If O u t 1 (Page 19) is set for # # t P , # P U L , or P r o P , then S 1 O L and S 1 O H appear. If O u t 1 is set
for O n O F , then skip to S 1 r E .
S 1 O L Set Point Output Low Limit: Select 0 to 1 0 0 % but not greater than S 1 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 1 O H Set Point 1 Output High Limit: Select 0 to 1 0 0 % but not less than S 1 O L for output
codes 1 and 3. Select 0 to 1 0 2 % but not less than S 1 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 1 is set for # # t P , # P U L , or P r o P , then skip to S 1 L P (next page).
If O u t 1 is set to O n O F (in the Secondary Menu), then the next three menu items can make
the S P 1 and S P 1 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 Pages 36-37.
Note that when Set Point 1 Power Interrupt , S 1 P i is O n , and Set Point 1 Reset, S 1 r E , is
programmed to H o L d , the SP1 output will automatically reset upon a power failure and
subsequent restoration, if the process is below S P 1 .
S 1 r E Set Point 1 Reset. Select O n O F or H o L d .
O n O F
Output will automatically reset when process passes back through S P 1 d .
H o L d Manual Reset. Reset (acknowledge) by simultaneously pressing the
INDEX & DOWN ARROW keys for 3 seconds.
S 1 P i Set Point 1 Power Interrupt. Select O n or O F F .
O n
Alarm Power Interrupt is O n . Output will automatically reset on
power-up if no alarm condition exists.
O F F Alarm Power Interrupt is O F F . Output will be in the alarm condition on
power-up regardless of condition of process.
S 1 i H Set Point 1 Inhibit: Select O n or O F F .
O n
Alarm Inhibit is O n . Alarm action is suspended until the process value
first enters a non-alarm condition.
O F F Alarm Inhibit is O F F .
S 1 L P Set Point Lamp: Select O o n or O o F F .
O o n
Lamp ON when Output is ON.
O o F F Lamp OFF when Output is ON.
