Operating Modes
Following the status of mains&by-pass voltage, UPS can operate either one of the below operating modes.
5.1.1.1
On-line Mode (ONLINE)
Online mode is available if the mains is within the allowed operating limits. In this mode, UPS supply the
load and charge the batteries. Load is supplied through inverter and inverter is on-line.
If;
On-line mode is chosen, the mains input is in the acceptable limits, and there are no abnormal
conditions ( such as over temperature, overload, failure ..etc),
Green mode is chosen, by pass input voltage is out of limits, but the mains input voltage is in the
acceptable limits, and there are no abnormal conditions (such as over temperature, overload, failure
..etc),
UPS operates in on-line mode.
5.1.1.2
By-pass Mode (BYPASS)
If the voltage in the by-pass input is transferred to the output by using either electronic or manual switch,
this mode is called by-pass mode. Your UPS has both electronic (static) and manual switch.
You can pass to Maintenance Bypass Mode by using the manual bypass switch on the ups. This switch is
used to transfer the bypass voltage to the output of the ups manually when the ups is not in function.
Maintenance Bypass Switch (manuel bypass) is an uninterruptible switch. In case of use, the
instructions in section 5.1.2.3 should be followed up properly in order to maintain an
uninterruptible transfer to byapss. In condition to transfer from manual bypass line to normal
operations, the instructions in 5.1.2.3 should be followed up.
On by-pass mode, by pass input voltage is transferred to output through the thyristors. Load is supplied
by by-pass input voltage. Inverter is off.
By-pass input voltage must be within the operating limits.
The unit;
•
Stays at this mode when green mode is chosen, if by pass input voltage is within the
acceptable limits,
•
On-line mode is chosen, by-pass input voltage is within the acceptable limits, if one of the
below conditions occur, UPS passes to by-pass mode. If normal conditions are obtained, then
UPS passes to on-line mode;
*Prolonged overloading,
*Over temperature,
*Failure on the UPS,
During the on-line operation, if the by-pass input voltage is within acceptable limits, or in green mode
operation, when you push to“0” button, UPS passes to by-pass mode. If the by-pass input voltage is
out of limits, UPS does not pass to battery mode, and switch off itself.
