(Trip Time Delay)
•
Time delays are selectable from 1 to 9 cycles, in
increments of 1 cycle, based on 60 Hz. For 50 Hz
systems, multiply the number of cycles by 0.83.
•
The high-current trip time delay should be set faster
than the normal time current curve. If the high-current
trip is set slower, actual timings will be faster than
the high-current trip time programmed.
•
Use the PHASE/GROUND key to examine phase or
ground.
