check whether or not the encoder LED is flashing during movement of the motor. The flashing frequency
may be higher or lower in relation to the speed of movement. With the motor at a standstill the LED may be
On or Off, depending on the exact angular position at which the motor shaft has stopped.

must be adopted in the event of a power failure or in the case of system faults. The manual
manoeuvre will allow free movement of the bar only if installed correctly and with genuine original accessories.
1.
Lift the lock cover disk. Insert the key and turn it clockwise
2.
Turn the release handle counter-clockwise. Move the bar manually
To lock the bar: return the release handle to its original position, turn the key and extract it.

Maintenance operations must be performed in strict compliance with the safety directions provided in this
manual and in accordance with applicable legislation and standards. Although Signo does not require any
special maintenance operations, regular inspections carried out at programmed intervals will ensure longer life
of the system and reliable operation of the safety devices. For this purpose all the tests and checks specified in
heading 4.1 "Testing" should be performed.
If other devices are installed, adhere strictly to the directions given in the relative maintenance plan.

To assist planning of maintenance interventions for the entire system the control unit is equipped with a cycles
counter that increases its value at each opening manoeuvre. The increase is signalled by a flash of the
maintenance LED (MAN). The cycles counter value is constantly compared to an alarm threshold value
(programmable by the system fitter) and checked against a warning threshold (set automatically at
approximately 6 % below the alarm threshold). When the number of cycles executed exceeds the warning
threshold the maintenance LED flashes only during manoeuvres of the barrier, while if the alarm threshold is
exceeded this LED flashes constantly (when the motor is stopped and during movements) thereby signalling the
urgent need for maintenance.
The alarm threshold can be programmed from a minimum value of 1000 to a maximum of 255000 cycles in
multiples of 1000.
