Display Values (Dsp1 & Dsp2); Signal Input Values (Inp1 & Inp2); Setpoint Limit Values (Splo & Sphi); Setpoint Ramp Rate (Sprp) - Omega CN63100 Series User Manual

Before programming the indicator, it is advised to organize all the data for
the programming steps to avoid possible confusion.
To scale the indicator, two signal values and two display values that
correspond to the signal values must be known. These four values are used to
complete the scaling operation. An example is listed below:
Scaling Point #1
0.0% @ 4.00 mA & 100.0% @ 20.00 mA
Reverse acting indication can be accomplished by either reversing the two
signal points or the display value points, but not both. If both are reversed,
then forward (normal) acting indication will occur. In either case, do not
reverse the input wires to correct the action.
Display Values (dSP1 & dSP2)
Key-in the display value for scaling point one and scaling point two.
dSP1 -999 to 9999
dSP2 -999 to 9999
Signal Input Values (INP1 & INP2)
The signal input value can either be keyed in via the front panel buttons or
an input signal can be applied to the appropriate signal input terminals. When
entering the signal input parameter, the unit is in the key-in mode.
Key-in Method
Key-in the signal value for scaling point one and scaling point two.
INP1 -999 to 9999
INP2 -999 to 9999
Signal Input Method
To change to the apply signal method press the D button. Front panel
annunciators %P and DV will flash, and the display indicates the signal value
applied to the input terminals. The unit can be toggled to the key-in method by
pressing the D button again.
Signal Range
4.00 to 20.0 mA DC
0.00 to 10.00 VDC
When the desired value is indicated on the display, press the P button to
store the value and advance to the next parameter.
Scaling Point #2
(Ex. 0.0%)
(Ex. 100.0%)
(Ex. 0.00 VDC or 4.00 mA DC)
(Ex. 10.00 VDC or 20.00 mA DC)
Display Range
0.00 to 20.00
0.00 to 10.00
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
setpoint value cannot be set outside the safe operating area of the process. On
models equipped with Second Analog Input, configured as a Remote
Setpoint, the Remote Setpoint reading is also restricted to these limits.
SPLO - -999 to 9999
SPHI - -999 to 9999

Setpoint Ramp Rate (SPrP)

The setpoint can be programmed to ramp independent of the controller's
decimal point position and rounding increment. The setpoint ramp rate can
reduce sudden shock to the process, reduce overshoot on start-up or setpoint
changes, or ramp the process at a controlled rate.
SPrP - 1 to 9999 units/minute
Note: Defined here, a unit is the LSD of the display, regardless of decimal point
position.
A ramp value of zero disables setpoint ramping. If the optional user input is
programmed for setpoint ramp, it affects the enabling and disabling of
setpoint ramping. Setpoint ramping is initiated on power-up or when the
setpoint value is changed. Active Setpoint Ramping is indicated by the left
most decimal point flashing in the main display.
