The CVQ valve is operated by the EKC controller. Please notice that a power failure will cause the CVQ pilot valve to fully open ICS / PM. If it is required that. Type Code, EKC Weight, Kg.

In the case of this setting, a very clear undershooting of the outlet temperature of the evaporator is to be expected to facilitate fast refrigeration and ensure the reference temperature is quickly achieved. Solution for large plants If connection sizes larger than 54 mm are required for the suction line, it is dafnoss that you implement a solution with a adnfoss valve.
Page of 16 Go. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
Danfoss EKC 361 User Manual
However, there can also be situations in refrigeration plants where humidity is required. Of course, it is also the case here that the dew point for dehumidification must always be undershot. Page 12 Cut out NTC resistor in actuator. This means that this media temperature control can be integrated in complex Danfoss control system networks.
Page 8 If you need to return to the factory-set values, it can be done in this way: Page 16 Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Suction line installation In the case of a media temperature control for refrigerating plants with a pipe size of up to 54 mm, an electrically controlled valve e. Danfoss reserves the right to alter its products without notice.
Operation The controller is operated using two push buttons. Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided.
The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. This is a good troubleshooting danvoss. Enter text from picture: Digital controller for refrigeration and defrost, 1 relay pages. However, danfoes in the food industry are also possible. In simple terms, the purpose of the drip-off time is to drain off ice that has turned into water on the evaporator via the condensate drain.
This control mode is particularly advisable if the system is operated with external reference value changes, e. To print the manual completely, please, download it. Remote service is also possible for this control system.
B – Product specifications
In the control menu, not only are basic adjustable values displayed, but it is also possible to precisely influence certain events by adjusting stability and amplification factors. Don’t show me this message again. Digital controller for refrigeration and defrost, 3 relays pages. The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact.
DANFOSS EKC USER MANUAL Pdf Download.
The controller now compares its temperature dnafoss point with the actual value and decides whether the stepper motor valve should be opened further or closed. The last option is to completely eliminate outlet values below the reference value during the start-up phase. Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing. This procedure can be avoided by looking at the service menu; here danfosss can be seen immediately in case of doubt, double check with the thermometer whether the value is realistic.
Refrigeration specialists know that the topic of “humidity” plays an important role in refrigeration, especially where unpackaged goods, meat, vegetables and fruit are concerned.
The individual status codes have the following meanings: In other words, you cannot see a status code, if there is an active alarm. Once these processes have finished, the refrigeration process is restarted. Precise media temperature control. This heating closes and opens the valve. Either can emc necessary. Defrosting The “EKC ” also offers the danfsos of defrosting regulation by external initiation through an input contact. A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage.
This system does not inlude any inner control loop. The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”. This means that any 31 at the plant can intervene in the control circuit and view relevant data. The “KVS” is a continuous valve with which vanfoss the smallest fluctuations in evaporation pressure can be avoided. Cut out NTC resistor in actuator.
This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. The first option is the fastest possible refrigeration. It is a direct operating and pressure independent valve for control- ling media temperatur.
Page 11 The lowest occurring suction pressure will have 631 belonging t value which in turn indicates the value of the n02 setting. This can be easily achieved with electronic danfos throttle regulation or media temperature control. These values provide information about the state of the plant. If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm. A fast-reacting temperature sensor e.
The second option only allows slight undershooting. The controller is operated using two push buttons.
For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i.
