ATICS-2-63A-ISO
3.3.2 Application example intensive care unit
• ATICS-2-63A-ISO: Changeover between
the preferred and redundant line while
monitoring the medical IT system with
transformer load and temperature
monitoring
• EDS151: Insulation fault locator for fast
insulation fault location (recommend-
ed)
• ATICS-BP: Bypass switch for uninter-
rupted test/maintenance (recommend-
ed)
• MK2430/MK800/TM800/CP9xx: Alarm
at at least two points with independent
power supplies for functional safety
3.4 ATICS® tasks
The ATICS® automatic transfer switching and
monitoring device has the following tasks:
• Two-pole changeover of the power supply
• Voltage monitoring of the preferred supply (line 1)
• Voltage monitoring of the second supply (line 2)
• Voltage monitoring at the automatic transfer switching device output (line 3)
• Monitoring of the changeover switch for correct switch position
• Internal functional testing, including checking the switching times
• Monitoring of the insulation resistance in the IT system
• Monitoring of the IT system transformer load current
• Monitoring of the IT system transformer temperature
• Communication with remote MK... alarm indicator and test combinations, and with TM… or
CP9xx… alarm indicator and operator panels via BMS bus
• Option for adjusting the time delay for the changeover process according to DIN VDE 0100-
710
(VDE 0100 Part 710)
• Possible field of application in systems according to DIN VDE 0100-710 (VDE 0100 Part 710)
with a changeover period ≤ 15 s or even ≤ 0.5 s
