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.
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)
tw Waiting time t4 Interval between ignition «Off» and «BV2»
TSA Safety time t8 Postpurge time
t1 Prepurge time t10 Specified time for air pressure signal
t1´ Purge time t11 Programmed opening time for actuator «SA»
t3 Preignition time t12 Programmed closing time for actuator «SA»
t3n Postignition time t22 2nd safety time
1) Maximum running time available for actuator «SA». The actuator’s running time must be shorter
2) Repetition (maximum number of startups per controlled start)
3) Only AC 230 V
