Purpose

This article goes over standard troubleshooting steps for the PicoCooler Vision with Minus Forty - a Vision Smart Store cooler.

This article also covers how to access the hardware to ensure it is properly connected and secured.
 

Process

The below sections will go over:

• standard troubleshooting steps
   
• how to access the hardware to ensure proper connections
  
   

Standard Troubleshooting Steps

Full Unit Power Drain Reboot

Most unit issues can be resolved with a full unit power drain.

To perform a full unit power drain:

1. Ensure the battery backup is turned off by sliding the switch on top of the battery backup enclosure (found at the rear of the cooler) to the OFF position. (More information on battery backup can be found in the Battery Backup section of this guide, or the attached owner's manual.)
    
2. Disconnect both power plugs from the wall; allow the unit to sit without power for 2 minutes.
    
3. Plug the unit back in, and turn the battery backup back on.
    
4. Clear the unit Lockout alarm to remove the HSA Lockout and stop the beeping:
    
   1. Slide the protective cover on the Minus Forty Controller Module (found at the bottom of the cooler) to the left, and press and hold the U button and Down Arrow button for five seconds to begin the Cooler Health Safety Lock Delay. 
      (This mode prevents an HSA Cooler Health Safety Lock/Alarm from engaging/locking a unit, and clears any active lockout alarm.)
   2. When this mode has been entered correctly, the Minus Forty display at the base of the unit will now flash the word "dELAY" along with other unit data.
      
      
5. Allow the unit to sit idle for 10 minutes while the unit components and services come back online, before attempting a test transaction.
   
   Please Note: Interrupting unit startup with a test transaction can cause an error, and another reboot may be needed. 
   Keep in mind that the reboot button in ADM only reboots the Pico and not the PC, OptConnect, or cabinet controller.
    

HSA Lockout Reset

When there is an HSA Lockout (Health and Safety Lockout), the Pico will display the following error on screen: "Unable to unlock cabinet. Lock reset Required, please contact operator."

Two issues can cause the HSA Lockout error:

1. Power loss if the battery backup is off, or the batteries need to be replaced. 
   (Please see the Battery Backup section of this article for more information.)
    
2. The unit get above a safe temperature for too long.

If the unit is already at a safe operating temperature, the HSA Lockout error can be cleared by sliding the protective cover on the Minus Forty controller module (found at the bottom of the cooler) to the left, and pressing/holding the U button and Down Arrow button for 5 seconds. 

If done correctly, the Minus Forty display at the base of the unit will now flash the word "dELAY' along with other unit data. This is the same procedure as mentioned in the Power Drain section above.
 

Stuck on Castles Technology Screen

If the Pico unit is stuck on the Castles Technology screen, there is limited troubleshooting that can be done.

1. Power drain the Pico unit for several minutes.
    
2. If this does not work, please reach out 365 Support. The following is required if the unit is eligible for an in-warranty RMA:
   • A clear picture of the front of the unit.
      
   • A clear picture of the rear of the unit.
      
   • A 3-minute video of the Pico screen on the Castles Technology error or 2 photos time stamped 3 minutes apart from each other. The pictures must include the time stamp and screen of the castles screen.

Once this has been completed, the Tier 2 Support team will confirm if an RMA is needed, or if there are further troubleshooting steps to follow.
 

Access Hardware and Ensure Proper Connections 

Tools Required

• Philips-head Screwdriver
   
• Spare Cat6 Ethernet Cable (if troubleshooting with an agent is required)
   

Open the PicoCooler Vision

1. Locate the back panel cover of the PicoCooler Vision. Hold the cover in place with a free hand while removing first the top two screws, then the bottom two screws of this cover.  
   
   

2. Remove the cover to reveal the internal components. 

   

Components

OptConnect (Connectivity)

In the USA, the device uses the OptConnect Neo or OptConnect Max Aware to provide service. 
The device selects the best tower available from Verizon or AT&T. The OptConnect Max Aware is also capable of using a local ethernet connection if the network requirements are followed.

• When using a local ethernet connection please see the article: Network Requirements – Stockwell and PicoCooler Vision.

OptConnect Max Aware:

See below port diagram.

• The connection shown below is usually on the rear of the cooler unit and is for connecting the local ethernet line if available.

  

The PicoCooler Vision does not offer offline functionality; the device must be online to process payments. 

1. Now that the PicoCooler Vision has been opened, ensure that the OptConnect cable and PC power cable are both properly secured into the power outlet.
   
   

2. Confirm that the ethernet cable is running up from the back channel into the Optconnect.

   
3. Make sure the ethernet cable is running from the Optconnect to the PC.
    
4. If the blue light on the PC is not illuminated, check that the connector is secure.
   
   
5. Check the cables on the back of the Pico unit to make sure they are plugged into the correct ports. The controller cable (elbow shaped connector) should be connected to the left, black colored port. The straight ethernet cable should be connected to the center, silver colored port. See below image:
   
   
6. Confirm the brown, blue, and green wires are securely fastened to the communications adaptor.

Cooler Controller Module

On a PicoCooler Vision, the Cooler Controller Module is located on the front of the cooler in the bottom-right corner.

To access these buttons, slide the spring-loaded protective cover to the left.

This can be used to clear a Cooler Health Safety Lockout (HSA). Information on how to clear it can be found in the HSA Lockout Reset section of this article.
 

Battery Backup

The cabinet controller battery backup can be found on the rear of the unit. 
Its purpose is to provide power to the controller(s) and mechanical lock(s) during the main power failures, so that the controller can keep monitoring the cabinet temperature during prolonged blackouts.

To check whether the battery backup is functioning:

1. Ensure the battery backup switch is in the ON position.
    
2. Unplug the power cords from the receptacle to disconnect the main power to the unit. If the controller loses power and the lock engages immediately or within a few minutes, then the batteries in the battery backup enclosure should be replaced. 
   1. To replace the batteries, undo the screw on the battery cover and replace the eight AA batteries with a new set of alkaline batteries. 
      (Use high-quality brands such as Duracell, Panasonic, etc.) Ensure the battery polarity is followed as per indicators on the backup housing.
      
      
3. It's recommended to repeat steps 1 and 2 periodically, every 3 to 4 months.

(More details on battery backup can be found in the owner's manual attached to this guide.)
 

Cameras

The PicoCooler Vision uses 5 internal-facing cameras (or 4 cameras in each corner depending on the configuration purchased) to determine which items are being purchased by the consumer. 

1. With the PicoCooler Vision open, check that all 5 camera cable USBs are connected. 
   The cables for these cameras can be plugged into any USB port on the PC. (The order does not matter.)

   1. If there are add-on cabinets: ensure that the additional camera connections from the add-on cabinet are connected to the main unit PC, as shown in the Add-On Ambient Vision Cabinet Operator Guide.

      

      Please Note: If connections on the PC are changed, the PC will need to be rebooted. 
      The unit will need to sit idle for 10 minutes while PC services start up, before attempting a test transaction.

2. Check that the camera cables run up a side channel of the device, and out the back of the cooler to plug into the PC. 
   A putty material covers the hole in the cooler and forms a seal around these cables. This is needed to securely seal in the cool air.
   Since this sealing is mission-critical to the device, if there is any issue with the camera cable, please contact 365 Support at (888) 365-6282 or support@365rm.com to have a certified Due North cooler technician fix any issues.
   
   

Reinstall Back Cover

1. Reinsert all components as needed.
    
2. Hold the back cover in place, lining up the holes for all four screws. 
    
3. Reattach the bottom two screws first, then the top two screws.
