Danfoss EKA 163A / 164A Display Instructions

Product Overview

The Danfoss EKA 163A and EKA 164A are specialized display units designed for use with ADAP-KOOL controllers. The EKA 163A serves as a universal display, while the EKA 164A functions as a universal setting display, allowing for configuration and monitoring of refrigeration systems.

Technical Specifications and Installation

The units are designed for panel mounting. Ensure the installation environment meets the following temperature requirements:

• EKA 163A: Ambient temperature range of 0 to +55°C (non-condensing).
• EKA 164A: Ambient temperature range of -20 to +55°C (non-condensing).

The displays are connected to controllers using specific cables. For EKC 4xx, EKC 5xx, and AK series controllers, the maximum cable length is 15 meters. For other compatible controllers such as EKC 202D, 204A1, AK-CC 210/260, AK-CC 450/550, and EKD 316, the maximum cable length is 1000 meters.

Wiring and Communication

When connecting the displays to controllers, ensure correct wiring according to the specific controller model. Data communication settings must be configured as per the relevant literature (RC8AC). For network-based connections, ensure the address parameter (o03) is set to a value greater than 0. Proper termination is required for data communication lines to ensure signal integrity over long distances.

Maintenance and Disposal

The units do not require specific routine maintenance. However, ensure that the display surface remains clean and free of obstructions. This product contains electrical components and must not be disposed of with domestic waste. It must be collected separately as electrical and electronic waste in accordance with local and currently valid legislation.
