SCH2 SCH2 SCH2 SCH2 SCH2 Scale High: Select 100 to 9999 counts above SCL2 SCL2 SCL2 SCL2 SCL2 . The total
span between SCL2 and SCH2 must be within 11998 counts.
Maximum setting range is -1999 to +9999 counts. Minimum
span is 100 counts. For Current and Voltage inputs, this will
set the high range end. Viewable only for Thermocouple and
RTD ranges.
SPL2 SPL2 SPL2 SPL2 SPL2 Set Point Low: Select from the lowest input range value to
SPH1 value. This will set the minimum
SP2 value that can
be entered. The value for SP2 will not stop moving when this
value is reached. Attempting to set a value for SP2 lower
than SPL2 will result in a CHEC SP2 error. The value will not
be accepted.
SPH2 SPH2 SPH2 SPH2 SPH2 Set Point High: Select from the highest input range value to
SPL2 value. This will set the maximum
SP2 value that can
be entered. The value for SP2 will not stop moving when this
value is reached. Attempting to set a value for
SP2 higher
than SPH2 will result in a CHEC SP2 error. The value will not
be accepted.
S2St S2St S2St S2St S2St Set Point State: Select dir dir dir dir dir or rE rE rE rE rE .
dir dir dir dir dir Direct Action. As the input increases the output
will increase. Most commonly used in cooling
processes.
rE rE rE rE rE Reverse Action. As the input increases the output
will decrease. Most commonly used in heating
processes.
If Out2 Out2 Out2 Out2 Out2 is set for ## tP tP tP tP tP , or # PUL PUL PUL PUL PUL , then S2OH S2OH S2OH S2OH S2OH and S2OH S2OH S2OH S2OH S2OH (following)
appear. If Out2 Out2 Out2 Out2 Out2 is set for ONOF ONOF ONOF ONOF ONOF , then skip to S2rE S2rE S2rE S2rE S2rE .
S2OL S2OL S2OL S2OL S2OL Set Point Output Low Limit: Select 0 00 00 to 90 90 90 90 90 % but not greater
than S2OH S2OH S2OH S2OH S2OH . This item limits the lowest output value. This is
useful for adding a bias to the process when needed.
Factory set to
0 00 00 for output codes 1,2, 3, and 8. Factory set
to 20 20 20 20 20 for output code 5 (20% output equals 4 mA output).
S2OH S2OH S2OH S2OH S2OH Set Point 1 Output High Limit: Select 10 10 10 10 10 to 100 100 100 100 100 % but not less
than S2OL S2OL S2OL S2OL S2OL for output codes 1, 2, 3, or 8. Select 10 10 10 10 10 to 102 102 102 102 102 %
but not less than S2OL S2OL S2OL S2OL S2OL for output code 5. This item allows
setting the maximum output limit. This is useful with pro-
cesses that are over powered. Adjustment to
102 % allows
setting current output to force a full on condition for output
