Commissioning
Power the Sensor
Connect the sensor to 24V DC. See "Typical Wiring Diagram"
section for help.
The sensor can be commissioned to either have the ability to
learn another actuator or be locked for a one time learn only. See
“Teaching in the Actuator” section.
Teaching in the actuator (ability to learn an additional
actuator)
Quick Start
1. Power up the sensor and bring an actuator into the sensing
range.
2. Leave the actuator in the sensing field for two minutes or
longer.
3. Learn is complete.
Initially teaching in the actuator
The sensor will automatically start the learning process as soon as
an actuator is brought into the sensing range.
Learning Sequence
The sensor "Status/Diag" LED will begin to blink
Green eight times then repeat, indicating that
the sensor has not yet learned an actuator.
The sensor can learn a new actuator up to eight
times. The "Status/Diag" LED will blink the
number of actuators left that a sensor can learn.
The actuator must not be removed from the
sensing field during the learning procedure or
the ability to learn additional actuators will be
disabled.
1. Target present: "Status/Diag" LED blinking Green 1 Hz rate
2. Verifying actuator: "Status/Diag" LED blinking Green/RED 1 Hz rate (15sec)
3. Program sensor: "Status/Diag" LED blinking Green/RED 4 Hz rate (15sec)
4. Program complete: "Status/Diag" LED blinking Green (# of learns left) (15 sec)
5. Ready state: "Status/Diag" LED solid Green
6. Learn is complete
A sensor can be locked so it can not learn
another actuator; see teaching in the actuator
(one time learn only) section.

Initially teaching in the actuator
The sensor will automatically start the learning process as soon as
an actuator is brought into the sensing range.
Learning Sequence
During the Program Locking Stage, perform the following steps:
a. Remove the actuator from the sensing field, until the
"Status/Diag" LED changes to solid red.
b. Replace the actuator back into the sensing field and the
"Status/Diag" LED will continue blinking green (number of
learns remaining).
Learning a new actuator:
To learn a replacement actuator, bring the actuator to be taught
into the sensing range of the safety switch.
The learn sequence is the same as the sequence for
commissioning the first actuator.
A sensor can not re-learn a previously learned actuator or a
standard SensaGuard actuator.
The sensor will only recognize the most recently learned actuator.
Unique Coded Diagnostic:
Error codes for learning process. Repeat until the unit is power
cycled.
1. Target present: "Status/Diag" LED blinking Green 1 Hz rate
2. Verifying actuator: "Status/Diag" LED blinking Green/RED 1 Hz rate (15 sec)
3. Program Sensor: "Status/Diag" LED blinking Green/RED 4 Hz rate (15 sec)
4. Program Locking: "Status/Diag" LED blinking Green (# of learn left) (15 sec)
5. Ready state: "Status/Diag" LED solid green
6. Learn is complete
A sensor can be locked so it can not learn
another actuator by removing the actuator from
the sensing field during the 15 second "Program
Complete" sequence.
