System description
3.5.1.2 Time diagram: Staggered switching after complete power failure
Switching on at staggered intervals after a complete power failure (no voltage on either of the power
supplies) prevents all loads from being switched on at the same time. Switch the ATICS® to position "0"
using an Allen key. When power is restored, the ATICS® switches on the supply again with the set delay
time t(start).
Example: Line 1 is set as preferred line.

After a complete power failure and restart of the ATICS®, t(off) and t(start) start simultaneously. The time
that is longer determines the behaviour. After switching on, the ATICS® performs a quick measurement
of the voltage with t(off) = 100 ms. If the voltage is within the permissible range, the value set for t(off)
is ignored. If the voltage is too low, the ATICS® waits until the set time t(off) has elapsed.
