If
0ut1
(Page 21) is set for ##
tP
, #
PUL
, or
ProP
, then
S10L
and
S10L
appear. If
0ut1
is set for

, 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

S1rE
, is programmed to

, 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

or
HoLd
.
0n0F
Output will automatically reset when process passes back
through
