Positioning of the product

The product must be positioned in a way that does not make it difficult to operate disconnector devices.
The product must be installed in an indoor environment.

Mounting on DIN rail

The product must be installed on a 35mm DIN rail fixed in an electrical panel.
Be careful to lock the housing on the DIN rail.

The DIN rail mount consists of 2 parts: a base and a movable and adjustable latch.
It is used to fix the Tyness horizontally or vertically on a DIN rail.

The product can be removed from the DIN rail by manipulating the movable latch with a screwdriver like any other bracket of the same type.

Installation

Before starting the installation of the SQUID Pro, ensure that you use a 5VDC – 2A power supply positioned at the head to power the device. It is important to maintain and separate the wiring of Low Voltage Safety Circuits (TBTS) from the circuits under dangerous voltage to ensure safety and proper system operation.

When wiring, make sure to observe the polarity of the power connector of the SQUID Pro.

The connection of the measurement clamps to the SQUID Pro is simplified using a quick connector, eliminating the need for tools. Connect the measurement probes to the 12 connectors located on the top and bottom of the device. Make sure not to exceed the maximum current specification for each measurement clamp to avoid the risk of damage or overheating.

To ensure safety during the installation of the clamps, it is imperative to perform this operation when the circuit is de-energized. Use exclusively Ewattch measurement clamps with the reference CURCLAMP-HC-SX, specially designed for optimal compatibility with the SQUID Pro.

The current measurement clamps of the SQUID Pro have a specific orientation, which must be respected. The clamps must be installed so that the arrow on the clamp points towards the energy consumer.

By following these installation and implementation recommendations, you will ensure safe and efficient operation of your SQUID Pro electrical sub-metering system.

There are 2 possible wiring modes with the SQUID Pro:

• Three-phase mode, allowing the measurement of 4 three-phase circuits.

Caution: It is necessary to follow the indications presented in diagram 1 for the wiring.

• Single-phase mode, allowing the measurement of 12 single-phase circuits.

Caution: It is necessary to follow the indications presented in diagram 2 for the wiring.

The software allows you to configure the desired types of measurements, transmission intervals, LoRa communication, and many other options with just a few clicks.

Furthermore, you benefit from firmware update support, ensuring that your device stays up to date with the latest improvements and features. With the SQUID Pro Rogowski configuration software, you have complete control over your sub-metering system, guaranteeing accurate monitoring and continuous optimization of your energy consumption.

Software Description

Energy menu

In this menu you can:

• Read the different measurements taken by the Squid pro. This will allow you to simply validate the correct installation of the product.
• Configure the interval between 2 radio transmissions.
• Select the measurements that will be transmitted.
  • The energy drop-down menu allows you to choose which energies will be transmitted among the following: Active positive and negative, reactive positive and negative and apparent. These are the energy accumulations measured by the Squid pro.
  • The power menu allows you to configure the Squid pro to transmit in addition to energy measurements, power measurements of your choice.
  • The voltage menu allows you to configure the Squid pro to transmit its voltage measurements.
  • The Frequency menu allows you to configure the Squid pro to transmit its frequency measurements.
  • The Tri Phase button activates the aggregation of the measurements of the 12 individual phases into only 4 three-phase measurements. This option simplifies the processing of measurements.
  • The IRMS button allows you to configure the Squid pro to transmit its current measurements.

Radio Menu

In this menu you can:

• Choose between configuring the Squid pro in LoRaWan mode or LoRa Ewattch mode. In LoRaWan mode, the product will be compatible with all LoRaWan solutions, in LoRaEwattch mode, the Squid will be able to communicate with Tyness 4G and Ewattch toolbox products.

LoRaWan mode

• It will be possible to configure the data rate of the product. In ADR configuration, the data rate will be automatically configured by the network. The data rate can also be set among six levels depending on usage. DR0 rate is the slowest rate that will maximize range.
• You can activate or deactivate periodic joining. This function allows you to force the Squid pro to reconnect to the LoRaWan network once a week.
• Customization of APPEUI and APPKEY is available in this menu.
• The conformity test mode is only to be used in the LoRaWan laboratory.
• The message confirm mode allows you to configure the Squid pro to retransmit its message if it has not been received by the network. Please note, only activate this option if the radio performance is good. This option helps prevent the loss of a message from time to time but is not intended to compensate for poor radio coverage.

LoRaEwattch mode

• The menu allows you to configure the SquidPro transmission channel. For communication to be established correctly with Tyness 4G and/or toolbox products, the two products must be configured on the same channel.
  The short channels will accommodate more products which will communicate more often and the long range channels a maximum of 20 products but at maximum range.
• The power adjustment allows you to modify the transmission power of the Squid pro. 14dbm being the maximum power.

Update menu

This menu allows updating the Squid pro. The update file is available on the following page.

The Squid Pro transmits its data in a raw format over various LoRaWAN public and private networks. The section below shows you how to decode the frames (payloads) sent by the Squid Pro.

Periodic Frames

Periodic frames contain the data measured by the Squid Pro.

Example of a transmitted periodic frame (HEX format):

Tip – Rollover Management

To facilitate the management of energy measurement rollovers, the most significant bit of these measurements is used to indicate if a rollover has already occurred. It is never reset to 0. Therefore, during a rollover, the measurement will transition from 0xFFFFFF to 0x800000.

Tip – LoRaWAN Payload Decoding

To facilitate the integration of products communicating via the LoRaWAN network, Ewattch has developed a payload decoder available at this address: https://ewattch-documentation.com/?page_id=2215.
