Operating Instructions: ATOM
Description
ATOM is a compact, ultra-robust, RFID, interlocking device
with a high-level coded actuator. As typical with products
from Fortress Interlocks, ATOM is externally approved and
is suitable for applications up to PLe (Cat. 4). The metal
housing and high retention force then suits ATOM for heavier
industry applications.
The self-centering actuator allows for inaccuracy and
misalignment in moveable guards, both hinged and sliding.
Additionally, ATOM’s head has an open design manufactured
in stainless steel to prevent dust, dirt and corrosion from
impacting performance.
Available in multiple hardware variants, the device can be
configured for many applications. Multiple units can also be
connected together with OSSD (Output Signal Switching
Device) functionality preventing fault masking. The large
LED lens at the base provides clear state indication from all
angles and at a distance.
An Escape Release (ER) option is available for Safety-on-
guard-Locking (SOGL) variants.
Important:
The ATOM interlocking device (The Device) is designed for use according to the installation and operating instructions
enclosed. It must be installed by competent and qualified personnel who have read and understood the whole of this
document prior to commencing installation.
If the device is used in a manner not specified by the manufacturer, the protection provided by the device may be impaired.
Any modification to the device or deviation from these instructions invalidates all warranties.
The Device must be installed in electrical installations meeting the requirements of the applicable IEC standards.
The Device is not to be used as a Mains Isolator or Emergency Stop.
The Device is a component to be added to a permanent electrical installation meeting the requirements of the applicable IEC/
EN standards.
All the voltages used within the connected circuits must be derived from a Safety Extra Low Voltage or Protected Extra Low
Voltage power supply (SELV or PELV).
The device contains a single electrical circuit; all inputs outputs and power supply have a common voltage reference, 0V.
The Device meets the requirements of the standard ISO 14119 – Safety of machinery, interlocking devices associated with
guards. Principles for design and selection.
DO NOT LEAVE AUXILIARY RELEASE DRIVER BIT IN PLACE!
Access to the Auxiliary Release Driver Bit and the availability of any spare ATOM Actuator assemblies must be securely
controlled as they could make it possible to bypass the safety Devices and allow access to areas that may have a residual
hazard.
BEWARE OF INTENTIONAL MISUSE CAUSED BY OPERATORS WANTING TO BYPASS SAFETY SYSTEMS.
THE INSTALLER SHOULD ASSESS THE RISKS AND MITIGATE AGAINST THEM.
The installation and operation of the ATOM device must take into account the requirements of ISO 14119, in particular Section
7 - Design for minimising defeat possibilities.
In order to maintain device safety rating, overall system must be validated to BS ISO 13849-2 and/or evaluated in accordance
with BS 62061.
