The controller has been specially designed for refrigeration applications, but may of course also be used for other forms of regulation where this is expedient. The controller comes in several versions with a growing number of functions – from the simple one with just one relay to more advanced versions with three relays. All versions are furthermore available with an alarm function. The number of relays will then be increased by one.
The relays are used for controlling: This input will register the position of a connected switch and depending on the functions you want to use, it will work, as follows: The controller comes prepared with plug and terminals, so all you have to do is to push the module into place.
If you want to change the periodical defrost, so that it can be performed at specific times of the day, a clock module elc be fitted.
The module is provided with battery backup. Natural defrost on pump down. Natural defrost on compressor stop. Room temperature control by pump down. Temperature-controlled hot gas defrost. Time-controlled hot gas defrost. It will cut out again when the temperature drops to the set reference value. This function is ddanfoss when too long sensor cables have to be corrected. With these settings it will only be possible to set the reference between the two values. Alarm settings Alarm Settings The controller can give alarm in various situations.
If the controller is provided with an alarm relay, it will ec be activated. Upper deviation Here you set when the alarm at high temperature is to become activated. The value is set in K. A01 Upper deviation Lower deviation Here you set when the alarm at low temperature is to become activated. A02 Lower deviation Temperature alarm delay If one of the two limit values is exceeded, a timer function will star t.
The alarm will only become visible, when a set time delay has been passed. The time delay is set in minutes.
A04 Door alarm delay Reset alarm The function resets all alarms when set in pos. When the thermostat calls for refrigeration, the compressor relay will be cut in. Running time To prevent repeated stop-and-go operation, values can be set for how 210 the compressor is to run once it has been star ted.
And for how long ejc must at least be stopped. OFF-time Safety function in connection with sensor errors If the room sensor becomes defective is shor tcircuited or cut outthe controller will star t a regulating frequency of the compressor at the same time as an alarm is sounded for the sensor error.
Conversely, if the controller has not accomplished the 72 periods, the regulation will use a timeperiod of 20 minutes. During these 20 minutes the compressor will be star ted and stopped with this percentage setting. Defrost Defrost The controller contains a timer function, so that the defrost can star t periodically, e. If defrost is performed at cer tain times of the day, the setting must be made, so that it fits into this sequence; but the controller could also be provided with a module containing a real-time clock.
If this clock is mounted, defrost can be star ted at fixed times of the day. In controllers with a defrost relay you can set whether the defrost is to be made with electricity or hotgas. The actual defrost can be stopped based on time, or a temperature sensor may be placed on the evaporator, so that defrost can be stopped at a temperature value. Defrost method Here you set whether defrost is to be accomplished with electricity or hotgas.
During defrost the defrost relay will be cut in. The temperature value is set. If a defrost sensor has not been mounted, defrost will be stopped on time basis. Either you put the function in pos.
OFF or you set an inter val.
Controller for temperature control – EKC and EKC Manual |
Set it in pos OFF if you star t the defrost by means of input DI or if you mount a real-time Module in the controller. Here you simply set how often defrost is to be star ted. If you have chosen stop based on time, this setting will be the defrost time. The function is fur thermore only relevant if you have chosen defrost with interval star t d The function delays the defrost with the set number of minutes, but only for the very first defrost after energy has been supplied to the controller.
The time when water drips off the evaporator. Here you can set the value at which the fan may star t. Fan cut in during defrost Here you can set whether danfoss is to operate during defrost.

Defrost sensor Here you can set whether a defrost dangoss has been mounted. Here you set for how long the alarm is to dxnfoss suppressed. Here you set for how long the exact measuring is to be suppressed. During and immediately after a defrost the display will show the temperature measured just before defrost was star ted. The temperature at the defrost sensor is shown here.
Fan function Fan In addition to the fan functions concerning defrost the fans may also be stopped as a function of the compressor operation and a possible door function. Fan stopped at cut-out compressor Here you can select whether the fan is to be stopped when the compressor is cut out F01 Fan stp comp danfose Delay of fan stop when compressor is cut out If you have chosen to stop the fan when the compressor is cut out, you can delay the fan stop when the compressor has stopped.
Here you can set the time delay. F02 Fan del comp out Fan stop at open door If you have selected the DI-input for monitoring a door switch, you may also stop the fan when the door is registered open. Select yes or no for the function. A door switch is connected and the controller will register when the DI input is open.
When the time for door alarm A04 expires, a failsafe function will enter into force compressor and fan will be star ted. A switch function with spring return is connected.
Danfoss Electronic Controller (EKC EKC ) –
The controller dqnfoss register when the DI input is cut in. It will then star t a defrost cycle. It is also a must that each controller receives power from its own, separate power supply unit.
If a module with data communication is mounted, the controller can send the status of the switch function to the data communication network.
If not, you may cancel the function by means of setting OFF. When a PT sensor is used, the temperature will be shown with one decimal 0. If a PTC sensor is used, the temperature will be shown in whole figures 1.
ON, you reinstate the factor y-set values Factory setting If you need to reset the controller and reinstate the factor y-set values, do the following: Remove the power supply – keep both buttons down at the same time as you reconnect the power supply.
These settings can only be made when a data communication module has been mounted in the controller and the installation of rkc data communication cable has been concluded. When a data communication module is mounted, the controller may be fitted with a Danfoss gateway type AKA The operation of the controller can now be carried out via the data communication.
Real-time clock With this module you can set up to six individual times for defrost star ts per 24 hours. If you canfoss the top button in this situation, you will be able to see the alarm message in the display. There are two kinds of error repor ts – either an alarm occurring during the daily operation, or a defect in the installation.
Here is a list of the messages that can appear: High-temperature alarm A1 High temp. Shor tcircuited room sensor Ranfoss Air sensor s. Cut-out defrost sensor E4 Def.
Shor tcircuited defrost sensor E5 Def. A-alarms will only become visible when the set time delay has expired. Ealarms will however be visible as soon as the defect occurs. Alarm destinations The impor tance of the individual alarms can be danfpss by means of a setting 0, 1, 2 or 3. Push the uppermost button 1s briefly. If there is a status code it will be shown in the display.
They mean the following: When the compressor is operating, it must e,c for at least x minutes. When the compressor is stopped, it must remain stopped for at least x minutes. The evaporator is dripping off and waiting for the time to expire. Manual control 8 Manual RS. If the net frequency is 60 Hz there will be the following limitations: EKC12 V: You obtain it by pushing the top button for a couple of seconds -you will then enter into the row of parameter codes.
Find the parameter code you want to change and then push the two buttons simultaneously. When you have changed the value, save the new value by pushing the two buttons simultaneously once more.
