3.4 ATICS® tasks
The ATICS® automatic transfer switching device has the following tasks:
• Two-pole or four-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
• 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
3.5 The ATICS® functions
3.5.1 The automatic transfer switching device
If the preferred supply fails, the ATICS® ensures that the power supply is switched over safely.
The switch contacts are arranged offset on a rotating shaft. This design prevents simultaneous switch-
ing of line 1 and line 2. The switch has three positions:
1 Line 1 is connected
0 Both lines are disconnected
2 Line 2 is connected
Either line 1 or line 2 can be set as the preferred line (setting described in „Settings menu 1:
Changeover“ on p. 67 or chapter „Settings menu 5: Dig. input“ on p. 74).
1. In the normal operating condition (fault-free operation) the preferred supply is connected.
The ATICS® switches to the redundant line if:
– The preferred line fails
– The "TEST" button is pressed
– A digital input is configured to "TEST" and this input is enabled
– The setting "Preferred line" is changed to the other line
