Time Delays
The time delay T DELTA PHI (address 4603) should be left at zero, unless you wish to transmit the trip indi-
cation with a delay to a logic (CFC), or to leave enough time for an external blocking to take effect.
After expiry of the timer T RESET (address 4604), the protection function is automatically reset. The reset time
depends on the decoupling policy. It must have expired before the circuit breaker is reclosed. Where the auto-
matic reset function is not used, the timer is set to ∞. The reset signal must come in this case from the binary
input (circuit breaker auxiliary contact).
The timer T BLOCK with reset delay (address 4607) helps to avoid overfunctioning when voltages are connect-
ed or disconnected. Normally the default setting need not be changed. Any change can be performed with the
DIGSI communication software (advanced parameters). It must be kept in mind that T BLOCK should not be
set less than the measuring window for vector jump measurement (150 ms).
2.9.3 Settings
Addresses which have an appended "A" can only be changed with DIGSI, under "Display Additional Settings".
