    When the operating temperatures inside the devices are lower, the required maintenance intervals are increased accordingly. Replacement of the maintenance-related components named above is not possible without soldering. Maintenance work must be carried out by AREVA service personnel only. Routine functional testing The C232 is used as a safety device and must therefore be routinely checked for proper operation.
  • Page 190 11 Maintenance (continued) In addition, a dynamic test can be used to check transmission performance and the phase relation of the current transformers and the anti-aliasing filter. A dynamic test is not absolutely necessary, since it only checks the stability of a few less passive components.
