Danfoss KoolKey EKA 200 Installation Manual

Installation Guide
KoolKey
Type EKA 200
KoolKey is a gateway and programming device to:
• Connect the Danfoss electronic controller to a PC and act as a gateway when working online using
the KoolProg® application on the PC.
• Act as programming key to program parameter settings (configuration) into the Danfoss electronic
controllers in the production and field.
Supported controller types:
1. ERC 111, 112, 113
3. EETc 11, 12, 21, 22 & EETa 2W, 3W
Warning:
1. Ensure to disconnect non-isolated controllers (ERC 11X & EET) from mains power, before connecting to KoolKey.
2. Do not leave the interface cable hanging from powered-up controller.
KoolKey as a Gateway
Gateway mode makes it possible to work online with the connected
controller through KoolProg® on a PC.
KoolProg® allows following functions:
• Set Parameters – Create, view and edit controller settings.
• Copy to Controller – Program settings file created offline to the
connected controller.
• Online service – Monitor real time operations of the controllers and
make adjustments to the parameter settings while connected.
Connection:
• Connect the KoolKey using a standard USB cable to the USB port of
a PC installed with KoolProg® software
• Connect the controller to KoolKey other end using the interface cable
of the respective controller type
• The controller gets power from the PC via connected KoolKey
(Refer to the KoolProg® User Guide

KoolProg® as Programming Key
The programming key function is used for transferring parameter
settings files from the KoolKey to the controller and vice versa.
Transfer or copy the parameter file in below format to KoolKey like
any other storage device.
We recommend to save only the file intended for the target
controller.
a. Steps to program a powered-up controller:
1. Connect the KoolKey to the controller communication port (TTL/di
port) using an interface cable.
2. Power up the controller using 120 V/230 V power supply.
3. Move the slider switch to required position and short press (1 sec)
the start button to transfer data.
4. After successful data transfer, switch off the controller power
supply and remove the KoolKey.
Note: While programming EET compact (EETc) and EKF controllers,
KoolKey requires to be connected to a power source as mentioned in
Fig. 4.
b. Steps to program an unpowered controller
(write function only):
1. Connect a Power bank or a 5 V power supply to KoolKey USB port.
2. Connect the Koolkey to the controller's TTL/di port using an inter-
face cable.
3. Write function gets initiated as soon as the KoolKey is connected
to controller (no need to press the start button).
