LiAM User's Manual
"Activity" LED
The LEDs are indicators of the power supply status and have to be interpreted
as follows:
FAULT LED: the
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 unit
status register reset has been performed and the cause of the fault has been
removed;
DIAGNOSTICS LED: the
control electronics at every diagnostic routine execution. If this LED is not
toggling between on and off state, the internal diagnostics is not correctly
executed by the module;
AC OK LED: the
modules are correctly working;
OUTPUT LED: the
and it is correctly regulating the output current;
It is important to notice that the blue OUTPUT light and the red FAULT light
cannot be 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 turned off.
The "RESET" hole, accessible by using a small screw-driver, allows
performing a re-initialization of the LiAM internal firmware.
3.1.1 Internal Protections
Each LiAM module is equipped with multiple internal protections (hardware
and software) to avoid unwanted behaviors or eventual damages to the unit and also to
let users run the power supply safely.
All hardware protections are installed into the LiAM power units and are here
listed:
CB (CrowBar protection);
