3.1 Properties
3.1.1 Product description
The ATICS® transfer switching devices provide all functions for changeover between two independent power supplies. The integration of both the electronic system and the switching elements in one
flat, compact device reduces space requirements in the switchgear cabinet, minimises the amount
of wiring, and reduces the fault probability. For maximum reliability, ATICS® was designed in strict
accordance with the guidelines for functional safety.
Connectors at all connecting wires in combination with bypass switches enable ATICS® to be tested
during ongoing operation. In case of need for service, it is possible to repair or replace the device
without interrupting the power supply. ATICS® considerably enhances the safety level in industry
and other sensitive environments like hospitals.
3.1.2 Changeover
Automatic changeover to the second (redundant) line on loss of the preferred supply or when
the values are outside the permissible voltage range
Voltage monitoring line 1/2 (input) and line 3 (output)

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, ATICS® ensures that the power supply is changed over safely.
The switch contacts are offset on a rotating shaft. This design prevents simultaneous switching of
line 1 and line 2. The switch has three positions:
1 Line 1 switched on
0 Both lines switched off
2 Line 2 switched on
Either line 1 or line 2 can be set as the preferred line (setting described in "Settings menu 1: Changeover" on page 69 or "Settings menu 5: Digital input" on page 75).
1. In normal operating condition (fault-free operation) the preferred supply is connected. ATICS®
will switch 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 reconfigured to the other line
16
ATICS-DIO_D00080_02_M_XXEN/08.2017
System description
WARNING
2. ATICS® will switch from the redundant line back to the preferred line if
– the voltage on the preferred line is restored
- the return transfer delay time t(2->1) has expired and no switching back interlocking
function is enabled
- immediately after pressing the "RESET" button or when the redundant line fails
(even when the switching back interlocking function is enabled)
– the setting "Preferred Line" is reconfigured to the other line
– the digital input is configured to "TEST" and this input is reset
– a test of the transfer switching device is active and the test period has elapsed
Failure to adjust delay times may result in malfunctions
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 ATICS® are adjustable and must be adjusted
to the requirements of the specific case, the short-circuit calculation and the requirements of DIN VDE 0100-710 (VDE 0100 Part 710) for automatic changeover
devices (see chapter "Commissioning, settings and testing").
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, 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 device 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. 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, ATICS® does not switch over immediately but only once the circuit breaker has
tripped.
If 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 so ATICS®
switches over to the redundant line.

3.5.1.2 Time diagram: Staggered switching after complete power failure
After a complete power failure (i.e. no voltage on either of the power supplies) it is often necessary
to switch to the supply at staggered intervals. This prevents all loads being switched on simultaneously. Switch ATICS® to position "0" using an Allen key. When power is restored, ATICS® switches on
the supply again with the set delay time t(start).
Example: Line 1 is set as the preferred line.

WARNING
3.5.2 Monitoring the device functions
The control circuits are designed in such a way that, even though it is almost certain that a particular
fault will occur, it cannot cause the power supply at the output of the automatic transfer switching
device to fail.
ATICS® tests the switch position of the switch as well as coils 1 and 2 of the switch once a day at 12:00
p.m.
ATICS® also continuously monitors:
Power supplies 1 and 2, which supply the electronics from the systems concerned
Internal microcontrollers and memory modules
Important connecting wires, such as the measuring current transformer connection
For alarm and test combinations and alarm indicator and operator panels, device failure moni-
toring can also be programmed via the BMS bus (necessary for functional safety).
For systems with generator: total power failure possible
If the preferred line fails, ATICS® will start the generator connected to the redundant line. If the generator does not start, the line downstream of the transfer
switching device will be dead.
When the generator is switched off, ATICS® cannot check the redundant line.
Therefore, regularly test the generator and the transfer switching device to make
sure they are working properly (see checklist in the appendix to this manual).
3.5.3 Power supply
The coils of the switching device are each supplied from the line which is not currently switched on.
This ensures that it is possible to switch to the redundant line if the preferred line fails, for example.
The power supply of the electronic system is of redundant supply from lines 1 and 2. This ensures
constant supply to the electronic system even when one line fails.
If both lines fail, the changeover switch remains in the last switch position. Switch ATICS® to position
"0" using an Allen key. When power is restored, ATICS® switches on the supply again with the set delay time t(start). If several ATICS® are installed in one system, they can be switched to the preferred
line one by one starting from switch position "0" on voltage recovery. This prevents the peak loads
that would occur if the lines of several transfer switching devices were switched on simultaneously.
3.5.4 Manual mode
In manual mode, changeover can be achieved using an Allen key. The switching device can be held
in switch position "0" and locked with a padlock.

4.2 Connection
4.2.1 Short-circuit protection
The choice of back-up fuses F should ensure both short-circuit protection for the transformer and selectivity for the overcurrent devices connected downstream in the IT systems.
The connecting wires between the automatic transfer switching devices and the overcurrent protective device downstream are to be laid so that they are short-circuit and earth-fault proof.
When choosing back-up fuses, keep to both the maximum permissible values laid down by the
guidelines which apply to the site of use and national and international standards to make sure that
the contacts do not weld.
For recommendations on the use of the appropriate fuse, refer to the nameplate of ATICS® and to
the ordering details in this manual.

WARNING
WARNING
Risk of fatal injury from electric shock
If any of the supplies are switched on, some of the parts of the system which are
not yet fully installed may be live.
Open the transparent cover of the
device for manual mode selection and
wait until the display shows "Manual
mode".
Turn the Allen key to switch position "0".
Leave the transparent cover open and
lock the transfer switching device with a
padlock to prevent it from starting accidentally.
Installation and connection
Risk of fatal injury from electric shock
Connecting wires can come loose and fall out if the ferrules being used are too
short, the wire ends are tinned or the connection screws have not been tightened
enough.
Consider a stripping length of 20 mm and do not use ferrules when connecting
lines 1, 2 and 3.
Note the assignment of the terminals. Note especially that the two supplies are
always connected to the device from the top.
Use a torque wrench to tighten the terminal screws.
Check all the screws on a regular basis to make sure they are seated tightly.
Risk of destruction when insulation and voltage test are carried out
-> Disconnect the device from the mains for the duration of the test.
Risk of destruction in the event of phase failure in three-phase systems
If only one of the phases fails, it may result in overvoltages which can damage
the connected devices.
-> Install a device for all-pole disconnection in the event of phase failure.
Risk of destruction if connected incorrectly
-> The terminals labelled GND must not be connected to PE.
