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.

POWER SUPPLY

ATyS C20/C30 integrates 2 power inputs (104-106, 203-

205), and consider the available source to keep the
product operational. Product supplied when voltage on
terminals ≥ 100 Vac
For the DC version, these is only one power supply input
(DC-, DC+).

Priority network selection.
Network 1 has priority when input is not activated. Network 2 has priority if input is active

Mtf Remote manuel re-transfer. Feature identical to manual retransfer on keypad.

Re-transfer from priority network to backup network is allowed from input activation (1 s front).
The Mtf variable in the setup menu must be selected (Yes) to allow input recognition

(inhibited when S2A is selected)

Man Information transfer system in manual mode

All automatic commands (+ test on load) are inhibited as soon as the input is activated

CtS Remote transfer control. Possible to initiate transfer from priority source to backup source

before DTT ends. If DTT is set to its maximum value (60s), the transfer is initiated as soon as
the input is activated (1 s front)

tol Remote test on load. Started from input activation.

Re-transfer is blocked until input de-activation

TEST OFF LOAD (ACCESSIBLE IN AUT/ MODES)

It can be activated from:

• operation mode

• ATyS D20 interface

• programming input (TFL) if selected.
This test is made for applications where emergency
source is typically a genset (priority source must be
source ). This test can be activated, in automatic
mode, changeover switch in position , source
available.

Description

• This mode will start and stop remotely genset operation

Description:

• This test simulates a loss of priority source situation.
The sequence generates load transfer from priority
source to emergency source after backup source start
up operation (in case of genset). The return sequence
always keeps manual re transfer feature activated (from
priority source availability). All timers are counted down.

>

Keypad activation

After operation mode access, press mode push button
to make test on load led blinking and validate to start a

The test is only possible in automatic mode, the chan­geover switch in priority source position, priority source
being available.

Remote activation via specific input

It is also possible to start a test on load remotely with

The cycle is started from contacts closure.
The re-transfer is initiated from contacts opening.

• When priority source comes back, it can be required
not to automatically retransfer and wait for a more

TROUBLESHOOTING GUIDE

ATyS C20/C30

STATE ACTION

Electrical operation is not operational • Verify voltage applied on terminals 100 Vac to 440 Vac or 9 Vdc to 30 Vdc

for DC version

• Verify state MAN of input if selected

Product is faulty (fault is active) • Disconnect power supply to try to reset the fault
FT1, FT2, FT3, FT4 • In case of programming inputs FT1 or FT2, verify if external fault is not

active (atomatic reset).

• In case of programming inputs FT3 or FT4, verify if external fault is not
active. The fault must be reset or keypad (validation push button)

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

• Verify phases sequence

The changeover switch does not transfer • Verify state MAN of input, 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 (4000)

can not be activated from keypad

• Verify state MAN of input, if selected

The changeover switch • Verify MRT is counted down
does not re-transfer after main's return • Verify state MAN of input if selected

• Verify manual retransfer feature is not active
(press validation to allow retransfer)

Retransfer has been realised but • Verfiy CDT is counted down
emergency source in still running (did not stop) • Verify Start Gen output relay command,

terminals 13-14 (disconnect connector if required)

Electrical operation not according to commands • Verify control logic (impulse, breaker or contactor mode)

The product is in faulty position • Verify the number of AC (auxiliary contacts) 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
