CAUTION!
External User Control interface signals are isolated from negative output terminal;
Isolation voltage is rated for
±
600 V
RMS
, maximum; operation of Isolated Analog
Interface signals should be at SELV safety voltage conditions to chassis ground.

Fault
Hight state in the following pin indicates the Fault in the power supply. Fault Signal Pin is 3
and return is 8 for Channel 1, pin 12 and return is 17 for Channel 2 and pin 21 and return is
26 for Channel 3. Fault Signal Pin become High whenever there is a fault recorded in the
Protection Condition Register. An exception to this Constant Voltage Operation (Bit 0),
Constant Current Operation (Bit 1) and Constant Power Operation (Bit 2), as they indicate
the operating status of the power supply.
Low state: 0.3 V max
High state: Minimum 3V and Maximum Current is 0.5 A
Following is the list of faults that can be generated:
