The Euchner door box complete module MGB-L1H-ARA-L-110614 is an integrated command and signalling device for use in industrial safety systems. It serves as an interlock with interlock monitoring in accordance with standard EN 1088 and enables the safe control of machines or systems via a mechanical lock. The device is specifically designed for installation in door boxes and features integrated operating and indicator elements that ensure clear signal transmission. It is designed for use in safety-critical applications, where the reliability of the interlock and monitoring of the lock status are essential.

Applications
This module is used in industrial automation, particularly in systems that must comply with EN 1088 requirements for interlocks with monitoring. Typical application scenarios include machines with moving parts, where access must be locked during operation. The interlock ensures that the machine can only be started when the protective cover is properly closed. The device is suitable for use in production systems, manufacturing machines, and other industrial environments where safe operation and accident prevention are required.

Functions and Equipment in Detail
The module features two illuminated pushbuttons serving as operating elements. These buttons enable machine control, with the illumination visually indicating the operating status. Additionally, an emergency stop element is integrated, designed in accordance with ISO 13850. This emergency stop allows for immediate and safe shutdown of the machine in an emergency. The integrated indicator elements support visual feedback on the operating status. The device is equipped with a label carrier that can be glued into pre-moulded recesses. The standard size of the label carrier is 12.5 x 27 mm, ensuring uniform labelling of the operating elements.

Technology Explained Simply
The interlock monitors the lock status of the door box and ensures that the machine can only be switched on when the protective cover is fully closed. Monitoring is performed in accordance with EN 1088, guaranteeing a high safety level. The integrated operating elements, consisting of two illuminated pushbuttons and an emergency stop, enable intuitive operation. The illumination of the buttons provides visual feedback on whether the machine is activated or deactivated. The emergency stop, designed according to ISO 13850, enables immediate and safe shutdown regardless of the machine’s current operating status. The RC18 connector enables a simple and reliable electrical connection.

Compatibility and Accessories
The module is designed for series connection with other devices from the AR series, such as CES-AR or CET-AR. This series connection allows for expansion of safety functions and integration into larger safety concepts. The use of RC18 connectors ensures a standardised and reliable connection. Compatibility with other AR devices enables flexible adaptation to different requirements in industrial automation.

Installation and Mounting
The door box complete module is designed for installation in door boxes. Mounting is performed by inserting the module into the designated opening of the door box, ensuring the mechanical interlock is securely locked. The electrical connection is made via the RC18 connector, enabling a simple and secure connection. Labelling is done by gluing the included label carrier into the pre-moulded recesses. The standard size of the label carrier is 12.5 x 27 mm, ensuring uniform labelling.
