Elevator Control

This type of programmable function is used to lock and unlock selected floors for a specific elevator group based on the state of an output. It is also used to implement the fire drop (emergency egress) state on floors.

The Elevator Function Mode activates or deactivates the Elevator Control Mode based on the state of the Output to Check. The elevator control mode then determines what action the floors will take.

You can configure either continuous control (the function always checks the floor state and maintains its status) or pulse control (the function only controls the floor status when the output changes state).

  • Continuous modes check the floor state every 30 seconds. If the state is not correct the function reasserts control and updates the floor state.
  • Pulsed or edge triggered modes only change the floor state at the time when the control mode changes state, and do not check or control it at other times.

Configuration

  • Elevator Function Mode: This field determines the control response to the output status, i.e. whether the output turns the chosen Elevator Control Mode on or off.

    The options are:

    • Follow and Test: The elevator control mode continuously follows the state of the output.

      When the output is ON, the elevator control mode is ON. When the output is OFF, the elevator control mode is OFF.

    • Invert Follow and Test: The elevator control mode continuously follows the state of the output in an inverted manner.

      When the output is ON, the elevator control mode is OFF. When the output is OFF, the elevator control mode is ON.

    • Pulse On: The elevator control mode is activated on the rising edge of the output.

      When the output turns ON, the elevator control mode turns ON.

    • Invert Pulse On: The elevator control mode is deactivated on the rising edge of the output.

      When the output turns ON, the elevator control mode turns OFF.

    • Pulse Off: The elevator control mode is activated on the falling edge of the output.

      When the output turns OFF, the elevator control mode turns ON.

    • Invert Pulse Off: The elevator control mode is deactivated on the falling edge of the output.

      When the output turns OFF, the elevator control mode turns OFF.

  • Elevator Control Mode: This field defines what action the floor group takes when the elevator control mode is activated or deactivated.

    • Emulate Unlock Menu: When the elevator control mode is activated the floor group will be unlocked for the duration of the Token Time (below). When the elevator control mode is deactivated the floor group is locked.

      This setting is not compatible with continuous elevator function modes.

    • Latch Elevator Unlock: When the elevator control mode is activated the floor group will be latch unlocked. When the elevator control mode is deactivated the floor group will be locked.
    • Fire Control Elevator Unlock: When the elevator control mode is activated the floor group will be latch unlocked indefinitely. This command overrides other features that might be holding the floors locked, such as area status. When the elevator control mode is deactivated the floor group will return to its previous state.

  • Output To Check: The output used to control the floor group. The relationship between the output and the elevator control mode is determined by the Elevator Function Mode above.

  • Elevator Group: The floors controlled by this function will be locked/unlocked for the elevator cars in this elevator group only.

    For example, a programmable function might be used to latch unlock the floors in the public elevators but not the maintenance elevators.

  • Floor Group: The floors in this group are controlled by the programmable function. Floor behavior is determined by the Elevator Control Mode above.

  • Token Time: If the Elevator Control Mode is set to Emulate Unlock Menu the floors will be unlocked for this length of time when the elevator control mode is activated.
