Replacing the memory module

Replace the memory module as follows:

  1. Consider the safety notes in chapter Creating a safe working environment.
    • Make sure the device is de-energized. The 400 V line voltage and the 24 V backup voltage must be disconnected.
  2. Loosen the screws and remove the electronics cover from the connection box.
  3. Remove the memory module from the old electronics cover.
  4. Compare the part number and the status of the memory module.

INFORMATION

The new memory module must have the same part number and the same (or a higher) status as the old memory module.
  1. Set the DIP switches on the new memory module in the same way as the control elements of the previous memory module.
  2. Insert the new memory module into the electronics cover.
  3. Place the electronics cover onto the connection box and screw it in place.
  4. Supply the device with voltage.
  5. Check the startup of the device.
    • If required, perform startup again or load the saved startup to the device.
    • For devices with safety card, check the startup of the safety card. For further information, refer to the product manual > chapter "Project planning for functional safety" > "Safety conditions" > "Startup requirements".
  6. Check the functionality of the new electronics cover.

If the device was ordered with the option /P "Parameters ex works", the customer-specific parameter set is saved on the supplied memory module upon delivery.

When ordering a new memory module using the part number, no data set is stored on the memory module.

  • Start up the device manually.
  • As an alternative, save the data set of a previously created data backup to the memory module. Start up the device with the saved data set.
