CONFIGURATION PARAMETER EXPLANATIONS

Input Parameter Module (1- IN) CN63100 Models

The controller has several input set-up parameters that must be
programmed prior to setting any other controller parameters.

Input Type (tYPE)

Select from the list of various thermocouple and RTD sensors.
The following is a list of the possible sensors:
tc-t Type T TC
tc-E Type E TC
tc-J Type J TC
tc-k Type K TC
tc-r Type R TC
tc-S Type S TC
tc-b Type B TC
tc-N Type N TC
LIN Linear mV display
r385 385 curve RTD
r392 392 curve RTD
rLIN Linear ohms display

Temperature Scale (SCAL)

Select either degrees Fahrenheit (F) or degrees Celsius (C).
If changed, be sure to check all parameters.

Temperature Resolution (dCPt)

Select either 1 or 0.1 degree resolution.
If changed, be sure to check all parameters.

Digital Input Filtering and Display Update Rate (FLtr)

Select the relative degree of input signal filtering and display update rate.
The f ilter is an adaptive d igital f ilter that d iscriminates between
measurement noise and actual process changes. Therefore, the influence on
step response time is minimal. If the signal is varying too greatly due to
measurement noise, increase the filter value. Additionally, with large
derivative times, control action may be too unstable for accurate control.
Increase the filter value. Conversely, if the fastest controller response is
desired, decrease the filter value.
The Auto-tune procedure sets the filter value appropriate to the process
characteristics. Also see Output Power Dampening parameter (OPdP), page
35, for filtering the output.
Fltr- 0 to 4
0 = least input filtering
3 = most input filtering
4 = most input filtering and slower (500 msec) display update rate
(outputs update at 100 msec rate)

Input Sensor Correction Constant (SHFt)

If the controller temperature disagrees with a reference temperature
instrument or if the temperature sensor has a known calibration, the controller
temperature can be compensated by a correction offset (SHFt).
SHFt - -999 to 9999
The following equation expresses the relationship:
Desired Display Temp = (Controller Temp) + SHFt
Example 1: The controller reads 293°F while a reference instrument indicates
300°F. A SHFt value of +7°F corrects the controller indication to match the
reference.
Setpoint Limit Values (SPLO & SPHI)
The controller has programmable high and low setpoint limit values to
restrict the setting range of the setpoint. Set the limit values so that the
temperature setpoint value cannot be set outside the safe operating area of
the process.
SPLO - -999 to 9999
SPHI - -999 to 9999
