How to attach mounting bracket (F39-L19/L20)
To fully utilize the performance of
sensors, locate the F39-L19/L20
mounting brackets in the number sat-
isfying the dimensions "A" and "B" in
the sensor longitudinal direction.
• For the F39-L19
Spacing "A": 670 mm max.
• For the F39-L20
Spacing "B": 400 mm max.
Note: When installing sensors at locations
susceptible to vibration and shock,
increase the number of mounting
brackets.

The Interlock selection input line or the reset input line is not wired correctly or became
open.
Relay contact is welded. Releasing time of the relay takes too long.
The EDM input line is not wired correctly or became open.
Communication line (RS-485) is not wired correctly, became open, or causes other
errors.
One of the OSSD outputs is shorted or is not wired correctly.
Other failure in OSSD outputs.
Mutual interference. Interference light is received.
Types of the receiver and emitter are not the same.
Numbers of the receiver and emitter connected in series are not the same.
External noise. Internal hardware failure of the receiver or the emitter.
