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 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.
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
selection properly according to the setting of the switches while the i2t
protection stays enabled.
Selecting “internal resistor or RM-15 module (already discontinued)” im-
plies disabling the I2t protection. There is no risk of destroying the resis-
tor because they both carry their own thermostat for their protection.
Selecting “resistor disabled” implies disablilng the I2t protection. There is
a risk of destroying the resistor without warning. Select only this switch
setting when installing a resistor of more power than the ones supplied by
FAGOR.
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.
INFORMATION. For further detail on these indicator lights, see the com-
bination table for interpretation in the description of the E305 code on the
error listing shown in chapter 14 of the “man_dds_soft.pdf” manual.
