Note on parameterization:
Use the AZL2... or ACS410 to always set the exact value of the required time (multiples of increments of 0.147
seconds or 0.294 seconds).
When parameterizing minimum or maximum times, the possibility of a ±7% tolerance must be taken into con-
sideration.
For minimum values: The value to be parameterized must be at least 7% greater.
For maximum values: The value to be parameterized must be at least 7% smaller.

t1min shall be set to 30 s
30 s + 7% = 32.1 s
Must be equal to or greater than the calculated value
(e.g. 32.34 s)
TSAmax. shall be set to 5 s
TSA is set directly via the change of t3n using the following formula:
t3n = TSA – 0.7 s
5 s – 7% = 4.65 s
t3n = 4.65 s – 0.7 s = 3.95 s
Must be equal to or smaller than the calculated value (e.g. 3.822 s)
