TIME OPERATING LOGIC
To set the time operating logic,
Dip 1 must be OFF.
Dip 2 = OFF.
Trimmer T1 is adjusted to set the time in which you want the two traffic lights to both be red (from 5 to 120 seconds).
Trimmer T2 is adjusted to set the time in which one of the two traffic lights stays green (from 5 to 120 seconds).
Trimmer T3 is indifferent. The time operating cycle has the following steps:
1. At the time of switching on the electronic control unit, both traffic lights are red for the time set by the trimmer T1(time T1).
2. After the time T1, the traffic light connected to the terminals "1" turns green while the one connected to the terminals "2" stays red.
3. The traffic lights stay in this state for the time set by trimmer T2 (time T2).
4. After the time T2, both traffic lights turn red for a time T1 to let the last ones in clear the passage.
5. After the time T1, the traffic light connected to the terminals "1" stays red, while the one connected to the terminals "2" turns green.
6. After the time T2, both traffic lights turn red for the time T1 to let the last ones in clear the passage.
7. The cycle restarts from point 2 and is repeated endlessly.
OPERATING LOGIC WITH SENSOR DEVICES
To set the operating logic with sensor devices,
Dip 1 must be ON.
Dip 2 must be OFF, for N.O. contacts.
Dip 2 must be ON , for N.C. contacts.
The trimmer T1 is adjusted to set the time in which you want both traffic lights to be red (from 5 to 120 seconds).
Trimmer T2 is adjusted to set the time in which one of the two traffic lights stays green (from 5 to 120 seconds).
Trimmer T3 is adjusted to set the time needed to block a continuous reset of the time T2, due to one of the two traffic lights repeatedly
passing, and thereby also satisfy requests for access from the opposite side (from 5 to 120 seconds).
The time operating cycle has the following steps:
1. At the time of switching on the electronic control unit, both traffic lights are red for the time set by the trimmer T1 (time T1).
2. After the time T1, the first sensor to be energized (for example a photocell) calls green for the traffic light associated with it for a time set
by the trimmer T2 (time T2), while the other traffic light stays red.
3. The green time T2 is reset each time the sensor is energized, until the opposite sensor is free; otherwise, the cycle passes onto point 7.
4. If the sensor is no longer energized at the end of the time T2, both traffic lights turn red.
5. The traffic lights stay on red for the time T1. If in this phase an activation command reaches the inputs, this is saved and taken into
account at the end of the time T1.
6. After the time T1 the cycle restarts from point 2.
7. If the opposite sensor is also energized, the count starts for the time set by the timer T3 (time T3).
8. At the end of the time T3 the continuous reset of the time T2 is blocked (due to repeated passing from one of the two parts).
9. At the end of the time T2 both traffic lights are on red for the time T1.
10. At the end of the time T1 the call for green made by the other traffic light is satisfied and the cycle restarts from point 3.
NOTE
a) The power supply of the clean contacts controlled by the relays depends on the type of traffic light used: for traffic lights with light bulbs it
will be necessary to have an electric panel that supplies a voltage of 230V ac, whereas ones with LEDs will need a voltage of 24V ac-dc.
b) The outputs of the electronic control unit for red are connected on the N.C. contact of the relay, then, if the card breaks down, the traffic
lights will always be on red.
c) The inputs of the sensor devices only see the changes in status of the sensor, so if this breaks down always giving the busy status (for
example a photocell blinded by sunlight) the input is ignored always giving the red status on the output associated with it.
d) The electronic card needs no particular maintenance. In any case, periodically, at least twice a year, check the traffic lights work properly
as set on the card.
e) The dipswitches must be set when the card is not powered.
f) In order to protect the relays from short-circuiting, use fast-acting fuses (F1 and F2) of adequate capacity (max 2A) on the common
terminals of both traffic lights.
g) It is recommended to insert a miniature circuit breaker before connecting the power supply to the control unit.
