Installation of the TLSZR/L-GD2 Guard Locking Safety Switch must be in
accordance with the following steps and stated specifications, and implemented
by suitably competent personnel. Do not use the unit as a mechanical stop. You
must fit guard stops and guides.
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. 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.
Specifications
IMPORTANT Do not attempt to install this device unless the installation
instructions have been studied and understood.
IMPORTANT Save these instructions for future use.

ATTENTION: Perform a risk assessment. Only use safety
switches that the Power to Lock principle activates (catalog
numbers 440G-TZS21UPLH and 440G-TZS21UTLH), if the risk
assessment shows the Power to Release principle (catalog
number 440G-TZS21UPRH and 440G-TZS21UTRH) is
inappropriate. This distinction is because the guard can
immediately open after a loss of the power supply or upon
activation of the unlocking signal.

TLSZR/L-GD2 Guard Locking Switch (Series F) Installation Instructions
Figure 4 - Auxiliary/Manual Release [mm (in.)]
When the safety switch has power and is in the Locked state, operation of the
auxiliary release causes the safety switch to enter a fault condition (the status
indicator flashes red).
To reset the safety switch, cycle the power.
To manually release the safety switch, remove the secure Torx screws and press
the internal mechanism.
Figure 5 - Actuator Minimum Operating Radius [mm (in.)]
The 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 setscrews on the
actuator to optimize the key angle.
Figure 6 - Fit the Override Covers (Cat. No. TLSZR-GD2)
The cover with manual override key provides an auxiliary release function for use
when power is not available to achieve automatic/electrical interlocking.
Mount Restrictions
If you mount a TLS-Z safety switch close to another safety switch, a 440G-LZ guard
locking switch, or a 440N-Z SensaGuard™ switch, the two inductive fields interact
causing crosstalk, which results in nuisance faults and false operation. For correct
operations, maintain a minimum distance of 75 mm (3 in.) between safety
switches.
Commissioning
Before use, the safety switch must first learn a new RFID door target. This step is
not done at the factory, as there are two options:
• Multi-time learn: The safety switch can learn up to eight targets
consecutively
• One-time learn: The safety switch can learn just one target, for life,
non-reversible.
You can perform a one-time learn at any time. For example, the safety
switch can multi-time learn consecutively four different targets, and then
complete a one-time learn to help prevent the safety switch from learning
any more targets.
Multi-time Learn Process
Learn the First Multi-time Target
• Connect the safety switch to 24V DC (see Wiring Diagrams on page 6). The
status/diagnostic indicator flashes the number of times the safety switch
can learn a new target (eight times when new). The flash repeats, which
indicates that the safety switch has not yet learned a target.
• The safety switch automatically starts the learn process once a target and
actuator are placed into the door-closed and locked position of the safety
switch.
Learn Additional New Multi-time Targets
Mount the new target to the door and repeat Learn the First Multi-time Target on
page 3. While finalizing the program, the status indicator flashes green the number
of learns that remain.
One-time Learn Process
• Follow the Multi-time Learn Process on page 3 except at step 6 of the
learning sequence, withdraw the target and actuator from the safety
switch until the status indicator shows steady red. Then replace the target
and actuator back to the safety switch. You must complete this action
within 15 s.
• The status indicator flashes and then turns solid as usual to indicate that
learn is complete.

IMPORTANT During the learning process, insert and withdraw the target
and actuator from the safety switch together in their
normal mounting configuration. If you introduce or
withdraw either the target or actuator without the other
present, a nonrecoverable fault condition can occur. You
must then cycle power.
IMPORTANT After installation and commissioning, coat the actuator,
safety switch, and safety switch lid fixing screws with
tamper evident varnish or similar compound.
IMPORTANT Leave the target/actuator unit in the door-closed position
during the learning process. If you remove the unit during
the learning process, the ability to learn an additional
target is disabled.

TLSZR/L-GD2 Guard Locking Switch (Series F) Installation Instructions
Functional Testing
Perform a manual functional electric test:
• After installation
• After any maintenance or change of component
• If you use the guard infrequently
- Less than once per month for SIL 3/PLe
- Less than once per year for SIL 2/PLd
1. Confirm that the guard door is open.
2. Connect the 24V DC power to pin 2. The safety switch conducts a self-
testing regime at the end of which the status indicator shows steady red.
3. Test to confirm that the machine cannot start.
4. Confirm the lock control at pin 3 is set to 0V for PTR and 24V for PTL types.
5. Test again to confirm that the machine cannot start.
6. Close the guard door and then confirm that the guard is mechanically
locked and the status indicator shows steady green.
7. Test to confirm that the machine can now start.
8. Change the lock control at pin 3 to 24V for PTR and 0V for PTL types.
9. Confirm the machine stops, the guard door is mechanically unlocked, and
the machine cannot restart.
Maintenance
Weekly:
• Check for signs of abuse or interference.
• Check for missing screws, particularly for the manual release, which can
indicate abuse or interference.
• Check for damage, which can cause loss of sealing at the lid or conduit
entry.
Repair
If there is any malfunction or damage, do not attempt to repair or dismantle the
unit. Replace the unit before you allow machine operation.
Diagnostic
If an internal fault occurs, the safety switch disables the OSSD outputs. Safety A
and Safety B to the safe state 0V and the status indicator flashes red at 1 Hz or 4
Hz, depending on the fault.
Wiring
Auxiliary Out Function
Lock and door position status are available for auxiliary output.
Lock status (catalog numbers 440G-TZS21UPRH and 440G-TZS21UPLH): Auxiliary
output changes state when the lock either unlocks or locks independent of the
OSSD status.
Door position status (catalog numbers 440G-TZS21UTRH and 440G-TZS21UTLH):
Auxiliary output changes state when you either insert or with draw the actuator
key. If the auxiliary output is high (24V), the safety switch can lock and an internal
microswitch senses the position of the actuator.

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 or not locked).
Individual Pulses
Test pulses appear on each OSSD output. These pulses are approximately every
45 ms. The times that are shown are approximate and depend on the processing of
the safety-related status.
