11.8.14. Read the Operational Condition Event Register
This is a settings and modes event register, which means bits are set to "1" when a
condition occurs and they are not cleared until the register value is read or the *CLS
command is sent. For the condition to be latched as an event, the event bit must be
enabled as described in section 11.8.13 above.
The bit assignments are the same as the Operational Condition Condition Register,
described in section 11.8.12 above.

11.8.15. Read the Questionable Condition Condition Register
This register reports fault conditions which will cause the power supply output to turn
off. The faults include:
 User settable faults (enable, shut-down, over-voltage, fold-back, output off).
 Environmental faults (over-temperature, AC fail).
 Internal firmware faults (four faults).
This is a conditional register. The bits are set to "1" when the fault occurs and cleared
when the fault is cleared. The values are read-only. See the Genesys™ Technical
Manual for more details on faults.
These are the bit assignments of the Questionable Condition Condition Register:
