3.6.3. Delay / integrator (Delay)
A. Application
General purpose timer for
· integration of pulsating binary signals to obtain a continuous
signal, e.g. output of the loss-of-excitation function (out-of-
step protection) or reverse power protection
· extension of short I/P signals (pulse prolongation)
· simple time delay.
B. Features
· I/P channel and blocking input assignable to
· binary I/P signals
· protection function output signals
· I/P channel and blocking input can be inverted.
· adjustable reset time
· 2 types of time delay
· Integration: Only the time during which the I/P signal is at
logical "1" counts at the end of the time delay.
· No integration: The total time from the instant the timer
starts until it is either reset or expires counts.
C. Inputs and outputs
I. C.t./v.t. inputs:
· none
II. Binary inputs:
· input signal
· blocking
III. Binary outputs:
· pick-up
· tripping
IV. Measurements:
· time from the instant the timer starts.
