Actuator RFID Setting
Switches with standard coded actuators
These switches are ready for use and need no special RFID setting.
Switches with unique coded actuators
Before use, the switches must first “learn” a new RFID guard actuator. This
task is not performed at the factory, as there are two possible methods:
• “Multi-time” learning: the switch can learn up to eight actuators
consecutively.
• “One-time” learning: The switch learns one actuator only, for life,
irreversibly.
The “one-time” learning method may be invoked at any time, not just
during RFID setting. For example, the switch could “multi-time” learn four
different actuators consecutively, then complete a “one-time” learning
process that would prevent it from learning any additional actuators.
Learning the First “Multi-Time” Actuator
Connect the switch to 24V DC (see the wiring diagrams on page 21 ), and
ensure that the lock command is off.
The Status/Diagnostic LED will blink a number of times corresponding to
the number of times a new actuator may be acquired (a total of eight
times when the switch is new), then repeat, indicating that the switch has
yet to learn a new actuator.
The switch automatically starts the learning process as soon as an
actuator is placed in the guard-closed position of the switch.
ATTENTION: After installation, ensure
that there is no possibility of lifting the
actuator over the extended locking bolt.
ATTENTION: After installation, ensure
there is no possibility of collision when
the actuator approaches the switch body.
