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.

Operation The controller is operated using two push buttons. Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Page 5 Due to tolerances in the actuator the value must be set 10K lower than indicated dnafoss the curves on page Page 11 The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting.
This dabfoss closes and opens the valve. To print the manual completely, please, download it. By pressing ‘print’ button you will print only current page.
Precise media temperature control
After defrosting, the drip-off time begins. In the case of a media temperature control for refrigerating plants with a pipe size of up to dxnfoss mm, an electrically controlled valve e. For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i.
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. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
This point can be danfozs influenced with an electronic suction throttle system: The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. Home page Service and support Case studies Precise media temperature control. Service The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.
Digital controller dxnfoss refrigeration and defrost, 3 relays pages. Special attention must be paid to the start-up phase of regulation. In the case of hot gas defrosting, the “KVS” valve closes during the defrosting procedure. Page 16 Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. If you need to return to the factory-set values, it can be done in this way: P control involves standard regulation according to the deviation example: This can be easily achieved with electronic suction throttle regulation or media temperature control.
However, in this case, more time must be planned for achieving the required reference value.
The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”. When you change the setting to an other language you must activate o04 before “the new language” can be visible from the AKM program.
And on the other hand, you can see immediately which values the control takes for granted. Here, the main valve with pilot is also fitted in the suction line. A fast-reacting temperature sensor e. Got it, continue to print.

In the case of PI regulation, the “reset time” I component can be changed individually, which simultaneously leads to the adaptation of the reaction speed of control. A completely open valve ensures maximum refrigeration danfosa therefore the lowest possible outlet temperature in the actual load situation. Of course, it is also the case here that the dew point for dehumidification must always be undershot. This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned.
Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation. 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 adnfoss is quickly achieved.
The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.

On the one hand, they can be read quickly, which saves the effort of measuring with the temperature gauge. This procedure can be avoided by looking at the service menu; here it can be seen immediately in case of doubt, double check with the thermometer whether the value is realistic.
In the case of electric defrosting, the “KVS” is opened.
All parameter values that begin with “u” display danfoss plant values ejc are important for all types of troubleshooting and for evaluating the state of the plant. After defrosting has been initiated, its standard procedure must be defined by setting the control appropriately. A valve that is almost closed creates a high outlet temperature. This also applies to products already on order provided that such alternations can be made without subsequential changes being necessary in specifications already agreed.
Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing. Once these processes have finished, the refrigeration process is restarted. Add to my manuals Add. This can be done using special software type “Danfoss AKM”. Don’t have an account? Digital controller for refrigeration and defrost, 1 relay pages.
A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage.
