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.

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 for standard resistance sensors using an Ohm measuring device.
Controller for operation of evaporator on water chiller 16 pages. This procedure can be avoided by looking at danfooss service menu; here it can be skc immediately in case of doubt, double check with the thermometer whether the value is realistic. This valve is equipped with a stepper motor and is controlled by an electronic elc e.
Due to tolerances in the actuator, the setting value must be 10 K lower than shown in the curve. 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.
Remote service is also possible for this control system. The “D component” in PID control also optimises the control characteristics in the case of a sudden change to the reference value.
The “EKC ” control has three different transient processes available. The controller is operated using two push buttons. Either can be necessary. Page 13 If the actual application has a requirement re- garding max. The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. Digital controller for refrigeration and defrost, 1 relay pages.
The individual status codes have the following meanings: Page 6 When you change the setting to danfos other language you must activate o04 before “the new language” can be visible from the AKM program. Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation. This sensor measures the actual value of the outlet air temperature of the evaporator and feeds this back to the controller. Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.

Got it, continue to print. Page 11 The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided. Of course, it is also the case here that the dew point for dehumidification must always be undershot.
Page 16 Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Solution for large plants If connection sizes larger than 54 mm are required for the suction line, it is recommended that you implement a solution with a main valve.
This heating closes and opens the valve. However, in this case, more time must be planned for achieving the required reference value.
Refrigeration specialists know that the topic of “humidity” plays an important role in refrigeration, especially where unpackaged goods, meat, vegetables and fruit are concerned. Even with a temperature difference of just 31 K, the control forces a small opening to prevent the control from overshooting the set point.
The second option only allows slight undershooting. Service The service menu of the electronic controller elc of particular interest to the fitter upon commissioning or servicing of the plant. P control involves standard regulation according to the deviation example: After defrosting has been initiated, its standard procedure must be defined by setting the control appropriately. Therefore, the control gives the valve the command “open valve” in situations where the reference value is far lower than the actual value.
Page 8 If you need to return to the factory-set dwnfoss, it can be done in this way: This means that this media temperature control can be integrated in complex Danfoss control system networks.
B – Product specifications
The first option is the fastest possible refrigeration. Add to my manuals Add. It is possible to equip the control with a LON module and record the appropriate data using a master unit and to intervene in the control system remotely using a modem connection. And on the other hand, you can see immediately which values the control takes for granted. Operation The controller is operated using two push buttons.
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.

Don’t have an account? This can be done using special software type “Danfoss AKM”. Comments to this Manuals Your Name. 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.
