### Analog Output 4-20mA Parameter Configuration

Follow the steps below to configure analog output parameters:

{% stepper %}
{% step %}

#### **Set Basic Parameters**

* Refer to the [**Parameter Settings**](broken://pages/4666519d0a0ec96357603936c826afa0b4814a3f) 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.
  {% endstep %}
  {% endstepper %}

{% hint style="info" %}
After completing the 4–20 mA settings, verify the configuration using **Simulation Mode** to ensure correctness.
{% endhint %}

## **SPEC**

### **Analog output (4-20mA)**

## **Cable** wiring

Please see the page of [Electrical installation.](/qr/fp-as310-english-v5/installation-and-setup/electronic-installation.md)

## **Parameter setup**

Please refer to the [parameter set-up page.](/qr/fp-as310-english-v5/parameters.md)

Set-up steps as below:

1. Please set up the [basic parameters](/qr/fp-as310-english-v5/installation-and-setup/parameter-setup.md) first.
2. Connect cable first according to the cable wiring instructions on this page.
3. Set up parameter E06 for opening Analog current output function, and select the data content to be output.
4. The current range to be set up by using parameter E13 is 4-20mA.
5. Parameter E07 and E08 are for specifying maximum and minimum value to output. These 2 values can be either positive or negative, however, E07 has to be smaller than E08.
6. Use E09 to set output current milliamps when output data is out of the E07 and E08 range.
7. Please enter the E11 parameter page to test and adjust 0mA/ 4mA output current. Adjustment unit is uA.
8. Please enter the E12 parameter page to test and adjust 20mA output current. Adjustment unit is uA..
9. If the output current is too low and can not reach 20mA after modifying parameter E12, please check the 4-20mA specification on the [main screen page](/qr/fp-as310-english-v5/user-interface/monitor-page-explanation.md) for line impedance and supply voltage requirement.
10. Use parameter F01 for setting up the flow volume value to be simulated. Turn on F02 and go back to the monitoring screen.
11. Confirm that the external device receives the signal correctly.
12. Turn off F02 and go back to the monitoring screen.
13. Finish.
