Status leds
LEDs displaying the status of the QC-RPS-160-SN0 main power supply
are found on the upper left section of the unit. See the figure.
Meaning
FAULT BLINKING. Red LED blinking. It indicates that there is no error
at the power supply and that there is no mains voltage. The system is
ready waiting for mains power to be connected. State 0 of the operating
modes.
FAULT ON. Red LED on, not blinking
. It indicates that there is an error
either at the power supply or in some module of the QC-PDS system.
The error will be shown on the electronic status display of the power
supply - see the section electronic status indicator below. It indicates
that the system is not ready · SYSTEM OK open ·. State 4 of the
operating modes.
FAULT OFF. Red LED off
. Indicates that there are no errors at power
supply and the presence of mains phases. The system is charging the
DC BUS.
REGEN ON. Amber LED on. Indicates that the power supply is
returning energy to mains at that particular moment.
DC BUS ON BLINKING. Green LED blinking. Indicates that the module
is working in RB6 mode.
DC BUS ON. Green LED on. It indicates that the DC BUS is fully
charged and the unit provides all its power at the BUS.
Electronic status indicator
The 7-segment status electronic display shows the system start-up
sequence as well as the possible errors and warnings that could arise.
Start-up sequence
After starting the QC-RPS-160-SN0 power supply, or after it has been
RESET, the 7-segment electronic display will show:
The software version, after the r with the identifying digits.
The error code list.
The phases shown on the 7-segment electronic display are:
Software version displaying stage. Displays the software version of
the power supply. It first shows the letter r (indicating the release
version), followed by the version number (digit by digit) (see
A). When
the drive is active and the axis is being governed, the electronic
display will prompt a 0 with a blinking point see
B).
NOTE. If the red LED is on, but not blinking, and the electronic
display of the power supply prompts a 0 with the point blinking, see
the section ELECTRONIC STATUS INDICATOR, the error is originating in
one of the other modules of the system and not at the QC-RPS-160-
SN0 power supply.
