Time delay
t(pulse) Pulse time: 15 … 30 ms
t(0) Dead time
t(on) Response delay ALARM failure voltage line 1
Measuring time: approx. 50 ms
t(start) Switch-on delay after complete power failure and restart of the ATICS® Measuring time: approx. 50 ms
t(off) Delay on release ALARM failure voltage line 1 Measuring time: approx. 50 ms
t(off) Delay on release ALARM failure voltage line 2* Measuring time: approx. 50 ms
t(2->1) Return transfer delay time
t(GenStart) Generator start-up delay, delayed changeover to generator. Measured from voltage line 2 ok
t(GenOff) Generator disconnecting delay time, delayed switching-off of the generator
t(GenMax) Generator start-up time. Time until generator supplies correct voltage. The message "Failure line 2" is suppressed until then.

* 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.
