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 Out2 is set for ##tP, #PUL, or ProP,then S2OL and S2OH (following)
appear. If Out2 is set for ONOF, then skip to S2rE.
S2OL Set Point Output Low Limit: Select 0 to 100% but not greater than
S2OH. 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).
S2OH Set Point 1 Output High Limit: Select 0 to 100% but not less than
S2OL for output codes 1, 2, or 3. Select 0 to 102% but not less than
S2OL for output code 5. This item allows setting the maximum
output limit. This is useful with processes that are over powered.
Adjustment to 102% allows setting current output to force a full on
condition for output devices which do not have bias adjustments.
Factory set to 100 for all output codes.
S2rE Set Point 2 Reset. Select OnOF or Hold.
OnOF
Control will automatically reset when process passes
