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.

S according to entered setpoint.
Don’t have an account? The controller can be completely programmed using these two buttons combined with a three-digit display where all important data is displayed.
Page 11 The lowest occurring suction pressure will have a belonging t value which in turn indicates the danfose of the n02 setting. In the case of electric defrosting, the “KVS” is opened.
Defrosting The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i. 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.
Page 631 If you need to return to 36 factory-set values, it can be done in this way: However, in this case, more time must be planned for achieving the required reference value. 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.
Here it is important to eliminate even the smallest temperature changes so that the measuring results are not affected.
This can be done using special software type “Danfoss AKM”. 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. This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page The danfose component” in PID control also optimises the control characteristics in the case of a sudden change to the reference value.
Enter text from picture: A fast-reacting temperature sensor e. 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 EKC USER MANUAL Pdf Download.
However, applications in the food industry are also possible. If you need to return to the factory-set values, it can be done in this way: Digital controller for refrigeration and defrost, 1 relay pages.
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.
Controller for operation of evaporator on water chiller 16 pages. All parameter values that begin with “u” display actual plant values which are important for all types of troubleshooting and for evaluating the state of the plant. 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. This valve is equipped with a stepper motor and is controlled by an electronic controller e.
Page 16 Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. After defrosting, the drip-off time begins. The individual status codes have the following meanings: Here, the main valve with pilot is also fitted in the suction line. The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting.
Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing. If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm.
This means that this media temperature control can be integrated in complex Danfoss control system networks. Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation. Smart multipurpose refrigeration controller erc 21x series 36 pages. The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided. 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.
This system does not inlude any inner control loop. Page 12 Cut out NTC resistor in actuator. A valve that is almost closed creates a high outlet temperature. Precise media temperature control. 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 service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.
Of course, it is also the case here that the dew point for dehumidification must always be undershot.

The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. This means that any fitter at the plant ek intervene in the control circuit and view relevant data.
In applications such as this, constant nozzle air temperature from evaporators is the key to success. Page dafnoss Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page After defrosting has been initiated, its standard procedure must be defined by setting the control appropriately.
