System Configuration and Functions
Upgrading F3SJ for Muting System
1. Remove the caps of the emitter and receiver.(driver comes with key cap for muting)
2. Install a muting lamp (external indicator) on either the emitter or the receiver.
3. Attach the key cap for muting to the emitter/receiver on which the muting lamp (external indicator) was
not installed.
Muting Sensor
The muting sensor is the sensor that is the trigger for temporarily disabling the F3SJ's safety functions.
Through-beam or retro-reflective photoelectric sensors, proximity sensors, or limit switches can be
used as muting sensors. (recommendation: OMRON E3Z series, E2E series(3-wire type), D4N
series)Use 3-wire type NPN output or N.O. type contact. Two-wire type sensor cannot be used.
Muting Lamp (External Indicator)
You may need a muting lamp depending on your application or as a result of a risk assessment. Before
determining the use of the muting lamp, check laws and regulations of the country or region where the
F3SJ-A is used and make sure of full compliance with them. For the muting lamp, use F39-A01P-
PAC, or a F39-JJ3N universal indicator cable and a commercially available external indicator. Enabling
external indicator output diagnosis function allows breakage and short circuit detection of external
indicator or muting lamp connected to the output.
