OUT.LO Selected temperature value for 0% output for IN.TYPE = TEMP
in units defined by the UNIT parameter (°C or °F)
Range is defined by the selected temperature sensor (SENSOR
and TC.TYPE, Ni.TYPE or Pt.TYPE), but value must be less than
OUT.HI - minimum span.
OUT.HI Selected temperature value for 100% output for IN.TYPE =
TEMP in units defined by the UNIT parameter (°C or °F).
Range is defined by the selected temperature sensor (SENSOR
and TC.TYPE, Ni.TYPE or Pt.TYPE), but must be larger than
OUT.LO + minimum span.
RESP Analogue output response time in seconds.
Range is 0.0 to 60.0 seconds.
USE.CAL Use the applied process calibration values:
NO = The last performed process calibration is not used. The
channel operates with accuracy as specified.
YES = The last performed process calibration is in operation.
The required accuracy must be verified by user.
End user must verify by test that the applied process calibration
does not introduce failures exceeding the requirements for the
safety application.
Note
5
:
Value not allowed if analogue output is used in a safety application (EN.SIL =
YES) and IN.TYPE = CURR and loop supply is used to supply a current input signal.
Note
6
: Error detection is enabled if ERR.ACT ≠ NONE, but analogue output value
is undefined.
14.2. Verification procedure
The verification is done using the display / programming front PR 4501 and
following the procedure described below.
