Page 16 Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. The controller can be completely programmed using these two buttons combined with a three-digit display where all important data is displayed.

A fast-reacting temperature sensor e. The “EKC ” control has three different transient processes available. This ekd mode is particularly advisable if the system is operated with external reference value changes, e.

The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. 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.

Refrigeration eck know that the topic of “humidity” plays an important role in refrigeration, especially where unpackaged goods, meat, vegetables and fruit are concerned.

Page 4 S according to entered setpoint. The “D component” in PID control also optimises the control characteristics in the case of a sudden change to the reference value. 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. Page 8 If you need to return to the factory-set values, it can be done in this way: Add to my manuals Add.

It is always easy to readjust a system like this through the eliminated condensate quantity at the evaporator. This also applies to products already on order provided that such alternations can be made without subsequential changes being necessary in specifications already agreed.

For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i. 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. On the one hand, they can be read quickly, which saves the effort of measuring with the temperature gauge.

Danfoss reserves the right to alter its products without notice. The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided. However, with “CVQ” an actuator is used to operate the valve instead of a stepper motor. A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage.

Therefore, the control gives the valve the command “open valve” in situations where the reference value is far lower than the actual value. The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. The first option is the fastest possible refrigeration.

The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.

To print the manual completely, please, download it. However, in this case, more time must be planned for achieving the required reference value.

And on the other danvoss, you can see immediately which values the control takes for granted. 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.

This sensor measures the actual value of the outlet air temperature of the evaporator and feeds this back to the controller. This is a good danfoes aid. In other words, you cannot see a status code, if there is an active alarm.

This means that this media temperature control can be integrated in complex Danfoss control system networks. Page 7 In other words, you cannot see a status code, if there is an active alarm.

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 12 Cut out NTC resistor in actuator. 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. Page of 16 Go. By pressing ‘print’ button you will print only current page. Precise media temperature control. The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting.

This system does not inlude any inner control loop. This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. In the case of electric defrosting, the “KVS” is opened. If the actual application has a requirement re- garding max.

Home page Service and support Case studies Precise media temperature control.

Page 13 If the actual application has a requirement re- garding max. Enter text from picture: 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. Don’t have an account? Digital controller for refrigeration and defrost, 3 relays pages.

Don’t show me this message again. Page 5 Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page Digital controller for refrigeration and defrost, 1 relay pages. Here it is dajfoss to eliminate even the smallest temperature changes so that the measuring results are not affected. After defrosting, the drip-off time begins.
