The change of operating mode can be done by pressing the specific button for at least 0.5s. After this time, the new chosen modality will appear another display.
3.1 Reset mode (OFF-RESET)
•• In this mode the ATS looks over the lines status but it does not perform any changing actions.
•• Lines surveillance, measures display and status LEDs remain active. If the control of the switching devices is impulsive,
in OFF mode both open and close commands are disabled. If the command is in continuous mode, the behaviour can
be selected by P05.10.
•• Pressing the OFF-RESET button it’s possible to reset the retentive alarms, after removing alarm conditions.
To access the programming menu is necessary to activate the OFF mode.
3.2 Manual mode (MAN)
•• In MAN mode it is possible to manually control the devices. This operation could be done on devices Q1 and Q2 in functions of chosen line (line 1 or line 2). It is possible to select the switch to control by pressing the MAN key. On display
the device enabled (Q1 or Q2) appears. By pressing the ▲ or ▼ button it is possible to confirm the closing or opening
operation (the command will be received if the button is pushed for at least 300ms).

3.3 Automatic mode (AUT)
•• In automatic mode, the ATS checks permanently the lines and breakers status. Starting from the state of lines it performs
autonomously the closing/opening operations of breakers and the optional startup/shutdown of the generator set.
•• When the main line (S.Q1) exceeds the specified limits for a time higher the one set, the green LED C (line presence)
switches off giving a “threshold out” alarm. The ATS disconnects the load from S.Q1 and connects it to the S.Q2 (if it is
available and within admitted limits). After S.Q1 returns within the specified thresholds, the ATS moves the load on this
one after it has checked the stability and the quality of line. One time the changeover is finished, the ATS can provide
to the eventual cooling cycle of generator set (if it is programmed).
•• Automatic operating cycles vary both as a function of the type of application (Utility-Utility, Utility-Generator, Generator-Generator) and as a function of the type of devices used (motorized circuit breakers or contactors).
•• It is possible to program the unit to open the priority line S.Q1 before or after the secondary line S.Q2 has been made
available, through parameter P05.05 in the M05 “changeover” menu.
•• When the priority line S.Q1 turns within the established limits, the unit opens S.Q2 and switches the load on S.Q1. If on
S.Q2 is present a generator, the ATS provided to the eventual cooling cycle of it. It is possible also to lock the automatic
return to the priority line S.Q1 setting parameter P05.12. In this case it is necessary an external intervention to authorize
the turn of load to line S.Q1.
4. Power-up
•• The ATS can be supplied at 100-240VAC or 12-24VDC. In case of simultaneous presence of both power supplies, priority
is given to the AC power supply.
•• After first power-up the device normally starts in OFF/RESET mode.
•• During the normal work of ATS, if it switches off, when it will be switched on it comes to operating mode actives before
the switching off.
•• If it is necessary to modify this behaviour, the parameter P01.03 in the M01 “utilities” menu has to be changed.
•• The automatic transfer switch can be supplied with a second Vaux by means of the input “DC battery” from 12VDC to
24VDC. The same input could be used for the battery control, if it is activated. In this case it is necessary to set the correct battery voltage in the menu M05 “battery”.
•• During power-up all the LEDs blink in order to verify their operation.

8. Expandability
•• The automatic transfer switch can be expanded with additional modules. It is possible to connect a maximum of 2
expansion modules at the same time.
•• The expansion modules provide additional resources in order to extend the checking and managing chances. These
ones can be parameterized and managed through the dedicated setup menus.
•• The supported expansions modules can be grouped in the following categories:
- communication modules
- I/O modules
•• Procedure To add an expansion module:
-- remove the power supply to automatic transfer switch (230VAC and auxiliary in DC, if present);
-- remove the protecting cover of one of the expansion slots;
-- insert the upper hook of the module into the fixing hole on the left of the expansion slot;
-- rotate right the module body, inserting the connector on the bus;
-- push until the bottom clip snaps into its housing.
Fig. 30
•• Once expansion modules are installed, the ATS recognize them when it will be powered on. It automatically recognises
the kind of mounted expansions modules showing it on display.
•• At switching on, if the device configuration has changed compared to the last saved, (one module has been added or
removed), the ATS asks the user to confirm the new configuration. In case of confirmation, the new configuration will be
saved and will become effective, otherwise the mismatch will be shown at every subsequent power-on of the system.
Fig. 31 - Configuration change
N.B. One time the module has been installed, the associated functions have to be set by the user.

•• Internal variables (bit) are associated to inputs/outputs. For instance, it is possible to apply limit thresholds to the measurements done by the ATS. In this case, an internal variable named LIMx will be activated when the measurements will
go outside the limits defined by the user.
•• The following table shows all the I/Os and the internal variables managed by the automatic transfer switch with highlighting of their range (variables number per type).

•• Functions associated to the inputs are the 4 described in the above table.
•• LIMx: internal variable that identifies a limit value set by the user and managed by the ATS. Its status (active or not)
depends by out-of-limits of one measurement set by the user.
•• CNTx: internal counters that can count pulses coming from an external source (through a digital input INPx) or the
times that a certain condition has been verified.
Example: defining a limit threshold LIMx as count source, it will be possible to count how many times one measurement
has exceeded a certain limit.
•• REMx: allow the managing of remote variables.
•• UAx: allow the activation and managing of 4 programmable alarms.
9.1 Limit thresholds (LIMx)
•• The LIMx thresholds are internal variables whose status depends by out-of-limits of one measurement set by the user.
•• (example: phase to phase voltage L1-L2 higher than 400V).
•• The setting of thresholds value is calculated starting from a base value. Example: “400 V” adding a multiplicative factor
“x 1” →400 x 1 = 400V.
•• For each LIM, there are two thresholds: upper and lower.
N.B. The upper threshold must always be set to a value higher than the nominal one and the lower threshold must
always to be set to a value lower than the nominal one.
•• The control mode of thresholds can be done in 3 ways:
-- MIN function: when the value of selected measure is under lower limit, after the delay set, the threshold will be
activated. When the value of selected measure is over the upper limit, after delay set, the threshold will be restored.
-- MAX function: when the value of selected measure is higher than the superior limit, after the delay set, the threshold
will be activated. When the value of selected measure is under lower limit, after delay set, the threshold will be restored.
-- MAX+MIN function: when the value of selected measure is under lower limit or over the upper limit, after the delays
set, the threshold will be activated. When the value of selected measure comes back into the limits, the threshold will
be restored (if not retenitive).
•• The managing of limit can be done in 2 ways: with memory or without memory. In the first case the reset of the alarm
can be done only manually (retenitive); in the second case the reset of alarm is automatic, if the value comes back into
the limits. The setting can be done using the dedicated command in the “commands” menu.
•• See setup menu M13 “Limit thresholds”.

9.2 Remote-controlled variables (REMx)
•• The automatic transfer switch, with an external supervision software, can activate outputs (OUTx) via Modbus protocol
RS 485 channel. This can be done by means of remote variables REMx.
•• To use this functionality, it is necessary to use Modbus external module.
9.3 User Alarms (UAx)
•• User can set a maximum of 4 programmable alarms (UA1…UA4).
•• Conditions that generates the alarm can be different:
- In association of one thresholds LIMX set
- Activation of digital inputs INPx.
•• For each alarm, the user can define a message that will appear on the alarm page.
•• Properties of alarms can be defined by the user in the same way that normal alarms.
•• When several alarms are activated at the same time, they are displayed sequentially, and their total number is shown
on the status bar.
•• To reset one alarm that has been programmed with latch, use the dedicated command in the “commands” menu.
•• For details on alarm programming and definition, refer to setup menu M15 “User alarms”.
9.4 Counters (CNTx)
•• This function allows, by selecting a control channel, to activate a counter (see chapter M14 “counters”).
•• It is possible to count:
- Impulses acquired from inputs INPx;
- The numbers of activations of outputs OUTx;
- The overcome of limits LIMx;
- Activation of known variables.
•• The description of counters CNTx can be customized with a test of maximum 16 characters.
•• The unit of measure of counters Umn can be customized with a test of maximum 6 characters.

12. Automatic test
•• The ATS allows to the user to program a periodical control of generator start.
•• The automatic test is a periodic test carried out at specific intervals (interval managed on from “setup” menu). This test
can be done only if the ATS is in AUT mode and the function has been enabled.
•• It is possible to decide in which days of the week the automatic test can be executed and at what time of the day (hours;
minutes). See menu M09 “automatic test”.
•• After starting, the generators runs for a definite time, after which it will stop.
•• Before of generator starting the message “T.AUT”’ is displayed.
Fig. 40 - Automatic test
•• The automatic test can be enabled/disabled also without opening the “Setup” menu, directly from keyboard in the
following way:
- Open the “AUTOMATIC TEST” page and press the keys AUT and ▲to enable the function, or the keys AUT and ▼to
disable it.
•• The automatic test can be stopped with the OFF-RESET key.
•• It is possible to simulate the lack of the priority line by SW in order to verify the behavior of the transfer switch system.
•• The simulation can be started either using the “commands” menu (command C.16) or via a digital input, for example
connecting it to a key switch, programming the function of the input to the execution of the command C.16.
•• The simulation consists in considering the priority line absent for 2 minutes (even if it is actually present). During this
time the main page shows the message “SIMUL xxx” with the countdown of the time.
•• The simulation will cause the start of the generator (if present) and a load transfer exactly as in the automatic cycle.
•• It is possible to stop the simulation at any time by passing in OFF mode.
N.B. Doing the simulation through commands menu, user must start from the OFF mode (which allows access to the
menu). Once selected and confirmed the C.16 command, exit the command menu. The unit will independently switch
to AUT mode and it starts the simulation.

•• P05.01 – It defines the type of application
U-G = Utility to Generator
U-U = Utility to Utility
G-G = Generator to Generator
•• P05.02 – It defines which is the main line that is the line taking on the load when both sources are available.
•• P05.03 – Time from the opening of the Q1 device, after which the Q2 device closing command is given.
•• P05.04 – Time from the opening of the Q2 device, after which the Q1 device closing command is given.
•• P05.05 – OBP (Open Before Presence) means that, in automatic mode, the open command of a device is generated
when the line concerned goes beyond limits, irrespective of the status of the alternative line.
OAP (Open After Presence) means that, in automatic mode, the open command of a device is sent only after the alternative line is present within limits.
•• P05.06 – If, after sending an open or close command to a circuit breaker, this is not positioned correctly within this time
(feedback by means of OC contacts), alarms A03 or A04 are generated.
•• P05.07 – It defines whether open-close outputs must be continuously active (application with contactors or circuit breakers) or in pulse mode, i.e. activated until the device has been positioned as required. If in pulse mode, the command
is extended for a specified time (see P5.08 e P5.09) even after positioning completion.
•• P05.08 – Minimum duration of an opening command pulse. For the motorized circuit breaker application, it must be set
to a time long enough to allow the load of the springs. This time is considered also when working in continuous mode.
•• P05.09 – Duration of the closing command pulse.
•• P05.10 – It defines the behaviour of the open/close command outputs when working in continuous command mode
and the automatic transfer switch is in RESET/OFF mode. This parameter can be useful when working with contactors.
OFF – It opens the command outputs
NOC – No change on command output
•• P05.11 – If in automatic mode both sources are not available at the same time for a time exceeding P5.11, alarm A07
is generated.
•• P05.12 – If this parameter is enabled, after a transfer to the S.Q2, restoring to S.Q1 does not occur automatically when
the latter becomes available again, but it must be commanded in manual mode.
OFF – Disabled
ON – Enabled
•• P05.13 – Normal = This parameter is set in normal modality for default.In this modality the ATS manages in automatic
lines in function of quality and stability criteria set in menu “parameters”.
EJP (Effacement Jours Pointe) = in this modality, the ATS manage the lines in function of external signals that command the load transfer from the grid to the generator. This request is managed in two times using 2 programmable inputs set with the functions “Remote starting off load” and “Remote changeover” for EJP. When the starting of generator is
requested by means of closing of contact “remote changeover”, the starting generator delay starts (P05.14). At the end
the generator starts. After, when changeover command arrives, the ATS checks the status of generator and the load is
transferred. Load will be supplied by the generator until the changeover command input persists. When this command
lapses, the ATS prepares to transfer the load on the main line starting the cooling cycle of generator. The EJP function is
only enabled if the system is in automatic mode. The cutouts and alarms function as usual.
EJP-T = The EJP/T function is a simplified variation of the previous EJP, and in this case the engine start is controlled in
the same way, but a timer switches the load instead of an external signal. This function therefore uses only one digital
input, the starting input. The switching delay starts from when the programmable input INPx associated to the starting
command closes (parameter P05.15).
SCR = The SCR function is very similar to the EJP function. In this mode, the starting input enables genset starting as
for EJP, without waiting for start delay P05.14. The remote changeover input still has a switching go-ahead function
after “Changeover delay” P05.15.
•• P05.14 – Delay between the EJP start signal and the effective start signal sent to the generator.
28
•• P05.15 – Delay for switching the load from S.Q1 to S.Q2 in EJP and SCR mode.
•• P05.16 – If ON, in EJP , EJP-T and SCR mode, the load will not be switched back to the priority line in the case of a
generator failure, but only when the signals on the EJP inputs give a go-ahead.
•• P05.17 – If enabled, in case of closing failure of the switching device, in addition to the generation of the proper
feedback alarm (A03 or A04) the load is switched to the alternative source.
OFF = function disabled.
1 = check source S.Q1.
2 = check source S.Q2.
1+2 = check both S.Q1 and S.Q2.
•• P05.18 – In case of using of UVR in the changeover system controlled by ATS (parameter “UVR command” into menu
M11 “programmable outputs”) this parameter defines the period of deactivation of them to assure the immediate opening of devices)
•• P05.19 – Time between the opening pulse on the minimum voltage coil and the spring reload command.
•• P05.20 – In case of use of motorized breakers, this parameter defines in which operating mode the automatic transfer
switch must execute the closing retry cycle. The closing retry is executed in case the breaker fails to close because the
springs were not loaded. It consists of a complete opening and spring loading cycle, followed by the issuing of a new
closing command. If the breaker fails to close again, then the A03 or A04 feedback alarm are generated.
•• P05.21– P05.22 - P05.23 These parameters allow to implement a time rotation in G-G applications, switching the
priority between the two generators. P05.21 defines the rotation interval between the two generators. The time of the
day when rotation will occur is defined by P05.22 and P05.23. If the rotation interval exceeds 24h, then rotation always
occurs at the time stated every n days. Contrarily, if it is less than 24h, then it occurs at the time specified and every
n-hours. For instance, if you set time at 12:30 and rotation every 6h, there will be a changeover at 12:30, one at 18:30,
one at 0:30, etc.
14.6 Description of “Voltage control line 1 S.Q1” menu
In this paragraph control parameters, thresholds setting and control levels of power sources defining acceptability criteria
are described. In this menu is also possible set the insensibility level to micro interruptions using parameter P06.10 (standard value 100ms). This could be extended until 30s in case of disturbed lines.

•• P06.01 - P06.02 - P06.03 – The first two parameters define the minimum voltage threshold and the related hysteresis
upon restore. P06.02 cannot be set to a lower value than P6.01. P6.03 defines the intervention delay of this protection.
•• P06.04 - P06.05 - P06.06 – The first two parameters define the maximum voltage threshold and the related hysteresis
upon restore. P06.05 cannot be set to a value exceeding P06.04. Setting P06.04 to OFF will disable the maximum voltage control. P06.06 defines the maximum voltage intervention delay.
•• P06.07 – Delay for S.Q1 (Line 1) restores to the limit range, used when the line 2 (S.Q2) source is not available. Generally
shorter than P06.08, as there is the urgent need to supply power because the load is not energized.
•• P06.08 – Delay for S.Q1 (Line 1) restores to the limit range, used when the load can be connected to S.Q2 (line 2). Generally longer than P06.07, as the load is energized and consequently it is possible to wait longer before considering
voltage steadily restored.
•• P06.09 - P06.10 – Voltage threshold below which a phase loss intervention occurs, generally quicker than the drop.
The delay for the phase loss is specified by P06.10. This parameter has to be evaluate in function of load (example: damaging of engines in case of phase missing).
•• P06.11 - P06.12 – P06.11 defines the maximum threshold for unbalance between phases, referred to voltage rating,
and P06.12 defines the related intervention delay. This control may be disabled by setting P06.11 to OFF.
•• P06.13 – Max. frequency intervention threshold (it can be disabled).
•• P06.14 – Max. frequency intervention delay.
•• P06.15 – Min. frequency intervention threshold (it can be disabled).
•• P06.16 – Min. frequency intervention delay
•• P06.17 – Parameters and described characteristics are referred to ATS in AUT mode.
OFF = S.Q1 (line 1) voltage control in OFF mode disabled.
ON = Voltage control in OFF mode enabled.
OFF+GBL = Voltage control in OFF mode disabled, but the relay programmed with the global alarm function activates
or not depending on whether the voltage is respectively absent or present.
ON+GBL = Voltage control in OFF mode enabled, and the relay programmed with the global alarm function activates
or not depending on whether the voltage is respectively absent or present.

ON = Voltage control in OFF mode enabled.
OFF+GBL = Voltage control in OFF mode disabled, but the relay programmed with the global alarm function activates
or not depending on whether the voltage is respectively absent or present.
ON+GBL = Voltage control in OFF mode enabled, and the relay programmed with the global alarm function activates
or not depending on whether the voltage is respectively absent or present.
•• P06.19 – Engine start delay when S.Q1 (line 1) fails to meet set limits. If set to OFF, the starting cycle starts when the
mains contactor opens.
•• P06.20 – Max. duration of the cooling cycle. Example: time between load disconnection from the generator and when
the engine actually stops.

he ATS has the possibility to manage and generate different types of user alarms (User Alarms, Uax) and for each one can
be associated different properties:
•• Alarm enabled – General enabling of the alarm. If the alarm isn’t enabled, it’s like if it doesn’t exist.
•• Only AUT – The alarm can be generated only when automatic transfer switch is in AUT operating mode.
•• Retained alarm – It remains in the memory even if the cause of the alarm has been eliminated.
•• Global alarm – It activates the output assigned to this function.
•• Q1 Locked– When the alarm is active, no commands are sent to Q1.
•• Q2 Locked – Like previous property, referred to Q2.
•• Siren – It activates the output assigned to this function, as configured in the alarm table.
•• Inhibition – The alarm can be temporarily disabled by activating an input that can be programmed with the Inhibit
alarms function.
•• No LCD – The alarm is normally managed, but not shown on the display. This property is associated only if the alarm is
not retenitive.

(CTR). It generates an alarm for Q2 intervention.
Transfer to secondary line (remote start on-load)
When closed, it causes changeover to secondary line even
if main line voltage is within limits.
It could be used to change priority between S.Q1 and
S.Q2. The secondary line circuit breaker remains activated
until this line remains within limits.
It can be used for EJP function.
Inhibit Return to main line S.Q1
In AUT mode, when closed, it inhibits the return to main
line after it has reverted to the limit range.
It is used to prevent the second power cut out due to retransfer from occurring automatically at an unforeseeable
time.
Start Generator
In AUT mode, when closed, it causes the generator to start
after the delay specified by P05.14. It can be used for EJP
function
Emergency
NC contact which, if open, it causes both circuit Q1 and Q2
open and it generates alarm A09.
Generator ready S.Q1
When closed it signals that the generator connected to
line 1 is available for use. If this signal is missing, alarm A12
is generated
Generator ready S.Q2
When closed it signals that the generator connected to
line 2 is available for use. If this signal is missing, alarm A13
is generated
