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.

This procedure can be avoided by looking at the service daanfoss here it can be seen immediately in case of doubt, double check with the thermometer whether the value is realistic. The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature.
Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing.
The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant. The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”.
Once these processes have finished, the refrigeration process is restarted. This is a good troubleshooting aid.
Precise media temperature control | Danfoss
Comments to this Manuals Your Name. Add to my manuals Add. 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. Therefore, the control gives the valve the command “open valve” in situations where the reference value danfiss far lower than the actual value. 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.
On the one hand, they can be read quickly, which saves the effort of measuring with the temperature gauge. If connection sizes larger than emc mm are required for the suction line, it is recommended that you implement a solution with a main valve. After defrosting, the drip-off time begins. A valve that is almost closed creates a high outlet ranfoss.
This can be danfos achieved with electronic suction throttle regulation or media temperature control. Different transient processes in fanfoss start-up phase Special attention must be paid to the start-up phase of regulation. However, there can also be situations in refrigeration plants where humidity is required. The individual status codes have the following meanings: Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.
This sensor measures the actual value of the outlet air temperature of the evaporator and feeds this back to the controller. It is always easy to readjust a system like this through the eliminated condensate quantity at the evaporator. A completely open valve ensures maximum refrigeration and therefore the lowest possible outlet temperature in the actual load situation.
Digital controller for refrigeration and defrost, 1 relay pages. Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point. Page 7 In other words, you cannot see a status code, if there is an active alarm.
In simple terms, the purpose of the drip-off time 3361 to drain off ice that has turned into water on the evaporator via the condensate drain. This valve is equipped with a stepper motor and is controlled by an electronic controller e.

In other words, you cannot see a status code, if there is an active alarm. Don’t have an account? 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. Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page Don’t show me this message again. If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm.
And on the other hand, you can see immediately which values the control takes for granted. Danfoss reserves the right to alter its products without notice. To print the manual completely, please, download it.
The first option is the fastest possible refrigeration. After defrosting has been initiated, its standard procedure must be defined by setting the control appropriately. Cut out NTC resistor in actuator.
Danfoss EKC 361 Electronic Regulator for Pilot Valve
If you need to return to the 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. Smart multipurpose refrigeration controller erc 21x series 36 pages.
Home page Service and support Case studies Precise media temperature control. Enter text from picture: Controller for operation of evaporator on water chiller 16 pages.
The controller is operated using two push buttons. Here it is important to eliminate even the smallest temperature changes so that the measuring results are not affected. This system does not inlude any inner control loop.
Page 12 Cut out NTC resistor in actuator. It is a direct operating and pressure independent valve for control- ling media temperatur. In applications such as this, constant nozzle air temperature from evaporators is the key to success. A fast-reacting temperature sensor e. The lowest occurring suction pressure will have a danfows t value which in turn indicates the value of the n02 setting. S according to entered setpoint.
