Connection to Power Supply and CAN Bus

 

Use in potentially explosive atmospheres!

For use in a potentially explosive atmosphere, it is essential that you observe the information in section Use in Potentially Explosive Atmospheres.

   

Operational safety!

The proper functioning of the device is only guaranteed if the device is operated within the permissible supply voltage range. Therefore, use a power supply in accordance with the specifications in the operating manual.

   

Grounding of the CAN bus shield

The CAN bus shield is usually grounded via the PowerView3. For further information, refer to the PowerView3 operating manual.

The TempScan20 is connected to the power supply and the CAN bus via the supplied mating plug for power supply/CAN bus DEUTSCH® DT06-08SA. For the connection to the power supply, use a cable with a conductor cross-section of at least 0.5 mm2 and a maximum length of 10 m (32').

Make the connection as follows:

  1. First slide the supplied protective cap for the power supply/CAN bus harness loosely onto the shared power supply/CAN bus harness.
  2. Connect the power supply and the CAN bus to the mating plug using the supplied contacts. If needed, also connect the CAN bus shield (e.g. when the CAN bus shield is not to be grounded via the PowerView3). A special crimping tool is available from MOTORTECH for connecting the wires. Observe the assignment of the power supply and CAN bus connector at the TempScan20 (see illustration above). Connect CAN Com to CAN/RS232 Shield.
  3. Secure the contacts in the mating plug with the supplied wedge lock.
  4. Close the unused openings of the mating plug with one of the supplied sealing plugs by inserting the sealing plug up to the head into the respective opening.
  5. Slide the protective cap onto the mating receptacle.
  6. Make sure that the thermocouples are connected (see section Connecting Thermocouples).
  7. Plug the mating plug into the power supply and CAN bus connector of the TempScan20.
