If the UPS is transferred to by pass mode by pushing “0” button, in case by-pass input voltage is
out of the limits, UPS passes to shutdown mode or switch off, depending on mains voltage. It is
suggested to use green mode if you don’t want any interruption.
If the by-pass input voltage gets out of limits after the “0” button is pressed during on-line operation, UPS
shall switch into Shutdown Mode.
If UPS passes to by-pass mode because of overload conditions, and by-pass input voltage gets out of the
limits, it is dependent on the amount of load for the ups to return to online operation.
5.1.1.3
Battery Mode (BATTR)
In this mode of operation, UPS converts the battery voltage to a suitable DC voltage, which can be
converted to a voltage value equal to mains voltage of the inverter. UPS is at the same time on by-pass
mode. This is an exceptional case that UPS is on two modes at the same time.
During on-line mode, and mains input is out of the limits, UPS passes to battery mode. (If there are
no other abnormal conditions). Necessary energy to operate the inverter is supplied by the battery.
During green mode, both mains input and by-pass input are out of the limits, UPS passes to battery
mode. Necessary energy to operate the inverter is supplied by the batteries.
During green mode, mains input only is out of the limits, inverter is supplied from battery, but load is
supplied from the by-pass line.
You may switch on the UPS by pushing “CS” button, even if mains input is lower than 130 V or input
fuse is on “0” position. In this case UPS switch on shutdown mode, and make self test. If everything is ok,
UPS operate on battery mode.
Autonomy time depends on battery type, quantity, and load level. UPS stops feeding the loads if the
battery voltage falls under a certain value. Battery life decreases if battery capacity falls below a certain
level. Therefore, UPS stops operating in battery mode when the battery capacity falls below 30% of its
total capacity.
5.1.1.4
Shutdown (SHUTD)
During the shutdown mode, even the UPS is switched on, there is no energy on the output and load is not
supplied.
UPS makes self-test during the start up to check if everything is normal. During this operation, UPS is on
shutdown mode.
Other shutdown mode conditions;
User push the “0” button when the by-pass input is out of the limits,
UPS switches into shutdown mode if by-pass input voltage gets beyond limits, while mains voltage is
within limits and UPS is disabled,
User push the “0” button, and send shut down command through communication interface.
In addition,
During the battery mode, if shut down command is sent through the communication interface, and if
the mains comes back to normal conditions, for a short period UPS passes to shutdown mode, and
then passes to normal ( mode chosen by the user, on line, green or by pass mode) operating mode.
During the on-line or green mode operation, if shut down command is sent through communication
interface, for a short period, UPS passes to shutdown mode, and then passes to normal ( mode
chosen by the user, on line, green or by pass mode) operating mode.
