Door Interrupt System with FYQLA1-140R-3 Logic Amplier
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 eect door switches are a noncontact, magnetic actuation
system consisting of a sensor and a magnetically keyed actuator. The sensor
contains two hall-eect 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 eect door interrupt sensor
• 52FY31 series Keyed hall eect 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
oset distance.
Cable length
Sensor cable length must not exceed 25 m (80 ft).
