EASY-DRIVER – User’s Manual
12
DC Output connectors are terminal-type ones that allows for easily connecting
direct cables (suggested cross sectional area for load cables is rated at 6 mm
2
, or AWG
10 – AWG 9).
The output connection terminal direction is indicated as shown in
Figure 3
.

The LEDs, visible from the power unit front panel (shown in
Figure 4
), are
indicators of the power supply status and have to be interpreted as follows:
•
DC LINK
LED: the green light indicates that the bulk power supply is working
correctly;
•
AUX PS
LED: the green light indicates that the control electronic section
voltage – i.e. 3.3V, directly obtained from auxiliary AC/DC – is correctly
working;
•
RX
LED: the green light toggles at every character reception and it is a
communication heartbeat indicator;
•
DIAG
LED: the green light toggles at every diagnostic routine execution. If this
LED is not toggling, the internal diagnostic routines are not correctly performed
by the module.
•
ON
LED: the blue light indicates that the EASY-DRIVER output turned on and
it is correctly regulating output current;
•
FAULT
LED: the red light indicates that the power supply has experienced a
generic fault that can be either an internal protection trip or an external interlock
intervention. This light does not turn off after a fault until a module reset has
been performed.
It is important to notice that the blue ON light and the red FAULT light cannot
be turned on at the same moment because the module cannot correctly regulate output
current if a fault is experienced and the output stage of the power supply is disabled.
