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. The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.
After defrosting has been initiated, its standard procedure must be defined by setting the control appropriately. Digital controller for refrigeration and defrost, 1 relay pages. Page of 16 Go. The controller now compares its temperature set point with the actual value and decides whether the stepper motor valve should be opened further or closed. After defrosting, the drip-off time begins. Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing.
And on the other hand, you can see immediately which values the control takes ekd granted. In the case of electric defrosting, the “KVS” is opened. Different transient processes in the start-up phase Special attention must be paid to the danross phase of regulation.
DANFOSS EKC USER MANUAL Pdf Download.
The “EKC ” control has three different transient processes available. Page 11 The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting.
Either can be necessary. All parameter values that begin with “u” display actual plant values which are important for all types of troubleshooting and daanfoss evaluating the state of the plant. Got it, continue to print. It is therefore standard procedure for an experienced fitter to check the control sensor and, if necessary, the defrost sensor in electronic systems before the actual commissioning this is very easy to do ddanfoss standard resistance sensors using an Ohm measuring device.
This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. When you change the setting to an other language you must activate o04 before “the new language” can be visible from the AKM program. The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
To print the manual completely, please, download it. Operation The controller is operated using two push buttons. Page 8 If you need to return to the factory-set values, it can be done in this way: 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.
If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm. Don’t show me this message again. The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”. A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage. In the case of hot gas defrosting, the “KVS” valve closes during the defrosting procedure.
However, applications in the food industry are also possible. The second option only allows slight undershooting. This means that any fitter at the plant can intervene in the control circuit and view relevant data. This can be easily achieved with electronic suction throttle regulation or media temperature control.
The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. Here, the main valve with pilot is also fitted in the suction line. A defrost sensor in the evaporator package ends the defrosting process as soon as the temperature of the evaporator package has reached the temperature to which the sensor is set.
For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i.

This is a good troubleshooting aid. This means that this media temperature control can be integrated in complex Danfoss control system networks. The controller is operated using two push buttons. In other words, you cannot see a status code, if there is an active alarm. Page 6 When you change the setting to an other language you must activate o04 before “the new language” can be visible from the AKM program.
Danfos lowest danfss suction pressure will have a belonging t value which in turn indicates the value of the n02 setting. Furthermore, it is not necessary to fit an additional valve in the suction line since the “KVS” can also be used for this shut-off function.
Of course, it is also the case here that the dew point for dehumidification must always be undershot. Once these processes have finished, the refrigeration process is restarted.
By pressing ‘print’ button you will print only current page. The controller can be completely programmed using these two buttons combined danfkss a three-digit display where all important data is displayed. Comments to this Manuals Your Name.
Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Here it sanfoss important to eliminate even the smallest temperature changes so that the measuring results are not affected. Home page Service and support Case studies Precise media temperature control.

Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page Page 12 Cut out NTC resistor in actuator. 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. S according to entered setpoint.
