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:
Blinking FAULT. 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 mains voltage. 0 state of the operating
modes.
FAULT turned 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.
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.
FAULT turned 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. 1 state of the operating modes.
REGEN. Amber LED on. It indicates that the module is working in energy
regenerating (returning to mains) mode. (3 state 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.
