ATySController C55/65 - 549866C - SOCOMEC
14.2.11. CYCLER
This function allows users in Main-Main (1) and Gen-Gen (2) to cycle periodically on each source.
Cycle functions are generally used to divide equally the use on the transformers or generators upstream or to change the
sources to minimize electricity costs using night/day billing.
To activate this function controller must be in Main-Main Or Gen-Gen application.
Once the function is enabled users will be able to congure the transfer validation method (automatic or transfer at a specic
time) the time of transfer (if specic time has been selected in transfer method) as well as the duration of a cycle.
In case of a loss of source during a cycle, the controller will switch to the available source and stay there until the lost source
becomes available and the cycle is over.
The backup gen-gen function allows cycling between two gensets only when the input is active, this input usually comes from
another ATS system or any other indicating that the primary source is lost (3).
To activate the backup gen-gen mode the controller must be in Gen-gen application, with an input congured to “BACKUP
GENGEN”, in backup mode the 24 V.d.c auxiliary supply is mandatory to keep the genset start signals inactive.
SETTING OPTION DESCRIPTION
STATUS ENABLED, DISABLED Option to activate or not the cycling function, application must be GEN-
GEN or MAIN-MAIN to enable
TRANSFER METHOD AUTOMATIC, SPECIFIC TIME If AUTOMATIC is slected transfer will take place as soon as the set cycle
duration is over. If specific time is selected transfer will take only at the time
configured if the cycler duration is completed.
S1 CYCLER DURATION (h) 0-9999 Duration of a cycle for source 1
S2 CYCLER DURATION (h) 0-9999 Duration of a cycle for source 2
TRANSFER TIME 00:00 - 23:59 Time of the day at which the transfer will take place (only if SPECIFIC TME
has been set in TRANSFER METHOD
BACKUP GEN GEN START MODE
PRIO SELECTION PRIORITY SOURCE, FULL
CYCLE, LEAST USED,
ALTERNATE
"This setting is only active when the BACKUP GEN-GEN input has been
programmed. It will determine which genset to start first in backup gen-gen
mode:
- PRIORITY SOURCE: genset on the source programmed as priority source
- FULL CYCLE : If cycler is ENABLED, the genset which has not completed
it's full cycle duration will start
- LEAST USED : will start the genset with the least run time
- ALTERNATE : will start the genset which was NOT the last to be active"
