Coef
Proportional Band Coefficient
The PID proportional coefficient between Output 1 and Output 2
when a dual output control is selected. The P value of Output 2 equals
the P value of Output 1 PID * Coef. The I and D value of Output 2's
PID are the same as Output 1's. Defualt value is 1.00.
dead
Deadband
The deadband around the SV value. For example, if SV = 100 degrees
and dead = 2.0, there will be no output when the temperature is
between 99~101°C. See PID and On/Off control sections in chapter 5.
Default value is 0.
pv-f
PV Filter
The process value filter takes the input and applies a rolling average
to compensate for noisy signals. Filter equation: (Last displayed PV
* Pv-f + Current Measurement) / (Pv-f+1). Range of 0 to 50 with a
system default of 2.
pv-r
PV Filter Range
Process value filter range is the plus or minus range from the last
displayed PV that PV Filtering will be applied. For very noisy signals
the number must be large enough to capture large oscillations in
signal. Range of 0.10 to 10.00 degrees with a system default of 1.
pvof
PV Offset
The PV Offset is the amount added to the current process value. Range of
-99.9 to 99.9 with a system default of 0.
Pv6a
PV Gain
The PV Gain is the multiplier applied to the current process value. Range
of -0.999 to 0.999 with a system default of 0. Gain equation: PV = Current
Measurement * (1 + Pv6a / 1.000) + Pvof.
a1ma
Analog High Adjustment
The Analog High Adjustment value is added to the maximum analog
output of 20ma in 1uA increments. If set to 500 the output will be
20.5ma at 100 percent output. Range of -3895 to 659 with a system
default of 0. This parameter is only available on Current Output models.
00.
a1mi
Analog Low Adjustment
The Analog Low Adjustment value is added to the minimum analog
output of 4ma in 1uA increments. If set to -100 the output will be
3.9ma at 0 percent output. Range of -964 to 3895 with a system
default of 0.
This parameter is only available on Current Output models.
