General Description
Chapter 1
Guardmaster TLSZ Overview
This Guardmaster® TLSZ guard locking switch functions by locking it
actuator, which prohibits the opening of a guard.
TLSZ uses radio frequency identification, RFID, coding to detect the
The
appropriate target.
This version of the Guardmaster TLSZ guard locking switch features OSSD
outputs. These outputs are enabled only when the actuator is locked and the RF
target is sensed.
This device is intended to be part of the safety-related control system of a
machine. Perform a risk assessment before installation to determine whether
the specifications of this device are suitable for all operational and
environmental characteristics of the machine. See
certification information and ratings.
Use nonremovable screws, bolts, or nuts to mount the switch and actuators. Do
not over torque the mounting hardware.
TLSZ guard locking switches are classified according to ISO 14119 as Type 4
switching devices. The RFID targets are classified as having a high level of
coding.

Measures are to be taken to minimize the need to defeat and to manage the use
and availability of spare RFID targets.

with Power to Lock switches, the switches immediately become unlocked
and the user may have access to the hazards.

General Considerations
Actuator/Target Mounting
The TLSZ guard locking switch is designed for use on guards that are engineered to
be rigid and without sag. The TLSZ uses radio frequency identification, RFID,
coding to detect the appropriate target.
Figure 2 shows the correct and incorrect ways to mount the target with the
actuator.
The TLSZ must only be used with the fully flexible actuator. The replacement
part number for the actuator is catalog number 440G-A27143.

Chapter 2 Installation
Allowable Approach Directions
The actuator and target must be always mounted as “close coupled” and can
approach the switch in any of the three entry slot positions that are shown in
Figure 3. Approach from the underside is not allowed, as the distance from the
target to the internal RF sensor is too far for reliable operation.
Figure 3 - Allowable Approach Direction
This approach requires
guide repositioning, see
page 14.

Manual Release
The manual release feature only applies to TLSZR (Power to Release) switch.
In some cases, you must manually release the locked actuator.
Figure 6 shows the two locations from which the actuator can be manually
released.
Remove the T20 Torx screw.
1.
2. To release the actuator, insert a small screwdriver or rod in the hole.
If power is applied to the switch when the actuator is released, the OSSD safety
outputs turn OFF and the switch goes to a faulted state with the status
indicator flashing red at 4 Hz. Power then has to be cycled to the switch to
return it to an operational state.

Figure 7 on page 14 shows an optional cover that is available only for the
TLSZR (Power to Release) switch. This cover has a lever that allows you to
manually unlock the actuator at any time. Rotate the lever 90° to unlock the
actuator.
If power is applied to the switch when the actuator is released, the OSSD safety
outputs turn OFF, and the switch goes to a faulted state with the status
indicator flashing red at 4 Hz. Power is then cycled to the switch to return it to
an operational state.

If a pair of TLSZ switches are mounted too close to each other, the two RF
fields could interact causing crosstalk. Cross talk results in nuisance faults.
An absolute minimum of 200 mm (8 in.) must be used to help achieve correct
operation.
The restriction also applies if a TLSZ switch is mounted close to the 440G-LZ
guard locking and the 440N-Z SensaGuard™ switches.
Guide Repositioning
The actuator guide can be repositioned to facilitate alignment of the actuator.
In steps 8…11, rotate the metal guide to allow the switch body to be fastened
flush to the mounting surface.

Installation Chapter 2
Steel Locking Bolts
The TLSZ is assembled in the factory with plastic pins that secure the actuator
guide. The plastic pins are rated for a holding force of 1500 N (337 lb). The
plastic pins must be replaced with the steel bolts to achieve a holding force of
2000 N (585 lb).
Figure 9 shows how to remove the cover to replace the blue
plastic pins with steel bolts.

Figure 10 shows the clearance requirements for the TLSZ. The switch must
not be used as a guard stop. You must provide a mechanical stop at least 1mm
(0.04 in.) away from the actuator guide. The actuator must be inserted within
4mm (0.16 in.) or less from the actuator guide to be sure it locks.

Chapter 2 Installation
As shown in Figure 11, the TLSZ has two slotted holes to facilitate
installation. The slots allow up to 8 mm (0.31 in.) of movement of the switch
body to achieve the proper clearance with the actuator.
1. Use the slotted holes for initial installation.
2. After alignment with the actuator, secure the switch body in place by
adding mounting hardware in the circular holes.
3. To attain the maximum holding force, replace the plastic pins with steel
screws inside the cover.

Connections
The TLSZ is only available with an 8-pin DC Micro M12 quick-disconnect
connector. Figure 14 and Table 3 show the pin assignments and their functions
and typical mating cordsets. Other cordsets are available at
DC Micro Cordsets
and Patchcords.

Replace symbol with 2 [2 m (6.56 ft)], 5 [5 m (16.4 ft)], 10 [10 m (32.8 ft)], 15 [15 m (49.2 ft)] 20 [20 m [65.62 ft)] or 30 [30 m
(98.4ft)] for standard cable lengths. The TLSZ has been tested to operate with up to 120 m (393.7 ft) of the mating cables.
The OSSD inputs are Safety A+ and Safety B+. These inputs can be pure
24VDC, or they can contain test pulses. The OSSD inputs allow the TLSZ
switches to be connected in-series while maintaining a high level of safety
performance.
The OSSD outputs are Safety A and Safety B. These outputs are 24V signals
that contain test pulses. The test pulses are used to detect short circuits to 24V,
to 0V and cross faults (from Safety A to Safety B). This description of the test
pulses is provided for informational purposes; you cannot modify them.
