Legal Note

 

Specifications

Requirements

• RTD sensors, type PT-100 or PT-1000
• VINT Hub (HUB0001_0)
  • HUB0001_0 replaced the HUB0000_0

• RTD Phidgets (TMP 1200): supports 2-, 3-, 4-wire RTD mode
  The TMP 1200 only allows one RTD sensor per device. You need one TMP1200 per RTD sensor. 

• Phidgets cables (e.g. 3002_0, 3003_0, 3004_0 )
  There are various types of Phidgets cables available for the connection. Please consult the Phidgets website for the TMP1200, and click on Connection & Compatibility to learn more about whether the Phidgets cable you use is supported by the Phidgets device.
  

 

Setup options

 

Depending on your setup and the type of probes, there are two connection options: 

1. Direct connection
2. Dual probe connection

 

Direct connection

A direct connection applies when adding new probes independently from the roaster's readout. The newly added probe can be connected directly to the Cropster Connector. 

 

Dual connection

A dual connection applies when the roaster is equipped with a dual probe. A dual probe is a probe with two sensors inside the hull and two pairs of wires that allows a simultaneous connection to Cropster and the roaster's readout.

 

VINT Hub + TMP1200 installation

VINT Hub HUB0000 (now HUB0001_0) on the left, connected to a TMP1200 on the right, using a Phidgets cable to perform the connection between the two devices. A 4-wire mode RTD temperature sensor, is connected into the TMP1200.

1. Follow the probe cable from the tip of the probe to its end where the wires appear.
   In case of dual probes, take the free end that is not connected to the roaster.
2. Confirm the number of wires available for your PT-100/PT-1000 RTD probe, and follow the next step accordingly:
   

   Two-wire:  To connect a 2-wire RTD to the RTD Phidget, connect one wire to the RTD+ terminal, and the other to the RTD- terminal. Then connect the EXC+ terminal to the RTD+ terminal and the EXC- to the RTD- terminal with two short wires. This is the simplest wiring setup for an RTD, but also the least accurate because the resistance of the leads are not taken into account.

   Three-wire: Your RTD should have two wires that share a color; connect one of these wires to the RTD- terminal and the other to the EXC- terminal. The differently colored wire connects to the RTD+ terminal. Then connect the EXC+ terminal to the RTD+ terminal with a short wire. In a three-wire RTD, the extra wire is added to measure the resistance of one of the leads. This calculation assumes that both leads have the same resistance.

   Four-wire: To connect a four-wire RTD, simply connect one pair of same-colored wires to the RTD+ and EXC+ terminals, and the other pair to the RTD- and EXC- terminals. A four-wire RTD is normally used in precision measurement, when the assumption that both leads have the same resistance is not accurate enough. Unfortunately, the RTD Phidget does not support this particular feature of four-wire RTDs. It does support the use of four-wire RTDs using the same assumption as three-wire mode.

3. Connect the TMP1200 to the VINT Hub using your Phidgets cable.
4. Repeat the installation steps for each RTD sensor, you wish to connect to a TMP1200.
5. Connect the VINT Hub to the computer with the provided USB cable to your computer and proceed with the software setup.

Roasting Intelligence (RI) Setup

Installing the Roasting Intelligence (RI) software

1. Download RI.

2. Complete the installation process by following the steps provided.

3. Download the Phidget driver.

4. Enter your username and password.
   Use the same login information that you use to access the online platform C-sar.

5. Click the Login button.

Establishing a connection to the machine

1. If you are setting up RI for the first time, click the Select machine button in the banner at the top or click Preferences > Machine > Configuration bottom left to access the Preferences screen. 
   📚 Learn how to use the keyboard shortcuts in RI.
2. To choose the Roast machine, click on the dropdown menu in the Machine section. 
   

   💡 After selecting the machine from the dropdown menu, the roast machine settings may automatically be filled in. You have the flexibility to edit these settings at any time to ensure they align with the specifications of your roasting machine. 

   📚 Learn how to add a new roast machine. 
3. After selecting the machine all supported measurements will load.
   Change the order of the measurements by using the  Drag and Drop icon and moving it into position.
4. Switch on the measurements you would like to enable and select Phidgets RTD Sensor (TMP1200) from the dropdown for all measurements connected to the VINT Hub's ports, via a TMP1200.
   💡 Make your measurement readouts more compact. Choose the size of your measurement readouts by selecting either the Small or Large view for display. 
5. Select the Hub port.
   💡The Hub port refers to the port on the VINT Hub. If the TMP1200 is connected to VINT Hub's port 0, select 0 under Hub port.
   
6. Select the Type of RTD temperature sensors.
   💡Please check the manufacturer's probe specifications, to identify the type. e.g., An RTD with 100 ohm resistance, and a 3850 ppm/k, corresponds to the PT100_3850 option.
   
   • PT100 or PT1000 = Platinum sensor with 100 or 1000 ohm resistance
   • 3850 or 3920 ppm/K = temperature coefficient 
7. Click on the  Gear icon to open more settings. 
8. Click on the Wiring mode dropdown menu, and select the wiring mode corresponding to the number of leads/wires coming from your PT100/PT1000 probe.

9. Select Phidgets RTD Sensor (TMP1200) from the drop-down for all measurements connected to the VINT Hub's ports, via a TMP1200.

10. Wireless VINT Hub (i.e. HUB5000) ONLY:
    • Enter the hostname/IP address and port.
      • Hostname/IP address: 
        The hostname or IP address of your Wireless VINT Hub
      • Port: The port of the Phidget Server configured on your Wireless VINT Hub.
11. Click OK.
12. Click Save to finalize the changes.

After saving the changes, RI will automatically restart. If the setup was successful, you will see the temperature values displayed on the right-hand side of the RI screen following the restart.

Troubleshooting

If the RI indicates No source connected and/or you cannot see any measurements, please check the following: 

• Is the TMP1200 connected to the VINT Hub? 
• Is the VINT Hub connected to the computer?
• Is the Phidgets driver installed?
• Mac only: has the Phidgets driver been enabled in the Mac's Security & Privacy settings?

If the temperature deviates a few degrees:

• Try the different options for your type of RTD sensor under the Type drop-down menu.
