Lights indicating the status of the main power supply
All the RPS regenerative regulated power supplies has the following lights
on the front panel to indicate the status of the main power supply:
 FAULT BLINKING. Blinking red LED. It indicates that the system is
ready waiting for mains to be connected. It indicates, therefore, that
there is no error and that there is no line voltage. 0 state of the operating
modes.
 FAULT ON. Red LED on all the time. It indicates that there is an error
either at the power supply or in some module of the DDS system. The
error will be shown at the display of the power supply - see the section
“status display” later on - as well as at that of the relevant drive. It
indicates that the system is not ready (
SYSTEM OK open). 4 state of the
operating modes.
 FAULT OFF. Red LED off. It indicates that the system is charging the
DC BUS. It indicates, therefore, that there is no error and that the mains
phases are on. State 1 of the operating modes.
 REGEN ON. Amber LED on. Indicates that the module is returning
energy to mains at that instant. State 3 of the operating modes.
 DC BUS BLINKING. Green LED blinking. Indicates that the module is
working in RB6 mode. State 2 of the operating modes.

DC BUS ON. Green LED on. It indicates that the DC BUS is fully charged
and the module offers all its power at the bus. States 2 and 3 of the
operating modes.
Lights indicating the status of the auxiliary power supply
RPS regenerative power supplies have a reset button and the following
lights on the front panel to indicate the status of the integrated auxiliary
power supply:
 RESET. Initializes the auxiliary 24 V DC power supply.
 OVER VOLTAGE. It indicates an error due to over voltage at the 24 V
DC output or due to over-temperature.

OVER CURRENT. It indicates an over current error at the 24 V DC
output.
 ON. It indicates that there are 24 V DC at the output when is turned on.
NOTE . If the red LED is always on and the display of the power supply
shows a 0 with a blinking point, ·see the section “status display” later on·,
the error has been originated in some module of the system, not at the
RPS
power supply .
