Page 36 6 F 2 S 0 7 5 7 3.3 Automatic Supervision 3.3.1 Basic Concept of Supervision Though the protection system is in a non-operating state under normal conditions, it waits for a power system fault to occur at any time, and must operate for the fault without fail. Therefore, the automatic supervision function, which checks the health of the protection system during normal operation, plays an important role.
Page 37 6 F 2 S 0 7 5 7 • Setting value monitoring: Checks discrepancies between the setting values stored in duplicate. Watchdog Timer A hardware timer that is cleared periodically by the software is provided, which checks that the software is running normally. DC Supply Monitoring The secondary voltage level of the built-in DC/DC converter is monitored, and is checked to see that the DC voltage is within a prescribed range.
Page 38 6 F 2 S 0 7 5 7 If the trip supply is lost or if a connection becomes an open circuit, then the binary input resets and TC FAIL is "0". Figure 3.3.2 shows the scheme logic. A trip circuit fail alarm TCSV is output when TC FAIL is "0".

The circuits that can not be supervised are binary input and output circuits and human interfaces. Therefore, regular testing is minimised to checking the unsupervised circuits. The test procedures are the same as described in Sections 6.4.1, 6.4.2 and 6.4.3.
Page 109 6 F 2 S 0 7 5 7 If no message is shown on the LCD, this means that the failure location is either in the DC power supply circuit or in the microprocessors. If the "ALARM" LED is off, the failure is in the DC power supply circuit.
