Door Interrupt System with FYQLA1-140R-3 Logic Amplifier
Guided relays
The door interrupt system incorporates two force-guided safety relays that are
monitored for proper operation and generate a redundant output for application
use.
Input devices
Magnetic switches
The 50FY41 series hall effect door switches are a noncontact, magnetic actuation
system consisting of a sensor and a magnetically keyed actuator. The sensor
contains two hall-effect integrated circuits that are connected independently.
When exposed to this magnetic actuator and properly aligned, the sensor
responds with an output.
Approved devices
•
50FY41 series
Hall effect door interrupt sensor
•
52FY31 series
Keyed hall effect magnetic-actuator
NOTE:
These are the only approved devices that should be used.
50FY41 sensor alignment
Ensure the alignment of the sensor and magnetic actuator are correct
for proper operation. A 10 mm (0.39 in) separation distance between
sensor and actuator will cause an OFF condition, independent of axial
offset distance.
Cable length
Sensor cable length must not exceed 25 m (80 ft).
