Programming The
Tolerance Limits
The various SENSE commands are used to set the
programmable tolerance limits for the various attributes
monitored by the 1269 EMS. The following paragraphs
describe how to set each attribute’s tolerance limit or limits.
Refer to
Table 5-2
for a description of the range of values
accepted for each command.
Programming The
Power Supply Voltage
Tolerance Limits
The power supply voltages are monitored to ensure that they
are between an upper and a lower limit. The lower voltage
tolerance limit is always the most negative, and the upper
voltage tolerance limit is always the most positive. The
following commands may be used to set the power supply
voltage tolerance limits:
SENSE:VOLT1:RANGE:UPPER 5.2
-- +5V upper limit
SENSE:VOLT1:RANGE:LOWER 4.8
-- +5V lower limit
SENSE:VOLT2:RANGE:UPPER -5.0
-- -5.2V upper limit
SENSE:VOLT2:RANGE:LOWER -5.4
-- -5.2V lower limit
SENSE:VOLT3:RANGE:UPPER -1.8
-- -2V upper limit
SENSE:VOLT3:RANGE:LOWER -2.2
-- -2V lower limit
SENSE:VOLT4:RANGE:UPPER 25.9
-- +24V upper limit
SENSE:VOLT4:RANGE:LOWER 23.1
-- +24V lower limit
SENSE:VOLT5:RANGE:UPPER -23.1
-- -24V upper limit
SENSE:VOLT5:RANGE:LOWER -25.9
-- -24V lower limit
SENSE:VOLT6:RANGE:UPPER 12.9
-- +12V upper limit
SENSE:VOLT1:RANGE:LOWER 11.1
-- +12V lower limit
SENSE:VOLT7:RANGE:UPPER -11.1
-- -12V upper limit
SENSE:VOLT7:RANGE:LOWER -12.9
-- -12V lower limit
Each of these commands has an associated query. For
example, the query:
SENSE:VOLT5:RANGE:LOWER?
reads the lower voltage tolerance limit for the -24V Power
Supply. Refer to
Table 5-2
for a description of a range of
values accepted for this command.
