Signals On The Control Unit - Nice WIDE S Instructions And Warnings For Installation And Use

8.2 SIGNALS ON THE CONTROL UNIT

The LEDs near the control unit's terminals issue special signals to
indicate both normal operation and any anomalies.
The following table describes the causes and solutions for each
type of signal.

Possible solution
Check for the presence of power; check that the fuses are not
blown; if necessary, identify the cause of the fault, then replace the
fuses with other fuses having the same specifications.
There is a serious anomaly; try switching off the control unit for a
few seconds; if the condition persists, it means that there is a fault
and the electronic circuit board must be replaced.
Normal control unit operation.
At the start of the manoeuvre, one or more photocells are blocking
the movement; check whether there are any obstacles. During the
manoeuvre, this is normal if an obstacle is present.
During the gate's movement, the motors encountered more
resistance. Verify the cause and increase the motor force if
necessary.
At the start of the manoeuvre or during the movement itself, the
ALT (STOP) input intervened. Identify the cause.
Wait at least 30 seconds then try giving a command and
disconnect the power supply if necessary. If the condition persists,
there may be a serious malfunction and the electronic board
needs to be replaced.
Wait for a few minutes until the temperature drops under the
maximum limit.
Check the devices connected to the STOP input.
Stop input active.
Check the devices connected to the PHOTO input.
Photo input active.
Check the devices connected to the PHOTO2 input.
Photo2 input active.
Step-by-Step input inactive.
It is normal if one of the devices connected to the Step-by-Step
input is active.
