Advanced Functional Design
Driver running
Arrival automatic door-open, manual door-shut, internally selective automatic register (anti- nuisance, accidental operation removal), outer calling automatic clockwise stop.
Optical curtain protection to the safety edge
If the safety edge or optical curtain has been warded off, it will immediately stop the door-shut actuation and automatically opens the door.
None door-shut in over load
When it is over load,the door does not shut,overload light is bright,it rings the buzzer and the lift does not start.
Accidental operation removal
If repeatedly press inner-selection button,it can cancel the error register. (It dies out the inner selection lamp.)
Fire-fighting return
After the fire-fighting switch closes, the system enters into fire-fighting running.
The system will remove all the landing calling and car command signals, and it automatically return to fire-fighting home landing,and the door keeps open.
If the elevator is traveling reversely, it parks at nearby floor, and returns to fire-fighting home landing with the door keeping closed,after that it keeps the door open.
Inlaid self-diagnosis of the outer calling button
If certain outer calling button has been continuously pressed for more than 20 seconds, the system takes it as an inlaid button (can not be reset), it will then not register the outer calling of this floor and keep flickering & alarming to the corresponding outer calling of this button.
Parking control
When it actuates the key switch in the designated floor, the lift will return to the designated floor after responding to all the commands, meanwhile it will start the energy-saving mode,cut off the illumination in the car and lighten the outer switch indicating lamp.
Interference assessment
It makes the corresponding assessment to the site control cabinet grounding (restricting the interference source), well wire earthing (the reliable shield) conditions.
It directs the adjustors to remove the hidden danger and provides the micro-computer control system with the more secure and reliable work environments.
Emergency electric start
Emergency electric start is an emergency measure that can be adopted under the condition that it has the normal power supply when there is something wrong with the safety loop (the safety loop in jump out part) so that it can release the passengers who are stranded in the car within the shortest time possible and restore the normal use of the elevator.
Braking detection protection
It implements a real-time monitor to the brake open I shut through the braking arm detection switch. If the brake does not open upon the request, the system will prohibit the lift start.
Terminal speed change and floor number correction
When the system detects the terminal switch in running,the lift will be forced to change the speed and automatically correct the floor display.
Safety loop protection
When it disconnects the safety loop,the lift will immediately stop the operation.
