Lights indicating the status of the main power supply
The non-regenerative power supply PS-25B4 has the following lights on
the front panel to indicate the status of the main power supply.
FAULT blinking.
The blinking red led indicates that
there are no er-
rors
and that
one or several mains phases are missing
.
FAULT turned ON.
The steady red led on indicates that there is an er-
ror. The error is indicated on the display of the drive modules.
FAULT turned OFF.
The led off indicates that there is no error and
that all mains phases are OK.
BALLAST turned ON.
The amber led is lit when the energy dissipat-
ing Ballast circuit is activated.
DC BUS ON.
The green led indicates that the module is supplying all
its power at the bus.
Lights indicating the status of the auxiliary power supply
The non-regenerative power supply PS-25B4 has the following status indi-
cating lights on the front panel of the module for the integrated internal
auxiliary power supply.
RESET.
Initializes the auxiliary 24 V DC power supply.
OVER VOLTAGE.
The red led indicates that there is an over-voltage
error at the 24 V DC output or due to over-temperature.
OVER CURRENT.
The red led indicates that there is an over-current
error at the 24 V DC output.
ON.
The green led it indicates that there are 24 V DC at the output.
Ballast resistor selection
The non-regenerative power supply PS-25B4 had two switches on the
front and next to connector X1 (see figure) for selecting the external Bal-
last resistor. If you have a model like this one, refer to the attached table
to select the right resistor model according to the setting of the switches
that enables the “I²t” protection. Remember that selecting the internal re-
sistor or having the RM-15 module means disabling the “I²t” protection be-
cause they both include their own thermostat for their own protection.
For the switch combination shown in the figure and verified in the table,
the selected ballast resistor would correspond to the ER-18/1800 or
ER+TH-18/1000+FAN.
NOTE.
The model with two selection switches has been discontinued. If
you still have this model, refer to this section to configure the selection
of the Ballast resistor. If you have the model with three switches, see the
next page.
