Foreword
Micro Automation Sets are fully functional and tested automation
configurations based on A&D standard products for simple, fast and
inexpensive implementation of automation tasks for small-scale
automation. Each of the available Micro Automatic Sets covers a frequently
occurring subtask of a typical customer problem in the low-end
performance level.
The sets help you obtain answers with regard to required products and the
question how they function when combined.
However, depending on the system requirements, a variety of other
components (e.g. other CPUs, power supplies, etc.) can be used to
implement the functionality on which this set is based. Please refer to the

Fields of Application and Benefits
1.1 Automation
Task
On the event of a power failure in a shopping center the emergency lights and
other devices important to maintain the infrastructure are to be powered by a
generator.
A monitoring sensor is to be used to monitor the availability of the current network.
If it detects a power failure, a control unit requests power from the generator.
If a further monitoring sensor informs the control unit about the availability of the
generator current, it should trigger the network-circuit breaker to cut the main circuit
of the shopping center from the public grid.
After the power was cut from the public grid, the emergency power network of the
shopping center is to be connected to the generator.
This state is to be maintained until the first monitoring sensor signalizes that the
public grid is available again. As a result the control unit should then cut the circuit
breaker responsible for the emergency power supply from the emergency power
network of the shopping center.
After a successful disconnection from the emergency power network, the control
unit should switch the network circuit breaker on in order to supply the shopping
center with current from the public grid again. If this procedure is finished, the
control unit informs the generator to stop operation.
In order to guarantee a constant availability of the generator, its functionality has to
be checked once a month. To do so, the control unit should be able to switch the
network circuit breaker on/off in the manual mode using push buttons.
A mechanical interlock avoids the two circuit breakers being switched on at the
same time.

1.2
Automation solution Set 29
One circuit breaker of the type VL 160N connects the public grid to the main circuit
and one connects it to the emergency power system of the shopping center,
respectively.
Using the SIRIUS monitoring relay the availability of the three phases of the public
grid and of the emergency power system is monitored.
The LOGO! logic module disconnects the circuit breaker from the public grid if the
SIRIUS monitoring relay detects a phase error or a failure. It then triggers the
generator to switch on.
If the availability of the generator grid is confirmed by the SIRIUS monitoring relay,
the LOGO“ logic module cuts the circuit breaker to the generator grid.
If the SIRIUS monitoring relay signalizes that the public grid is available again, a
switch-back to the public grid and the switching off of the generator is triggered by
the LOGO! logic module.
The SITOP DC-UPS-MODULE ensures that the LOGO! logic module can operate
while switching between public grid and generator grid is carried out.
For maintenance purposes a knob switch is used to switch between automatic and
manual mode. Using a further knob switch, the circuit breaker on the one hand to
the public grid or on the other hand to the generator grid can be selected. Using a
push button it can be switched on or off.

The LOGO! Logic module is powered by an uninterruptible power supply
(UPS) (see “A1“and “A2“ in figure 2-1). While switching from grid to
generator and vice versa the battery buffers the LOGO! logic module.
The change-over contactor "R3“ connects the phase “L1” and the zero
conductor, depending on the availability of the generator between public
grid and generator grid, with the power supply “A1” and with the servo
motor of the circuit-breaker. As soon as the generator grid is available the
relay switches from the public grid to the generator grid.

The transfer switch is controlled by a LOGO! logic module “A1“ and by an
expansion module DM8 “A2“. The SIRIUS monitoring relay monitors the
availability of the public grid or of the generator grid, respectively. Both
monitoring relays transmit the state via a digital signal to the LOGO! logic
module.
The knob switch “S1“ is responsible for selecting the operation mode. Using
this switch the operation modes “automatic” and “manual” can be selected.
If the “manual“ mode is selected, the knob switch “S2” is used to address
the circuit-breaker either to the public grid or to the generator grid. The
push button “S3“ is then used to switch the selected circuit-breaker on, the
push button “S4“ is used to switch it off again..
An error triggered by exceeding the timeout counter for instance, has to be
acknowledged by the push button “S5”.

The circuit breakers are operated via the LOGO! logic module. In order to
avoid both circuit breakers to be switched on at the same time, the digital
activation command has been looped to the circuit breaker “R1” (“R2”)
using an auxiliary contact to the circuit breaker “R2” (“R1”).
The servo motors of the circuit breakers are powered analogically to the
UPS via the currently available grid using the change-over contactor “R3”.
This enables both circuit breakers to be controllable even in the case of a
power failure in one of the grids.

mechanism of the circuit breaker is activated
and it takes the position “triggered”.
4. Auxiliary
switch
This installation set comprises a NC and a NO.
The position of the auxiliary switches represents
the state of the circuit breaker.
• The NO-state provides the LOGO! logic
module with the current position of the
circuit breaker.
• The NC is used for locking purposes in
order to ensure both circuit breakers not to
be switched on at the same time.
5. Alarm
switch
This installation set comprises a NO. If this
alarm switch is closed it sends a signal to the
LOGO! logic module saying that the circuit
breaker has taken the switch position
“triggered”.
The 3 states of the circuit breaker
The circuit breaker can be in 3 different positions

No.
Switch position
1. Closed
In this position the contacts of the circuit breaker
are closed The load is connected to the grid and
the current can flow.
2. Open
In this position the contacts of the circuit breaker
are open. The load is disconnected from the grid
and the current cannot flow.
3. Triggered
In this position the contacts of the circuit breaker
are open. The switch position “triggered“ can be
attained either with a mechanism directly activated
on the circuit breaker, or it is triggered via an
optional module (e.g. shunt trip).
After the circuit breaker was brought into the
“triggered” switch position, it cannot immediately
be switched on again. In order to switch the circuit
breaker on again, in other words to close it, it first
of all has to be opened. This is to avoid the circuit
breaker to be switched on after an error (e.g.
short-circuit after in public mains) without having
corrected the error.

SIRIUS Monitoring relay
The monitoring relay 3UG4617 monitors the phase sequence and a phase
failure of one of the phases. It furthermore monitors if a set voltage is
undershoot or exceeded and if a set asymmetry value is exceeded and it
monitors the difference between the highest and lowest phase voltage in
relation to the highest phase voltage (Ux-y max - Ux-y min) / Ux-y max in a
3-phase grid.
If the correct phase sequence at the terminals L1-L2-L3 is applied, the relay
A4 or A5 picks up. This is depicted on the display with a relay symbol. In
case of an incorrect phase sequence the relay will not pick up. In this case
no error message will occur on the display but the relay symbol will not
show up! If the monitored voltage (Ux-y) is higher then the specified lower
voltage value (U|) and lower then the specified higher voltage value (Ux),
meaning within the voltage limits, and if the grid voltage (Asy) is lower then
the specified value, the relay A4 or A5 (contact 11-12-14) will pick up
approx. 50ms after the reaction of A4 or A5, respectively. For the
3UG4617 the display shows the current voltage between lines L1 and L2.
The following grid faults are depicted on the display as diagnosis message
with flashing symbols:
• Failure of one phase (3UG4618 or failure of the zero conductor).
Symmetric (all 3 phase voltages / star voltages at the same time)
• Asymmetric (only one phase voltage / star voltage) undershoot or
exceeding of the voltages specified in the menu. Exceeding the
asymmetry specified in the menu.
In case of a phase failure the relay A4 or A5 will immediately be released.
In case of the errors voltage undershoot, voltage exceed or asymmetry
exceed the relay A4 or A5 will be released after the specified fault display
relay time (Del).

4.3 SITOP
UPS
Function
In combination with the SITOP battery modules the DC-UPS-module 6 is
used to buffer parts of the load current (max. 6A) of 24V-load current
supplies of the SITOP series.
The loads to be buffered are powered by the voltage of input using the
outputs “Output L+” and “Output M” of the DC-UPS module. If the 24V
DC-supply voltage fails or if the voltage drops below the specified cut-in
threshold, the loads are powered by switching on the battery module which
is kept in full charge in stand-by parallel operation.

Cut-in threshold
If the input voltage drops below the specified value of the cut-in threshold,
the UPS-module will switch to backup power operation. The loads are then
only powered by the battery module.
End-of-charge voltage
The end-of-charge voltage depends on the type of the battery used and of
the temperature the battery is exposed to. For detailed information on the
adjustment please refer to the manual.
Charging current
The battery module is charged with constant current until the specified end-
of-charge voltage is reached. The charging process is then stopped.
Buffering time
The buffering time can be set in 10 second steps from 5 seconds to 635
seconds. Using switch 1 (specified time/maximum time) you can select if
the backup power operation is stopped when the specified time is reached
or when the exceed discharge threshold of the battery (= maximum
buffering time) is reached.

Switching from public grid to generator grid
The switching process is based on the status diagram from figure 4-1. The
application is in state “P1” and has the following basic conditions:
• Selector switch for operation mode “S1”: “Automatic”
• Circuit breaker switch “S2”: “0“
• Public grid connected to load
• Generator is switched off
• Locking switch of both circuit breakers is in “auto” position
Switching into state „P3“ is effected, if the SIRIUS monitoring relay „A4“
sends a message to the LOGO! logic module stating that the public grid
has failed for at least 10 seconds. The LOGO! logic module then switches
the grid circuit breaker „R1“ to the state „triggered“ and, in doing so,
interrupts the connection between load and public grid. An inquiry in form of
a digital signal is simultaneously sent to the generator. If the SIRIUS
monitoring relay „A5“ transmits the information on the availability of the
generator grid to the LOGO! logic module “A6” the generator circuit breaker
“R2” switches from ”triggered” to “open” (motor loads the spring force
storage device). Then the circuit breaker „R2“ is closed (spring force
storage device is unload). Now a connection between generator grid and
partial load (loads for emergency light, lifts, etc.) is established.
After the successful switch to the generator grid the state “P2” is attained.
Here the SITOP DC-UPS-MODULE “A2” ensures that the LOGO! logic
module “A6” is supplied with power even during the switching process from
public grid to generator grid.
If the switching process could not be carried out during the monitoring time
of 30 seconds, error state “P5” is attained. This situation is depicted on the
display with an error message. For safety reasons the LOGO! logic module
“A6” switches both circuit breakers “R1” and “R2” to the state “triggered”.
This means that the load is disconnected from the public and from the
generator grid. State “P6” is attained.

Switch back from generator grid to public grid
The switching process is based on the status diagram from figure 4-1. The
application is in state “P2” and has the following basic conditions:
• Selector switch for operation mode “S1”: “Automatic”
• Circuit breaker switch “S2”: „0“
• Public grid is disconnected from load
• Generator is switched on and connected to partial load
• Locking switch of both circuit breakers is in “auto” position
Switching into state “P4“ is effected if the SIRIUS monitoring relay “A4“
sends a message to the LOGO! logic module stating that the public grid
has returned for at least 10 seconds. The LOGO! logic module then
switches the generator circuit breaker “R2“ to the state „triggered“ and, in
doing so, interrupts the connection between partial load and generator grid.
After successful disconnection the LOGO! logic module effects a state
change of the grid circuit breaker “R1” from “triggered” to “open” (motor
loads spring force storage device). Then the circuit breaker “R1“ is closed
(spring force storage device is unload). Now the connection between the
public grid and the load is re-established.
After the successful switch to the public grid state “P1“ is attained again.
Here the SITOP DC-UPS-MODULE “A2” ensures that the LOGO! logic
module “A6” is supplied with power even during the switching process from
public grid to generator grid.
If the switching process could not be carried out during the monitoring time
of 30 seconds, error state “P5” is attained. This situation is depicted on the

4.5 Service
functions
Manual control of the circuit breakers via application buttons
For maintenance purposes both circuit breakers can manually be opened
or closed. To do so the following settings have to be carried out.
• Operation mode switch “S1” “Manual”
• Circuit breaker switch “S2”: “Public grid” or “Generator”
The closing of the circuit breaker is effected by pushing the green push
button “S3”, if the spring of the motor has been tensioned in advance. If the
spring has not been tensioned, the circuit breaker remains in “triggered”
state, meaning no connection between load and power supply is
established.
The opening of the circuit breaker selected and the winding up of the
tension spring is carried out after the red button “S4” was pushed.
Service with onboard-control elements of the circuit breaker
If the selector switch is set to the “Off”-position, all outputs of the LOGO!
logic module are switched to “0”.
For the purpose of a function test of the circuit breaker it can also be
directly controlled via the control elements.
• In order to ensure that the LOGO! Logic module does not carry out
changes in the control outputs while the onboard service, the operation
mode switch “S1” has to be set to “0”
• The locking switch of the circuit breaker has to be set to “manual”
according to figure 4-7
Pushing the red onboard button “ON” effects the closing of the circuit
breaker if the spring was tensed before. If the spring is untensed, the circuit
breaker remains in the “triggered“ state.
Pushing the black onboard button “OFF” effects the opening of the circuit
breakers and the tensing of the spring.
Note
After the service operation has been finished the locking switch of the
circuit breaker has to be reset to “auto” again.
!
DANGER
Do not use this function if the public grid and the generator grid are
both available at the same time, as the circuit breakers do not
interlock each other when switched on. If both grids are connected
to the load at the same time, a short-circuit can occur!
