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. For automatic switching on at
staggered intervals, the ATICS® " -ES" version and the external ATICS-ES energy storage device (optional,
see chapter „Ordering information“ on p. 102) are required. If there is no voltage on either of the pow-
er supplies, ATICS® switches to position "0".
When power is restored, the ATICS® switches on the supply again with the set delay time t(start).
Manual method: 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 the 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 set value of t(off) is
ignored. If the voltage is too low, the ATICS® waits until the set time t(off) has elapsed.
