Backup WBC Settings

IMPORTANT: Before changing any Tunnel Master wbc settings, ICS recommends to backup your current settings.

Create a Backup of your WBC settings

To backup WBC settings, follow these steps:

1. Open a web browser and navigate to the WBC IP address.
   The Default value is 10.0.0.200 but this may vary depending on site preference.
2. Log in to the WBC from a locally networked computer using credentials provided during initial setup.
   NOTE: Work with your team or contact ICS if the credentials have been lost or forgotten.
3. Select Configuration > Backup/Restore.
4. Click the Backup Configurations to a File button
5. Confirm the download in your browser, if prompted.
6. Click the Browse button to locate the WBC_Backup_DATE_TIME_VERSION.bin file.
   NOTE: DATE, TIME, and VERSION variables appear with the actual date, time, and version on the WBC.

Restore Backup Settings

The backup file saved can be reloaded or restored at any time.

1. Log in to the WBC from a locally networked computer using credentials provided during initial setup.
   NOTE: Work with your team or contact ICS if the credentials have been lost or forgotten.
2. Select Configuration > Backup/Restore.
3. Click the Backup Configurations to a File button.
4. Click the Browse button to locate the WBC_Backup_DATE_TIME_VERSION.bin file.
   NOTE: DATE, TIME, and VERSION variables appear with the actual date, time, and version on the WBC.
5. Click Restore Configurations to restore the WBC using the settings in the backup file.
   NOTE: The tunnel controller will not perform washes while settings are being restored.

Relay Settings Overview

After safely backing up your existing WBC settings, prepare the Relay Settings section in the WBC:

1. Access Relay Settings by logging into the WBC and navigating to Configuration > Relays.
2. Define the Output Relay Number that is wired to this piece of equipment in the Output Relay.X field. The X variable will be used for alternate functions, such as retracts.
   Example: Set a piece of equipment wired to output 5 as 5.0. Set the Virtual Relay for this piece of equipment to 5.1
3. Name: Name of the equipment
   Recommended naming convention includes: Equipment-Order-Function
   Equipment = The name of the arch/motor/equipment
   Example: Soap Arch
   Order = Optional variable to define this equipment from similar functions on other Relays
   Example: Soap Arch 1
   Function = Another optional variable for retracts & alternate functions
   Example: Soap Arch 1 Retract
4. Start: The distance from the entrance eye to the equipment. This can be in inches or in pulses, depending on the Pulse Length Setting.
5. Extend: How many inches/pulses the relay will be active for beyond the Part of Car measurement.
   Example: Extend of 20 on an output set to “All of car” will activate for the length of the vehicle plus an additional 20 inches/pulses, depending on the Pulse Length Setting.
6. Look Ahead: The Look Ahead feature keeps a function or piece of equipment energized if the next vehicle is within the programmed Look Ahead value. The Look Ahead value is the distance behind that piece of equipment’s Start time.
   Example: If a car is at the dryers while another car has entered the tunnel and they are past the Look Ahead distance, the dryers will stay energized.
7. Type: See table below:
   
   

   Mandatory	When an output is set to Type Mandatory, that output will activate for every wash automatically and does not need to be added to a service in order to function
   Selective	When an output Type is set to Selective, that output will activate only when added to a service. This can be a Base service, Extra service or a Retract service
   Deselective	When an output Type is set to Deselective, that output will activate for every service unless that output is added to a service. Deselective outputs are most commonly used for Retract services.
   External	Used for things being controlled outside of the tunnel. These may include Conveyor, Vacuums, and Timed outputs to turn on VFDs.

8. Part of Car: Defines which portion of the vehicle measurement is affecting the activation time of this relay. Refer to the following diagram showing the measurements of a car measuring 100 inches.
   
   
   
   Additional Parts of Car:
   
   

   Pickup Front Half*	The beginning part of a vehicle measurement with a pickup bed, this part of car starts at the front of the vehicle and ENDS where the Bed Drop value is detected by the pickup bed sensor
   Pickup Rear Half*	The latter half of a vehicle measurement with a pickup bed, this part of car STARTS where the Bed Drop value is detected by the pickup bed sensor and ends at the rear of the vehicle
   Oversized Vehicle Top*	Used to detect an oversize vehicle after minimum car length is reached. Detecting vehicle Starts from Front of Car and up to Top Distance from the floor.
   Oversized Vehicle Hood*	Detecting vehicle starts from StartOfCar and up to 18 inches from floor for determining Start of Car. If vehicle is not found, then detection starts when vehicles Top is detected at configured Vehicle Top Distance from tunnel floor.
   Windshield*	Distance between Oversized Vehicle Top and Oversized Vehicle Hood
   Upper Side*	Equipment with this part of car will only activate for the duration of the Oversized Vehicle Top. The start will be when the top was first reached and the end will be where the distance from top began to drop.
   Tire All	Activates from a tire switch for tires or wheels. On a Tire Output, the Start Time is where the equipment in the tunnel is located and the Extend Time is the length of time the output will stay on.
   Entrance Sign	Activates as soon as the wash is loaded to the front of the stack and will turn off as soon as the minimum car length setting has been detected by the photoeyes.

   *Requires Pickup Bed Sensor to Operate
9. Flash: If set to On, the relay will toggle on & off in timing with the Flash on/off settings in the tunnel settings section instead of holding the relay On during the part of car.
   • TYING ANYTHING OTHER THAN AN INCANDESCENT LIGHT TO AN OUTPUT THAT IS SET TO FLASH CAN RESULT IN DAMAGE TO TUNNEL EQUIPMENT AND POTENTIAL ELECTRICAL ISSUES.
10. Wet Down: If set to On, then this output is activated during the wet down function.
11. Panic Stop: The Value of this setting defines how the relay responds to a panic condition.
    • If set to OFF, the relay will turn off during a panic Stop.
    • If set to ON, the relay turns on during a panic stop.
    • If set to NC, there is no change to the state of the relay during the panic stop. If it was ON before the panic stop, then during a panic stop it remains ON.
12. Staggered Start: Variable that can be assigned to offset the electricity peak demand when restarting the tunnel after a panic stop.
    
    Refer to the Tunnel Master WBC User Manual for specific details on each setting.

Considerations:

1. Make a Backup of the Tunnel Master WBC settings before AND after making any settings changes.
2. There is no Save button that must be pressed to finalize any settings changes. As soon as a value is put into a field, it is automatically saved.
3. Please see the Retracts in Tunnel Master WBC User Manual document for advice on programming Retracts.
4. Log Out of the WBC web portal if you are done making changes to your settings.
