Information About Power Supply/Connection Module

Overview

  • The power supply (2) and the Lexium™ MC connection module (3) are installed in a cabinet (1).

  • The power supplies feed the Lexium™ MC12 multi carrier track. For each power supply, you must place a Lexium™ MC connection module between the power supply output and the Lexium™ MC12 multi carrier track.

    Up to a maximum of three power supply/Lexium™ MC connection module combinations can be used in parallel. If more than three power supplies are required, the track must be divided into power groups that are powered separately. For how to define power groups, refer to the different power interconnects (Lexium™ MC power interconnects / Power disconnector).

    The universal power supply ABLU3A48200 is designed to handle the back feed voltage (braking voltage) from the Lexium™ MC12 multi carrier track during the braking phase. Refer to Connecting a Braking Resistor (CN2).

  • The Lexium™ MC12 multi carrier track (5) is connected to the Lexium™ MC connection module with a pre-assembled cable (4).

    NOTE: If you have to remove a connector from the cable, for example, to lead the cable through a cable bushing, make sure to reconnect the wires of the cable correctly to the connector afterwards. Observe the requirements for the degree of protection and the EMC regulations.

    Refer to cable wiring diagram Pinout and Cable Diagram.

    NOTE: The front covers of the segments are not connected to the PE (protective ground/earth). The electrical safety requirements are fulfilled by appropriate insulation measures (protective separation).

  • The Lexium™ MC connection module supplies the Lexium™ MC12 multi carrier track with power (DC bus).

    The Lexium™ MC connection module limits the DC bus voltage to <60 Vdc, conforming to Functional Safety rules. Refer to Scope of Operation (Designated Safety Function).

  • You can feed the DC bus at different points of the track. For example, feed at points where a high electrical load due to deceleration and acceleration is to be expected.

  • The DC bus (up to 60 A) inside the Lexium™ MC12 multi carrier track is distributed from segment to segment via the Lexium™ MC power interconnects (6).

  • The Lexium™ MC12 multi carrier requires the power supply to be dimensioned based on the number of segments, segment groups, carriers, load and other relevant parameters.

    Each power supply/Lexium™ MC connection module combination must not exceed 24 segments.

    For how to dimension the power supplies, refer to System Planning.

  CAUTION
INOPERABLE EQUIPMENT
  • Do not connect the DC bus of the Lexium™ MC12 multi carrier track directly to the power supply.
  • Always connect the DC bus through the Lexium™ MC connection module.
Failure to follow these instructions can result in injury or equipment damage.

Also refer to Technical Data for Power Supply and Technical Data for Lexium™ MC connection modules.

For a controlled movement of the carriers on a track, the required hardware preconditions must be fulfilled. This includes the correct state of the DC bus (DC ok) and SFO (Safe Force Off) signals of segments and enabled logical devices (track, segments, carriers). You must monitor the required hardware preconditions in your application and implement adequate reactions for a controlled behavior of the devices.

 WARNING
UNINTENDED EQUIPMENT OPERATION
  • Monitor electrical I/O signals from peripheral devices like power supplies and connection modules in your application.
  • Permanently monitor the state of the track, the segments and the carriers in your application.
  • Trigger a controlled reaction of your application when deviations from the monitored preconditions are detected.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
