If your control is not equipped with a second output or if the second output is programmed as
an alarm, then proceed to the alarm section (next page).
S2t Set Point 2 type: Select Abs 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 (tracking SP2).
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 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 overpowered. 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 back through SP2d.
HoLd Manual Reset. Reset (acknowledge) by simultaneously pressing the INDEX &
DOWN ARROW keys for 5seconds.
S2Pi Set Point 2 Power Interrupt. Select On or OFF.
On
Alarm Power Interrupt is On. Control will automatically reset on power-up if no
alarm condition exists.
OFF Alarm Power Interrupt is OFF. Control will power-up in alarm condition regardless
of condition of process.
S2iH Set Point 2 Inhibit: Select On or OFF.
On
Alarm Inhibit is On. Alarm action is suspended until the process value first enters
a non-alarm condition.
OFF Alarm Inhibit is OFF.
S2LP Set Point 2 Lamp: Select O on or OoFF.
O on
Lamp ON when Output is ON.
OoFF Lamp OFF when Output is ON.
