SEnC
Sensor Rate of Change: Select OFF, 1 to 4000 °F, °C, or counts per 1 second period. This
value is usually set to be slightly greater 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
thermocouple. 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 Thermocouple
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 Thermocouple
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.
SP1O
Set Point 1 Output Select: Select OutA or Outb.
OutA
Set Point 1 is routed through Output A, Set Point 2 (if equipped) is routed through
Output B. Setting is forced to OutA if control is equipped with single output or if
second output is programmed as alarm.
Outb
Set Point 1 is routed through Output B, Set Point 2 (if equipped) is routed through
Output A.
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.
