Controller for temperature control - EKC 202
The controller is used for temperature control refrigeration appli-ances and cold room in supermarkets.
Control of defrost, fans, alarm and light
For front panel mounting
Anvendelse
Application
* The controller is used for temperature control refrigeration appli-ances and cold room in supermarkets
* Control of defrost, fans, alarm and light
* For front panel mounting
Principle
The controller contains a temperature control where the signal can be received from one temperature sensor.
The sensor is placed in the cold air flow after the evaporator or in the warm air flow just before the evaporator.
The controller controls the defrost with either natural defrost or electric defrost. Renewed cutin after defrost can be accomplished based on time or temperature.
A measurement of the defrost temperature can be obtained directly through the use of a defrost sensoro.
Two to four relays vwill cut the required functions in and out – the application determines which:
* Refrigeration (compressor or solenoid valve)
* Defrost
* Fan
* Alarm
* Light
The different applications are described on next page.
Advantages
* Integrated refrigeration-technical functions
* Defrost on demand in 1:1 systems
* Buttons and seal imbedded in the front
* IP65 density from the front panel
* Digital input for either:
* Door contact function with alarm
* Defrost start
* Start/stop of regulation
* Night operation
* Change-over between two temperature reference - Case cleaning function
* Instant programming via programming key
* HACCP
Factory calibration that will guarantee a better measuring accu-racy than stated in the standard EN 441-13 without subsequent calibration (Pt 1000 ohm sensor)
Extra module
* The controller can afterwards be fitted with an insertion module if the application requires it.
The controller has been prepared with plug, so the module simply has to be pushed in
- Battery and buzzer module
The module guarantees voltage to the controller if the supply voltage should drop out for
more than four hours. The clock function can thus be protected during a power failure.
- Data communication
If you require operation from a PC, a data communication module has to be placed in the controller.
