If your control is not equipped with Set Point 2, then proceed to the alarm section
(next page).
S 2 t
Set Point 2 type: Select
A b S
or
d E
.
A b S
Absolute
S P 2
.
S P 2
is independent of
S P 1
, and may be set anywhere
between the limits of
S P L
and
S P H
.
d E
Deviation
S P 2
.
S P 2
is set as a deviation from
S P 1
, and allows
S P 2
to
retain its relationship with
S P 1
when
S P 1
is changed (
S P 2
tracks
S P 1
).
S 2 S t
Set Point 2 State: Select
d i r
or
r E
.
d i r
Direct Action. As the input increases the output will increase. Most
commonly used in cooling processes.
r E
Reverse Action. As the input increases the output will decrease. Most
commonly used in heating processes.
If
O u t 2
is set for # #
t P
, #
P U L
, or
P r o P
,
then
S 2 O L
and
S 2 O H
appear. If
O u t 2
is set for
O n O F
, then skip
S 2 O L
and
S 2 O H
.
S 2 O L
Set Point Output Low Limit: Select
0
to
1 0 0
% but not greater than
S 2 O H
. 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 and 3. Factory set to
2 0
for
output code 5 (20% output equals 4 mA output).
S 2 O H
Set Point 2 Output High Limit: Select
0
to
1 0 0
% but not less than
S 2 O L
for output
codes 1 and 3. Select
0
to
1 0 2
% but not less than
S 2 O L
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
1 0 0
for all output codes.
If
O u t 2
is set to
O n O F
(in the Secondary Menu), then the next three menu items can make
the
S P 2
and
S P 2 d
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 the next pages.
Note that when Set Point 2 Power Interrupt ,
S 2 P i
is
O n
, and Set Point 2 Reset,
S 2 r E
, is
programmed to
H o l d
, the SP2 output will automatically reset upon a power failure and
subsequent restoration, if the process is below
S P 2
.
