than the fastest process response expected during a 1 second
period, but measured for at least 2 seconds. If the process is faster
than this setting, the SEnC bAd error message will appear. The
outputs will then be turned off. This function can be used to detect
a runaway condition, or speed up detection of an open thermo-
couple. Use the INDEX & ENTER keys to reset.
SCAL
Scale Low: Select 100 to 9999 counts below SCAH. The total span
between SCAL and SCAH must be within 11998 counts. Maximum
setting range is -1999 to +9999 counts. For Current and Voltage
inputs, this will set the low range end. Viewable only for Thermo-
couple and RTD ranges.
SCAH
Scale High: Select 100 to 9999 counts above SCAL. The total span
between SCAL and SCAH must be within 11998 counts. Maximum
setting range is -1999 to +9999 counts. For Current and Voltage
inputs, this will set the high range end. Viewable only for Thermo-
couple and RTD ranges.
SPL
Set Point Low: Select from the lowest input range value to SPH
value. This will set the minimum SP1 or SP2 value that can be
entered. The value for SP1 or SP2 will not stop moving when this
value is reached.
SPH
Set Point High: Select from the highest input range value to SPL
value. This will set the maximum SP1 or SP2 value that can be
entered. The value for SP1 or SP2 will not stop moving when this
value is reached.
S1St
Set Point 1 State: Select dir or rE.
dir
Direct Action. As the input increases the output will
increase. Most commonly used in cooling processes.
rE
Reverse Action. As the input increases the output will
decrease. Most commonly used in heating processes.
If Out1 is set for ##tP, #PUL, or ProP,then S1OL and S1OH (following)
appear. If Out1 is set for ONOF, then skip to S1rE.
S1OL
Set Point Output Low Limit: Select 0 to 100% but not greater than
S1OH. This item limits the lowest output value. This is useful for
adding a bias to the process when needed. Factory set to 0 for
output codes 1,2, and 3. Factory set to 20 for output code 5 (20%
output equals 4 mA output).
