SCH1 Scale High: Select 100 to 9999 counts above SCL1. The total span between SCL1 and SCH1 must be within 11998 counts. Maximum setting range is -1999to +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.

SPL1 Set Point Low: Select from the lowest input range value to SPH1 value. This will set the minimum SP1 value that can be entered. The value for SP1 will not stop moving when this value is reached. Attempting to set a value for SP1 lower than SPL1 will result in a CHEC SP1 error. The value will not be accepted.

SPH1 Set Point High: Select from the highest input range value to SPL1 value. This will set the maximum SP1 value that can be entered. The value for SP1 will not stop moving when this value is reached. Attempting to set a value for SP1 higher than SPH1 will result in a CHEC SP1 error. The value will not be accepted.

S1St Set Point 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 (following) appear.

##tP, #PUL, or ProP, then S1OL and S1OH If Out1 is set for ONOF, then skip to S1rE.

S1OL Set Point Output Low Limit: Select 0 to 90% 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, 3, and 8. Factory set to 20 for output code 5 (20% output equals 4 mA output).

S1OH Set Point Output High Limit: Select 10 to 100% but not less than S1OL for output codes 1, 2, 3, or 8. Select 10 to 102% but not less than S1OL 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
