The fault LED is on (ATS
Controller)
The SOURCE availability
indicator does not
illuminate when the source
is available.
The product displays the
message:
F13 ROT-1 or F23 ROT-2
Nothing happens following
a loss of the priority source
(application Main-Gen)
The product does not
switch over after the priority
source is lost.
Return to priority source
1 has been executed, but
source 2 is still running
(M-G application)
The ON LOAD and OFF
LOAD tests cannot be
started via the keypad
Product displays an event
or error message
ATYS p - 542001E - SOCOMEC
• Switch the ATyS p from AUT to Manual and back to AUT. Should the fault
condition remain contact SOCOMEC)
Note: In case the external fault / alarm condition is active through one of the ATyS configurable
inputs, the fault LED on the ATS controller will be on. This is a normal condition and resettable
by opening the associated contact input.
• Press the "LED test" button and ensure that the corresponding LED's
illuminate.
• Check in programming mode that the nominal voltage value (by default
set to 400V), the nominal frequency value and the network configuration
correspond to the network and modify if necessary.
• Check the voltage and frequency thresholds and hysteresis for this source, in
the Volt and Frequency menus and modify if necessary.
• Check for phase rotation consistency (or conventional direction) between
the source and parameter ROT in the SETUP menu, or between the two
sources.
• Check the setting of 1FT.
After 1FT has counted down 71-72-74 should change state.
• Check the status of the "gen set start" contact (contact 71-73-74) after 1FT
countdown.
• Check the wiring from the "gen set start" contact (71-72-74) to the
generating set controller.
• Check back-up source availability.
• Check back-up source voltage and frequency thresholds and hystereses and
modify if required.
• Check that the product selector switch is in AUTO.
• Check that automatic operation has not been inhibited by external orders.
• Check priority source voltage and frequency thresholds and hystereses and
modify if necessary.
• Check that the time-delay 1RT (Source 1 Return Timer) has counted down,
and that it is not too long. (The display indicates 1RT xxxSEC).
• Check in programming mode that the "manual retransfer" function is not
activated. If this function is unnecessary: In the SETUP menu, the RETRANS
variable must be at NO.
• Check that automatic operation has not been inhibited by external orders.
• Check that the INH input is not activated.
• Check that CDT (Cool Down Timer) has counted down. The display indicates
CDT xxx SEC after switchover to the priority source.
• Check the status of the "gen set start" contact (contact 71 – 72 - 74) Check
that the contact changes state after timedelay CDT has counted down.
• Check that the product is not in MAN, CONTROL or INH mode. In this case
Manual or Control LMED would be On.
• Check that the mode selector switch is set to AUT and that the AUT LED is
illuminated.
Note: In Manual mode, only the OFF LOAD TEST can run.
• Check the operating mode password (factory code 0000) to access the test
functions.
• Check that the ON LOAD TEST or OFF LOAD TEST LEDs are illuminated,
according to the selected test mode.
• Check that the product is set to application type M-G.
• Check that there is no mains loss when starting the test. The SOURCE LED
(priority side) should be illuminated.
• Check the status of the "gen set start" contact (contact 71-72-74).
• Refer to chapter Events list and Error messages list in this manual.
