    The NO contacts of the internal relays are connected in series so that the current paths are not closed before both relays have switched� Block diagram The target value is set via 3 switches on the front of the device� The value can be set in "rpm"/"Hz" (DD110S) or "Hz" (DD111S)�...
  • Page 8: 3�2 Safe State Of The Output Relays

    3.2 Safe state of the output relays Output relays are de-energised� Current paths are open� 3.3 Switching function "Overspeed" The output relays de-energise when the event occurs (selected frequency Fo reached)� The relays switch on again when the value falls below the preset value reduced by hysteresis (Foh)�...

  • Page 13: 5�2 Automatic/Manual Mode Selection

    5.2 Automatic/manual mode selection If overspeed is detected, the current paths open and the drive is switched off� As a result the input frequency falls below the switch point and the current paths close (below Foh)� By means of the automatic/manual function it can be prevented that the current paths close automatically when the input frequency drops below the Foh value�...
  • Page 14: 5�2�2 Manual Mode

    5.2.2 Manual mode Manual mode In this operating mode, the outputs of the device are only activated if the input frequency is below the target value and after the restart signal has been sent to the device via an external restart command (terminal Y5)� Once the overspeed has been detected, the relay outputs are not switched�...
  • Page 15 The restart signal must be applied for 0�3���5 s� Otherwise the command is rejected� If the restart command is activated (rising edge or falling edge or both) when the frequency is between Fo and Foh, the command is also rejected� When the device is waiting for the restart command, the yellow LED [ENA] flashes�...
  • Page 16: 5�3 Enable Input

    5.3 Enable input If several devices with different switch points are used for overspeed monitoring of a drive, the devices whose switch point value is not relevant can be "switched off" by means of the two enable inputs� The current paths are then closed� In this way the relay status can be controlled via the enable input after power-on of the device�...
