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 .
