Product catalog summary

Safety-related Notes
The document emphasizes that electrical connections must be performed by qualified electricians, and transformers should comply with DIN EN 61558 / VDE 570 part 2-6 standards. Maintenance should only be conducted by qualified personnel to prevent injuries and damage. In the event of a power failure, motorised dampers close, which could pose hazards if not properly managed. Proper disposal of electronic equipment is necessary to avoid environmental harm.

Areas of Application
The BKSYS fire damper mini-controller manages up to 16 motorised fire dampers (24V AC/DC) or 32 with a limit switch. It can be expanded with up to three BKSYS-EM1 modules and supports potential-free inputs for external contacts and outputs for fault messages. Configuration is done via a PC program included with the BKSYS USB adapter.

System Components
Basic Module BKSYS-GM1: Supplies power to expansion modules and actuators, integrates smoke detectors, and logs data. It supports up to 4 fire dampers with spring return actuators or limit switches and can be expanded with up to 3 modules.
Expansion Module BKSYS-EM1: Connects wirelessly to the basic module and supports up to 4 fire dampers. It includes potential-free inputs and outputs, Duo LEDs for damper position, and test switches.
Transformer BKSYS-063 - 160: Supplies voltage to modules and actuators. A 63 VA transformer is needed for dampers with limit switches, and a 160 VA transformer for those with spring return actuators.

Configuration
Configuration parameters are set using the BKSYS-USB adapter and PC program. Parameters include date/time, fault input configuration for smoke detectors and ventilation, and power supply settings. The system logs functions like damper positions and runtime errors in a ring buffer, which can be exported.

Technical Data
The system operates at a rated voltage of 24 V AC/DC with a maximum current consumption of 3600 mA. It functions in ambient temperatures from 0° to +55°C and stores between -20° to +60°C, supporting a maximum humidity of 80% relative, non-condensing. The basic module dimensions are 160 x 106 x 90 mm.

Specifications
The document provides dimensions for components like the Modbus module BKSYS-MOD (90 x 106 x 90 mm) and the basic module BKSYS-GM1 (160 x 90 x 106 mm). It specifies cable cross-sections for wiring fire dampers and smoke detectors, emphasizing voltage drop considerations.

Connection of Field Modules
Fire dampers and smoke detectors are connected using a star topology, with specific cable cross-sections recommended for different types of fire dampers.

Assembly
The basic module BKSYS-GM1 and expansion modules BKSYS-EM1 are mounted on DIN rails and connected via Plug and Play. Power is supplied through the basic module, and connections must follow the provided diagrams.

Commissioning
The commissioning process involves connecting the basic module to a PC using a USB adapter, setting configuration parameters, and ensuring proper communication between modules. Various settings, such as alarm logic and power supply, are configured through the BKSYS software.

Terminal Assignment
Detailed terminal assignments are provided for both the basic and expansion modules, specifying connections for voltage inputs, fault inputs, and outputs.

Order Code and Specification Text
The document lists various components and accessories, including the basic and expansion modules, USB adapter, Modbus interface, and transformers. Specifications for each component are detailed, including their functions and dimensions.

Modbus Interface
The appendix provides detailed instructions for configuring the Modbus interface, including setting unique addresses, parity, and baud rate. Communication between the motherboard and Modbus board is explained, with LED indicators for status display.

Technical Overview
The document provides technical details about the BKSYS Modbus interface, specifically for a fire damper mini-controller. It includes information on Modbus requests, baud rate settings, LED indicators, and actual values of slave units.

Modbus Requests
A complete Modbus request consists of 4 to 256 bytes, transmitted individually in RTU mode. The request includes fields for slave address, function code, data, and CRC.

Baud Rate Settings
The baud rate is configured using DIP switches 5 to 8, with options ranging from 1200 to 57,600 bps.

LED Indicators
LED 1 indicates communication status between the BKSYS basic module and the Modbus board, while LED 2 indicates communication with the external Modbus client.

Actual Values Table
The document lists register addresses and corresponding parameters for various system components, such as device type, system time, and module states. Parameters include data types and authorization levels.

Enumerations
Enumerations are used for connector types, damper states, and test states, providing specific values and descriptions for each state.

Supported Modbus Function Codes
The document outlines supported function codes, including reading input registers and writing single or multiple registers, although some functions are currently without implementation.

Supported Modbus Error Codes
Error codes are provided for scenarios where the Modbus slave cannot process a request, detailing illegal function codes and addresses.
