RS-485 adapter (EKA 206)
The RS-485 adapter (EKA 206) adapter allows to integrate the controller on a Modbus fieldbus. The controller is
supported by the following Danfoss front ends:
• AK-SM 720 system manager
• AK-SM 800 system manager
• AK-SM 800A system manager
The KoolKey (EKA 200) allows to connect the EKC controllers to the PC application named “KoolProg”. Via KoolProg it
is possible to perform on-line and off-line programming of the EKC controllers. It can also perform production line
programming of multiple controllers and show on-line trend curves on selected parameters.
Finally “KoolProg” can also load controller setup files into the MPK - Mass Programming Key (EKA 201) which can be
used for simple production line programming of EKC controllers.
