Status indicator lamps
The non-regenerative power supply PS-65A 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
errors and that one or several mains phases are missing.
 FAULT turned ON. The steady red led on indicates that there is an
error. The error is indicated on the display of the drives.
 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 dissipating
Ballast circuit is activated.
 DC BUS ON.The green led indicates that the module is supplying all its
power at the DC BUS.
INFORMATION. For further detail on these indicator lights, see the combi-
i
nation table for interpretation in the description of the E305 code on the er-
ror listing shown in chapter 14 of the "man_dds_soft.pdf" manual.
Ballast resistor selection
Non-regenerative power supplies PS-65A have three dip-switches on top,
next to the terminal strip for mains connection (see figure) for selecting the
external Ballast resistor. Refer to the attached table to make the type selec-
tion properly according to the setting of the switches while the «I²t» protec-
tion stays enabled.

WARNING. When installing a NON-FAGOR resistor, only use this switch
setting when the power of your resistor is greater than any of the ones
shown in this cell of the tables provided by FAGOR. Ignoring this warning
MAY CAUSE THE DESTRUCTION of the resistor WITHOUT PRIOR
WARNING. Therefore, make sure to install your own protection system
when installing a NON-FAGOR resistor of lower power.
Example
For the switch combination shown in the figure and verified in the table, the
Ballast Resistor selected would correspond to the 2x ER+TH-18/1800.
