Frequently Asked Questions - ESY I/O DAB

How to install the ESY I/O module?

Installation must be carried out by qualified personnel. Fix the rear panel to the wall after drilling holes and inserting wall plugs, then make the electrical connections (100-240 VAC power supply) and input/output connections according to the diagram. Close the front panel by tightening the 4 screws.

How to connect ESY I/O to the DConnect app?

Download the DConnect app (Smart Solution). Use Bluetooth or WiFi connection in point-to-point mode. In the app, select the Esy I/O product and follow the instructions for direct connection.

How to reset the proprietary wireless configuration?

Press the 'Wireless' touch button for 5 seconds until the blue LED flashes and then turns off. The network configuration is then cleared.

What do the different LEDs on the interface mean?

Power LED is white; Error LED is flashing red; Pressure LED is green; Modbus LED is green/red; Internet LED is blue (RFU); Bluetooth LED is blue; the 4 input LEDs are green; the 4 output LEDs are yellow; DAB wireless LED is blue; WiFi LED is blue. See table 1 of the manual for details.

What to do if the power LED remains off?

Check the power wiring (100-240 VAC, min. 0.8 mm² cross-section) and check for short circuits. If the problem persists, cut the power and inspect the connections.

Can I use a pressure sensor other than the HUBA 0-25 bar model?

Currently, only the HUBA 0-25 bar pressure sensor is supported. The selection is made via the DConnect app. Use of other sensors is not guaranteed.

How to configure Modbus communication?

Via the DConnect app, enable Modbus mode and set the baud rate (2400 to 115200), parity (None, Even, Odd), number of stop bits (1 or 2), response delay (0-1000 ms), and slave ID (1-247). The RS485 wiring must be correct (terminals A, B, GND).

What is the maximum number of devices on the Modbus bus?

It is recommended not to exceed 32 devices on the RS485 bus. A termination resistor (120 ohms) may be required on the first and last device.

How to update the module firmware?

Use the DConnect app to check and install updates. The update may take up to 5 minutes and the device will restart automatically. Ensure the power supply is stable during the operation.

What to do in case of 'insufficient supply voltage' error (error LED flashes once)?

Check for possible overloads due to wiring of sensors, inputs, and outputs. Reduce the load or check the power supply. If the problem persists, contact technical support.

Table 1: Led Description

Esy I/O has two touch buttons in the interface (Wireless and wifi). When the touch button is pressed, the corresponding LED blinks rapidly. The implementation of the commands, described below, is confirmed by a beep.

2.4 Local connection via APP

The "Smart Solution" DConnect APP is the interface for local control of the Esy I/O device. Via the DConnect APP you can update the product and configure the main parameters of the device with the convenience of an easy-to-use and always handy APP. Via the APP it is possible to interact locally with the product through the "Direct Connection" menu accessible directly from the main page of the APP.

Figure 3: Dconnect APP main screen

Select the image related to the Esy I/O product, and follow the instructions during the process.

2.5 Updating the software

Updates ensure a better use of the services offered by the product. Before starting to use the product, make sure that it is updated to the latest software version available. During the software update the products involved cannot carry out their functions. For this reason a manned update is recommended.

NOTE 1: The update can take up to 5 minutes per product and when it ends the device will restart.

2.6 Dab Proprietary Wireless connection

The basic function of the Esy I/O is that it can be connected by means of a wireless interface 802.15.4, equipped with a DAB proprietary protocol, to one or more supported e.syline products.

The proprietary wireless connection is also necessary for the alignment to use Esy I/O as Modbus gateway (see Paragraph 2.10)

Proprietary wireless connection procedure

It is possible to connect the Esy I/O to a device or to several devices using the following procedure:

- Put the device to be connected into association status (see the manual of the product to be associated)

- Press the key on Esy I/O for a least 5 seconds, then wait for the blue led (seeTable 1) to light up with a fixed light.

To interrupt the procedure it is possible to press the left key on the Esy I/O.

ENGLISH

In the event of a momentary disconnection of the associated device, the blue LED will flash to indicate that the device is not connected, but is trying to restore the connection.

The wireless network configuration is maintained even in the case of a temporary power cut or if the device is switched off.

Disconnection procedure and resetting of the wireless configuration.

Hold down the key for 5 seconds. If the operation has been successful the blue LED will be off.

2.7 Optoisolated digital inputs

ESY I/O has the possibility to connect up to 4 optoisolated inputs.

The 4 digital inputs are optoisolated, they can be energised either with continuous negative and positive voltages or with alternating current at 50-60 Hz. Table 2 describes the characteristics and the limits of the digital inputs:

Characteristics of the inputs
	DC inputs [V]	AC inputs 50-60 Hz [Vrms]
Minimum switch-on voltage [V]	6.2	4.5
Maximum switch-off voltage [V]	2	1.5
Maximum admissible voltage [V]	40	40
Current absorbed at 12V [mA]	1.4	1.4
Max. accepted cable section [mm2]	1.5

Table 2: input characteristics

The optoisolated terminals are connected by applying a voltage to the terminals or by connecting the common signal to GND as a jumper and connecting the In signal to a contact (e.g. float, pressure switch, etc.)

Figure 7: Output Status Display

2.9 Remote pressure sensor

The Esy I/O allows the use of 1 remote pressure sensor, directly on the 4-pole connector PR1 (see Figure 8).

ENGLISH

Figure 8: Connection of the pressure sensor

The mode of use will depend on the settings made on the device/group of devices (see associated product manual). Via the Dconnect APP, it is possible to select the sensor used.

Figure 9: Pressure Sensor Setting Page

The following sensors are currently supported:

1) HUBA pressure sensor 0-25 bar

2.10 RS485 Modbus RTU connection

Esy I/O can be used as an RS485 gateway, with MODBUS RTU protocol, in order to perform data monitoring and control on devices supported by Esy I/O.

ENGLISH

Wiring

Modbus communication with 2-wire RS485 contemplates the use of 3 cables (A, B and GND). Connect the 3 cables correctly. It is recommended to use a screened 2-pole cable, with a twisted pair, adapted to 120 ohm if termination resistors are to be used.

Figure 10: Rs485 Modbus Wiring

MODBUS Terminals	Description
A	Terminal -
B	Terminal +
GND	Reference

Table 6: Description of Rs485 Terminals

The typical connection with an RS485 BUS is shown below.

The recommended connection is always of the Daisy chain type (option 1). Do not use star (option 2) or ring connections. The termination resistors, if necessary, must be inserted in the first and last device on the bus (e.g. Figure 11: The termination resistors must be inserted in Master BMS and Device n) Figure 11: Examples of bus wiring.

The maximum recommended number of connected devices is 32, consistent with other devices in the network. The length of the cables depends on the baud rate chosen, i.e. the higher the baud rate, the shorter the cable length.

3. PROBLEM SOLVING

Before starting to look for faults due to the wiring it is necessary to disconnect the power supply to the pump (take the plug out of the socket).

Below is a list of possible problems:

Problem	Problem description	Possible solution
Power led off	No power supply	Check power supply wiring
		Check for short circuits due to incorrect wiring
Error Insufficient supply voltage	Board power supply voltage not sufficient	Check for overloads due to incorrect wiring of sensors, inputs and outputs
Pressure sensor error	Pressure sensor out of range	Check that the pressure sensor connection is correct (PR1 connector)
Green pressure sensor led not active	Although the pressure sensor is connected, the led does not work	Make sure the pressure sensor is enabled (proceed via APP)
Modbus communication not working	Modbus communication not working	If Modbus LED is GREEN:1) Check that Modbus is enabled, via APP (Modbus Mode parameter = enabled)2) Check that Modbus parameters are correct (Baud rate, parity, stop bits, ID), via APP3) Check RS485 wiringIf Modbus LED is RED:1) Make sure that wireless communication between pump/group and ESY I/O is active.
