Safebox S1

The magnetic tape holds the unique position information as a magnetic code. It is mounted free-hanging in the shaft using a mounting kit and guided by means of a plastic guide on the sensor. The measurement is thereby always performed contact-free. The guide serves only to keep the tape within a defined distance to the sensor.

The position sensor is designed for the FST controller and, together with the Safebox S1 analysis unit, forms a complete system that satisfies the safety functions in the lift in accordance with EN 81-20/50 and EN 81-21.

• SHAFT POSITIONING SYSTEM
  The S1 shaft positioning system
  replaces the conventional absolute positioning system.
• SPEED MONITORING AND TRIGGERING
  The absolute position control of the S1 speed monitoring
  enables permanent monitoring in both
  directions of travel.
• SHAFT DOOR MONITORING (EMERGENCY RELEASE)
  The emergency release is monitored by the S1.
• PROTECTED SPACE MONITORING
  The protected space alternative measures are monitored by the
  S1. The protective measures are not necessary if a
  “pre-triggered stopping system” is used (option).
• INSPECTION END SWITCHES
  The need for the classic inspection end switches is
  eliminated through the absolute, reliable position control.
• EMERGENCY END SWITCH
  The need for the classic emergency end switch is
  eliminated through the absolute position control.
• DOOR BYPASS
  The car and blocking-agent contacts are bypassed
  for “approach and re-levelling with open door” by the S1.
  The magnet switches and magnets do not need to be installed.
• LOCKING OF THE INSPECTION DRIVE EQUIPMENT IN ACCORDANCE WITH EN 81-20
  Per the requirements of EN81-20, the locking of the
  inspection drive equipment of car and pit as well as
  priorities for auxiliary mode control and bypass is performed by the S1.
• UCM-A3 DETECTION AND TRIGGERING
  No additional UCMA3 sensors
  and analysis units need to be mounted; these functions are performed by the S1.
