"Automatic" mode
After the power is supplied to the electronic card the first start command determines an opening cycle. During the slow-down phase, at the end of the
two work times or after the Limit switches have operated for both motors, the gate stops. The pause period starts (blinker off). At the end of the pause
period the gate closes automatically. The operating cycle is complete only when the closing motion has ended. If a start command is supplied before
the end of travel is reached the gate stops. A new start command will cause the gate to reverse its motion. If a start command is supplied during the
pause period the operating cycle is interrupted and the gate does not close automatically. A further start command will determine a closing cycle.
"Condominium" mode
After the power is supplied to the electronic card the first start command determines an opening cycle. During the slow-down phase, at the end of the
two work times or after the Limit switches have operated for both motors, the gate stops. The pause period starts (blinker off). At the end of the pause
period the gate closes automatically. The operating cycle is complete only when the closing motion has ended. If a start command is supplied while
the gate opens, the command will have no effect. If a start command is supplied while the gate closes, the gate will stop and reverse its motion after
approx. 1.5 sec. If a start command is supplied during the pause period, the period will be reset and the automatic closure will start later.
Important : If the gate opening is controlled by a clock the "condominium" mode must be enabled.
"Single wing" mode
This mode is employed with single-wing gates. When enabled, it drives the motor M2 only. The operating modes described above remain unchanged.
When the "single-wing" mode is selected the dip switch 3=ON must be set.
Note : At the beginning of each opening cycle, with the gate closed, the electric lock can operate in 2 modes :
1) If dip switch 4=OFF the electric lock operates a split of second (0,8 sec) before the first wing (M2) starts , and stops operating 2 Sec. after the
wing's start.
2) if dip switch 4=ON the electric lock operates for a short time (approx. 1 sec.) during the wings' closure, and stops operating 2 Sec. after that
the M2 wing starts the opening. The "kickback" procedure is usually employed to help the electric lock's release during bad weather.
In any operation mode, the safety devices causes the following effects :
Stop : If the stop command is enabled no cycles can start and the start command will have no effect. If a stop command is supplied during motion,
the gate will immediately stop e interrupt its operating cycle. This condition will continue until the stop command is on. A start command
following a stop command always determines an opening cycle. A stop command supplied during the pause period interrupts the operating
cycle. A start command subsequently supplied will start a closure cycle.
Photo-cell : This device has effect only during the closure phase or in the pause period. If an obstacle covers the photo-cell during the closure phase ,
the gate stops and reverses its motion after approx. 1,5 sec. If an obstacle covers the photo-cell during the pause period this last one is
reset and the automatic closure is therefore delayed.
Photostop : If an obstacle covers the photo-cell during the gate's motion (opening or closure), or during the period
preceding the operating cycle's start, then the gate is temporarily stopped, until the obstacle is not removed. The blinker will light with a
fixed light to signal the irregular condition. When the obstacle is removed and the photocell is freed, an opening cycle will start. This does
not apply when a start command determines the closing phase in step-by-step mode at the end of an opening cycle. If an obstacle
covers the photostop during the pause period this last one is reset and the automatic closure is therefore delayed.
