## 4–20 mA Analog Output Wiring Diagram

* **Brown:** 24 VDC (+), **Blue:** 0 VDC (–), **Purple:** 4–20 mA Output (+)

This function operates only when the brown and blue lines are powered by a DC supply.

### Analog Output 4-20mA Parameter Configuration

Follow the steps below to configure NPN output parameters:

{% stepper %}
{% step %}

### **Set Basic Parameters**

* Refer to the [**Parameter Settings**](https://docs.lorric.com/qr/fu-lt-english-v1/installation-and-setup/parameter-settings) page and complete the following steps: **Language Setting, Pipe Settings:A02:** Pipe Standard, **A04:** Pipe Outer Diameter, **A06:** Pipe Wall Thickness, **A08:** Pipe Material
* Execute **Z03 (Automatic Initialization)**.
  {% endstep %}

{% step %}

### **Wiring Setup**

Connect the 4–20 mA analog output wiring according to the instructions on this page.
{% endstep %}

{% step %}

### **E06 Analog Output Content (Select Output Data Type)**

Set parameter **E06 Iout Def.** to enable the analog current output and select the data to be output. Available options: **“Cumulative Total”**, **“Flow Rate”**, or **“Flow”**.
{% endstep %}

{% step %}

### **E13 – Analog Output Range (Set Current Range)**

Use parameter **E13 Iout Range** to set the current output range to **4–20 mA**.
{% endstep %}

{% step %}

### E07 – 4 mA Value / E08 – 20 mA Value (Set Output Minimum and Maximum)

Set parameters **E07 4mA Value** and **E08 20mA Value** to define the output minimum and maximum. Negative values are allowed. **Note:** E07 must be less than E08.

* **Example:** To map 4–20 mA to a range of **−10 to +20**:
  * Set **E07 (4 mA Value)** to **−10**
  * Set **E08 (20 mA Value)** to **+20**

Intermediate values are calculated linearly: 12 mA ≈ **+5,** 16 mA ≈ **+15**
{% endstep %}

{% step %}

### E09 **Analog Error Value (Set Output for Out-of-Range Flow)**

Use parameter **E09 Iout Error** to specify the current output when the flow value exceeds the range defined by **E07** and **E08**.

* Example: **E09 mode:** 2.4 mA & 21.6 mA, **E07:** −10, **E08:** +20
  * Flow < E07 (−10) → output **2.4 mA**
  * Flow > E08 (+20) → output **21.6 mA**
    {% endstep %}

{% step %}

### E11 4 mA Fine Adjustment (µA) (Adjust 4 mA Output)

Enter **E11 4mA Fine Adj. µA** to test and adjust the 4 mA output. Each increment or decrement of 1 changes the output current by 1 µA.

* If an external ammeter measures 3.95 mA, which is 0.05 mA (50 µA) below the target of 4.00 mA,
* Set E11 to +50. The output will then be corrected to 4.00 mA.
  {% endstep %}

{% step %}

### E12 20 mA Fine Adjustment (µA) (Adjust 20 mA Output)

Enter **E12 20mA Fine Adj. µA** to test and adjust the 20 mA output. Each increment or decrement of 1 changes the output current by **1 µA**.

* If an external ammeter measures **19.95 mA**, which is **0.05 mA (50 µA)** below the target of **20.00 mA**, set **E12** to **+50**. The output will then be corrected to **20.00 mA**.
* If the 20 mA output cannot reach the target after adjusting **E12**, this may be due to excessive loop impedance or insufficient voltage. Check the **4–20 mA specifications** on the Motor Installation page and adjust the loop impedance or increase the voltage as necessary.
