This field is factory defined as LIAM_XXXXXX where XXXXXX are digits (0 to
9) representing the serial number of the power supply module.
The second line shows the internal readback of the module actual output
current value with a resolution of 100 µA on the displayed value.
The third line shows the internal readback of the module actual output voltage
value with a resolution of 100 µV on the displayed value.
The fourth line indicates the status of the power supply unit. This status can be
one of the following:
-
OK: the module is correctly operating;
-
FAULT: the module has experienced a fault condition.
The fault condition can be caused by either an internal protection trip (e.g. AC
fault, over-temperature condition, etc.) or an external fault – i.e. external interlocks.
The "Status: FAULT" indication is always combined with the red FAULT
light lit up on the module front panel. A remote reset of the power supply status
register must be performed in order to clear this status (only if the conditions that
generated the fault had been removed).
Please note that the "Status: OK" indication does not indicate that the module
is turned on and/or sinking/sourcing current to the load (the indication of the "ON"
status of the power unit can be monitored by the blue OUTPUT light on the front
panel).
