The analog level value is by default in a reset state, when the value meets the comparison (inside or outside the
comparison band) the "Analog Level X" signal is activated if the analog value remains active the time set in the analog
delay setting. When the activation conditions are not met the "Analog Level X" value goes to the reset state.
An analog change must remain active at least 40 ms to be considered, plus the analog time setting. Besides the snapshot
event data has a 20 ms accuracy.
5.5.8 Maximum number of starts (66)
For F650 with firmware version below 7.XX, the special model F650 MOD003 relay incorporates a maximum number of
starts function (66) to prevent operators from jogging the motor (multiple starts and stops performed in rapid succession).
For F650 with firmware version 7.XX this element is included in standard models (No special model (MOD) is required)
A motor start is assumed to be occurring when the F650 measures the transition of the motor current from below 5% of
FLA to some value above 7% of FLA. Breaker status can also be used to detect motor starts. At this point, one of the Starts/
Hour timers is loaded with 60 minutes. Even unsuccessful start attempts are logged as starts for this feature. Once the
motor is stopped, the number of starts within the past hour is compared to the number of starts allowable. If the two
numbers are the same, a block occurs. If a block occurs, the lockout time is equal to the longest time elapsed since a start
within the past hour, subtracted from one hour.
