returns to the decimal point range, the display will
autorange back to tenth dergee resolution.
InPt Input Fault Timer: Select OFF, 0.1 to 540.0 minutes. Whenever an
Input is out of range (UFL or OFL displayed), shorted, or open the
timer will start. When the time has elapsed, the controller will revert
to a safe condition (Output Off, Flashing Display). If OFF is
selected, the Input Fault Timer will not be recognized (time =
infinite).
SPL Set Point Low: Select from the lowest input range value to SPH
value. This will set the minimum SP value that can be entered. The
value for SP will 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 SP value that can be entered. The
value for SP will stop moving when this value is reached.
SPSt 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.
SPOL Set Point Output Low Limit: Select 0 to 100% but not greater than
SPOH. 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).
SPOH Set Point Output High Limit: Select 0 to 100% but not less than
SPOL for output codes 1, 2, or 3. Select 0 to 102% but not less
than SPOL 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.
SPLP Set Point Lamp: Select O on or OoFF.
O on
Lamp ON when Output is ON.
OoFF Lamp OFF when Output is ON.
