ESCALATOR

No.	Safety function	Explain
01	Electro-static brush	Remove running step (tread)electro-statics.
02	Emergency stop press-button	When it needs emergency stop, press “emergency stop switch” for protection.
03	Skirting protection	Protection functions if foreign matter is clamped between step and skirting.
04	Handrail entry protection	Protection functions if any foreign matter is clamped in handrail entry.
05	Drive-chain broken protection	Protection functions if drive chain is broken or overlong.
06	Over-speed, under-speed protection	Protection functions when speed exceeds or is lower than the rated speed.
07	Non-operation reversal protection	Protection functions if running direction of escalator or handrail is reversal to designated direction.
08	Open-phase, error-phase protection	Protection functions for motive power open-phase or error-phase.
09	Electrical loop protection	Protection functions for short-circuit of power loop.
10	Motor over-load.over-heat protection	If motor current exceeds 120% of rated current, escalator stops automatically.
11	Step (tread)sunken protection	Protection functions for sunken/damaged step (tread).
12	Step (chain) broken protection	Protection functions for broken or overlong step chain (tread chain).
13	Comb-teeth safety protection	Protection functions if foreign matter is clamped in comb-teeth.
14	Step gap lighting	Top and bottom of lighting escalator.
15	Trouble self-diagnosis	It can automatically diagnose any error, Memory function is convenient for repair. It enhances the action efficiency.
16	Automatic lubrication	It can precisely, promptly, quantitatively provide escalator/moving walk with oiling/ lubrication.
17	Alarm-bell starting device	During escalator start, after it prompts passengers for 3 second, it begins upward running.
18	Handrail anti-electrostatic device	Remove running handrail electro-statics.
19	Handrail speed-detection function	Protection functions if handrail running speed is lower than rated speed.
20	Step loss function	If upper escalator and lower step are lost, escalator stops immediately.
21	Anti-climbing device	It prevents from passengers’ climbing danger.
22	Functional safety protection device	Related programmable electronic safety system (PESSRAE) It ensures safe escalator/moving walk running.

No.	Safety function	xplain
23	Skirting brush	It prevents passengers’ shoes, trousers etc. from touching the skirting It thus enhances the passengers’ safety. Meanwhile it protects normal operation of step and overall escalator.
24	Machine room guard-pane	It prevents from touching the step in maintenance. It thus enhances security of repair & maintenance staff.
25	Trouble display	It shows trouble code in display. It is convenient for repair staff.
26	*Microwave/photo-electricity/tread self-start	It saves energy through step or slow running.
27	*Comb-teeth heating function	It avoilds freezing in low temperature.
28	*Truss heating function	It avoids step breezing in low temperature.
29	BMS long-distance control system	It executes long-distance monitor to single elevator and centralized monitor to multiple elevators.
30	*Oil/water separator	If escalator is installed outdoors, it separates from lubricating oil. it thus avoids enyironmental pollution.
31	*Comb-teeth lighting	It enhances brightness when step enters into comb-teeth. It is more secure.
32	*Step up-skip function	If step skips upward, switch actions and escalator stops.
33	*Additional brake	When drive chain is broken or running speed is over-speed, escalator stops automatically.
34	*Mechanical anti-reversal function	Protection functions when escalator running direction is reversal to designated speed.
