3. Operation
3.3 Normal mode. Operation on preferred source S1
Operation on the preferred source
Automatic transfer to the alternate source
Manual transfer to the alternate source
During normal operation on the preferred
source S1, LEDs 24 , 29 , 30 , 31 , 32 ,
33 , 36 and 38 are on in green.
The load is automatically transferred to the
source offering the highest level of power
quality.
For example, if the preferred source S1
goes outside tolerances, LED 31 goes
orange or red. The buzzer beeps.
Upsilon STS automatically transfers the
load to the alternate source S2. LEDs 24 ,
29 , 30 , 32 , 34 , 36 and 38 are on.
Upsilon STS transfers the load
back to the preferred source S1 as
soon as it returns to within
tolerances.
To stop the buzzer, press the
function button marked .

1 - Press the manual transfer button 25 :
2 - Confirm the order by pressing the grey
function button 23 marked on the
screen.
LEDs 24 and 27 flash.
After the transfer, the green LED 27 goes
on.
The load is supplied by alternate Source 2.
Transfer is authorised only if the
two sources are within tolerances
(voltage, frequency) and their
phase displacement is within the
set limits. If these two conditions
are not met, the transfer order is
stored in memory and executed
when the voltages cross zero.
If transfer does not take place
within thirty minutes, the order is
cancelled.
