5.1) Description of functions

Man present Function
A movement is only made after a command is given. The Movement stops as soon as the command terminates or after a safety device triggers
("Stop", "Photo" or "Photo2") or the current sensitivity device cuts in. As soon as the movement stops, the command must be stopped before
another movement can begin.
Semiautomatic and automatic function
In the "Semiautomatic" or "Automatic" functions, following a command impulse the whole movement is performed until the required position is reached.
A second impulse on the input that began the movement will cause it to stop. If, instead of a impulse to a command input a continuous signal is main-
tained, a state of priority will be created in which the other command inputs are disabled (useful when connecting an opening timer, for example).
If the current sensitivity device or a photocell involved in the direction of movement ("Photo" when closing, "Photo2" when opening) cuts in during a
manoeuvre, the direction of movement will be inverted.
In the "Automatic" operating mode, an opening manoeuvre is followed by a pause and then a closing manoeuvre.
If "Photo" triggers during the pause, the timer will be reset with a new pause time; if, on the other hand, the Stop input triggers during the pause, the
closing function will be cancelled and the system will Stop.
Always close function
Automatically starts a closing manoeuvre, preceded by 5 s of pre-flashing, if a door is found to be open when power is resumed.
Condominium function
In the "Condominium" function, an opening manoeuvre cannot be interrupted by command impulses except for those triggering a closing manoeu-
vre. During a closing manoeuvre, a new command pulse will stop the gate and reverse the direction of movement in order to open the gate.
Pre-flashing
Following a command impulse, the flashing lamp is triggered first and then, 5 seconds later (2 seconds later in the manual mode) the manoeuvre begins.
Close again 5 s after Photo in the automatic mode or close again after Photo in the semiautomatic mode
If Photo triggers in the automatic mode during an opening or closing manoeuvre the pause time is reduced to 5 s regardless of the programmed pause time.
If Photo triggers in the semiautomatic mode during a closing manoeuvre the automatic closing manoeuvre is activated with the programmed pause time.
Photo also in the opening manoeuvre
With this function, if the "Photo" safety device triggers, movement will also be interrupted in the opening manoeuvre; if the "Semiautomatic" or
"Automatic" functions are selected, the opening movement will continue as soon as "Photo" disengages.
Activate Phototest
This function tests the photoelectric cells before each manoeuvre begins, thereby increasing system safety.
For further details, please consult paragraph 2.6 Phototest
Suction pad/electrical block
This function assigns the following functions to the Elb output (terminals 11 and 12):
• electrical block (Switch 8 Off) - the output activates during the opening manoeuvre starting from the closed door and remains active until the
door exceeds the electrical block position (programmable, see paragraph 3.5);
• suction pad (Switch 8 On) – the output activates at the end of the closing manoeuvre and remains active for the whole time the door is closed.
Traffic light in the one way mode
In this mode, the SCA output is active when the door is open and remains on during the opening manoeuvre while it switches off during the clos-
ing manoeuvre and when the door is closed. In this way, a green light can be fitted to the output that, when on, indicates the road is clear.
Traffic light in the two way mode
When switch 10 is On, regardless of the position of switch 9, the "traffic light in the two way" mode is activated; the following changes take place
in the control unit: the "Open" input becomes "Step-by-Step2", while the two "Courtesy light" (COR) and "Door open led" (SCA) outputs become
Green Light in one direction and Green Light in the other, as shown in Fig. 5. A different opening command is given for each direction of move-
ment: "Step-by-Step" (PP) for entering and "Step-by-Step2" (PP2) for exiting; two traffic lights are therefore installed with Red and Green signals
connected to the SCA and COR outputs.
The two SCA and COR outputs are normally off and, as a result, so are the traffic lights; when an open command is given with PP, the opening
manoeuvre begins while SCA activates at the same time to switch on the green entry light and the red exit light. If instead the open command is giv-
en by PP2, the COR output activates the green exit light and the red entry light. The light will remain on during the whole opening phase and the
pause phase, if any; during the closing phase, instead, the green and red lights are activated together to indicate there is no longer transit priority.
The two outputs can directly control small 24Vdc lamps for a maximum total of 10W per output. If more powerful lamps are required, it is best to
use relays piloted by the control unit outputs that in turn command the traffic lights.
