PID-A, PID-B, PD+MR control algorithms.
ENABLE—Allows output rate.
DISABLE—Disables output rate.
PCT/M UP
0 to 9999 % per minute
OUTPUT RATE UP VALUE—This selection limits
the rate at which the output can change upward.
Enter a value in percent per minute. Appears only if
OUT RATE is enabled. “0” means no output rate
applied.
PCT/M DN
0 to 9999 % per minute
OUTPUT RATE DOWN VALUE—This selection
limits the rate at which the output can change
downward. Enter a value in percent per minute.
Appears only if OUT RATE is enabled. “0” means no
output rate.
OUTHiLIM
HIGH OUTPUT LIMIT—This is the highest value of
output beyond which you do not want the controller
automatic output to exceed.
0 % to 100 %
–5 % to 105 %
For relay output types.
For current output types
OUTLoLIM
LOW OUTPUT LIMIT—This is the lowest value of
output below which you do not want the controller
automatic output to exceed.
0 % to 100 %
–5 % to 105 %
For relay output types.
For current output types

output limits
HIGH RESET LIMIT—This is the highest value of
output beyond which you do not want reset action to
occur

(Note 4)
Within the range of the
output limits
LOW RESET LIMIT—This is the lowest value of
output beyond which you do not want reset action to
occur.
DROPOFF
(Note 4)

CONTROLLER DROPOFF VALUE—Output value
below which the controller output will drop off to the
low output limit value set in prompt OUTLoLIM.
DEADBAND
