A frequency controller allows you to adjust the speed of the silo auger. You can define the feed quantity and composition in a feed table, and enter the feeding times and quantities in a biorhythm table. This allows you to supply the desired type and quantity of feed to each animal or feeding point. It is possible to use a sensor to control the feeding cycles.

PRINCIPLE Crusher Dosing In Thomas Multifeed can control a crusher to crush the desired feed components before transferring them to the weigher (or mix weigher). The feed components are transported from the silos or dosing devices to the weigher. It is possible to crush the feed components before they go into the weigher. Mini-dosing Weighing Feed supplements can be added to the weigher (or mix weigher) by up to four dosing devices. This can be done based on time or pulses. The feed is weighed with a feed weigher. If desired, a mixer can mix the feed. Weigher (or Mix Weigher) ● Directly into the circuit The feed types from the various silos are weighed with the weigher (or mix weigher). A feed portion can consist of one or more feed types. After the weighing is complete the amount of feed used is automatically subtracted from the silo contents. After the feed is mixed (if desired), the feed is discharged into the bin. The feed is fed into the circuit from this bin. This dosing out process can be done in several ways: ● Using one or more augers ● Directly into the circuit ● Using one or more valves ● Using one or more augers ● Using one or more valves Dosing Out The weighed feed is then collected in a bin and dosed out into the circuit. This can be done in several ways, for example: Transport The feed is transported via the circuit(s) to the feeding point. Thomas makes sure that the feeding-point valve is opened at exactly the right time. Circuits Thomas Multifeed can control up to 16 circuits. When there is more than one circuit, the following options are available for filling the circuit: ● Simultaneous The circuits are filled in cycles. First feed place 1 of circuit 1, then feed place 1 of circuit 2, and so on. Once all the first feeding points of each circuit have been filled, the Thomas Multifeed will continue with feeding point 2 of all circuits. ● After each other The circuits will start after each other. As soon as the first circuit is ready, the second circuit will start. This option can be selected when the capacity of the silo auger is not sufficient to fill the circuits simultaneously. CONTROL FUNCTIONS Silos Thomas Multifeed can control up to 30 silos. With a frequency controller it is possible to control the speed of the silo auger. This allows more precise dosing to the weigher (or mix weigher). The silo allocation is flexible, so you can store the feed components in different silos at different times. Feed Consumption Registration Biorhythm Table Thomas Multifeed keeps a record of how much feed is weighed by the feed weigher per day. This is tracked separately for each type of feed. The biorhythm table is used to determine how much feed is dispensed at the various feeding times. Based on the data from the biorhythm table, feed table and management program, Thomas Multifeed calculates how much feed is required per feeding point per feeding time. Up to 10 biorhythm tables with 10 inflection points can be entered. Valves Thomas Multifeed can control up to 512 valves. These can be allocated independently per barn, room or sty. Thomas Multifeed can control up to 32 valves (feeding points) per room (max. 128). The valves can be connected both pneumatically and motor controlled. Compressor Thomas Multifeed can switch on a compressor to control the feed valves. This can be done in the following ways: ● Compressor 24 hrs: The compressor is switched on continuously ● Compressor start-up: During each feed cycle the compressor is first started up before the feed is weighed out. Sensor Feeding To avoid feeding unnecessary portions, Thomas Multifeed is capable of sensor-controlled feeding. A sensor is placed at each feeding point, and prior to the feed cycle the feeding points included in that feeding cycle are checked to determine whether they should get a new portion. Inspection It is essential that all the components of the feeding system keep working correctly. With Thomas Multifeed, it is possible to inspect and monitor the most important aspects of your feed system, such as: ● Silos: Operation of silo augers / minimum content of silos ● Circuits: Circulation guard / cable rupture / circuit fault / status of (final) limit sensors GENERAL Feed Table The feed table makes it possible to set how much feed each animal gets per day. The feed composition is also entered here. Based on the feed table, Thomas Multifeed uses the day counter or the weight to calculate the amount of feed that an animal gets per day. Up to 20 feed tables with 20 inflection points may be entered. Alarm Thomas Multifeed has two types of messages: a warning or an alarm. In the case of a warning, a message will appear on Thomas Multifeed display. In the case of an alarm, the alarm contact will also be broken. All messages are saved in the alarm log with start and end times. Diagnostics In diagnostics, you can call up a number of additional functions. These include the status of the feed weigher, the assigned silos and circuit sensors and your computer’s serial number. Communication ThomApp Thomas uses various communication protocols, such as: The ThomApp makes it possible to operate the barn computers remotely with your smartphone or tablet. After installing the software on your device, you can establish a connection with Thomas computers in the barn via the Internet and the SmartLink-RM and thus take control of them. The keys and screens in the app are exactly the same as those on your Thomas computer. This makes operation very familiar and allows you to control the barn computer quickly and accurately, no matter where you happen to be at that moment. ● CAN Backbone Via the CAN Backbone you can link multiple Thomas computers together in a network. You can then use a SmartLink-RM to connect a PC or modem to this network of Thomas computers. ● CAN Local Thomas communicates with the CAN I/O modules by means of the CAN Local. You can expand the inputs and outputs of Thomas Multifeed with the following CAN I/O modules: ● ○ CAN-IO-LCA (D) ○ CAN-IO-12-6 ○ CAN-IO-16-00 ○ CAN-IO-00-16 Ethernet Via Ethernet, it is possible to directly connect one Thomas computer to the Prisma management program. If you would also like to use the ThomApp, you will need to connect a SmartLink-RM to your Thomas via the CAN Backbone. Prisma Management Program You can use the Prisma management program to control Thomas Multifeed remotely from your PC or tablet. Ease of use and the graphical display are key factors here too. You can see at a glance an overview of all the barns in your company, which systems are active within each barn and whether an alarm has been generated. In the management program, various items of data are recorded that will keep you informed of, for example: ● The current silo contents ● The feed consumption per feeding point ● The water consumption This data can easily be converted to tables and/or graphs so that you can analyze it quickly and easily.
