During the movement the STOP input was activated; identify the cause
Wait at least 30 seconds, then try giving a command. If nothing happens the-
re may be a serious fault and the electronic card will have to be replaced.
Wait for a few minutes until the manoeuvre limiting device drops to under the
maximum limit.
Disconnect all the power circuits for a few seconds and then try to give the
command again. If nothing happens there may be a serious fault and the
electronic card will have to be replaced.

ACTION
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 having the same characteristics.
There is a serious malfunction; try switching off the control unit for a few
seconds; if the condition persists it means there is a malfunction and the elec-
tronic board has to be replaced
Normal operation of control unit
This is normal when there is a change in one of the inputs: OPEN, STOP, trig-
gering of photocells or the radio transmitter is used
It corresponds to the flashing light's signal.
See Table 21
ACTION
Check the devices connected to the STOP input
STOP Input active
ACTION
STEP-BY-STEP input not active
This is normal if the device connected to the STEP-BY-STEP input is actually
active
