Definition
OUTLoLIM
–5.0 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.
Use 0 % to 100 % for digital output type.
Use –5 % to 105 % for current position output.
I Hi LIM*
Within the range of the
output limits
HIGH RESET LIMIT—This is the highest value of output
beyond which you want no reset to occur.
I Lo LIM*
Within the range of the
output limits
LOW RESET LIMIT—This is the lowest value of output
beyond which you want no reset to occur.
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.
DEADBAND
–5.0 to 25.0 %
0.0 to 25.0 %
0.5 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).
Time Duplex
On-Off Duplex
Position Proportional and Three Position Step
*Reset limits and Dropoff are not displayed when Three Position Step Control is configured.
OUT HYST
0.0 to 100.0 % of PV span HYSTERESIS (OUTPUT RELAY) is an adjustable overlap
of the ON/OFF states of each control output. This is the
difference between the value of the process variable at
which the control outputs energize and the value at which
they de-energize.
Only applicable for ON/OFF control.
FAILMODE
NO LAT
LATCH
FAILSAFE MODE
NON LATCHING—Controller stays in last mode that was
being used (automatic or manual); output goes to failsafe
value. (NOTE 1, NOTE 2)
LATCHING—Controller goes to manual mode; output
goes to failsafe value. (NOTE 2)
FAILSAFE
0 to 100 % FAILSAFE OUTPUT VALUE—The value used here will
also be the output level when you have Communications
SHED set to failsafe or when NO BURNOUT is configured
and Input 1 fails.
Applies for all output types except 3 Position Step.
0 PCT
100PCT
THREE POSITION STEP FAILSAFE OUTPUT
0 PCT—Motor goes to closed position.
100PCT—Motor goes to open position.
SW_FAIL
0 OCT
100 PCT
PDMR/Position Proportional motor position when slidewire
fails.
0 PCT—Motor goes to closed position.
100PCT—Motor goes to open position.
Note: PWR OUT must be configured for FSAF.
