2.1. Intended use

Changeover devices are used everywhere there is dependence on high availability from the power supply. The ATICS® transfer switching device is intended for the application described in the chapter "System description". When the preferred supply fails, the ATICS® automatically switches to the second supply.

Areas of application:

 Group 1 and 2 medical locations according to DIN VDE 0100-710 and IEC 60364-7-710  Hospital main distribution boards (DIN VDE 0100-710)  Locations open to the public (DIN VDE 0100-718)  Emergency power supplies  Heating, air conditioning, ventilation, cooling  EDP, computer centres  Fire extinguisher and sprinkler systems

Several versions of the ATICS® are available. They differ for example by changing over from the two or four-pole systems or by the load current (see chapter "ATICS® tasks" on page 15). Please heed the limits of the area of application indicated in the technical specifications. Use which deviates from or is beyond the scope of these technical specifications is considered non-compliant. In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Intended use includes following all the instructions in the operating manual and complying with the test intervals.

2.2. Skilled persons

Only appropriately qualified personnel may work on Bender devices. Persons who are familiar with the assembly, commissioning and operation of the equipment and have undergone appropriate training are considered skilled persons. Such persons must have read this manual and understood all instructions relating to safety.

2.3. Device-specific safety instruction

Failure to adjust the settings may result in malfunction.

The settings must be changed in order to adapt the ATICS® transfer switching device to the existing equipment. When doing so, follow the instructions in chapter "5. Commissioning, settings and testing“.

Functional safety according to IEC 61508 can only be guaranteed when used properly.

MEDICS® includes::

 AC and 3(N) AC changeover and monitoring modules. Examples of modules in the MEDICS®

system include UMC..., USC..., UFC... and EDS.... insulation fault location systems.

 Display and operating units such as alarm indicator and operator panels or alarm indicator and test

combinations.

 Communication between these components takes place via the BMS bus (two-wire connection).  The connection of third-party technical equipment by means of protocol converters (gateways), via

digital inputs and relay outputs.

The real strength of MEDICS® is to be found in communication between all involved components and the resulting information provided to the user. Readiness for operation is monitored constantly; and operating states, irregularities, faults and equipment failures are displayed. From the user's point of view, this means high operational reliability.

In each case you should make the settings that are required for adaptation to the application case in question and local conditions.

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.

Typical time diagrams can be found in the following chapters of the ATICS® switch user manual TGH1443 issued by Bender GmbH.

TGH1443, chapter 3.5.1.1 Time diagram: Changeover between the preferred and redundant line Example: Line 1 is set as the preferred line.

TGH1443, chapter 3.5.1.2 Time diagram: Staggered switching after total power failure The external ATICS-ES energy storage device (optional, see "Ordering information") is required for the staggered switching. If there is no voltage on either of the power supplies, the ATICS® switches to position "0". When the power is restored, the ATICS® switches on the supply again with the set delay time T(start). Example: Line 1 is set as the preferred line.

TGH1443, chapter 3.5.1.3 Time diagram: Changeover to generator mode

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).
