4 Overview This manual documents the ACX104_Sensor function block. The ACX104_Sensor function block scales the voltage input from a Danfoss ACX104 Potentiometer Rotary Position Sensor into percent and scaler (degree) outputs that indicate rotary position. The ACX104_Sensor function block works with ACX104 Sensors that receive a calibrated supply voltage of 5.0 V DC (±0.1) from PLUS+1 controllers. See About Function Block Connections on page 6 for an overview of this function block s connections and signals. Inputs Inputs Input Type Range Description Para Bus Brings external inputs (such as digital inputs) into the function block. See About the Para Input on page 20 for more about this input. Sensor 0 to 5000 Inputs voltage from the ACX104 sensor. The position of the sensor varies this voltage = 1000 mv. L Rev CA July

8 Setup Page Calibration Settings The Setup page contains values that configure how you calibrate this function block. You can calibrate the function block three ways: Default calibration you apply preset calibration values to the function block. These are fixed values. You cannot change them. Auto-calibration as you move the sensor through its operating range, the function block captures sensor input voltages that fall within acceptable voltage ranges. Manual calibration you apply your own calibration values to the function block. These values must fall within defined voltage ranges to be valid. 8 L Rev CA July 2015

9 Setup Page Calibration Settings Input Type Range Description Set_Defaults BOOL A false-to-true transition writes default calibration values into memory (EE). Calibration values define the profile that the function block applies when converting a Sensor input voltage into Percent and Scaler outputs. When the Set_Defaults signal transitions from false to true, the function block writes a default calibration value of: 3750 to the EE_Voltage_High memory location. This is the high calibration value. With this value, a Sensor input of 3750 mv produces a Percent output of (100.00%) and a Scaler output of ( ) to the EE_Voltage_Mid memory location. This is the middle calibration value. With this value, a Sensor input of 2500 mv produces a Percent output of 0 (0.00%) and a Scaler output of 0 (0.000 ) to the EE_Voltage_Low memory location. This is the low calibration value. With this value, a Sensor input of 1250 mv produces a Percent output of ( %) and a Scaler output of ( ). (The Scaler outputs assume that the Setup page has Scaler_Max and Scaler_Min parameter values of and ) F to EE_Phase memory location. This is the default phase value. With this value, the polarity of the Percent and Scaler outputs stays unswitched. Positive outputs stay positive. Negative outputs stay negative. L Rev CA July

10 Auto_Calibrate BOOL A false-to-true transition starts an auto-calibration procedure that writes high, middle, and low calibration values into memory (EE) as the Sensor input voltage moves through its operating range. Calibration values define the profile that the function block applies in converting a Sensor input voltage into Percent and Scaler outputs. When the Auto_Calibrate signal transitions from false to true, the function block writes a Sensor input voltage that ranges between: mv to the EE_Voltage_High memory location. This is the high calibration value. A Sensor input voltage that is equal to the EE_Voltage_High value produces a Percent output of (100.00%) and a Scaler output of ( ). The Cal_Midpoint_Max and the Cal_Midpoint_Min values to the EE_Voltage_Mid memory location. This is the middle calibration value. A Sensor input voltage that is equal to the EE_Voltage_Mid value produces a Percent output of 0 (0.00%) and a Scaler output of 0 (0.000 ) mv to the EE_Voltage_Low memory location. This is the low calibration value. A Sensor input voltage that is equal to the EE_Voltage_Low value produces a Percent output of ( %) and a Scaler output of ( ). (The Scaler outputs assume that the Setup page has Scaler_Max and Scaler_Min parameter values of and ) The block only writes a Sensor value into memory if it falls within a valid range and stays within this range for more than three seconds. Cal_Center_Only BOOL F = The auto-calibration procedure captures the high, middle, and low calibration values. T = The auto-calibration procedure captures only the middle calibration value. Cal_Midpoint_Max U to 3125 Cal_Midpoint_Min U to 3125 Input_Limit_High U to 4000 Sets the upper limit of the valid range for middle calibration values. The Cal_Midpoint_Max value applies in auto-calibration and manual calibration procedures. The Cal_Midpoint_Max value must be greater than the Cal_Midpoint_Min value = 1000 mv. Sets the lower limit of the valid range for middle calibration values. The Cal_Midpoint_Min value applies in auto-calibration and manual calibration procedures. The Cal_Midpoint_Min value must be less than the Cal_Midpoint_Max value = 1000 mv. The function block outputs an Input value too high fault when the Sensor input voltage rises above this value. The Input_Limit_High value must be greater than the Input_Limit_Low value = 1000 mv. 10 L Rev CA July 2015

11 Input_Limit_Low U to 4000 Val_Voltage_High U to 4000 Val_Voltage_Mid U to 3125 Val_Voltage_Low U to 1500 The function block outputs an Input value too low fault when the Sensor input voltage falls below this value. The Input_Limit_Low value must be less than the Input_Limit_High value = 1000 mv. This value applies in a manual calibration procedure. A false-to-true transition of the Set_Voltage_High signal writes this value into the EE_Voltage_High memory location as the high calibration value. Calibration values define the profile that the function block applies in converting a Sensor input voltage into Percent and Scaler outputs. A Sensor voltage that is equal to the EE_Voltage_High value produces a Percent output of (100.00%) and a Scaler output of ( ). (The Scaler output assumes that the Setup page has Scaler_Max parameter value of ) 1000 = 1000 mv. This value applies in a manual calibration procedure. A false-to-true transition of the Set_Voltage_Mid signal writes this value into the EE_Voltage_Mid memory location as the middle calibration value. Calibration values define the profile that the function block applies in converting a Sensor input voltage into Percent output and Scaler outputs. A Sensor input voltage that is equal to the EE_Voltage_Mid value produces a Percent output of 0 (0.00%) and a Scaler output of 0 (0.000 ) = 1000 mv. This value applies in a manual calibration procedure. A false-to-true transition of the Set_Voltage_Low signal writes this value into the EE_Voltage_Low memory location as the low calibration value. Calibration values define the profile that the function block applies in converting a Sensor input voltage into Percent and Scaler outputs. A Sensor input voltage that is equal to the EE_Voltage_Low value produces a Percent output of ( %) and a Scaler output of ( ). (The Scaler output assumes that the Setup page has Scaler_Min parameter value of ) 1000 = 1000 mv. Val_Phase BOOL You can apply this value in a manual calibration procedure. A false-to-true transition of the Set_Phase signal writes this value into the EE_Phase memory location as the phase value. The EE_Phase value sets the polarity of the function block s Percent and Scaler outputs. Changing the Val_Phase value makes positive values negative and negative values positive. L Rev CA July

12 Set_Voltage_High BOOL You transition this signal in a manual calibration procedure. A false-to-true transition of this signal writes the Val_Voltage_High value to the EE_Voltage_High memory location. The EE_Voltage_High value is the high calibration value. Set_Voltage_Mid BOOL You transition this signal in a manual calibration procedure. A false-to-true transition of this signal writes the Val_Voltage_Mid value to the EE_Voltage_Mid memory location. The EE_Voltage_Mid value is the middle calibration value. Set_Voltage_Low BOOL You transition this signal in a manual calibration procedure. A false-to-true transition of this signal writes the Val_Voltage_Low value to the EE_Voltage_Low memory location. The EE_Voltage_Low value is the low calibration value. Set_Phase BOOL You can transition this signal in a manual calibration procedure. A false-to-true transition of this signal writes the Val_Phase value to the EE_Phase memory location. The EE_Phase value sets the phase (polarity) of the function block s Percent and Scaler outputs. Scaler_Max S16 ±32767 Sets the maximum positive Scaler (degree) output. Typically, this value should represent the most positive rotation of the ACX104 Sensor = Scaler_Min S16 ±32767 Sets the maximum negative Scaler (degree) output. Typically, this value should represent the most negative rotation of the ACX104 Sensor = Chkpt BOOL T includes the function block s built-in Advanced Checkpoint with Namespace components when you compile the LHX download file. The Service Tool program will be able to access function block signals through these checkpoints. F excludes the function block s built-in Advanced Checkpoint with Namespace components when you compile the LHX download file. The Service Tool program will not be able to access function block signals through these checkpoints. 12 L Rev CA July 2015

13 About Default Calibration Values This graph shows how the default calibration values configure the relationship between the function block s Sensor input voltage and its Percent and Scaler outputs. Default calibration you apply preset calibration values to the function block. These are fixed values. L Rev CA July

14 About Auto-Calibration Ranges In an auto-calibration procedure, the function block captures high, middle, and low calibration values as the block s Sensor input voltage moves through its operating range. The block only captures sensor voltages that fall within specific ranges and stay within these ranges for more than three seconds. This graph shows the ranges in which the function block can capture low, middle, and high calibration values in an auto-calibration procedure. In an auto-calibration procedure, the: Default low calibration value of 1250 (±250) mv sets the range for a valid low calibration value. A valid low calibration value must fall between 1000 and 1500 mv. Default high calibration value of 3750 (±250) mv sets the range for a valid high calibration value. A valid high calibration value must fall between 3500 and 4000 mv. Cal_Midpoint_Max value and the Cal_Midpoint_Min values set the range for a valid middle calibration value. 14 L Rev CA July 2015

About the Name Space Value If you use the same function block more than once in an application, you must change each function block s Name Space value to avoid compiler errors.

22 About the Name Space Value If you use the same function block more than once in an application, you must change each function block s Name Space value to avoid compiler errors. These function blocks allocate memory and checkpoints using names ( aliases ). Identical function blocks have identical memory and checkpoint names. Identical memory and checkpoint names will cause a compiler error. The Name Space value adds a unique prefix to each memory and checkpoint name to avoid errors. Keep Name Space values short to save controller memory. How to Enter a Name Space Value In the PLUS+1 GUIDE menu bar, click the Query/Change button. 4. Click the function block s page name to display the Edit Page window. 5. In the Edit Page window, enter a meaningful Name Space value. 6. Press /. 7.
