START
KEY
ALARM 2
START
allows you to select whether the timer starts
with the keyboard (Run/Hold key) or Alarm 2.
LOW DISP
TI REM
E TIME
LOW DISP
allows you to select whether time
remaining (TI REM) or elapsed time (E TIME) is
displayed for the timer option.
The time is shown on the lower display in HH:MM
format along with a rotating “clock” character.
• If the “clock” rotation is
clockwise,
elapsed time is
indicated.
• If the “clock” rotation is
counterclockwise,
time
remaining is indicated.
INPUT MATH ALGORITHMS
—Controllers with two inputs are provided with one input algorithm. Unless
otherwise noted, these selections are provided only as part of the Math Options package. Each algorithm
can be configured to provide a derived (calculated) PV or a derived Remote Setpoint. Up to three inputs
may be applied to the calculation. See Inputs A, B, and C for definitions per equation.
All algorithms operate in engineering units except Feedforward (F FWRD) which operates in percent of
output units.
ATTENTION
When the Input C configuration is set to NONE, the value of Input C used in the functions
is automatically set to 1.0, except for the Summer algorithm, where it is set to 0.0.
INP ALG1
INPUT ALGORITHM 1
has the following selections
from which to choose:
NONE
NONE
—No algorithm configured
(See Note 2)
(Standard feature on
controllers with two
analog inputs)
WEIGHTED AVERAGE
—When you configure for
Weighted Average, the controller will compute a PV
or SP for the control algorithm from the following
equation:
Alg1 = [(Input A x Ratio A + Bias A) + (K x Input B x Ratio B + Bias B)] / (1 + K)] +
Alg1Bias
F FWRD
(Standard feature on
controllers with two
analog inputs)
FEEDFORWARD SUMMER
—Feedforward uses
Input A, following a Ratio and Bias calculation as a
value summed directly with the PID computed output
value and sent, as an output value, to the final
control element.
This algorithm will only function in automatic mode
and is not used for Three Position Step Control
applications.
The following formula applies:
Controller Output = PID (Input A x Ratio A + Bias A ) x (100 / Input A
Range)
