1. Select OUTPUT 1 or 2
SELECT SOURCE
Press ENTER to access a list of all connected sensors. Choose the sensor to associate with the output.
SET PARAMETER
Highlight the appropriate displayed parameter and press ENTER
.
SET FUNCTION
Select LINEAR CONTROL for current output to track the measurement value. Select PID CONTROL for the sc100 to operate as
a PID controller.
SET TRANSFER
Each analog output is normally active, responding to the measured value of its assigned parameter. However, during calibration,
each output can be transferred to this preset transfer value. Default: 4mA; Range: 0–20
SET FILTER
Allows the user to average the analog outputs over time Default: 0; Range: 0–120 seconds
SCALE 0 mA/4 mA
Select 0 mA or 4 mA for minimum current (outputs will be set to 0–20 mA or 4–20 mA).
ACTIVATION
FUNCTION set to LINEAR CONTROL
If LINEAR CONTROL was selected in SET FUNCTION, set the low and the high values for the current output here.
Defaults: Low = 0; High = 100; Low Value Range: 0–100, High Value Range: 0–100.
FUNCTION set to PID CONTROL
If PID CONTROL was selected in SET FUNCTION, configure the PID Control as follows:
1. Set MODE: AUTO or MANUAL. Manual output default: 100%
2. Set PHASE: DIRECT or REVERSE controller operation.
3. SET SETPOINT: enter the set point the PID control will control the process to. Default: 100; Range: 0–100
4. PROP BAND: control the proportional band for the PID control. Default: 5.00; Range: 0–1000
5. INTEGRAL: control the integral action time period in minutes. Range: 0–999
6. DERIVATIVE: control the settings for the rate control. Range: 0–999
