    The module is manufactured in 2 different enclosure versions: B-Option MCB140 design PCB for direct mounting inside the enclosure of the frequency converter to be monitored (all Danfoss frequency converters with B-Option slot, with the exception of FCD302). The safety outputs are connected to their corresponding control inputs.

    Input SS1 STOP/EMERGENCY stop Pressing the Emergency Stop switch trips the defined slowdown of the drive to be monitored by the Ramp output. If the drive does not come to a standstill within a specified time frame (Parameter P301), then the instantaneous STO is tripped by the STO_O and ExC outputs.

  • Page 11: Safety Outputs

    Each time the STO_O output is destaged, this trips STO on the frequency converter (this signal must always be connected to terminal 37 for Danfoss VLT frequency converters). Once SS1 is enabled, such destaging always occurs if either the monitoring time has elapsed or the drive was detected by the sensors as being at a standstill.

  • Page 12: Special Aspects Of Single Channel Use

    This section explains the logical functionality and priorities of the MCB14x safety operations. SS1 always has the highest priority. (terminals 8/9 on MCB140, terminals 11/16 on MCB141) If a safe stop 1 is enabled (input signal high -> low), then a braking ramp is tripped on the frequency converter (output signal high ->...
  • Page 13 If the Door inputs (terminals 12/13 on MCB140, terminals 13/18 on MCB141) are low (i.e. in the event of an open separating protective device, for example), then STO is enabled. This behaviour changes if SLS is also enabled.

  • Page 14: Example Application

    6.1. Example application A FC302 with MCB140 and a self-closing door with two safety outputs for position monitoring and an input for magnet control are used. During SLS operation, jogging is possible in the event of an open separating protective device.

    6.5. Fault management Any faults detected by the system are divided into 3 categories based on their significance and impact: Fault category 0 Following debugging, it then automatically returns to normal operation and the outputs are enabled again in accordance with the current system state. In order to detect any sporadic faults, the fault code readout remains enabled until it is reset by pressing Enter.

    7. How to Configure The configuration menu can be enabled in any of the module's operation statuses. All sensors integrated in monitoring activities, actuators, their switch positions and working speeds to be monitored are defined. The settings are made by the user directly on the module and, once saved, are stored in a non-volatile manner in a parameter record within the device.
