S1Pi Set Point 1 Power Interrupt. Select 0n or 0FF.
0n
Alarm Power Interrupt is
0n. Output will automatically
reset on power-up if no alarm condition exists.
0FF
Alarm Power Interrupt is
0FF. Output will be in the
alarm condition on power-up regardless of condition of
process.
S1iH Set Point 1 Inhibit: Select 0n or 0FF.
0n
Alarm Inhibit is On. Alarm action is suspended until the
process value first enters a non-alarm condition.
0FF
Alarm Inhibit is OFF.
S1LP Set Point Lamp: Select 0 on or 0oFF.
0 on Lamp ON when Output is ON.
0oFF Lamp OFF when Output is ON.
If your control is not equipped with Set Point 2, then proceed to the
alarm section (next page).
S2t
Set Point 2 type: Select
Ab
or
dE.
AbS
Absolute
SP2. SP2 is independent of SP1, and may be
set anywhere between the limits of
SPL and SPH.
dE
Deviation
SP2. SP2 is set as a deviation from SP1, and
allows
SP2 to retain its relationship with SP1 when SP1
is changed (
SP2 tracks SP1).
S2St Set Point 2 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
0ut2 is set for ##tP, #PUL, or ProP, then S20L and S20H appear. If 0ut2
is set for
0n 00F, then skip S20L and S20H.
S20L Set Point Output Low Limit: Select 0 to 100% but not greater than
S20H. 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, 4, and 8. Factory set to 20 for output code 5
(20% output equals 4 mA output).
S20H Set Point 2 Output High Limit: Select 0 to 100% but not less than
S20L for output codes 1, 2, 3, 4, or 8. Select 0 to 102% but not
less than S20L 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
