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.

If the actual application has a requirement re- garding max. In the case of electric defrosting, the “KVS” is opened. By pressing ‘print’ button you will print only current page. This is a good troubleshooting aid.
Defrosting The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. For safety, a maximum defrost duration can also be set in the refrigeration controller, which ends the defrosting process in the case of a defective defrost sensor or a similar fault.
Precise media temperature control
Precise media temperature control. Different transient processes in the start-up phase Special attention must be paid to the start-up phase canfoss regulation. Page 7 In other words, you cannot see a status code, if there is an active alarm.
Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. 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. The “EKC ” also offers the option of defrosting regulation by external initiation through an input contact. If more than kohm is measured across terminals 17 and 18 disassemble the Actuator feels warm.
This can be done using special software type “Danfoss AKM”. A fast-reacting temperature sensor e. The controller is operated using two push buttons. This heating closes and opens the valve. In the case of this setting, a very clear undershooting of the outlet temperature of the evaporator is to be expected to facilitate fast refrigeration and ensure the reference temperature is quickly achieved. The lowest occurring suction pressure will have a belonging t value which in turn indicates the value of the n02 setting.

However, applications in the food industry are also possible. Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves fanfoss page P control involves standard regulation according to the deviation example: 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 dafoss can be completely programmed using these two buttons combined with a three-digit display where all important data is displayed. In applications such as this, constant nozzle air temperature from evaporators is the key to success.
This means that this media temperature control can be integrated in complex Danfoss control system networks. 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.
Here it is important to eliminate even the smallest temperature changes so that the measuring results are not affected. Either can be necessary. Operation The controller is operated using two push buttons.
However, in this case, more time must be planned for achieving the danofss reference value. On the one hand, they can be read quickly, which saves the effort of measuring with the temperature gauge.
The “NTC” resistor sends the control confirmation of the degree of opening of the valve via the inner actuator temperature. Danfosw text from picture: Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided.
In other words, you cannot see a status code, if there is an active elc. Got it, continue to print. In the case of hot gas defrosting, the “KVS” valve closes during the defrosting procedure.
Due to tolerances in the actuator, the setting value must be 10 K lower than shown in the curve. Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point. Remote service is also possible for this control system. 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.
