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.
If
0ut1 (Page 21) is set for ##tP, #PUL, or ProP, then S10L and S10L
appear. If
0ut1 is set for 0n0F, then skip S1rE.
S10L Set Point Output Low Limit. Select 0 to 100% but not greater than S10H.
This item limits the lowest output value. This is useful for adding a bias to
the process when needed. Factory set to 0 for outputs codes 1, 2, 3, 4,
and 8. Factory set to 20 for output code 5 (20% out put equals 4 mA
output).
S10H Set Point 1 Output High Limit. Select 0 to 100% but not less than S10L
for output codes 1, 2, 3, 4, or 8. Select 0 to 102% but not less than
S10L 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 seeting 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.
If
0ut1 is set for ##tP, #PUL, or ProP, then skip to S1LP below.
If
0ut1 is set to 0n0F (in Secondary Menu), then the next three menu items can
make the
SP1 and SP1d settings act like a high or low alarm set point. See the
information on alarm settings and the cautions and warnings that apply to them on
Pages 30-31.
Note that when Set Point 1 Power Interrupt,
S1P, is 0n, and Set Point 1 Reset,
S1rE, is programmed to HoLd, the SP1 output will automatically reset upon a
power failure and subsequent restoration, if the process is below
SP1.
S1rE Set Point 1 Reset. Select 0n0F or HoLd.
0n0F Output will automatically reset when process passes back
through
SP1d.
HoLd Manual Reset. Reset by simultaneously pressing the
INDEX & DOWN ARROW keys for 3 seconds.
