Integrating, communicating, controlling.

The networking of building technology system is a good way to increase convenience, safety and security while cutting energy consumption and optimising operations in new plants as well as with retrofitting or renovation.
Modbus solutions from Belimo permit cost-efficient and easy-to-manage integration of HVAC air/water final controlling elements and of sensors.


Actuators for Modbus

The interface installed in the Modbus actuators enables the direct connection of HVAC final controlling elements to Modbus RTU. In addition to such communications parameters as address, baud rate and transmission format, other actuator parameters such as running time or scaling can also be set with the Service tool ZTH-GEN. One sensor can also be connected to each Modbus actuator. This can be a passive or active sensor or a switching contact. This makes conventional sensors communications-capable in a very simple fashion.


Gateway MP to Modbus

The signals of up to eight MP actuators and the signals of the sensors that are grouped together via the Belimo MP-Bus are converted to Modbus RTU by the Gateway UK24MOD. The Modbus parametrization (address, baud rate,...) takes place with DIP switches. The MP-Bus assignment is determined automatically. The gateway solution combines the advantages of the inexpensive MP actuator product range offers the most comprehensive array of communicative motorisation solutions.

CAREL and the dreaded 'NO LINK' Screen! Picture the scene, you've just downloaded a fresh new piece of software onto a controller but rather than the a new interface, you're met with a big fat 'NO LINK' message on the display. Or maybe you've just ran a factory reset to default settings and have come up against the same issue?  These are all possible causes for the common problem encountered by many of our customers, deemed the 'NO LINK' screen! (capitals for emphasis) As well as the two already mentioned, other common causes of the issue are a result of: A faulty connection between the Controller and the Display A faulty Controller  In any case, this issue is relatively simple to fix and our Managing Director, Stefano - having been in the Industry for 15+ years - has put together a video guide on how to do so. Watch the video below to see how to overcome the dreaded 'NO LINK' Screen!   www.i-acs.co.uk

Cold Rooms for food storage

Food storage uses various procedures that vary based on duration: Refrigeration, if the food must be stored for a short period of time (0…7 ° C). Freezing, deep freezing and lyophilisation (freeze drying) if it must be stored for long periods. When deep freezing the product it must reach a temperature of -18 ° C in less than 4 hours while for regular freezing the product can take more than 4 hours to reach -18 ° C. During lyophilisation the product is dried following a forced evaporation of the water component of the product. In the food industry, refrigeration is one of the most delicate and complex applications because food requires treatment at different temperatures depending upon the processing phase. Refrigeration slows the growth of bacteria on food. The technique is based on the extremely quick and intense action performed by the cold temperature that allows the organoleptic qualities of the food to be kept intact, prolonging storage time. Systems...
