Danfoss Electronic Controller (EKC 201 EKC 301)

EKC 201 (for panel mounting) and EKC 301 (for DIN-rail mounting) have been specially developed for control duties in refrigeration plant so that operation, setting and programming are optimised and simplified as much as possible.

All controllers are designed for room temperature control via pump down or compressor start/stop and have been grouped into four main applications dependent on the type of defrost and its control.
EKC 201 and 301 are used for
Temperature control
Compressor control
Fan motor control
Defrost control
Alarm signalling

With only two keys, all functions can be set and programmed.
The display shows the actual room temperature, but by activating the keys the display changes
To the set or the actual temperature of the defrost sensor.

Fitting the EKC controller with a plug-in module for communication gives access to all parameters of the controller. Thus, EKC 201/301 can be included in the ADAP-KOOL® Refrigeration control systems.

The digital input can be programmed to
- receive alarm signals from an external signal source (door alarm)
- start defrost from an external clock
- transmit random alarm signals to the bus system.
Features
One electronic controller is able to replace several traditional controllers and defrost clocks.
Can be supplied for panel as well as DIN-rail mounting.
Temperatures, times, operating conditions, parameter codes and alarm and fault codes
Can be read from the display.
Three LEDs indicate the actual condition of the system:
- refrigeration
- defrost
- fan running.

Easy to re-establish factory setting.
In the event of error function, the actual parameter code can be displayed.
All alarms are indicated by the three LEDs flashing at once.
Danfoss Pt 1000 sensors are supplied with the controller:
- calibration of sensor circuit not necessary
- controller-sensor system can be used direct for data logging.
Facility for bus communication with SCADA system.

Real time clock (battery driven) can be fitted.
