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.

These values provide information about the state of the plant. Different transient processes in the start-up phase Special attention must be paid to the start-up phase of regulation. Don’t show me this message again.
Remote service is also possible for this control system. This valve is equipped with a stepper motor and is danfsos by an electronic controller e.
Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page And on the other hand, you can see immediately which values the control takes for granted. A valve that is almost closed creates a high outlet temperature.
Danfoss EKC 361 User Manual
Page 13 If the actual application has a requirement damfoss garding max. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
The service menu of ekd electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant. A system like this is suitable for ventilation and comfort air conditioning plants and conditioning cabinets, as well as for fruit and vegetable storage.
B – Product specifications
The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided. In the control menu, not only are basic adjustable values displayed, but it is also possible to precisely influence certain events by adjusting stability and amplification factors.
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.
This is an advantage, particularly where the release of high pressure and, if necessary, liquid in the evaporator are concerned. Either can be necessary. Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point.
Danfoss EKC 361 Electronic Regulator for Pilot Valve
Got it, continue to print. This system does not inlude any inner control loop. The second option only allows slight undershooting.
This heating closes and opens the valve. If the actual application has a requirement re- garding max.
If connection sizes larger than 54 mm are required for the suction line, it is recommended dxnfoss you implement a solution with a main valve. Add to my manuals Add. The actual value of this actuator temperature and the current reference value can be read in the control menu of “EKC ” “”.
Page 4 S according to entered setpoint. The controller 3611 be completely programmed using these two buttons combined with a three-digit display where sanfoss important data is displayed.
Page 11 The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting. The last option is to completely eliminate outlet values below the reference value during the start-up phase.
This control mode is particularly ekv if the system is operated with external reference value changes, e. Due to tolerances in the actuator, the setting value must be 10 K lower than shown in the curve. Page 8 If you need to return to the factory-set values, it can be done in this way: 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.
A fast-reacting temperature sensor e. The “EKC ” control has three different transient processes available. Xanfoss reserves the right to alter its products without notice. Here it is important to eliminate even the smallest temperature changes so that the measuring results are not affected. The “D component” in PID ddanfoss also optimises the control characteristics in danfose case of a sudden change to the reference value. The individual status codes have the following meanings: This means that any fitter at the plant can intervene in the control circuit and view relevant data.
S according to entered setpoint. Cut out NTC resistor in actuator. Furthermore, it is not necessary to fit an additional valve in the suction line since the dandoss can also be used for this shut-off function. For this purpose, indirect measures are normally taken, such as changing the evaporator fan levels or the evaporator speed i. It is a direct operating and pressure independent valve for control- ling media temperatur. In other words, you cannot see a status code, if there is an active alarm.
Danfos the one hand, they can be read quickly, which saves the effort of measuring with the temperature gauge. This means that this media temperature control can be integrated in complex Danfoss control system networks.
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.
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. Digital controller for refrigeration and defrost, 1 relay pages.
Controller for control of industrial evaporator 16 pages. Page 12 Cut out NTC resistor in actuator. It is possible to equip the control with a LON kec and record the appropriate data using a master unit and to intervene in the control system remotely using a modem connection. This also applies to products already on order provided that such alternations can be made without subsequential changes being necessary in specifications already agreed.
The “NTC” resistor sends the ek confirmation of the degree of opening of the valve via the inner actuator temperature.
