TLSZR/L-GD2 Guard Locking Switch
Installation Instructions
Installation must be in accordance with the following steps and stated specifications and
conducted by competent personnel. The unit is not to be used as a mechanical stop. Guard stops
and guides must be fitted. Adherence to the recommended maintenance instructions forms part
of the warranty.
This device is intended to be part of the safety-related control system of a machine. Before
installation, a risk assessment should be performed to determine whether the specifications of
this device are suitable for all foreseeable operational and environmental characteristics of the
machine to which it is to be fitted. See Technical Specifications for certification information and
ratings.
Use nonremovable screws, bolts, or nuts to mount the switch and actuators. Do not over torque
the mounting hardware.
For use with flexible actuator only, 440G-A27143.
TLS-Z 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.
IMPORTANT SAVE THESE INSTRUCTIONS FOR FUTURE USE
ATTENTION: Guard locking switches that are activated by the power to lock principle,
440G-TZS21UPLH, must only be used after a risk assessment has shown that the use of a power to
release principle, 440G-TZSPRH, is inappropriate, since the guard can be immediately opened
after a loss of the power supply or upon activation of the unlocking signal.

OSSD Outputs and Pulse Testing
The safety inputs are Safety A+ and Safety B+.
The OSSD outputs are Safety A and Safety B with the safe state defined as 0V (guard door open

Allowable Approach Directions
Clearance in Closed Position [mm (in)]
(and Maximum Actuator Insertion Distance for Locking)
Auxiliary/Manual Release [mm (in.)]
A manual release is possible by removing the secure TorX screws and pressing the internal
mechanism.
The actuator and target should always be
mounted as “close coupled” and can approach
the switch in any of the three entry slot
positions shown.
Approach from the underside is not allowed.
2...5 (0.08...0.20)
Provide a separate mechanical stop to protect the
switch.
Minimum clearance: 2 (0.08).
Maximum assured locking distance: 5 (0.20).
IMPORTANT Do not use the switch as a guard stop.

If power is supplied to the switch and the
switch is in the locked state, operation of
the auxiliary release will cause the switch to
enter a fault condition (blinking red
LED).
To reset the switch, cycle the power.

Rockwell Automation Publication 440G-IN007B-EN-P - September 2016 9
TLSZR/L-GD2 Guard Locking Switch
Minimum Operating Radius [mm (in.)]
Minimum operating radius is for all planes of approach of the actuator key, both along the length
and perpendicular to the key. Use the two adjusting setscrews on the actuator to optimize the key
angle.
Manual Override Key for Power-to-Release Version
The cover with manual override key is intended for use with a power-to-release version
TLSZR-GD2. It provides an auxiliary release function for use when power is not available to
achieve automatic/electrical interlocking.
Mounting Restrictions
If a pair of TLS-Z switches are mounted close to each other, the two inductive fields will interact
causing crosstalk, which will result in nuisance faults and false operation.
An absolute minimum of 200 mm (8 in.) must be used to help ensure correct operation.
The above applies if a TLS-Z switch is mounted close to the 440G-LZ guard locking and the
440N-Z SensaGuard™ switches.
