During tens of hours of synchronizing the device will learn its average error and starts to make small corrections by itself The target is that when the next synchronizing message is received the deviation is already near zero Parameters AAlntv and AvDrit will show the adapted correction time interval of this 1 ms auto adjust function Time drift correction without external sync If any external synchronizing source is not available and the system clock has a known steady drift it is possible to roughly correct the clock error by editing the parameters AAIntv and AvDrit The following equation can be used if the previous AAlIntv value has been zero 604 8 AAIntv DriftInOneWeek If the auto adjust interval AAIntv has not been zero but further trimming is still needed the following equation can be used to calculate a new auto adjust interval 1 1 DriftInOneWeek AADU previous 604 8 AAN yew The term DriftInOne Week 604 8 may be replaced with the relative drift multiplied by 1000 if some other period than one week has been used For example if the drift has been 37 seconds in 14 days the relative drift is 37 1000 14 24 3600 0 0306 ms s V265M EN M A004 121 6 5 System clock and 6 Supporting functions synchronization Example 1 If there has been no external sync and the relay s clock is leading sixty one seconds a week and the parameter AAlntv has been zero the parameters are set

6. The benefits of this scheme is that only one digital inputs is needed and no extra wiring from the relay to the circuit breaker CB is needed Also supervising a 24 Vdc trip circuit is possible The drawback is that an external resistor is needed to supervise the trip circuit on both CB positions If supervising during the closed position only is enough the resistor is not needed e The digital input is connected parallel with the trip contacts Figure 10 6 1 1 e The digital input is configured as Normal Closed NC e The digital input delay is configured longer than maximum fault time to inhibit any superfluous trip circuit fault alarm when the trip contact is closed e The digital input is connected to a relay in the output matrix giving out any trip circuit alarm e The trip relay should be configured as non latched Otherwise a superfluous trip circuit fault alarm will follow after the trip contact operates and the relay remains closed because of latching e By utilizing an auxiliary contact of the CB for the external resistor also the auxiliary contact in the trip circuit can be supervised e When using the dry digital inputs DI7 using the other inputs of the same group sharing a common terminal is limited e When using the wet digital inputs DI1 DI6 an auxiliary relay is needed 177 10 6 Trip Circuit Supervision 10 Applications 178 Using optional DI19 DI20 Note In the device only the optional
