1P +N:
The C35 is suitable for single phase networks, for with voltages within 184-300 V.a.c Ph-N. In these networks, the phase must
be connected to the L1 input (terminal 104 for source 1 and 204 for source 2).
2P:
When monitoring a 2PH network without neutral 90-520 VAC PH-PH, connect the two phases to L1 & L2, the controller must be
supplied with 184-300 VAC between the L1 and N connector (in order to achieve this users can use a transformer connected to
the two phases to create this voltage and connect the secondary to the neutral connector).
3P:
The C35 is suitable for three phase without neutral networks, for with voltages within 318-520 PH-PH. In these networks, the
controller must be supplied by 184-300 V.a.c using L1 and N (this can be achieved by using a transformer between L1 and
another phase and connecting the secondary to the neutral input 103 & 203).
3P+N:
The C35 is suitable for three phase with neutral networks, for with voltages within 184-300 V.a.c Ph-N and 318-
520 PH-PH. In these networks, the phase must be connected to the L1 input (terminal 104 for source 1 and 204 for source 2).

CAUTION ! In 3 phase networks with neutral; in balanced networks; there is a risk that loss of neutral will not be
detected. To limit this risk the reduce the source 1 and source 2 overvoltage and undervoltage thresholds.
(Cf chapter "12. Programming", page 27).
CAUTION ! When using 3P network without neutral, the controller must be powered using 184-300 VAC between
L1 and N. User may use a transformer between two phases to create this voltage.

10
11
12
1 8
2 3 4 5 6 7

The 4 working modes are working as described below:

• Auto mode
In this mode the controller will automatically give orders to the RTSE connected to switch to the correct position according to the
settings selected.
In this mode, the manual order buttons , , are disabled.
This mode is activated when the RUN LED is on (9). To access this Mode make sure that you are in manual mode (the AUTO
LED (1) is OFF and that the fault LED (11) or the TEST/PROG LED (1) are not activated),
Then, press the button the screen will then prompt users to enter the password (configurable default is 1000).
After the correct password has been entered, the AUTO LED (1) should then turn ON:

• Manual mode
In this mode the manual orders buttons , , enable manual orders to switch respectively to position I , 0 or II.
This mode is activated when the AUTO LED (1) is OFF, the Fault LED (12) is OFF and the screen does not indicate “NOT IN
AUTO” or “Inhibit” or the TEST LED (8) are not activated. To switch from AUTO mode to manual mode, press the button the
screen will then prompt users to enter the password (configurable default is 1000).
After the correct password has been entered, the AUTO LED (1) should then turn OFF.
• Inhibit mode
In this mode both the Automatic transfer and manual orders will be blocked. This mode is activated when the programmable
inputs are programmed to “NOT IN AUTO” or “INHIBIT”.
In this mode the fault LED (12) will be blinking, and AUTO LED will be OFF and the screen will show “NOT IN AUTO” or
“INHIBIT”. To leave the inhibit mode close the input, the controller will return to previous working mode. Message on the screen
should clear automatically after input has been deactivated.
• Programming mode
This mode allows product parameter configuration.
To access this mode , long press (>3s) on the button, the screen will prompt to enter the password (Configurable, default
1000), while in the programming mode the LED 8 will be ON. To exit this mode press the (return button) until the LED 8 is OFF,
the controller will then return to the previous working mode (Auto or Manual).

11. CONNECTIONS
11.1. Triple power supply

The ATyS C35 can be supplied by 3 power sources:
AC – Power through the voltage sensing (terminals 103-104 for source 1 and terminal 203-204 for source 2) with power supply
range going from 184-300 V.a.c (in pulse mode) 200-300 V.a.c (with CC TYPE technology) 50/60 Hz+/- 10%
DC - Auxiliary supply (not mandatory to use), 10-30 V.d.c power supply using terminals 82-81. This DC power source can be
used to keep the controller on in order to have timers, communication, screen and genset output active even if source 1 and
source 2 are not available.
If the DC power source is the only power source available the screen back-light time will be reduced and the external DPS will
not be active.
When using CC TYPE RTSE it is recommended to not use the DC auxiliary supply as contactors will open during loss of Source
1 and Source 2 voltage and this will create a "POS1 ERROR" or "POS2 ERROR" fault on the controller.
CAUTION ! The EXTERNAL AC DPS output to the RTSE will not be functional when powering through the DC
auxiliary power supply only.
11.2. Voltage sensing inputs

The ATyS C35 includes dual single phase and 3 phase voltage sensing (terminals 103-106 and 203-206) designed to monitor 1
Phase supplies up to 300 V.a.c (L-N) and 3 phase +N up to 520 V.a.c (L-L).
The ATyS is designed to handle single phase and three phases with neutral networks, simply define the correct configuration of
the network using the programming mode (cf. chapter 12 - Programming).
Sensing values measured will have a direct influence on determining the availability of the main and alternate supplies as well as
the ATyS C35 automation.
The parameters monitored through the sensing are the following:

• Phase rotation
Phase rotation order can be selected in the programming mode “System”  “ROT PH.” It can be set to L1L2L3, L1L3L2 or
OFF (default value is OFF).
• Frequency within set limits

The ATyS C35 will check that the frequency is within the limits configured through the programming mode “Frequency” menu.
• Loss of the main or alternate power supply

Loss of supply depends on the nominal voltage and frequency configured together with the hysteresis in the programming
mode “Voltage”, the sources will be considered as lost if the source is outside the set thresholds for the duration of the fail
timers. The fail timers can be configured in the programming mode “TIMER”.
• Return of main and/ or alternate power supply

Return of supply depends on the nominal voltage and frequency configured together with the hysteresis set in the “Voltage”
menu. The source will be considered as available if the source voltage remains within the set hysteresis threshold for the
duration of the return timer. The return timer can be configured in the “TIMER” menu.
• Loss of Neutral
In a 3phase network with unbalanced loads the loss of the neutral will be detected.
WARNING ! If the Neutral is lost in a balanced network, loss of source could be undetected, to minimize this reduce
the threshold on voltage sensing.

11.3. Outputs
11.3.1. Control signal outputs

Control signal outputs are the output orders (dry contact) to the RTSE, these outputs are rated for 250 V.a.c 50/60 Hz 5A
general use and 30 V.a.c 5A general use.
The control signal outputs logic will vary depending on the technology set in the menu “System”  “TECHNO TYPE”
Techno type Order(1) Contact 17-16 Contact 17-15 Contact 17-14 Contact 17-13
Position 0 Closed Open Open NC
PC / CC Position I Open Closed Open NC
Position II Open Open Closed NC
Position 0 Open Closed Open Closed
CB Position I Closed Open Open Closed
Position II Open Closed Closed Open
(1) Orders can be given through the automatic logic of the controller in automatic mode or using the pushbuttons in manual mode
The duration of the order can be changed in the programming mode in “System”  “SIGNALTIME”, the duration can be
changed from 0.1s up to 20s or changed to be maintained by going above the 20s value (default value is 5s).
From 0.1s-20s, orders are sent for duration set in "SIGNALTIME". If the RTSE does not reach the requested position in the set
time a FAULT for the corresponding position.
In CC Type technology when an order is sent it will be maintained until a different order is sent.
11.3.2. Genset start output
Genset start outputs are the output orders (dry contact), the contact between 51 and 54 will open & the
contact between 51 and 52 will close when the signal to start the genset should be sent (during a test on load
or when source 1 is lost). These outputs are rated for 250 V.a.c , 50/60 Hz 5A general use for NO contact and
3A general use for NC contact, and 30 V.d.c 5A general use for the contact between 51-54 and 3A general
use for the contact 51-52.
Control 51/54 51/52

Generator Start Contact open Contact closed
Generator Stop Contact closed Contact open
When the switch returns in position I the Cooldown timer will start counting (Default value 180s) during the cooldown timer, the
contacts will maintain the generator start signals.
CAUTION ! If the 24 V.d.c auxiliary power supply is not used the timer 1FT will not count and the order to start the
generator will be sent immediately when source 1 is completely lost.
In Main-Main mode: if “S1-Mains S2-Mains” is selected in “System”  “APP” the start-gen output can be configured for other
functions in the menu I/O. see chapter "12. Programming", page 27 for possible output functions.

11.4. Inputs
11.4.1. Programmable Inhibit input
The inputs 91-94 can be set in the programming menu “I/0”, by default output 1 (contact 91-92) is set to
“NOT IN AUTO”. See chapter 10.5.2 Programing for more details on the input functions.
11.4.2. Position inputs
These inputs must be connected from the RTSE to the controller in order to indicate the position of the
RTSE, when the controller gives an order both through manual command and automatically it will check
that the position input corresponding to this order has closed. If this is not the case the controller fault LED
will blink and the buzzer will be on, to clear the fault expected position input should be closed and the user
must press the AUTO button.
In PC mode:
73/70 must be closed when the RTSE is in position 0.
72/70 must be closed when the RTSE is in position II.
71/70 must be closed when the RTSE is in position I.
In CB techno only inputs I (for breaker 1 closed) and II (for breaker 2 closed) are mandatory. To connect the 0 input both breaker
open contacts can be placed in series and inserted in the O output, however this is not mandatory.
In CC techno the input outputs are the same as in PC techno but the position O feedback (73/70) is optional.
11.4.3. Fire input
This input is activated by applying 24 V.d.c (12-24 V.d.c) on F1 and F2 (negative electrode connected to F1 and
positive electrode on F2.
When this input is activated, the Fire LED (13) will be ON (fixed) and the buzzer will sound, the controller will give
the order to the switch to go to position 0 and both manual and automatic controls will be inhibited. When the
input is removed, the switch will go back to the last working mode automatically.
11.4.4. RS485
The RS485 connector provides the Modbus communication allowing to read values from the controller
(eg: Voltage values, settings, switch position etc...) for details on the values that can be read through
communication (see Annex II).

12. PROGRAMMING
12.1. Access to programming mode

To access the programming mode, long press (>3s) on the button, the screen will prompt to enter the password
(Configurable, default 1000),
In programming mode use the button to go down the menus, the button to go up, to validate/enter and
to return.
While in the programming mode, the LED 8 will be ON. To exit this mode press the (return button) until the LED 8 is OFF,
the controller will then return to the previous working mode (Auto or Manual).
To save parameters validate using the leave the programing mode using button and select “YES” when prompted to
save the settings, the controller will beep twice to indicate that parameters have been saved.
WARNING ! When in programming mode the controller will not be in automatic.
DANGER ! When leaving automatic mode, if previous mode was automatic the RTSE might transfer directly.
Therefore it is recommended to place the C35 in manual mode before programming.

ATyS S
ATyS S products are 4 pole re motely operated transfer switches with positive
break indication. They enable the on-load transfer of two three-phase supplies
via remote volt-free contacts, from either an external automatic controller, using
pulse logic, or a switch. They are intended for use in low voltage power supply
systems where a brief interruption of the load supply is acceptable during
transfer.

Annex I - 4. Phase rotation check
The controller will check that each of the source present match the phase rotation order programmed in “SYSTEM” “ROT
PH”. Possible settings are L1L2L3, L1L3L2, or OFF, if the setting is set to OFF the controller will not check the phase rotation of
sources. If the phase rotation of the source does not match the settings the source LED in question will blink (LED 2 or 7), the
fault LED will be on (fixed) and the controller will not switch over to this source even if this is the priority source or the only source
available.

information: Phase rotation order is active only for 3P+N networks, in all other networks phase order will not be checked
to determine source availability
Annex I - 5. Voltage/Frequency Levels configuration

Voltage and frequency levels can be configured through the screen or with RS485 communication using the write function.
Nominal voltage and nominal frequency is configured in “SYSTEM””NOM. VOLT.” And “SYSTEM””NOM.FREQ”, hysteresis
and threshold values are configured in “Voltage” and “Frequency”
Source 1 and source 2 nominal voltage and frequency is common, but hysteresis and threshold values can be changed
independently for each source.
When the source value goes beyond the threshold for the duration of the “Fail timer” FT the source is considered unavailable, to
be considered available again the source value must be below the hysteresis settings for the duration of the “return timer” RT.

Settings configured can be seen in the navigation screens 2 and 3:

Annex I - 6. Timers
All timers can be configured in programming mode in the menu “Timers”.
Annexe I - 6.1. Fail timers and Return timers

The source fail timer FT is the time during which the source can be outside the voltage and frequency threshold before it is
considered lost. (cf. graph in previous chapter)
The source return timer RT is the time for which the source must be within the voltage and frequency threshold before it is
considered available. (cf. graph in previous chapter)
If only one source is present, the controller will give the order to switch to this source before the return timer has finished
counting.
Annexe I - 6.2. Cooldown and start gen delay timers

When the switch returns in position I the Cooldown timer will start counting (Default value 3min /180s) during the cooldown timer,
the contacts will maintain the generator start signals and release the signal when the timer is over.
The genset delay timer (SD), allows user to delay the start of the genset after a loss of the Mains.
Annexe I - 6.3. Dead band timer ODT

The dead band timer S1->S2 ODT S2->S1 ODT This timer defines the time for which the switch should stay in the 0 position
when transferring from one source to another.
Annexe I - 6.4. All timers’ chronograms

This chronogram is for installations using the 24 V.d.c auxiliary supply on at all times, source 1 set as a priority source and
retransfers set to automatic.
If the auxiliary supply is not present and no sources are available the fail timers will automatically be set to zero, and the start-gen
contact will be active immediately after loss of supply (51-52 closed).

Annex I - 7. Priority settings & Retransfer
Priority settings to S1 or S1 can be configured in the programming mode in “System””PRIO NET” depending on the setting in
“System””RETURNS” the controller will transfer back to the priority source.
If “AUTO RETRANS” is selected the controller will automatically retransfer to the priority source once it becomes available (Return
time for this source completed).
If “MANUAL RETRANS” is selected the controller will wait for validation on the HMI before retransferring to the main source, the
screen will show the following message when waiting for user validation:
To validate press the button.
Annex I - 8. Tests
The C35 allows for two configuration on the test button, “TEST ON LOAD” or “TEST OFF LOAD”, to change the configuration go
in programming mode “Test”  “BUTTON TEST”.
To start a test do a long press (>3s) on the button test when in manual or automatic mode the controller will request the
user password before starting the test, once the test starts the test LED will turn on. The test will stop when the user presses the
test button again for at least 3 seconds, the controller will return to the last working mode.
In Main-Main mode the genset start output will not be activated.
Sequence for TEST ON LOAD:
Allows user to test the full genset + ATS function

Sequence for TEST OFF LOAD:
Allows users to test the genset function without transfer, in Main-Main mode this test will not be functional.

ODBUS COMMUNICATION ADDRESS AND DESIGNATION
DETAILS
The communication protocol adopts the standard MODBUS-RTU protocol, with master-slave acknowledgment connection (half duplex).
As standard the baud rate is set to 38400, parity bit to 1 and slave address to 03 (these settings can be modified through
Modbus or using the HMI in "MENU">"System">"COM"). When the product is communicating the COM Led will blink.
The following tables describe the Modbus addresses, and data format for the C35. Some addresses are RO (read only) and can
be accessed using the modbus read function 0x03/0x04, some data are read and write (RW) and can be accessed using the
functions (0x03/0x04 to read 0x06/0x10 to write) :
