Traffic Light Control Unit Manual

Ⅰ.System Principle

This system is composed of two control units and one handheld transceiver.

Where control units named as 1＃ and 2＃ receive the signal and control the

external device. 1＃ control unit and 2＃ control unit can work alone in single

mode, They can also work exclusively in dual mode. The handheld transceiver can

control the control units via wireless radio and display the work status of the

control units. The sketch map is shown below:

Ⅱ.Function description：

1. Power-on/Reset status: While the power switch turns to ‘ON’, the

following actions will be executed.

a) When Pin 2 of ‘GATE SENSOR’ socket keeps in low level, the inside

relays will control pin 1 of ‘MOTOR’ socket to export voltage 13.8v

and pin 4 to connect to grounding. When Pin 2 of ‘GATE SENSOR’

socket inputs a high level (>5V), the pin 1 of ‘MOTOR’ socket is hung.

b) Pin 1 of ‘SIGNAL’ socket exports 13.8V voltage, Pin 2 connects to

grounding.

c) The four LEDs of ‘LOW FULL’ indicates the voltage status.

2. Working in Single mode (‘MODE’ Switch of Control unit 1＃ and 2＃

both turns to ‘SINGLE’ position.)

a) The indicator Led of Single Mode will turn on, and at the same time

‘FLAG1’ indicator Led of Control Unit 1# and ‘FLAG2’ indicator Led

of Control Unit 2＃ will turn on.

Pin 3 to grounding alternately. At the same time, Pin 4 of MOTOR socket will export 13.8V voltage and pin 1 will connect to grounding. When pin 5 of ‘GATE SENSOR’ socket inputs high level(>5V), Pin 4 of ‘MOTOR’ socket will disconnect with interior voltage. Otherwise when control unit 1# keeps in open status(i.e. control unit 1# of pin 2 of GATE SENSOR socket keeps in low level), it will be closed first and then execute the above actions. e).
