3.4.The automatic changeover module UMA710…
3.4.1. The transfer switching device
If the preferred supply fails, the ATICS® ensures 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
In the normal condition (fault-free operation) the preferred supply is connected. The 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 supply" is reconfigured to the other line
The ATICS® switches 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
- or immediately after pressing the "RESET" button or when the redundant line fails (even when the
switching-back interlocking function is enabled)
–the setting "Preferred supply" is reconfigured to the other line
–the digital input is configured to "TEST" and this input is reset
–a transfer switching device test is enabled and the test time has expired
With the optional ATICS-ES energy storage device only: The ATICS® changes to switch position
"0" and stays there if the following conditions are simultaneously met:
–Line1 and Line 2 have failed
–Automatic mode is set
–No short-circuit is present downstream of the transfer switching device
–The setting "Load disconnection" is set to "on" and the external ATICS-ES energy storage device
is connected
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-calculation and the requirements of DIN
VDE 0100-710 (VDE 0100 Part 710) Section 710.537.6 automatic changeover devices (see
also 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, 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 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. 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.

3.4.2. Insulation monitoring of the IT-System
Insulation monitoring
The integrated insulation monitoring device measures the insulation resistance on AC IT systems, which
may also contain DC voltage components. Adaptation to the system leakage capacitances occurs
automatically. The measuring time increases as the system leakage capacitances increase.
Load current measurement
The load current on the IT system is measured using an STW2 measuring current transformer.
Temperature monitoring
The temperature in the transformer winding is measured via PTC thermistors.
Evaluation
If any of the measured values does not fall within the limits, an alarm is triggered. A message 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.
Locating current injector
When an insulation fault is detected on an IT system, the integrated locating current injector generates
a defined locating current signal to locate the insulation fault. The locating current is limited to
1 mA. This feature can be switched on or off (see chapter "7.4.4.4 Settings menu 4: IT system").
The locating current flowing between the IT system and earth can cause controller faults in
sensitive parts of the system, such as the PLC or relay. It must therefore be ensured that the
locating current is compatible with the monitoring
3.4.3. 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.
The ATICS® also continuously monitors:
The switch position of the switch and coils 1 and 2 of the switch
Power supplies 1 and 2, which supply the electronics from the systems concerned
Internal microcontrollers and memory modules
Important connecting wires, such as:
–Measuring current transformer connection
–Temperature sensor connection
–Power supply and PE connection
For alarm and test combinations, and alarm indicator and operator panels, device failure
monitoring can also be programmed via the BMS bus (necessary for functional safety).
On systems with generator: total power failure possible
If the preferred line fails, the ATICS® starts the generator which is 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, the ATICS® cannot check the redundant line.
Therefore, regularly test the generator and the changeover function to make sure they are
working properly (see checklist in the Appendix to this manual).

UMA710-2-xx-ISO-xx, Manual.docx Issued: 11.Jan.2016 15
3.4.4. 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 the 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. Optionally, the external ATICS-ES energy storage device can be connected to supply
the two coils and the electronic system. It is then possible to change over to switch position "0". If several
ATICS® are installed on one system, they can be switched to the preferred line one-by-one starting from
switch position "0" on voltage recovery. This prevents peak loads occurring which would otherwise occur if
the lines of several transfer switching devices were switched on simultaneously.
3.4.5. Manual mode
In manual mode, changeover can be achieved using an Allen key. The changing over to switch position "0"
can be locked with a padlock.
3.4.6. Bypass mode (optional)
By using the optional bypass switch (S1) the changeover and monitoring module can be set into the bypass
mode. In this case the switch will bypass the ATICS® (N1) unit. The ATICS® switch can then be tested or
replaced without power interruption downstream to the changeover and monitoring module.
Only skilled persons may work or operate the changeover and monitoring module. Skilled
means, persons who are familiar with the assembly, commissioning and operation of the
equipment and have undergone appropriate training. Such persons must have read this manual
and understood all instructions relating to safety.
Please refer to the chapter “operation of the bypass mode”.
