【 Weak current College 】 elevator door systems often produce various fault

Equipped with automatic doors for lifts, door systems often produce various fault affecting the normal operation of the elevator. Now the current large-scale use of XPM elevator, for example.

1. the lift cannot be closed, and you cannot open the door.

Maintenance and troubleshooting of: ① control circuit breaker 1RD, 2RD or door circuit breaker or fuse 11RD too loose, tighten or replacement; ② door drive belt skidding, tensioning belts or replacement; ③ crane motor DM damage, multimeter M3, M4 110V DC voltage between, and the door will not turn on the electric motor is damaged, be repaired or replaced; ④ door resistance RMD broken wires, replace the resistance of door circuit RMD; ⑤ individual connection endpoint (M1 or M2 or M3 or M4) loose, tighten the line open; ⑥ in base station with the key cannot be opened, closed, 22, 24 point shorted, elevator door open or 22, 32, shorted, elevator door open, outside key lock switch DYK contact bad or broken. If bad, use alcohol to clean, and adjust the contact spring; if contact broken, replace the DYK.

2. the station after leveling, elevator door open.

Maintenance and troubleshooting of: ① secondary door limit switch 2KM damage, so that the open relay JKM cannot have electricity, the elevator was unable to open the door. Shorted point 38, 01 check to determine that the damage to the door, replace 2KM 2KM; ② relay JKM damage, replace the JKM; ③ door electrical circuit failure, such as running relay JYT normally closed contact is blocked, to exclude; ④ open regional permanent relay (commonly known as Reed pipe) is damaged, the door control relay JMQ cannot suck, it normally open contact is still broken, unable to have electric relay JKM, not open the door, replace the open regional permanent relay.

3. press the close button, the door is not closed.

Maintenance and troubleshooting of: ① close button AGM contact bad or corrupted, shorted point 23, 24, determination, and then checkthe repair or replacement; ② 3 closed limit switch 3GM damage, make closed relay JGM cannot have electricity, Elevator could not close the door, shorted 28, 01-point check determination, to close the door, damage, replace the description 3GM 3GM; ③ closed relay JGM damaged, replace JGM; ④ start open relay 1JQ for damage, it normally open contact 1JQ still broken, JGM cannot have power to shut the door, replace relays 1JQ.

4. elevator has accepted the selected layer signal that the door is closed, but you cannot start.

Maintenance and troubleshooting of: ① car door closed in place, but the car door interlock switch is connected, KMJ door lock relays JMS cannot have electricity, and therefore cannot start, adjust or replace switch KMJ; ② Hall door is not closed, the hall door interlock switch of the KMT not connected, door lock relays JMS cannot have electricity, and therefore cannot start, reset switch, as does not work, you should adjust door speed or door lock switch KMT; ③ doors in place, but the KMT lock switch fails, the removal or replacement of the lock; ④ run relay JYT fails, repair or replace JYT.
5. the door is not closed, the lift will start the selected layer.

Maintenance and troubleshooting of: ① door lock relays JMS have card blockage often sucks, exclusion and replace relays JMS; ② door lock switch KMT contact adhesive (micro switch locks) to eliminate or replace a door lock.

6. lift in traffic stop suddenly.

Maintenance and troubleshooting of: Mun knife gate wheel, so that collisions lock arms disengage, door lock switch lock relays KMT disconnect, JMS, outage, adjust immediately to stop the elevator door wheel and door blade position.

7. door speed transmission.

Maintenance and troubleshooting of: ① door level limit switch 1KM damage, replace the switch 1KM; ② door shunt resistor RKM broken wires, replacement resistor RKM.

8. closing speed transmission.

Maintenance and troubleshootingof: ① door a, second level limit switch 1GM, 2GM damage, replace the 1GM, 2GM; ② door shunt resistor RGM broken wire, replace the resistance of the RGM.

9. switch on the door slowly

Maintenance and troubleshooting of: door machine belt skidding, tensioning belts.

10. switch door door leaf vibration.

Maintenance and troubleshooting of: ① door pulley, replace the door wearing a pulley; ② door Rails deformation or deflection correction loose, adjust, door Rails, fastening rails; ③ ground Ridge in the chute dust or dirt to prevent door slide, you should clean up the chute; ④ two wheel lock and door knife is not close, gap, adjust the lock.
