- Modify the programme language if necessary (En : English by default)
* Select the zone of the value to be changed
* Adjust the value using the coder knob
2.2 OVEN SETTINGS
- Select the "TOOL BOX" menu
- Select the "Technician parameters" screen
- Enter the password : « SAVB »

2.3 WATER TREATMENT COUNTER
This only function if there are 2 separate supplies to the oven.
- Select the "TOOL BOX" menu
- Select the "Client parameters" screen
- Enter the password « CHEF »: Permanent password (lower or uppercase)
- Validate “V”: When finished, if the code is correct access the menu in not re-enter the PIN number.
Water treatment capacity
- To modify or enter the value for the capacity of the water treatment system (in litres). Set to zero by default (if the oven does not have a dedicated
water treatment system).
* Select the zone to be changed
* Adjust with the coder knob.
- After any regeneration of the water treatment, reset the counter as required.
* Press « RESET »
* Confirm by pressing « YES ».
➔
The water treatment system’s capacity in litres. Reset.
By default, set to zero (if there isn’t dedicated treated water supply to
the oven)
If the water treatment capacity meter is equal to or less than 0, error code i8 will be displayed.
2.4 SCREEN CARD SETTINGS
These screens are common to several types of unit. After sales provide a non-product specific unit but it will be configured automatically when
connected to the equipment in question.
This configuration is irreversible. Once a screen has been programmed to control an oven it cannot be fitted to any other type of equipment. If
necessary it must be returned to the factory for re-initialisation.
Required for configuration: a blank FastPad USB stick, or blank USB stick with the following characteristics:
- Max capacity = 32 Gb –Formatted for FAT32 (Default unit allocation size = 4096 bytes) or formatted for FAT (Default size = 32 Kb).
- The stick need not be empty but a minimum of 5 Mb of free space is required; Files already on the USB stick will not be erased (But always
back up your personal data). Temporary files will be written but they can be erased afterwards.

Follow these steps after installing the new screen on the appliance by following the instructions in the paragraph “Screen board”, and chapter
“Component change procedure”:
- Connect a USB stick (as defined above) to the USB port of the oven.
- Turn the appliance on.
- Select the language on the installation screens (2 available versions: French or English).
- Select which type of appliance the screen will be configured for and confirm by pressing “OK”.
* If the appliance does not match, or no configuration is found, turn off the power and check the position of the “micro switches” located on
the FastPAD 2 power unit (see “Position of the micro-switches” in the “Maintenance program” chapter).
* If necessary, ensure that the power assembly and/or the communication between the various circuit boards is working properly (see
“Maintenance program” chapter).
- Wait for the configuration phases to automatically run through.
- When the message « Installation complete” is displayed, press “OK” to start the interface.
- Remove the USB stick
- Follow the “Setting the oven” instructions to configure the interface.

3. MAINTENANCE PROGRAMMES
3.1 ELECTRONIC CARDS
The state of the LEDs represent the communication between the electronic cards and helps with diagnostics in the event of a breakdown
Significance of the LEDs on the FastPAD 2 power assembly and the FastPAD screen card:
LED Red ➔➔➔
Power on
LED steady
LED Yellow/Orange ➔
Emitting
LED steady or flashing
LED Green ➔➔➔
Receiving
A flashing LED is considered active as is a steady one.

3.3 CHECKING THE SOFWARE VERSION
The version of software can be seen in the “TOOLBOX” tab next to the serial number of the unit. Each card is identified by its assigned
software number :
Screen card sub assembly
IHM - Fla: IHM –Flash card
UC: UC card
Screen support card

The oven cannot be used whilst loading software
3.4.1 USB STICK
Required for configuration: a blank FastPad USB stick, or blank USB stick with the following characteristics :
Max capacity = 32 GB -Formatted in FAT32 (Default allocation size = 4096 bytes) or formatted in FAT (Default allocation unit size = 32
kilobytes).
3.4.2 SOTWARE FILE UPDATE
Download the software update file “CVxxx-SW.zip” from the WebAstech Vulcan maintenance site. Unzip the file.
Copy the file to the USB stick and run it:

This will allow you to control the input and output appliances and peripherals feeding the cards:
- Screen 1 gives control of temperature, door, water level.
- Screen 2 gives control of outputs to ventilation, heating, lighting, safety contactor, the vent outlet ….
- Screen 3 gives control of the hydraulics outputs, solenoids, wash pump and wash tank.
4.1 ACCESS TO THE MAINTENANCE SCREENS
- Go into the "TOOL BOX" screen
- Select the "Technical parameters" screen
- Enter the password “SAVB” password
- Validate “V”: if the code is correct the menu can be accessed if not return to inputting the PIN
