![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-05-2024-12-17-30-8617-PM.png?width=688&height=443&name=image-png-Sep-05-2024-12-17-30-8617-PM.png)

The electronic cards are:

- Relay card
- Display
- Inverter
- Depending on the oven options, there will be dedicated expansion boards.
- Plug-in gas (only in ovens with gas heating system)
- Plug-in SSR (only in units with electric heating system)
- Boiler expansion (only in units with boiler option)
- FastDry controller

The operation and the user interface of the appliance systems are managed by electronic cards.

  USB connection

  Plug-In 1 (all units)

  Plug-In 2 (floor units)

The relay board controls the operation of the unit based on the indications provided by the display that acts as a user interface.

analog inputs highlighted in green, digital inputs (open/closed) highlighted in blue; inputs and outputs with line voltage that are highlighted in red

 

#### **SOFTWARE/FIRMWARE**

The operation of the relay board is based on proprietary software that is generally identified as Firmware (FW).

The Firmware controls and regulates the operation of the device based on the operating parameters, inputs from the sensors and the settings given by the user on the display.

For obvious reasons the FW must be aligned with the SW of the display card.

If there is no dialogue, it is possible to update the FW of the relay board by connecting a USB stick to the USB port of the board: see SW UPDATE chapter.

#### **Scheda Display**

#### ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-16-2024-07-13-26-5733-AM.png?width=688&height=456&name=image-png-Sep-16-2024-07-13-26-5733-AM.png)

The display is composed by two separate boards; the display board and the encoder board which hold 3 encoders(the lower one has also function to power on).

Display is fixed to the front panel trough several bolt.

***Warning**: when replacing the display car to keep the right distance/pressure on the front panel because if too squeezed on the front layer more than one button will be pressed and any pressure will be acquired.*

#### **SoftWare & FirmWare**

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-05-2024-12-20-50-7572-PM.png?width=688&height=402&name=image-png-Sep-05-2024-12-20-50-7572-PM.png) |
| --- |

To run the firmware update, are required:

a) The SW and FW; you can find them on the web site [www.service-planner.lainox.it](http://www.service-planner.lainox.it/)

b) The USB stick (max 4GB – check for compatibility or use a LAINOX USB Key)

Download the firmware from the website, extract the files from the compressed folder and save them on the USB key

It is possible to update the firmware of the Display PCB and the I/O PCB.

Both are available on the LAINOX website. We suggest checking for updates monthly and updating all units during any repair and maintenance work.

#### **Display Software Update**

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-05-2024-12-21-29-4958-PM.png?width=688&height=322&name=image-png-Sep-05-2024-12-21-29-4958-PM.png) |
| --- |

a) Plug the USB stick into the USB socket.

b) Put the unit in standby mode

c) Select the menu key

d) Select settings

e) Scroll to ***firmware update*** and press the dial to confirm

f) Follow instructions and confirm the update

g) The system will download the files and a bar will show the progress.

h) Final confirmation to proceed

i) The old FW will be erased and the new one installed. When completed, switch off and on again with the USB stick connected, the display will flash and download continue.

j) To complete the process, reboot the unit before removing the USB key.

It is possible to update the firmware of the Display PCB.

Check and update the SW during every maintenance

#### Base board FirmWare update

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-05-2024-12-22-24-9892-PM.png?width=476&height=597&name=image-png-Sep-05-2024-12-22-24-9892-PM.png) |
| --- |

a) Switch off the power supply

b) Open the front panel

c) Plug the USB stick into USB socket on the I/O PCB.

d) Switch on the power supply

e) Wait 120”

f) Switch off the power supply

g) Unplug the USB key and close the front panel

After any FW update, check from *Settings-Firmware version* if the update was successful.

It is needed to update the firmware of the base board when updating the Display PCB.

Check and update the FW during every maintenance

#### **Inverter**

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-16-2024-07-20-03-9474-AM.png?width=688&height=366&name=image-png-Sep-16-2024-07-20-03-9474-AM.png) |
| --- |

A) Power input 230 +/- 10%

B) Bus connection to the relay board

C) Output terminals U, V, W with 400VDC

D) Dip-switch identification

E) On=1° inverter

F) 1  =2° inverter (for units with 2 motors/inverter)

If the inverter is replaced, always check and set the dip-switch D) and configure the new inverter from the Service level / Inverter management.

The inverter board, common to all oven models, control the fan motor based on the settings given by the relay board by BUS.

*Pay attention to the electrical contacts of the board and wait a few minutes after power off before operating on it.*

#### **Control**

 

![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-16-2024-07-21-39-4329-AM.png?width=688&height=271&name=image-png-Sep-16-2024-07-21-39-4329-AM.png)The inverter is equipped with a control system and self-diagnosis that communicates with the relays board via BUS and with the technician via the green and red LEDs that provide details on the status and operation.

The number of flashes of the red LED provides indications of the type of error (first flashing lasts about 1sec the other ½sec)

#### **Plug-in SSR**

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-05-2024-12-25-10-1664-PM.png?width=688&height=347&name=image-png-Sep-05-2024-12-25-10-1664-PM.png) |
| --- |

#### **Connection**

There are 2 connectors on which the SSR wiring is plugged:

J1 Chamber heating control

J2 Boiler heatign control

On floor units, where there are two fans and two separate heating systems, a second plugin is installed and must be connected to Plug-in 2

See Electric Heating chapter for more details

The SSR plug-in is installed on the Plug-in 1 connector of the relay board and acts as an interface between the relay board and the SSR by transforming the SSR activation frequency into a 12VDC signal.

#### **Plug-in Gas**

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-16-2024-07-22-39-0899-AM.png?width=688&height=322&name=image-png-Sep-16-2024-07-22-39-0899-AM.png) |
| --- |

#### **Connection**

Plug-In is plugged straight to relays board

**J1**  chamber blower control

**J2**  boiler blower control

**59**  I. chamber flame detection

**60**  I. boiler flame detection

**61**  Neutral line burner

The GAS plug-in is installed on the Plug-in 1 connector of the relays board and acts as an interface between the relays board and the burners.

*See Gas Heating chapter for more details*

#### **Boiler Expansion**

 

| ![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-16-2024-07-23-27-2132-AM.png?width=688&height=429&name=image-png-Sep-16-2024-07-23-27-2132-AM.png) |

**53**  L3 Max level probe

**54**  L2 Emergency level probe

**55**  Boiler ground

**56** L1 Empty level probe

**48** Phase

**49** Phase

**50** O. burner boiler 1 Z2

**46** O. pump Pb calout

**47** O. Solenoid V. S2 filling

**64** I. No flame boiler burner

**65** O. reset boiler burner
