UPS out of Function Operation
transfer from online operation to manual bypass
Please proceed as described below in order to transfer the load from online operation to manual bypass
operation without interruption. The below instructions should be followed up respectively for user safety
and preventing the load to be disenergized .
•
please check that UPS is at online operation mode ( On the front display panel of the ups, “
ONLINE OK” message should be observed. )
•
Pressing the “ I “ button on the front panel of the ups for necessary times, provide the transfer to
GREEN MODE . ( On the right upper line of the display panel, “G” letter should be observed. )
•
On the front display panel “ BYPASS OK” message should be observed and the bypass LED
should lit.
•
Bring the Manual Bypass Switch to “1” position.
•
Please check and observe the “MB” message on the lower line of the front display panel.
•
Bring the output, bypass, battery charger and battery fuses to “0” position .
•
Please check and control that the UPS is switched off completely.
Now the connected loads are supplied through the manual bypass switch of the ups from bypass line. In
case of a energy cut off during this operation mode, your connected
loads shall remain without energy.
CAUTION:
Although the fuses of the UPS is at “0” position and the UPS is switched off, if the manual bypass
switch is at “1” position than there is still bypass voltage on the output Clemens of the ups and on the
supply part of the loads. Do not operate on these points ( output Clemens and load supply parts)
before taking the manual bypass switch to “0” position.
Check the user manual in case of non-described conditions in this instruction sheet.
Exceptional Cases
If you can not transfer your UPS to static bypass by pressing “I” button before passing to manual bypass
and observe “ ONLINE OK G” message on the front panel, this is an indication of the unavailibility of
the bypass voltage for transfer. This means that the bypass voltage and/or frequency is out of allowed
limits. Please check and control that you have the bypass connection and bypass fuse is in “1” position.
until you observe “G” message on the front panel, please pres continously to “I” button. If you bring the
manual bypass switch in “1” position although you have not received the “BYPASS OK” message on the
front panel, then you energise the loads with an inconvenient voltage and/or frequency. During this
transfer even your loads may remain without energy for a while. If you observe “BATTR. OK” message
on the front panel, then this means that the ups is operating from the mains due to the lack of input
mains. If the input fuse is not in “0” position and there is bypass voltage, then by pressing “I” button
from the front panel, you can obtain the transfer to green mode operation. If you observe “BYPASS OK”
message on the front panel, then by bringing the manual bypass switch to “1” position, you can provide
the uninterruptible transfer to manual bypass line.
