Operating Instructions: Hygienic Guard Lock
Description
Fortress' HGL is a Hygienic Guard Lock that is a compact and
ultra-robust RFID high coded solenoid interlocking device. As
typical with products from Fortress, HGL is externally approved
and is suitable for applications up to PLe/Cat. 4. The stainless-
steel housing and high retention force make this product suited
for heavier industry applications where washdown procedures
are necessary.
High misalignment in the self-centering actuator covers
any movement and inaccuracy in hinged and sliding guard.
Additionally, the units' head element has an open design
manufactured in stainless steel to allow for easy cleanability.
Available in multiple hardware variants, the device can
be configured for applications where hazards persist after
machinery is powered off. Multiple units can also be connected
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.
Hygienic Design and 3-A RPSCQC Authorisation
The HGL Hygienic Guard Lock has been specifically designed for use in environments and applications
where regular wash down occurs and where hygiene and good sanitation are critical.
The HGL and the accompanying HGL-HM Hygienic Mounting kit are designed to minimise unnecessary voids
and apertures and also to limit all areas of metal to metal contact. Where apertures and voids do exist, such
as for the locking head portion of the HGL, a simple open design allows for maximum cleaning access and
inspection visibility.
The HGL and HGL-HM kit have been Third Party Verified against all relevant sanitary (hygienic) requirements
for design, materials and fabrication of ANSI/3-A 00-01-2018 and are authorised as part of the 3-A
CERTIFICATE 68
Replacement Parts and System Component Qualification Certificate (RPSCQC) Program.
Important:
Fortress' Hygienic Guard Interlock is designed for use according to the installation and operating instructions enclosed. It must be
installed by authorized 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.
Fortress Interlocks Ltd accepts no liability whatsoever for any situation arising from misuse or misapplication of the device.
The Device is not to be used as a Mains Isolator or Emergency Stop. The device must not be used as a mechanical stop.
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 is a component to be added to a permanent electrical installation meeting the requirements of the applicable standards and
regulations.
The Device meets the requirements of the standard ISO 14119 – Safety of machinery, interlocking devices associated with guards-
Principles for design and selection.
It is important that the correct version of this device is selected. If there is any requirement for an escape release element in the
product, then the releasing version must be used.
DO NOT LEAVE AUXILIARY RELEASE TOOL IN PLACE!
Always keep the auxiliary release tool and any spare actuators in a secure place, under management control, as it allows access to
areas that may contain hazards and may result in incorrect operation of some devices.
BEWARE OF FORESEEABLE MISUSE BY OPERATORS WANTING TO BYPASS SAFETY SYSTEMS. THE USER SHOULD
ASSESS THE RISKS AND MITIGATE AGAINST THEM. The installation and operation of the unit must take into account the
requirements of ISO 14119:2024, Clause 8 - Design to minimize the motivation to defeat.
Safety functions should be validated to ISO 13849-1 and/or evaluated in accordance with IEC 62061.

Closing and Locking The device is closed by inserting the HGL Actuator assembly into the upper head portion of the HGL Switch assembly (See Fig.2). Once inserted, the internal mechanism then locks the Actuator assembly into the HGL switch placing the Device into its Locked-State, the Safety Outputs turn on, and the Monitor Output turns off. - Page 7 Operating Instructions: Hygienic Guard Lock Figure 2: HGL Actuator and Switch assemblies ACTUATOR ENTRY BORE HGL SWITCH ASSEMBLY HGL ACTUATOR ASSEMBLY LED INDICATION Figure 3: Auxiliary Release Function AUXILIARY RELEASE NOT OPERATED.

Page 11: Maintenance And Inspection
For best results it is recommended to clean the Switch assembly and Actuator separately. No further disassembly or dismantling of the HGL product is required. Any attempt to remove the lid or disassemble either the HGL Actuator assembly or Switch assembly will void the product warranty and potentially compromise the product functionality. - Page 12 Operating Instructions: Hygienic Guard Lock Figure 6: Dimensional Drawing – HGL Actuator Assembly Figure 7: Dimensional Drawing – HGL Switch and Actuator Assembly Disposal The device does not contain any certified hazardous materials so should be disposed of as industrial waste.
