TEBEVERT III INVERTER SYSTEM (120 VDC)
07.11.2011 41 028-0009-006
The AC by-pass is connected to the output and the DVA shows the AC by-
pass voltage (e.g. 120), if the selector switch underneath the DVA is in the
position "V".
The first inverter can now be switched on. After a start-up time of approx.
20 seconds, the LEDs "INVERTER OUTPUT VOLTAGE PRESENT"; "MAINS
SYNCHRONOUS" are lit up and the LED "PARALLEL OPERATION" starts to
flash. The flashing of this LED indicates that this inverter has been
assigned the MASTER function. At the same time, some of the LEDs on
the SBS change their state. The LED "FAULT" is extinguished and the LED
"READY FOR OPERATION" is lit. Assuming that the operation mode is
"inverter priority", the inverter output voltage is connected to the output.
The LEDs "INVERTER OUTPUT VOLTAGE PRESENT" and "INVERTER
OPERATION" light up and the LED "MAINS OPERATION" are extinguished.
The voltage-free fault indicator switches to the state "no fault".
The remaining inverters are then switched on. The state of the LEDs of
the SBS and the first inverter do not change. After the start-up phase, the
LEDs "INVERTER OUTPUT VOLTAGE PRESENT", "MAINS SYNCHRONIZED"
and "PARALLEL OPERATION" are lit on the additional inverters.
Finally, the load circuits may be switched on. When the load is connected,
the load current is divided equally between the individual inverters and the
bar graph indicators show the output current of the individual inverter.
The load voltage (inverter output voltage) or the total load current can be
read off the DVA.
After all the system components have been connected or switched on as
described, the states of the LEDs on the SBS and the inverter should be as
follows.
