The block is intended to be used as a component parts of controlling systems for passenger, hospital and cargo elevators with variable and non-variable drives of elevator car traveling speed 0.63 m/sec, 1.0 m/sec, 2.0 m/sec.

The block enables elevator traveling speed control and elevator safety circuit opening in case of:

  • elevator car traveling speed exceeds the allowed value;
  • elevator car moves upwards when the speed limiting block signals it to move downwards;
  • elevator car moves downwards when the speed limiting block signal prescribes it to move upwards;
  • there is no control signal of elevator car travel direction while the car is moving;
  • there is no any out of two pulse chains of encoder with the signal of elevator car travel direction set to the speed limiting block
