Step 4, controller 22 control the electrification of 21 coil windings of relay, normally-closed contact after the electrification of 21 coil windings of relay
It disconnects, room lighting circuit has a power failure, socket, air conditioner loop normal power supply.
Step 5, early warning switch 20 controller 22 detect whether to press reset button 28,
Step 5 is repeated if not pressing reset button 28,
If pressing reset button 28, controller 22 closes 21 coil windings power supply of relay, and lighting loop restores electricity
And execute step 6.
The starting power failure timer of controller 22 of step 6, early warning switch 20, sets aside some time to electricity payment again,
After power failure timer setting time, controller 22 detects whether electric power dispatching system is also sending the alarm that Sorry, your ticket has not enough value,
If not sending and thening follow the steps 1, if also thening follow the steps 7 in the transmission warning message that Sorry, your ticket has not enough value.
Step 7, early warning switch 20 controller 22 control 21 coil windings of relay electrification, relay 21 it is normally closed
Contact disconnects, lighting loop power loss, while 22 blocked reset button 28 of controller, can not restore to supply after pressing reset button 28
Electricity prompts user must electricity payment.
Step 8, controller 22 detect whether electric power dispatching system is also sending the alarm that Sorry, your ticket has not enough value,
If there is alarm signal then illustrates no electricity payment and repeats step 8,
Illustrate electricity payment if without alarm signal, controller 22 of early warning switch 20 ifs controls relay
The power-off of 21 coil windings of device restores lighting loop power supply, and executes step 1.
