The BlueControl Extension Box 20RL (part number 136471) is a device designed to expand the I/O capabilities of SKOV A/S controllers, particularly when the standard hardware's I/O modules are insufficient. This technical user guide provides comprehensive instructions for its installation, connection, and maintenance.

Function Description:

The BlueControl Extension Box 20RL serves as an I/O expansion unit for SKOV A/S controllers. It includes two I/O modules, specifically type 3, 10RL 8AI 10RL. This configuration provides additional inputs and outputs to enhance the control system's capacity. The inputs can be individually configured using jumpers for various functions: DOL 12 (Digital Output Logic 12), DI (Digital Input) for devices like water meters, or AI (Analog Input, 0-10 V). The extension box is designed to integrate seamlessly with existing SKOV A/S controllers, allowing for a more extensive and flexible control setup. The controller's standard software and hardware support a total of 13 I/O modules, with the BlueControl Extension Box 20RL counting as two modules towards this total.

Usage Features:

The BlueControl Extension Box 20RL is designed for straightforward installation and integration with SKOV A/S controllers. It can be mounted to either the left or right of the main controller. The installation process involves knocking out designated pieces in the box and controller sides, mounting plastic glands in the bottom section, drilling holes for screws, and securing the cabinet to the wall. Horizontal alignment is crucial, and washers can be used to compensate for uneven wall surfaces. Rubber sleeves are included for cable routing.

Configuration of the I/O modules is achieved through jumper settings and rotary switches. The manual provides clear instructions for setting the OFF/ON jumpers on the I/O modules to assign addresses (Address = 1 for I/O module 1, Address = 2 for I/O module 2, Address = 3 for I/O module 3). Jumpers (A) and (B) allow for fine-tuning of input types (AI, DI, DOL 12) and emergency opening override for relays. The CAN protocol jumper (I) must be set as the main module, or to Classic if no jumper is present on the main module. Proper earthing of the extension box to the controller is also a critical step in the installation.

Maintenance Features:

Maintenance of the BlueControl Extension Box 20RL primarily involves cleaning and proper disposal.

Cleaning: The product should be cleaned with a cloth that has been wrung out almost dry in water. It is important to avoid using high-pressure cleaners, solvents, or corrosive/caustic agents, as these can damage the device.
Recycling/Disposal: Products suitable for recycling are marked with a pictogram. Customers are responsible for delivering these products to local collection sites or recycling stations in accordance with local instructions. The recycling station will then arrange for further transport to a certified plant for reuse, recovery, and recycling, ensuring environmentally responsible disposal.

All installation, servicing, and troubleshooting of electrical equipment must be performed by qualified personnel in compliance with national and international standards (e.g., EN 60204-1 and other applicable EU standards). A power supply isolator is required for each motor and power supply to ensure voltage-free work on the electrical equipment, though this isolator is not included with the extension box.
