FAULT CONDITION POWER VALUE
-199.9
to
200.0
%
Enter the desired control output value for the controller to assume
in the event that the input sensor fails. You may enter values in excess
of 100% and -100% to overcome limitations caused by Power
Transfer Values, such as Gains and Offsets, that would otherwise
limit the output to less than their maximums.
OUTPUT DEADBAND
-100.0
to
100.0
%
The Output Deadband property defines the area in which both the
heating and cooling outputs are inactive, known as deadband, or the
area in which they will both be active, known as overlap. A positive
value results in a deadband, while a negative value results in an
overlap.
OUTPUT HEAT GAIN
0
to
500.0
%
The Output Heat Gain defines the gain of the heating output
relative to the gain established by the Proportional Band. A value of
100% causes the heat gain to mimic the gain determined by the
proportional band. A value less than 100% can be used in applications
in which the heater is oversized, while a value greater than 100% can
be used when the heater is undersized. For the majority of applications the
default value of 100% is adequate, and adjustments should only be made if the
process requires it.
HEAT POWER LOW AND HIGH LIMITS
0
to
200.0
%
The Heat Low Limit and Heat High Limit properties may be used
to limit controller power due to process disturbances or setpoint
changes. Enter the safe output power limits for the process. You may
enter values in excess of 100% to overcome limitations caused by
power transfer values, such as gains and offsets, which would
otherwise limit the output to less than their maximums.
OUTPUT COOL GAIN
0
to
500.0
%
The Output Cool Gain defines the gain of the cooling output
relative to the gain established by the Proportional Band. A value of
100% causes the cool gain to mimic the gain determined by the
proportional band. A value less than 100% can be used in applications
in which the cooling device is oversized, while a value greater than
100% can be used when the cooling device is undersized. For the majority of
applications the default value of 100% is adequate, and adjustments should only
be made if the process requires it.
COOL POWER LOW AND HIGH LIMITS

200.0
%
The Cool Low Limit and Cool High Limit properties may be used
to limit controller power due to process disturbances or setpoint
changes. Enter the safe output power limits for the process. You may
enter values in excess of –100% to overcome limitations caused by
power transfer values, such as gains and offsets, which would
otherwise limit the output to less than their maximums.
