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
min
imum values: The value to be parameterized must be at least 7%
greater
.
For
max
imum values: The value to be parameterized must be at least 7%
smaller
.
Example:
t1min shall be set to 30 s
Calculation:
30 s + 7% = 32.1 s
Value to be parameterized: Must be equal to or
greater
than the calculated value
(e.g. 32.34 s)
Example:
TSAmax. shall be set to 5 s
Special case here:
TSA is set directly via the change of t3n using the following formula:
t3n = TSA – 0.7 s
Calculation:
5 s – 7% = 4.65 s
t3n = 4.65 s – 0.7 s = 3.95 s
Value t3n to be
parameterized:
Must be equal to or
smaller
than the calculated value (e.g. 3.822 s)
