1 Introduction

1.1 Description and function of the EcoPhi Basic Controller

The EcoPhi Basic Controller is a modern communication edge device that has been specially developed for the requirements of renewable energy systems. The device enables the monitoring and simple control of serial devices, sensors and actuators and provides a central platform for data processing.

The Basic Controller was developed by EcoPhi, a company specializing in innovative IoT solutions for renewable energy. EcoPhi focuses on providing efficient and robust technologies that enable customers to optimally operate and monitor their systems. The Basic Controller plays an important part in this offering, as it ensures reliable data collection and a stable connection to the EcoPhi Cloud.

The EcoPhi Basic Controller is a central component of modern energy systems that combines several essential functions. It was developed to collect data from connected external devices and sensors, process it locally and make it accessible via a cloud platform. The Basic Controller is mainly used to collect data, but can also to be used for simple control functions.

1.2 Safety instructions

The installation and operation of the EcoPhi Basic Controller requires compliance with basic safety regulations to ensure the safety of persons and equipment:

Installation by qualified personnel: The Basic Controller may only be installed and maintained by qualified specialist personnel in order to avoid risks such as electric shocks or malfunctions.

Switch off the power supply: Before installation or maintenance, ensure that the power supply to the device is disconnected.

Use the components supplied: Only use the parts recommended or supplied by EcoPhi to ensure functionality and safety.

Seal cable glands: Open cable glands must be properly sealed before commissioning to prevent the ingress of moisture or foreign bodies.

Notes on correct cabling and proper connections

Note

Approximately 80% of all problems in connection with the installation of the EcoPhi Basic Controller are caused by incorrect cabling and connections.

• It is strongly recommended to use shielded cables.
• Ensure that there are no sources of interference near the cables, e.g. motor cables, power cables, high-power cables.
• The greater the distances, the greater the influence of possible sources of interference
• Connect cables properly and not via loose plug contacts or simple insulating tape.
• If necessary, remove the supplied terminals from sensors supplied by EcoPhi, as they are not intended for permanent use, but only to show that the wiring is correct.
• If necessary, use the heat-shrink tubing supplied to extend and connect the cables.

For serial devices: Avoid star connections; the maximum distance for star connections is 100 m. A 120 Ohm resistor at the end of the connections improves transmission.

For pulse sensors: Avoid magnetic interference fields in the vicinity of pulse sensors, e.g. door sensors or water meters.

1.4 Technical data

1.4.1 Power consumption

Under maximum load, the Basic Controller can consume up to 30 watts. This maximum power consumption typically occurs during intensive use, for example when numerous devices are connected or when a high data transfer rate is required.

In normal operation, however, the average power consumption of the Basic Controller is around 3 to 4 watts. This value varies depending on the number and type of sensors connected, the frequency of data transmission and the communication interfaces used, such as WiFi or Ethernet. The use of the integrated touchscreen can also increase power consumption.

The low average power consumption of the Basic Controller also makes it suitable for applications in energy-efficient systems, where minimizing power consumption is of central importance.

The EcoPhi Basic Controller requires a reliable power supply for operation, which is provided via 230V AC as standard. The incoming AC voltage is converted into 24V DC via an integrated AC/DC converter, which supplies the Basic Controller and the connected devices with energy.

Maximum power consumption: The Basic Controller has a maximum power consumption of 1.25A under full load, depending on the number and type of sensors and outputs connected. In normal operation, consumption is significantly lower, meaning that the device works efficiently and economically.

Emergency power supply: The Basic Controller is equipped with an internal battery that keeps the data logger operational for up to 4-5 hours even in the event of a power failure. This backup power solution ensures that important data continues to be stored and that there is no interruption in communication with the platform as soon as the main power supply is restored.

Alternative power supply: It is also possible to use your own or an alternative power supply. However, this must be compatible with the connected devices and be able to supply a voltage between 11.5V and 30V DC. Stable operation of the Basic Controller is only guaranteed if these specifications are met. A minimum supply of 14 VDC is required for the configuration of the 0-10 V analog output.

1.4.2 Data consumption

The data consumption of the EcoPhi Basic Controller depends largely on the connected devices, the frequency of data transfers and the quality of the internet connection. While a stable connection reduces consumption, unstable connections can lead to higher data consumption due to repeated or repeated connection attempts.

In a typical system comprising a moderate number of sensors and devices, the average monthly data consumption is around 200 MB. However, this value can vary considerably. Systems with a higher number of sensors or more frequent transmission intervals require correspondingly more data volume. Conversely, consumption can be reduced for systems with fewer data points or longer transmission intervals.

The Basic Controller is therefore designed to keep data consumption efficient by only transmitting relevant data and minimizing unnecessary repetitions. This also makes it suitable for systems that rely on mobile connections with limited data volumes.

4 Error messages

This chapter describes how you can proceed in the event of errors or problems with the EcoPhi Basic Controller in order to identify and, if necessary, rectify the causes.

LEDs flash red quickly

If all the Basic Controller LEDs flash red quickly, this indicates a hard fault in the software. This is a critical error that puts the device out of operation. In such cases, the following steps should be taken:

Restart the device: Press the Restart button to reset the device. In many cases, this will temporarily rectify the error so that a new connection to the platform can be established.

Contact support: If the error persists, contact EcoPhi Support. Make a note of the exact time of the error and all observed symptoms to enable a quick diagnosis.

Touch screen no longer responds and LEDs S1 and S2 flash monotonously or are off

This behavior indicates a serious internal fault, which is usually caused by GND faults in connected devices. Poor earthing can result in voltage differences between the EcoPhi Basic Controller and the connected devices (e.g. via RS485 or Ethernet) having to be reduced. This can cause internal damage to the Basic Controller. In such cases, the following steps should be taken:

Contact EcoPhi Support: Disconnect the device from the power supply and the connected devices and report the problem to EcoPhi Support. Describe the connected devices and the cabling in order to narrow down the cause of the problem.

Check earthing: Ensure that all connected devices are properly earthed. Poor earthing can lead to voltage differences that are equalized via the communication lines (e.g. RS485 or Ethernet) and can therefore cause damage.

Note

Prevention: Use earthing cables and ensure that all devices have a common earth potential to avoid this type of fault.

Sensor or externally connected device is not responsive

If a connected sensor or external device does not respond or does not provide any data, proceed as follows:

1. check cable connections: Check that all cables are correctly and firmly connected to the corresponding pins. Also check whether there is any visible damage to the cables, such as breaks or corrosion.

2. check the status on the display: For analog and digital sensors: The status of these sensors is shown live on the Basic Controller display. A signal displayed as “On” or “Off” (for digital sensors) or as a bar (for analog sensors) indicates that the device is correctly wired. If no signal is visible, there may be a wiring error or a defective sensor.

3. check serial connections: RS485 or RS232 connections cannot be checked directly via the display. These connections are diagnosed via the cloud or a debugger on site.

4. RS485 device does not respond: If an RS485 device does not respond to commands, carry out the following steps:

Check Modbus ID: Ensure that the Modbus ID of the connected device is configured correctly.

Check the wiring: Check that cables A and B are connected correctly and are not reversed. Incorrect polarity means that no data can be transmitted.

Termination: Check whether a termination resistor (typically 120 Ohm) has been inserted at the end of the RS485 line. Signal interference can occur without this resistor.

Signal interference: Ensure that the RS485 cable is not routed near high-voltage lines or other sources of electromagnetic interference.

Debugging: Use a debugging tool or a protocol analyzer to check the data traffic on the RS485 line. This can help to identify communication problems.

5. settings in the platform: Check in the platform whether the settings for the corresponding sensor are correct (e.g. readout frequency, Modbus port or Modbus TCP port).

If the platform shows the connection to the sensor but the data does not appear correctly, the problem may be with the sensor itself.
