DIF HW<->ORDER CODE:
MATCH HW&ORDER CODE
• Description of problem: The "B90 Function" setting is set to "Protection" and there is a discrepancy between the order
code and the hardware (HW) configuration. For example, if the software option in the B90 order code assumes 24
feeder configuration, but there are only two DSP modules with a total of 16 CT inputs, there is a discrepancy between
the hardware and order code and if the "B90 Function" is set to "Protection" the relay asserts this self-test.

• Latched target message: No.
• How often the test is performed: On relay power-up and every time the "B90 Function" setting is changed.
• What to do: Check that the hardware configuration (number and type of DSP modules) matches the software option in
the order code.
