TLSZR/L-GD2 Guard Locking Switch
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 is mounted close to each other, the two
inductive fields interact causing crosstalk, which results in nuisance
faults and false operation.
An absolute minimum of 200 mm (8 in.) must be used to help achieve
correct operation.
The restriction applies if a TLS-Z switch is mounted close to the
440G-LZ guard locking and the 440N-Z SensaGuard™ switches.
For Learn Process light-emitting diode error codes, see
Status/
Diagnostic LED Error Codes during the Learn Process on page 5
.
If there’s an internal fault, the switch disables the OSSD outputs. Safety
A and Safety B to the safe state 0V and the diagnostic output light-
emitting diode flashes red at 1 Hz or 4 Hz, depending on the fault.
Commissioning
Before use, the 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 switch can learn up to eight targets
consecutively
•
“One-Time” learn:
the switch can learn just one target, for life, non-
reversible*
– “One-Time” learn can be invoked at any time, not just at
commissioning. For example, the switch could “Multi-Time”
learn consecutively four different targets, and then complete a
“One-Time” learn that would help prevent it from learning any
more targets.

Non-recoverable fault: Cycle power.
IMPORTANT
During the learning process, the target and actuator must
always be inserted or withdrawn from the switch together in
their normal mounting configuration. If the target is
introduced or withdrawn without the actuator, or the actuator
is inserted without the target present, then it’s possible a non-
recoverable fault condition occurs (requiring you to power off-
on cycle).
