• Range H: The Reset pulse interrupts the run down of the time and sets the elapsed time to 0.
If the trigger coil is activated again whilst the off-delay time is running down,
the off-delay time is stopped.
Retriggering during the off-delay
In on-delay and off-delay mode, the behavior of the timing relay when it is
retriggered during the off-delay depends on the parameter setting and the
actual value t:
•
setpoint value I1 ≧ reference value I2
If the trigger coil is activated again, the actual time t is stopped. The off-delay
time does not run down until the trigger coil drops out.
•
Setpoint value I1 < Setpoint value I2
•
Actual time t < Setpoint value I1
If the trigger coil is actuated again, the actual time t is stopped. The off-delay
time does not run down until the trigger coil drops out.
•
Actual time t ≧ Setpoint value I1
If the trigger coil is actuated again, the actual time t is set to 0. If the trigger
coil subsequently drops out, the set off-delay time is run down again.
This behavior is also the same for on-delay and off-delay modes with random
switching.
