  1. Opposing closing edge
  2. Main closing edge
  3. Secondary closing edge
  4. Main closing edge (sliding door)
  5. Secondary closing edge (sliding door)

2.6 Safety equipment

dormakaba KTC 2 III Revolving Door - Safety equipment

  1. Pre-detection sensor
  2. Passive safety bumper – vertical
  3. Light barrier 1
  4. Light barrier 2
  5. Showcase door safety switch
  6. Inside emergency stop button (outside is optional)
  7. Active safety bumper
  8. Canopy sensor
  9. Safety sensor for sliding door

2.6.1 Personal protection
The optional door wing sensors detect anyone who approaches the revolving door wings.
As soon as a person enters the range of the sensors, the revolving door will slow to a lower (adjustable) speed or stop. As soon as everybody has left the range of the pre-detection sensors, the revolving door will continue with its current program settings after a restart period.
2.6.1.1 Safety bumpers
Safety bumpers are attached to the night shields and the right mullions.
If one of the passive safety bumpers (Abb. 2/2) on the night shields is touched, the revolving door will not stop. The passive safety bumper serves merely to cushion impacts. The pre-detection sensor takes over the function of the aktive bumper and stops the door. The pre-detection sensor has 2 functions (2 sensor curtains): The first sensor curtain slows down the door. The second sensor curtain stops the door. The active safety bumpers (Abb. 2/7) on the mullions are safety contact strips. The safety contact strip includes a contact that is broken when touched. If the contact is broken and the leading post of the night shield is within 700 mm of the mullion, the revolving door stops. Once contact has been restored in the safety contact strip, the revolving door will resume operation according to its current program settings after an adjustable waiting period.
2.6.1.2 Canopy sensors
These contactless sensors (Abb. 2/8) are used to detect obstacles at the main closing edges. If an obstacle has been detected at least 700 mm before the door wing has reached the post, the system immediately switches to positioning speed  or stop depending on the parameter settings. The system resumes operation when the sensors no longer detect an obstacle. The control unit tests the sensors for their function twice during each rotation. In case of a failure of the sensors, the system moves into the home position at positioning speed.
2.6.1.3 Emergency stop buttons
EMERGENCY STOP
An emergency stop button (Abb. 2/6) is located on the inside of the building on the leading mullion and optionally also on the outside of the building, depending on the options selected for the order. When the emergency stop button is pushed, the revolving door stops immediately and the drive unit is disengaged. Then it is possible to rotate the door wings manually. Depending on the model, the emergency stop can be reset by pulling or turning the emergency stop button, and the revolving door will resume operation according to its current program settings.
2.6.1.4 Light barriers
The contactless sensors (Abb. 2/3 and Abb. 2/4) are mounted in the foot area horizontally between door wing and strut. During rotation, as soon as persons are detected, the system stops immediately. After leaving the safety zone, the system will restart. The light barrier 1 slows down the door. The light barrier 2 stops the door.
2.6.1.5 Showcase door safety switch
The switches (Abb. 2/5) are located on the showcase doors.
The system stops immediately if one of the showcase door leaves is opened during the rotation. In order to restart the system, the door leaves must be closed.
2.6.1.6 Speed monitoring
The speed of KTC-type revolving doors may not exceed 750 mm/seconds, therefore the KTC 2 cannot be set to a faster speed. When setting the speed, the types of users have to be considered (e.g. also persons with restricted mobility or elderly persons). Danger to persons has to be prevented. This may require reducing the speed of 600 mm/seconds set at the factory.
2.6.1.7 Sliding door locking contact
In case the sliding door is opened during the rotation of the revolving door, the system moves into the home position at positioning speed. To restart the system, the sliding door must be closed.
2.6.1.8 Control unit
The control unit of the system is located in the ceiling. The control unit is a self-monitoring system, which immediately identifies defects or malfunctions of the system, then responds and displays them.
2.7 Personnel qualification
WARNING
Risk of injury due to insufficiently qualified personnel!
Insufficiently qualified personnel cannot assess the risks associated with handling the revolving door, thus putting themselves or others at risk of serious or life threatening injury. If unqualified personnel work on the unit or stay in the unit’s danger zone, this results in dangers that could cause serious injury and considerable property damages.
