1 CHAPTER OVERVIEW
The Maintenance and Troubleshooting chapter provides details of how to maintain and troubleshoot products
based on the Px4x and P40Agile platforms. Always follow the w
arning signs in this chapter. Failure to do so may
result injury or defective equipment.
Caution:
Before carr
ying out any work on the equipment you should be familiar with the
contents of the Safety Section or the Safety Guide SFTY/4LM and the ratings on the
equipment’s rating label.
The troubleshooting part of the chapter allows an error condition on the IED to be identified so that appropriate
correctiv
e action can be taken.
If the device develops a fault, it is usually possible to identify which module needs replacing. It is not possible to
perform an on-site repair to a faulty module.
If you return a faulty unit or module to the manufacturer or one of their approved service centres, you should
include a completed copy of the Repair or Modification Return Authorization (RMA) form.
