Timer
Once activated, the timer activates the PICKUP output and the phase-specific PICKUP_X
output. The time characteristic is according to DT. When the operation timer has reached
the value set by
Trip delay time
, the TRIP output and the phase-specific TRIP_X output
are activated. If the fault disappears before the module trips, the reset timer is activated. If
the reset timer reaches the value set by
Reset delay time
, the trip timer resets and the
PICKUP output is deactivated.
The timer calculates the pickup duration value PICKUP_DUR, which indicates the
percentage ratio of the pickup situation and the set trip time. The value is available through
the monitored data view.
The BLOCK signal blocks the operation of the function and resets the timer.
