Advanced Functional Design
Safety loop protection
Protection switch of various safety devices compose the safety loop. When safety loop disconnects,the elevator stops immediately.
Brake detection protection
Brake arm detection switch executes real-time monitor to brake opening / closing. If the brake does not open as per the requirements,the system will not allow the elevator start.
Light curtain protection
In the process of door shut,when anybody / object that enters into / exit from the elevator car hinders light curtain,the door re-opens or keeps open.
Protection of none door opening outside door zone
Automatic door opening is forbidden under none door zone condition.
The protection functions to prevent the speed from exceeding the controlled range and causing any safety problem(s).
Prompt of overload alarm
Before the elevator shuts the door,if it detects overload signal,overload buzzer rings. It alarms and brightens overload indicating lamp. After it removes overload problem, it re-starts automatically.
Automat ic parking in trouble
When the elevator stops in none leveling zone due to any trouble,if it is not caused by safety device action,it executes self-rescue running towards the middle floor direct ion at low speed. It parks and opens the door at the nearest service floor to prevent from any trapping accident.
Emergency car lighting
When power supply disconnects,emergency lamp at the car ceiling or in the operat ion box brightens automatically.
Home landing elevator locking
When the elevator is under automatic condit ion,after it shuts home landing locking switch,the elevator will complete all the registered car command services, automatically ret urn to home landing,it enters into parking condition. As soon as locking switch opens, it immediately exits from parking condition and throws into normal running.
All selective collective running
Wait ing hall has one up and down calling button respectively. It automat ically judges the elevator running direct ion according to the car command and landing calling. It responds various car commands and landing calling signals one by one from up to down sequence.
Cancel the error-register
If the passenger presses the car command button at certa in floor and has registered it by mistake, (by then the car indicat ing lamp is bright),under the condit ion of none elevator running, you only require to press the car command button at the same floor to cancel the register. (By then the car indicating lamp dies out.)
Automatic stop of the car lighting and fan
If nobody uses the elevator within certa in period of t ime,t he car light ing and fan shut off automat ically. It re-opens at receiving any landing calling command(s).
Full-load straight travel
When the car load exceeds 80% of load rating, it does not respond any landing calling. It only responds the car command(s).
Automat ic correction of floor signal
If the floor display posit ion has error,after the system detects terminalswitch in the travel,it will automat ically correct the floor display.
Cancel reverse command(s) in the car
When the elevator travels to the farthest floor and changes the speed,it removes allthe car command register.
Self-diagnostic embedded calling button
If press calling button at certain landing for over 20 second,then it st ill does not disconnect,t he system assumes that it is embedded button. It does not register the landing calling of the same floor afterwards. Responsive lamp which corresponds to the button keeps flickering and alarming. When the button disconnects,it exits from above condition.
Automatic return to home landing
In no-operator running,if automatic return function to home landing is still effective,when no-landing calling signalt ime fulfills preset time,the elevator returns to home landing automatically.
