ATYSp - 542001E - SOCOMEC
The fault LED is on (ATS
Controller)
• 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 congurable
inputs, the fault LED on the ATS controller will be on. This is a normal condition and resettable
by opening the associated contact input.
The SOURCE availability
indicator does not
illuminate when the source
is available.
• 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 conguration
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.
The product displays the
message:
F13 ROT-1 or F23 ROT-2
• Check for phase rotation consistency (or conventional direction) between
the source and parameter ROT in the SETUP menu, or between the two
sources.
Nothing happens following
a loss of the priority source
(application Main-Gen)
• 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.
The product does not
switch over after the priority
source is lost.
• 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.
Return to priority source
1 has been executed, but
source 2 is still running
(M-G application)
• 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.
The ON LOAD and OFF
LOAD tests cannot be
started via the keypad
• 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).
Product displays an event
or error message
• Refer to chapter Events list and Error messages list in this manual.
