Blinker
The electronic card supplies an on/off control (flashing light) to the lamp. The logic of the blinking allows displaying the gate's operating.
Quick flashing light : it signals the opening phase
Slow flashing light : it signals the closing phase
The blinker is off when the gate is blocked in pause before the closure phase.
The device supplies an on/off control (fixed light) to the lamp for approx. 1,5 sec. before the motors start (pre-alarm).
Work time
The motors' work time is controlled by two independent digital timers. For the automation system to work properly the operating time value to be set
must be slightly (min. 2 sec.) above the gate's actual work time. If any command interrupts the wing's travel before its end, the Timer stops and the
elapsed time is stored in memory. Therefore the unit can determine, with a fair approximation, the partial working time necessary to the wing to end its
travel. Thanks to this feature it is possible to avoid that the motor works for a long time after the end of the wing's travel, thus reducing overheating to
the minimum.
Warning : In case of absence of power supply the stored position will be lost.
Kickback
This procedure can be enabled or excluded. It is usually employed to help the electric lock release during bad weather conditions (wind, ice, etc.). The
"kickback" procedure consists of a logic sequence operating the electric lock for approx. 1 sec. after a short closure phase (approx 1 sec.) with the
gate closed. The electric lock is released only after the wing has started its opening motion.
M1 delay at opening
The unit causes a fixed delay of approx. 2 seconds between the first wing's (M2) and the second wing's (M1) start during the gate's opening phase.
This delay is imposed irrespective of the position from which the gate starts to open. This delay may be cancelled by setting the M2 delay trimmer to
its minimum value.
Warning: In case of single-wing gate it is necessary to set the M2 delay trimmer to its minimum value.
