Mounting Instructions
Tools and Fixings Required
4 x M5 Screws for securing ATOM Switch and Actuator.
• Screws must be suitable length for a minimum of 10mm thread engagement.
• Screws must be security type to prevent unauthorised removal or tampering, for example pin-hex or pin-torx anti-tamper
security screws.
• Minimum required screw type and class; 12.9 Grade High Tensile Steel to maintain FZH value.
- Note; F1max value was achieved using four 12.9 Grade High Tensile Steel M5 Cap Head bolts
• Required torque setting; 8-12 Nm.
4 x M5 Nut / T-Nut / Threaded Hole for securing ATOM Switch and Actuator.
Driver suitable for securing M5 xing screws.
Auxiliary Release Driver Bit (provided) to operate Auxiliary Release Function.
1/4” Driver to suit Auxiliary Release Driver Bit.
Adhesive Threadlocker to secure mounting xings from loosening due to vibration. Threadlocker must be ‘middle strength’
or greater.
For units with Escape Release (ER) ONLY – A drill and 30mm hole saw for inserting Escape Release (ER) feature
through the fence post.
Additional Tools required for ATOM with Escape Release (ER) only;
Drill with min. 21mm hole saw for cutting required hole through Gate/Door post for Escape Release housing.
Mechanical Mounting Instructions
1. Locate the ATOM Interlocking Device so that operation of the Auxiliary Release function, Escape Release function (if
applicable), Functional testing, Electrical testing, Scheduled Inspection and Maintenance and nal unit replacement are all
easily possible.
2. Operate the Auxiliary Release function to remove the ATOM Actuator from the ATOM Switch assembly. Note, this step is
not applicable for Power-to-Lock solenoid type devices.
3. For ATOM with Escape Release (ER) only – Remove Escape Release knob (see Fig.1) by unscrewing it anti-clockwise.
4. Prepare the Door/Gate of the guarded area by cutting any required holes or threads following the dimensions of Fig. 4 and
Figures 7-11.
5. For ATOM with Escape Release (ER) only – Drill a minimum 21mm hole in Door/Gate post to allow for Escape Release
housing. See Fig. 10 for required hole location.
• Note; ATOM with Escape Release (ER) suitable for door/gate post thickness up to 56mm. For anything greater than 56mm
an extension kit will be required, please contact Fortress for more information
6. Mount the ATOM Switch and ATOM Actuator assemblies to appropriate parts of the machine or guarding.
• The ATOM Actuator must be correctly aligned and oriented with the ATOM Switch as per the assembly dimensions of Fig.
9 and Fig. 11.
• All mounting surfaces should be at, stable and suitable of providing a minimum of 10mm M5 thread engagement or
sufcient support to either an M5 Nut or M5 T-Nut. See Fig.3 and Fig.4 for some mounting examples.
7. For ATOM with Escape Release (ER) only – Re-attach Escape Release knob (see Fig.1) by screwing it on clockwise.
• Note; the escape release knob must be secured against tampering, removal or loosening using adhesive thread locker.
8. Perform Mechanical Function tests before completing installation and commission. See Mechanical Function test section.
• Note; Lid assembly does not need to be removed during mounting. Removing the lid assembly may foul product IP level.
Mount the complete ATOM Interlocking Device only in the correctly assembled condition.
- The complete machine guarding installation must conform to all relevant design, construction and installation standards and
guidelines.
- Any gap around the perimeter of the machine and guarding when closed and locked (Safety Outputs High) must not exceed
the limits specied in BS 294 & BS 953.
- All xing screws used to mount the Device must be permanently prevented from removal. If mounting xings are visible, they
must be secured against removal by personnel using standard tools, manipulation and un-authorised or un-identiable
removal. If mounting xings are not visible or hidden, they must be secured against removal or loosening due to vibration. In
both cases, a middle strength adhesive threadlocker is required.
- The Device must not be used as a mechanical stop. Where applicable, precautions must be made to ensure the door or
gate of any guarded area has sufcient support and stops to prevent the impact on the Device.
