System description

The factory settings guarantee a changeover period of t = 0.5 seconds and switching back within 10
seconds when voltage is restored on the preferred supply. Therefore, the ATICS® can be used in IT
systems with a requirement for a changeover period t
≤
0.5 s (IT systems with operating theatre
lights, endoscopic field illumination in operating theatres or other essential sources of light, etc.).
When there is a short-circuit downstream of the transfer switching device, the transfer switching de-
vice must not continually change back and forth between the two lines. This can occur when the
short-circuit current is small and the transfer switching device switches faster than the short-circuit
breaker trips. The ATICS® monitors the load current downstream of the transfer switching device in
order to detect a possible short-circuit. If the preferred line fails and a short-circuit current is detected
at the same time, the ATICS® does not change over immediately but only once the circuit breaker has
tripped.
If the ATICS® detects a supply failure or a fault, an alarm appears on the LCD, the "ALARM" LED lights
up, the alarm relay trips (if set) and this alarm is forwarded to other Bender devices (such as an alarm
indicator and test combination) via the BMS bus.
Phase sequence direction errors are recognised and indicated on the LC display. Even though ATICS®
switches over to the redundant line.
May malfunction if delay times are not adjusted
The response delay t(on), the return transfer delay time t(2->1), the delay on
release t(off) and the dead time t(0) of the ATICS® are adjustable and must be
adjusted to the requirements of the specific case, the short-circuit-calcula-
tion and the requirements of DIN VDE 0100-710 (VDE 0100 Part 710) for au-
tomatic changeover devices (see chapter "Commissioning, settings and
testing").
