HIGH CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field
The HIGH CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field indicates the maximum relative humidity at this sensor for which the logical unit
should be operated. If the EWASC bit is set to one in the Information Exceptions Control mode page (see SBC-4, SSC-4, or SMC-3) and the asso
-
ciated current relative humidity (see 5.2.7.3) is greater than the value in the HIGH CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field, then the
device server shall report an informational exception condition with the additional sense code set to WARNING - HIGH CRITICAL HUMIDITY
LIMIT EXCEEDED.
HIGH CRITICAL RELATIVE HUMIDITY LIMIT RESET field
The HIGH CRITICAL RELATIVE HUMIDITY LIMIT RESET field indicates the relative humidity at which the informational exception condition for a
high critical relative humidity limit, if any, shall be cleared.
LOW CRITICAL RELATIVE HUMIDITY LIMIT RESET field
The LOW CRITICAL RELATIVE HUMIDITY LIMIT RESET field indicates the relative humidity at which the informational exception condition for a
low critical relative humidity limit, if any, shall be cleared.
LOW CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field
The LOW CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field indicates the minimum relative humidity at this sensor for which the logical unit
should be operated. If the EWASC bit is set to one in the Information Exceptions Control mode page (see SBC-4, SSC-4, or SMC-3) and the asso
-
ciated current relative humidity (see 5.2.7.3) is less than the value in the LOW CRITICAL RELATIVE HUMIDITY LIMIT TRIGGER field, then the
device server shall report an informational exception condition with the additional sense code set to WARNING - LOW CRITICAL HUMIDITY
LIMIT EXCEEDED.
HIGH OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field
The HIGH OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field indicates the maximum relative humidity at this sensor for which the logical
unit is capable of operating continuously without degrading the reliability beyond manufacturer accepted limits. If the EWASC bit is set to one
in the Information Exceptions Control mode page (see SBC-4, SSC-4, or SMC-3) and the associated current relative humidity (see 5.2.7.3) is
greater than the value of the HIGH OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field, then the device server shall report an informational
exception condition with the additional sense code set to WARNING - HIGH OPERATING HUMIDITY LIMIT EXCEEDED.
HIGH OPERATING RELATIVE HUMIDITY LIMIT RESET field
The HIGH OPERATING RELATIVE HUMIDITY LIMIT RESET field indicates the relative humidity at which the informational exception condition for
the associated high critical relative humidity limit, if any, shall be cleared.
LOW OPERATING RELATIVE HUMIDITY LIMIT RESET field
The LOW OPERATING RELATIVE HUMIDITY LIMIT RESET field indicates the relative humidity at which the informational exception condition for
the associated low critical relative humidity limit, if any, shall be cleared.
LOW OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field
The LOW OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field indicates the minimum relative humidity at this sensor for which the logical unit
is capable of operating continuously without degrading the logical unit's reliability beyond manufacturer accepted limits. If the EWASC bit is
set to one in the Information Exceptions Control mode page (see SBC-4, SSC-4, or SMC-3) and the associated current relative humidity
(see
5.2.7.3) is less than the value of the LOW OPERATING RELATIVE HUMIDITY LIMIT TRIGGER field, then the device server shall report an informa-
tional exception condition with the additional sense code set to WARNING - LOW OPERATING HUMIDITY LIMIT EXCEEDED.
