OUTPUT CHANGE RATE—Enables or disables the
Output Change Rate. The maximum rate is set at prompt
PCT/M UP or PCT/M DN.
Output Change Rate. The maximum rate is set at prompt
PCT/M UP or PCT/M DN.
DISABLE—Disables output rate.
ENABLE—Allows output rate.
ENABLE—Allows 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.
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.
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.
OUT HiLIM
–5 to 105 % of output
HIGH OUTPUT LIMIT—This is the highest value of output
beyond which you do not want the controller automatic
output to exceed.
beyond which you do not want the controller automatic
output to exceed.
Use 0 to 100 % for digital output type.
Use 5 to 105 % for current output.
Use 5 to 105 % for current output.
OUT LoLIM
–5 to 105 % of output
LOW OUTPUT LIMIT—This is the lowest value of output
below which you do not want the controller automatic
output to exceed.
below which you do not want the controller automatic
output to exceed.
Use 0 % to 100 % for digital output type.
Use 5 % to 105 % for current output.
Use 5 % to 105 % for current output.
*The Local Setpoint will automatically adjust itself to be within the setpoint limit range. For example, if SP = 1500 and
the SP HiLIM is changed to 1200, the new Local Setpoint will be 1200.
the SP HiLIM is changed to 1200, the new Local Setpoint will be 1200.

DROPOFF
–5 to 105 % of output
CONTROLLER DROPOFF VALUE—Output value below
which the controller output will drop off to the low output
limit value set in prompt OUTLoLIM.
which the controller output will drop off to the low output
limit value set in prompt OUTLoLIM.
DEADBAND
–5.0 to 5.0 %
DEADBAND is an adjustable gap between the operating
ranges of output 1 and output 2 in which neither output
operates (positive value) or both outputs operate (negative
value).
ranges of output 1 and output 2 in which neither output
operates (positive value) or both outputs operate (negative

FAILSAFE MODE
NON LATCHING—Controller stays in last mode
(automatic or manual); output goes to failsafe value.
(automatic or manual); output goes to failsafe value.
LATCHING—Controller goes to manual mode; output
