Programming The
Fan Speed
Tolerance Limits
The fan speeds are monitored to ensure that they are between
the upper and lower limits. The following commands may be
used to set the fan speed tolerance limits.
SENSE:FREQ1:RANGE:UPPER 6500
-- all 3 fans, upper limit
SENSE:FREQ1:RANGE:LOWER 2000
-- all 3 fans, lower limit
SENSE:FREQ2:RANGE:UPPER 7220
-- fan #1, upper limit
SENSE:FREQ2:RANGE:LOWER 3120
-- fan #1, lower limit
SENSE:FREQ3:RANGE:UPPER 6970
-- fan #2, upper limit
SENSE:FREQ3:RANGE:LOWER 2870
-- fan #2, lower limit
SENSE:FREQ4:RANGE:UPPER 7220
-- fan #3, upper limit
SENSE:FREQ4:RANGE:LOWER 2650
-- fan #3, lower limit
Each of these commands has an associated query. For
example, the query:
SENSE:FREQ4:RANGE:LOWER?
reads the lower fan speed tolerance limit for fan #3. Refer to
Table
5-2
for a description of a range of values accepted for this
command.
Programming The
Ambient
Temperature
Tolerance Limits
The ambient temperature is monitored to ensure that it does not
exceed an upper limit. The following command may be used to
set the ambient temperature limit.
SENSE:TEMP14:RANGE:UPPER 63.0
This example sets the upper limit of the ambient temperature to
63 degrees Celsius. The present upper limit for the ambient
temperature may be read with the query:
SENSE:TEMP14:RANGE:UPPER?
Refer to
Table 5-2
for a description of a range of values
