B90 LOW IMPEDANCE BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 7-11

• Description of problem: There is a problem with the Compact Flash memory in the CPU module.
• How often the test is performed: On relay power-up and afterwards once every 24 hours.
• What to do: Contact the factory.
• Description of problem: Seen until the builds is tagged as being 'release candidate' or 'gold' builds.
• What to do: Update firmware to either of these builds.
• 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.
