SOCOMEC - Réf. : 532 929 B
The ATyS family proposes a complete motorised
changeover range including electrical and mechanical
interlocking. Manual operation is always possible on all
the products in case of emergency.
The electric command is realised via a motorised
module, electronically driven by 2 types of logic:
• Remote controlled: ATyS 3 products are controlled by
volt free contacts allowing the switch to be driven in 1,
0 or 2 position. These contacts can come from an
external control logic.
• Automatic control: AtyS 6 products integrate all
controls, timers and relays required to realise a
Normal/ Emergency application.
ATyS 6e and 6m versions also integrate the remote
controlled feature.
The motorised and control modules can easily be
replaced without disconnecting the power cables.

• An alarm is typically a warning information: fuel tank will
be empty very soon -> the genset will be stopped.
• During the functionning of one supply (G1 for example),
if an alarm AL1 appears, the second supply (G2 in that
case) is started at the end of GFt1 timer. G1 genset
is then stopped after Cdt1 timer. The emergency
genset G2 will then be maintained as long as the alarm
AL1 will be present. After AL1 disappearance, the basic
cycle will take over.

• A fault can cause an important damage -> the genset
must be stopped immediately.
• During one supply operation (G1 for example), if Ft1
appears, the second supply (G2 in that case) is imme-
diately started. The initial G1 genset is then stopped
immediately after the transfer. The emergency genset
G2 will then be maintained as long as Ft1 will be
present. After Ft1 disappearance, the basic cycle will
take over.

ACTIVE SOURCES
>
Description
When a basic cycle is started, the first started group is the
one who has the least worked, or the one who is defined
in the menu “source” (in programming mode).
Nevertheless, in a punctual way it is possible to force
this choice of starting up of the next group by “operation” menu
>
Activation
- If the LCD indicate “SAct 1”, then the next “Source
Active”, or the next source which will be started, will be
the source 1.
- If the LCD indicate “SAct 2”, then the next “Source
Active”, or the next source which will be started, will be
the source 2.
RESET OF COUNTER
>
Description
During a basic cycle, each group works during a time
defined in the “source” menu in the programming mode.
This timer can be reset punctually during a running of
the associated genset.
>
Activation
- If the LCD indicate “rES nO”, then the timer is not
reseted.
- If the LCD indicate “rES YES”, then the timer is reseted.

Operation principle
C40 controler automatically starts and stops 2 gensets
if SSt input is activated (refer to programming).
Each genset has its own operational timer.
• tF1: partial operational timer (on one cycle, refer to
programming)
• tG1: global operational timer (from last counter reset).
>
Start sequence
From SSt start signal:
• If operational time on source 1 is greater than operational time on source 2,
-> Start source 1
• If operational time on source 2 is greater than operational time on source 1,
-> Start source 2
• If next source to start has been selected on HMI,
-> Start the required source.
Rq: In case of “non starting” of priority source, after
1 minute the second source is automatically started.
>
During the sequence
• If partial timer is counted down and sst stil active,
-> The second source is started and the load transferred
• If active source disappears before the end of the
sequence,
-> The second source is started and remains active
until the end of the partial timer (refer to diagrams 2
& 3)
>
Stop sequence
The cycle is stopped
• either when the state of the input (SSt) changes
• or when a fault appears
• or when the “manual” mode is activated.

STATE ACT IO N
Electrical operation is not working • Verify voltage applied on terminals 9 Vdc to 30 Vdc for DC version
• Verify state of input MAN if selected
Product is faulty (fault is active) • Disconnect power supply and reconnect to reset fault
FT1, AL1, FT2, AL2 • In case of programming inputs FT1 or FT2, verify if external fault is not
active. If the external fault disappear it acquit the fault
• Verify inputs (NO, NC…) configuration
Source available led is never active • Press test lamp to verify led is operational (push 5 seconds)
when available • Verify nominal preset values (voltage and frequency)
• Verify voltage and frequency thresholds
The changeover switch does not transfer • Verify state of input MAN, if selected
after loss of main • Verify emergency source is available (ex: genset is started)
• Verify voltage applied on terminals
Test on load and off load
• Verify password to access test (5000)
can not be activated from keypad
• Verify state of input MAN, if selected
The changeover switch • Verify if dtt is counted down
does not re-transfer after main's return • Verify state of input MAN if selected
• Verify manual retransfer feature is not active
(press validation to allow retransfer)
Retransfer has been realised but • Verify if CDT is counted down
emergency source in still running (did not stop) • Verify Start Gen output relay command,
(contacts 13-14 or 53-54 depending on genset)
Electrical operation not according to commands • Verify control logic (impulse or contactor mode)
• Verify Rn variable in Setup menu
The product is in faulty position • Verify the number of AC in the setup menu. It must be in conformity with the
number of AC connected
• Verify the switch position
Error LCD Err XXXX • Send the product back to the manufacturer
