Fiber Connection
The E3X Amplifier Unit has a lock button for easy connection
of the Fiber Unit. Connect or disconnect the fibers using the
following procedures:
1. Connection
Open the protective cover and raise the lock lever to release
the lock. Next, insert the fibers according to the fiber insertion
marks on the side of the Amplifier Unit, and lower the lock
lever.

Note: Do not pull on, compress, or otherwise exert excessive force on the fibers
after connecting them to the Amplifier Unit. (Do not exert more than 0.3
N·m.)
Note: If one of the fibers from the Fiber Unit has a white line, such as with a Coaxial
Sensor, that fiber is for the Emitter. Insert it into the Emitter section. Refer to
Dimensions for the Fiber Unit to see if there is an Emitter fiber.
2. Disconnecting Fibers
Remove the protective cover and raise the lock lever to pull
out the fibers.

EEPROM Writing Error
If the data is not written to the EEPROM correctly due to a
power failure or static-electric noise, initialize the settings with
the keys on the Amplifier Unit. ERR/EEP will flash on the
display when a writing error has occurred.
Optical Communications
Several Amplifier Units can be slid together and used in
groups. Do not, however, slide the Amplifier Units or attempt
to remove any of the Amplifier Units during operation.

Protective Cover
Always keep the protective cover in place when using the
Amplifier Unit.

● Design Precautions
Applicable Fiber Units
Refer to the sensing distance tables on pages 5 to 7 for the
Fiber Units that can be used and the sensing distances.
Retro-reflective, Convergent-reflective, Ultra-compact, and
Application-specific Fiber Units, which are not listed, cannot
be used.
● Installation Precautions
Glossy Sensing Objects
If the sensing object is glossy, detection may not be stable. If
the Sensor is inclined by 5° to 20° when using a glossy
sensing object, as shown below, detection capabilities can be
increased and stable detection achieved.
E32-CC200 or other Fiber Unit
Note 1. To maintain the fiber properties, confirm that the lock is released before
removing the fibers.
2. Be sure to lock or unlock the lock button within an ambient temperature
range between −10°C and 40°C.
● Adjusting
Mutual Interference Protection Function
Light from other sensors can cause the value on the digital
display to become somewhat unstable. If this occurs, reduce
the threshold to create a greater margin and enable more
stable detection.
Output Short-circuits Protection
OVER/CUR will flash on the display if the output short-circuit
protection function operates due to a load short-circuit in a
control output. If this occurs, check the load connections.
