Commissioning; Multi-Time" Learn Process - Allen-Bradley TLSZR/L-GD Installation Instructions Manual

In the event of an internal fault, the switch will disable the OSSD outputs Safety A and Safety B
to the safe state 0V and the diagnostic output LED will flash 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 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 prevent it from learning any more targets.
During the learning process the target and actuator must always be inserted or withdrawn
IMPORTANT
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withdrawn without the actuator, or the actuator is inserted without the target present, then a
non-recoverable fault condition may occur (requiring a power off-on cycle).

"Multi-Time" Learn Process

Learning the first "Multi-Time" target
• Connect the switch to 24V DC (see wiring diagrams on pages 14 through 16).
The Status/Diagnostic LED will blink the number of times a new target may be learned (eight
times when new), and then repeat, indicating that the switch has not yet learned a target.
• The switch will automatically start the learning process as soon as a target and actuator are
placed into the door-closed, locked position of the switch
Leave the target/actuator in the door-closed position during the learning process. If they are
IMPORTANT
removed during the learning process, the ability to learn an additional target will be disabled.
The learning sequence as indicated by Status/Diagnostic LED:
• Target present:
• Verifying target:
• Programming switch:
• Programming finalizing:
• Ready state (learn is complete):
Learning additional new "Multi-Time" targets
Mount the new target to the door and repeat the above process, introducing the target and
actuator to the switch as described above. During programming finalizing, the LED will blink
