ATyS Controller A15 - 549779A - SOCOMEC
15.3. Phase rotation check
When both sources are available the controller will check that both sources have the same phase rotation.
If the two sources have different phase orders the source LED (1 & 6) will blink , the fault LED will light up and the sources will be
considered as not available (switch will not transfer from the current position to the opposite source).
If only 1 source is available the product will not check the phase rotation order.
15.4. Voltage/Frequency Levels configuration
Voltage and frequency levels can be configured through communication or DIP switch (DIP switch 4).
Configuration through DIP switch
The DIP switch configuration allows setting the voltage and frequency limits to 10% of nominal vol -
tage & 5% of nominal frequency or 20% of nominal voltage & 5% of nominal frequency.
In both cases the hysteresis is 20 % of the selected value. The default value for nominal voltage is
230 V.a.c and the default value for nominal frequency is 50Hz.
To reboot the product press the button for 30s, this will restart the product and take into account any changes on the DIP
switches (even if the controller was in AUTO mode at the time of restart). In case of a configuration change the controller Buzzer
will beep twice.
15.5. Timers
15.5.1. Fail timers and Return timers
Source failure timers FT and source return timers can be configured using the DIP switches.
The source fail timer FT is the time during which the source can be outside the voltage and frequency threshold before it is
considered lost. (cf. graph below)
The source return timer is the time for which the source must be within the voltage and frequency threshold before it is considered
available. (cf. graph below)
If only one source is present, the controller will give the order to switch to this source before the return timer has finished counting.
