Traffic Lights In Both Directions; Description Of Functioning Modes - Nice WIL Manual De Instrucciones

English
4.3) TRAFFIC LIGHT IN BOTH DIRECTIONS:
The function of the traffic light in both directions is mainly to control the flow of traffic in both directions as they go across the
controlled road barrier.
A different command is placed for opening in both directions: P.P. for entering and P.P.2 (Open) for leaving; two traffic lights are
installed with the indications Red and Green, connected to the Bar Open Indicator and Courtesy Light outputs.
Fig. 4
The two outputs are usually off and so are the two traffic lights; when a command is given with P.P. to enter, movement is started
and the Bar Open Indicator output is activated: this means there will be a green light to enter and a red light to leave.
But should the command be given with the P.P.2, the Courtesy Light output will be activated and there will be a green light to
leave and a red light to enter.
The light will stay on for the entire opening manoeuvre and for the subsequent pause time; during the closing manoeuvre both
the green and red lights will be activated (the result being yellow) to indicate there is no longer any transit priority (see table).
The two Bar Open Indicator and Courtesy Light outputs can directly control small 24 V d.c. lamps for a total of 10 W. If stronger
lamps have to be used, use the relays piloted by the unit outputs that control, in turn, the traffic lights.
Only now, when all the adjustments have been made and with the electricity off, do we advise you to connect the radio receiver.
5.1) DESCRIPTION OF THE FUNCTIONING MODES:
In the manual functioning mode the OPEN input allows movement up to the opening point; the CLOSE input allows movement up
to the closing point; STEP-BY-STEP allows alternative opening and closing manoeuvres; as soon as the command in input stops,
movement stops. In the opening phase movement stops when the maximum opening point is reached or if there is no consent
from PHOTOCELL 2; to the contrary, in the closing phase movement will stop at the maximum closed point or if there is no consent
from the PHOTOCELL. If STOP is triggered it will cause movement to stop immediately both in the opening and closing
manoeuvres. Once movement has stopped the command in input has to be stopped before any new movements can be rective)
In either of the automatic functioning modes (semiautomatic-automatic and closes always) a command on the OPEN input will
cause an opening manoeuvre; if the command remains (TIMER) once the bar is open, the bar remains "frozen" in an infinite
pause; only when the command stops will the bar be able to close. Command pulses on the CLOSE input will cause a closing
manoeuvre; if the command remains the bar will stay locked in the closed position until the command ceases and only then can
it be reopened. A pulse on STEP-BY-STEP causes alternative opening and closing.
A second pulse on the STEP-BY-STEP or on the same input that started the movement, will cause a Stop.
Whether in the opening or closing phase, if STOP triggers it will cause movement to stop immediately.
In an opening manoeuvre, triggering of the PHOTOCELL has no effect while PHOTOCELL 2 will cause reversal of movement; in
a closing manoeuvre, triggering of the PHOTOCELL causes movement to reverse followed by a new pause and lastly reclosing.
If at the beginning of an opening movement, the PHOTOCELL input does not give consent, the request to open is cancelled.
If the automatic functioning mode is being used, there will be a pause time subsequent to an opening manoeuvre and followed
by a closing manoeuvre. If, during the pause the PHOTOCELL triggers, the timer will be reset with a new time; if, on the other
hand, a STOP comes into play during the pause, the reclosing function will be cancelled and there will be a STOP condition.
