transfer from manaul bypass operation to online operation
•
If the UPS is switched off , then bring the battery, battery charger, output, bypass and input fuses
to “1” position RESPECTIVELY.
•
Please check and control that UPS is switched on.
•
After a period of switching the UPS on, “MB” message on the front display panel should be
observed and bypass LED should be litting.
•
Bring the manual bypass switch to “0” position.
•
Please wait for 10seconds.
•
On the front display panel, if there is mains then “ONLINE OK” , if there is no mains then “
BATTR. OK” messages should appear.
•
If you observe “ BATTR. OK” message the please recheck again if the mains is present, and if
the input fuses on the distribution panel and the input fuse on the UPS is at “1” position.
5.1.3 Operating Features and Values
5.1.3.1 Online Mode and Voltage Tolerance
Voltage tolerance sub-limit for on-line operation depends on the load level.
Load and voltage relation is given for the sub-limit in the chapter 9.
Voltage tolerance for upper limit does not depend on the load and is 280V. If the voltage is over 280V,
UPS passes to battery mode. To come back to on-line mode, it is necessary that the voltage should go
down to 275V.
5.1.3.2 By-pass Mode Voltage Tolerance
Factory configuration for by-pass mode voltage tolerance is between 198 V – 242 V (
±
10% of the
nominal input voltage). You may ask to change this limit, please contact to authorized Inform partner. If
the voltage is out of the above limits, UPS does not work on by-pass mode.
To come back on by-pass mode, by-pass voltage has to be within between 203 V- 237 V (following the
factory settings) (+5V lower limit) and (-5V upper limit).
5.1.3.3 Battery Management and Autonomy Time
UPS has smart battery management system. To be able to charge the batteries, UPS has to be on on-line
mode, and mains input within the operating limits. Thanks to algorithms used, smart battery management
increases the lifetime of the batteries. These advantages are as follows;
Charge the batteries even the mains input goes down to 80V,
Load independent battery charging current,
Temperature controlled battery charging,
Battery current and voltage are shown in the figure below;
