General Description
Guardmaster 440G-LZ
Overview
This Guardmaster® 440G-LZ guard locking switch functions by extending a locking bolt from the switch through a hole in the actuator, which prohibits the opening of a guard.
The locking bolt drive mechanism and logic confirms that the locking bolt is allowed to extend only when the corresponding actuator is detected within range.
RFID coding detects the appropriate actuator.
This version of the Guardmaster 440G-LC guard locking switch features
OSSD outputs. These outputs are enabled only when the locking bolt is sensed in its extended position in the actuator, which happens only when the guard is both closed and locked.
The locking bolt drive mechanism uses a bi-stable solenoid. As a result, the switch consumes little electrical power, with peak currents occurring only briefly, upon start-up and after each movement of the locking bolt.
Because of its bi-stable drive, not only does the device consume minimal power, but it does not produce heat whether in its locked or unlocked condition.
Despite the bi-stable design of the locking bolt drive, the device logic and functionality are configured to replicate the functionality of a Power to Release or Power to Lock solenoid-operated switch (depending on type).

Safety Concept
Safety Standards Applied to the Guardmaster 440G-LZ
Guard Locking Switch
The Guardmaster® 440G-LZ satisfies applicable requirements in the following standards that are related to functional and machinery assembly:
• IEC 60947-5-1: 2003+A1: 2009
• IEC 60947-5-3: 1999/A: 2005
• IEC 61508:2010 SIL 3
• IEC 62061:2005 SIL 3
• EN ISO 13849-1:2008/AC: 2009 Performance Level e (PLe),
Category 4
• EN ISO 14119:2013
• UL 508 17 th
Edition dated 3/19/2013
Introduction
This section describes the safety Performance Level concept and explains how the Guardmaster 440G-LZ meets the requirements for SIL 3, Cat. 4, or
Performance Level “e” (PLe) applications.
Safety Certification
The Guardmaster 440G-LZ is certified for use in safety applications up to and including SIL 3 according to IEC 61508 and IEC 62061 with a proof interval of 20 years, Performance Level PLe, and Category 4 in compliance with ISO
13849-1.
Safety requirements are based on the standards applicable at the time of certification.
The TÜV Rheinland group has approved the Guardmaster 440G-LZ for use in safety-related applications where Performance Level “e” is required for the door position and lock monitor functions.
The 440G-LZ must be installed in accordance with the applicable regulation and standards.
While the 440G-LZ can be used for SIL 3, PLe, and Category 4 applications, the installer must comply with guard requirements (for example,
EN I
SO13854 and EN ISO 13857). And in some cases also minimum (safe) distance requirements (for example, EN ISO 13855).

Chapter 2
Safety Concept
ATTENTION: A risk assessment is required to prove that the selected switch can be used in the desired application. A function test of the system is necessary to validate that it works as expected.
Guard locking switches that are activated by the Power to Lock principle,
440G-LZS 21 **L*, must only be used after a risk assessment has shown that the use of a Power to Release principle, 440G-TZS1**R* is inappropriate. This assessment is necessary since the guard can be immediately opened after a loss of power supply or upon de-activation of the unlocking signal.
The installed system, including the safety control system and the means by which the machine stops, must achieve the needed safety performance. The
440G-LZ is one element in the safety system.
Additional guidance on guards, guard locking and guard interlock can be found in:
• EN ISO 12100
• EN ISO 13854
• EN ISO 13855
• EN ISO 13857
• EN ISO 14119
• EN ISO TR 24119
• EN ISO 14120
• Application-specific C-level standards

Installation and Wiring
General Considerations
The 440G-LZ guard locking switch is designed for use on guards that are engineered to be rigid without sag. A separately mounted latch (for example, magnetic or mechanical) and mechanical stop are required.
It can be used on Full Body Access guards that do not require escape release, emergency release, or remote release guards. It can also be used in any situation where the alignment tolerance falls within the stated specification.
Installation where metallic particles are present is not recommended and can result in the switch being inoperable. Particle build-up in the vicinity of the locking bolt will likely cause jamming of the locking bolt, which over time causes switch failure. Ferromagnetic metal particles are especially harmful as they are attracted to the permanent magnet at the tip of the locking bolt. Any particle build-up eventually causes seizing of the movement of the locking bolt, which results in switch failure and can be avoided. The correct installation is to mount the switch away from any source of metal particles. If the correct installation isn’t possible, preventative maintenance is performed periodically to keep the switch clean of metallic particles. Pay particular attention during installation to be sure that any drilling swarf is excluded from the vicinity of the switch.
Installation must be in accordance with the present manual and implemented by qualified personnel exclusively. The 440G-LZ guard locking switch is intended to be part of the safety-related control system of a machine. Before installation, a thorough risk assessment must be performed to determine whether the specifications of this device are suitable for all foreseeable operational and environmental characteristics of the application.
See the Specifications section of this manual. Use appropriate screws, bolts, or nuts that are fitted by tools to mount the switch and actuators to avoid tampering.
Do not over-torque the mounting hardware.
ATTENTION: F or the switch, actuator and actuator mounting bracket:
• Only use the designated mounting holes.
• Never drill or use to support other structures such as a conduit, cable ways, or other hardware.

Installation and Wiring
Pair Proximity
During installation, make sure that you observe the following restriction: you must maintain a minimum distance between each pair of switches you mount.
Make sure to maintain a minimum distance of 200 mm (8 in.) between any two switches and actuators, as indicated in the following illustration.
This restriction applies to both pairs of 440G-LZ switches and combinations of 440G-LZ switches with the TLS-Z guard locking switches and/or 440N-Z
SensaGuard™ noncontact safety switches. All of these devices use inductive field technology for sensing actuator proximity and RFID technology for actuator code identification. These technologies enable high precision operation while also meeting the requirements to prohibit actuator substitution with either low- or high-level coding as described in
EN I
SO 14119.
200 mm (7.87 in.) minimum
The distance of 200 mm (8 in.) is the closest proximity distance of a pair of switches. No red colored parts of the two switches can be closer than 200 mm
(7.87 in.) including actuators.
If the minimum proximity dimension is not observed, the inductive fields interact causing cross talk. Cross talk results in nuisance faults and false operation.

Mounting for Protection from Ingress of Liquids
The 440G-LZ is rated for IP69 in accordance with IEC 60529:192 +
A2:2013. This rating involves a short-term test that is made with high-pressure water jets at 80° C (176° F). The test is passed if no water enters the enclosure

Chapter 3
of the switch that contains the electrical components and the switch function is not impaired.
This rating does not promise protection from any liquids other than water and does not promise the mechanical longevity from continuous or frequent exposure.
However, the 440G-LZ is used in CIP (clean-in-place) applications by virtue of the following features.
• Stainless steel is used for all metal parts including the M12 quickdisconnect.
• The product plastics are resistant to most alkaline cleaners used in CIP.
• An internal nitrile-rolling lip seal guards the locking bolt, which extends and retracts during locking/unlocking.
To be sure of maximum longevity when exposed to CIP, it is recommended that the switch be mounted in the inverted position with the actuator at the bottom. This position allows liquids to drain away from the locking bolt. It is also recommended that the plug in the middle of the actuator is removed to improve drainage (see Removal of the Actuator Plug).
Removal of the Actuator Plug
This plug can be broken out from the actuator if a through-hole is required to avoid a food trap when mounted on the hazard side of a guard door.
Twist the plug with a screwdriver until it comes apart.
Mounting the Switch Body
Three M5 fasteners (not provided) are required for proper mounting to a rigid guard door frame.

Installation and Wiring
IMPORTANT If it is decided to use a standard thread-locking compound on the mounting screws of the switch body, the manufacturers specification can be checked.
Many standard thread-locking compounds attach the plastic feet of the switch body, which cause stress cracks. It is recommended to use cyanoacrylate-type thread-locking compounds.
Setting Actuator to Switch
Alignment

Actuator RFID Setting
Installation and Wiring
Chapter 3
Switches with Standard Coded Actuators
These switches are ready for use and need no special RFID setting.
Switches with Unique Coded Actuators
Before use, the switches must first “learn” a new RFID guard actuator. This task is not performed at the factory, as there are two possible methods:
• “Multi-time” learning: the switch can learn up to eight actuators consecutively.
• “One-time” learning: The switch learns one actuator only, for life, irreversibly.
The “one-time” learn method can be invoked at any time, not just during RFID setting. For example, the switch could “multi-time” (learn four different actuators consecutively), then complete a “one-time” learn process that would prohibit it from learning any additional actuators.
Learning the First “Multi-Time” Actuator
Connect the switch to 24V DC (see the wiring diagrams on page 21 ), and verify that the lock command is off.
The Status/Diagnostic status indicator blinks a number of times, which corresponds to the number of times a new actuator can be acquired (a total of eight times when the switch is new). Then it repeats, which indicates that the switch has yet to learn a new actuator.
The switch automatically starts the learn process as soon as an actuator is placed in the guard-closed position of the switch.

Learn Additional “Multi-time” Actuators
Mount the new actuator on the guard and repeat the process. Introduce the actuator to the switch as previously described. During program finalization, the status indicator blinks green a number of times, which corresponds to the number of remaining learnable actuators.
Note: Once a unique coded switch learns a new actuator, any previous actuator is no longer usable by that switch.

“One-time” Learning Process
Proceed as in the “multi-time” teach process that was previously described, with the following exception. At the final programming (last) stage, withdraw the actuator from the switch until the status indicator turns solid red. Then immediately reposition the actuator near the switch. This process must be executed within 15 seconds.
The status indicator blinks, then turns solid to indicate that the learning process is complete.

Prove Basic Lock Function
To prove basic lock function and to verify correct actuator alignment, it can be necessary to extend the locking bolt. Do not extend the locking bolt mechanically; you must proceed electrically. The following basic connections are required:
• Pin 2 (brown wire) must be connected to 24V DC
• Pin 7 (blue wire) must be connected to 0V (GND)
With a Power to Release switch, the locking bolt extends when the guard is shut and the actuator is aligned. Connect Pin 3 (green wire) to 24V DC to unlock the switch and withdraw the locking bolt.
If power is removed from a Power to Release switch in the locked position, the locking bolt remains in its extended position (switch locked). Use the manual auxiliary release to unlock the switch.
With a Power to Lock switch, connect pin 3 (green wire) to 24V DC to lock the switch (for example, extend the locking bolt). When you disconnect pin 3, it unlocks the switch.
If power is removed from a Power to Lock switch in the locked position, the switch unlocks.
In either type of lock, the locking bolt never extends in the absence of the actuator.
Functional Testing
A manual functional electric test must be made:
• After installation
• After any maintenance or change of component
• If the guard is used infrequently
– Less than once a month for SIL 3/PLe
– Less than once a year for SIL 2/PLd

Installation and Wiring
ATTENTION: During the functional test, be sure that there are no persons in the danger area and that the machine startup does not cause a hazard.
1. Be sure that the guard door is open.
2. Connect the 24V DC power to pin 2. The switch conducts a self-testing regime at the end of which the diagnostic indicator is solid red.
3. Test to be sure that the machine cannot start.
4. Be sure the lock control at pin 3 is set to 0V for PTR and 24V for PTL types.
5. Test again to be sure that the machine cannot start.
6. Close the guard door and then be sure that the guard is mechanically locked and the diagnostic indicator is solid green.
7. Test to be sure that the machine can start.
8. Change the lock control at pin 3V to 24V for PTR and 0V for PTL types.
9. Be sure the machine stops, the guard door is mechanically unlocked, and the machine cannot restart.

General fault. Cycle power to reset.
Auxiliary Out Function
The Auxiliary Out only changes state when the door is shut and locked, regardless of OSSD status.
Two types of auxiliary output are available.
Lock Status
Auxiliary output changes state when the lock is either unlocked or locked.
Since the 440G-LZ can only lock if the door or guard is closed, the auxiliary out function can also be used to annunciate door position status if the lock command is set to lock.
Door Proximity Status
• Auxiliary output changes state when the actuator is in proximity to the switch body.
• The proximity is such that the actuator is within 20 mm (0.79 in.)
(measured centerline of lock bolt to centerline of the hole in the actuator).
• Can be used for door position if a latch is fitted such that a guard or door is either open or fully closed.
Catalog codes for both types are explained in Appendix A, Specifications.

The OSSD outputs are semi-conductor PNP transistors and are safeguarded against over-temperature at the semi-conductor junction. They are rated at
0.2 A and don’t exceed the trip temperature unless the current significantly exceeds this rated value. This protection does not “trip out” the complete switch when it is exposed to ambient temperatures greater than 55°C (131°F).
It would only switch off the OSSDs and the indicator diagnostic would report a non-recoverable fault as shown by a slow red flash, 1 Hz (see Status/
Diagnostic indicator troubleshooting).

The Z (height) position is adjusted by sliding the actuator bracket up/down on the profile. If the setting gap is centered between the minimum of 0 mm and the maximum of 5 mm
(0.20 i n.), a tolerance to misalignment of ±2.5 mm
(0.10 in.) is achieved.

The Z position can be carefully selected to offset the anticipated door sag or door drop. Simultaneously, be sure that the alignment is such that it is not possible to lift the door up and off the locking bolt. Also make sure that there is no possibility that the actuator would collide with the switch when the guard door is being closed. It is essential to check the alignment periodically throughout the use of the guard locking switch.

The X and Y positions can be adjusted using spacers underneath the switch and appropriate selection of the three pairs of actuator bracket holes, once the bracket is centered.
The tolerance to misalignment is ±2.5 mm
(0.10 in.).
The Z position can be carefully selected to offset the anticipated door sag or door drop. Simultaneously, be sure that the alignment is such that it prohibits lifting the door up and off the locking bolt. Also check to be sure there is no possibility that the actuator would collide with the switch when closing the guard door. It is essential to check the alignment periodically throughout the use of the guard locking switch.
