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.

Home page Service and support Case studies Precise media temperature control. The controller is operated using two push buttons. The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided. Don’t show me this message again.
The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting. Page 6 When you change the setting to an other language you must activate o04 before “the danfosss language” can be visible from the AKM program.
In applications such as this, constant danfoxs air temperature from evaporators is the key to success. It is always easy to readjust a system like this through the eliminated condensate quantity at the evaporator.
And on the other hand, you can see immediately which values the control takes for granted. By pressing ‘print’ button you will print only current page. 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.
Refrigeration specialists know that the danfoxs of “humidity” plays an important role in refrigeration, especially where unpackaged goods, meat, vegetables and fruit are concerned. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
If the actual application has a requirement re- garding max. P danfosa involves standard regulation according to the deviation example: Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page However, in this case, more time must be planned for achieving the required reference value. Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation.
This means that this media temperature control can be integrated in complex Danfoss control system networks.
The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”. Operation The controller is operated using two push buttons.
It is a direct operating and pressure independent valve for control- ling media temperatur. If you need to return to the factory-set values, it can be done in this way: Precise media temperature control. In the case of this setting, a very clear undershooting of the outlet temperature of the evaporator vanfoss to be expected to facilitate fast refrigeration and ensure the reference temperature is quickly achieved. Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing.
dandoss A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage. Once these processes have finished, the refrigeration process is restarted.
Suction line installation In the case of a media temperature control for refrigerating plants with a pipe size of up to danfosa 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.
Precise media temperature control
Page 12 Cut out NTC resistor in actuator. 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.
Digital controller for refrigeration and defrost, 3 relays pages. Service The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant.

The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. This control mode canfoss particularly advisable if the system is operated with external reference value changes, e.
Page 7 In other words, you cannot see a status code, if there is an active alarm. Solution for dandoss 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. Controller for operation of evaporator on water chiller 16 pages. Enter text from picture: 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.
Page 13 If the actual application has a requirement re- garding max. Of course, it is also the case here that the dew point for dehumidification must always be undershot.
A fast-reacting temperature sensor e.
