Installation Overview

This page will cover the process that can be followed to integrate a Captis Multi with a Bermad MC406 via Modbus.

A detailed step-by-step can be found in subsequent sections of this guide. A more concise outline of the installation is as follows:

Connect Captis wiring to MC406 headers
Enable MC406 Modbus communications, verify DAS communication
Adjust the MC406 Modbus activation window to match Captis
Verify DAS communication prior to finalising install on DQP Portal

MC406 Wiring

1.1 Pulse Wiring

1.1 (a) Pass Captis Wires Through Gland

Strip back and pass the following cores through the MC406 cable gland:

White
Black
Blue
Red

1.1 (b) Terminate Wires To the Two Positive or Negative Terminations

Ensure you connect the white and black wires to the same loop - generally 1 & 2 for positive and 3 & 4 for negative. Positive indicates forward flow and negative indicated a reverse direction of flow.

1.2 Modbus Wiring

1.2 (a) Pass Captis Wires Through Gland

Strip back and pass the following cores through the MC406 cable gland

Black
Yellow
Orange
Blue
White

1.2 (b) Terminate Connections

Remove the connector (circled red) and terminate the Captis connection as below

MC406 GND > Captis Black
MC406 B > Captis Yellow
MC406 A > Captis Orange

Inside the MC406, securely terminate the Captis cable cut detection. Ensure sufficient insulation to prevent risk of short circuits. Solder and heat shrink or boot-lace ferrules are recommended.

Captis Blue > Captis White

1.2 (c) Close MC406

Connect terminated MC406 modbus connector to PCB, ensure cable cut leads are securely connected and insulated, reinstall required MC406 components (e.g battery) and close converter.

2. Test DAS Communication

Due to the extensive battery saving features of the MC406, it is necessary to follow the below process to ensure converter battery life and reliable RTU communication.

2.1 Enable MC406 Modbus Output

For assistance navigating the on screen converter menu, please refer to the MC406 manual attached at the bottom of this page.

Using the navigation buttons, access the device function settings and change F46 to a value of 12

2.2 Wake Captis

Using the included magnet, wake up the Captis by touching it to the 'Wake' engraving.
Wait for the Captis light to come on, and then turn off (approx. 2 minutes)

2.3 Verify DAS Flow

Using a Laptop, Tablet, or Phone log in to the WaterNSW DAS via https://app.eagle.io/login
On the left side bar, identify the correct site and click on it.
Press 'Dash' in the top right
Inspect Dashboard for flow total and compare to MC406 display

If you're having issues accessing or using the DAS, feel free to give SigSense a call (07 3053 5229) and we'll help you verify the DAS reading.

Once the DAS reading has been confirmed, DO NOT WAKE THE CAPTIS AGAIN, CHANGE THE WIRING OR INTERFERE WITH THE CABLE CUT.

3. Adjust MC406 Modbus Activation (Battery Powered Only)

In step 2 we permanently enabled the modbus output of the meter to allow for the LID, meter and DAS to be tested 'end-to-end'. To permit greater battery life where no external power (e.g DC / Solar) is available, we must now change the Modbus activation window of the MC406 to match and sync with the installed Captis.

Once changed, the MC406 will keep the modbus interface active until it receives a Modbus request. The MC406 will then disable the modbus output and begin enabling it on the interval defined by the setting, F46. As a result, it is important the next measurement request be the hourly scheduled measurement from the LID. Do not wake the device, interfere with the cable cut or disconnect the cable once beginning this section as it will result in the Captis measurement and MC406 activation intervals being out of sync.

Currently, all Captis devices used in NSW Non-urban metering have 60 minute logging intervals (on the top of each hour). This requires a setting of F46 = 11.

For assistance navigating the on screen converter menu or converter setting details, please refer to the MC406 manual attached at the bottom of this page.

3.1 Adjust MC406 Modbus Interval

For assistance navigating the on screen converts menu, please refer to the MC406 manual attached at the bottom of this page.

Using the navigation buttons, access the device function settings and change F46 to a value of 11.

Do not wake the device, interfere with the cable cut or disconnect the cable after completing this section.

4. Post installation DAS Verification

Although communication was verified in step 2, SigSense recommend a further check of the DAS at least 1 day after installation to ensure the MC406 activation window has been correctly set and measurements are successful.

4.1 Final DAS Verification

Using a Laptop, Tablet, or Phone log in to the WaterNSW DAS via https://app.eagle.io/login
On the left side bar, identify the correct site and click on it.
Press 'Dash' in the top right
Inspect Dashboard for flow total and ensure hourly measurements are successful

If you're having issues accessing or using the DAS, feel free to call (07 3053 5229) and we'll help you verify the DAS reading.
