Connection
Do not pull the Fiber Unit with force exceeding 9.8 N or press the
Fiber
Unit with force exceeding 29.4 N.
The
fiber is so thin that the utmost attention will be required to handle
the
fiber
.
Do
not
bend the Fiber Unit beyond the permissible bending radius
provided
in
Ratings/Characteristics.
Do not bend the end of the Fiber Unit.

Mounting
When
Sensors are mounted to face each
other
, make sure to adjust
the
optical axes so that the Sensors will not be mutually interfered.
Installation
Power
Reset T
ime
The
E3MC is ready to sense objects from 100 ms after the E3MC is
turned ON, until when no devices connected the E3MC can be
used.
Be sure to
turn ON the E3MC first if power is supplied to the
E3MC
and the load independently
.
When
the E3MC is
turned ON or OFF
, the operation indicator will be
ON
for an instant but no control output will be turned ON.
When
using the Sensor for fine sensing, allow the system to
warm
up
for approximately 15 min after turning ON the power supply
.
Power OFF
The
E3MC may output a single pulse when the control power
supply
is turned OFF. If the E3MC is connected to a timer or counter to
which power is supplied from an independent power supply, the
E3MC
will be more likely to output a single pulse when the control
power
supply is turned OFF
. Therefore, supply
power to the timer or
counter
from the same power supply for the E3MC.
T
ypes of Power Supplies
No full-wave or half-wave rectified power supplies can be con-
nected
to the E3MC.
Power Supplies
Be
sure to ground the FG (frame ground) and G (ground) terminals if
a switching regulator is connected to the E3MC, otherwise the
E3MC
may malfunction due to the switching noise of the
switching
regulator.
Wiring
Cord
The
cord can be extended up to 100 m provided that the thickness of
the
cord is 0.3 mm
2
maximum.
Repeated Bending
The cord must not be bent repeatedly
.
High-tension Lines
The power supply lines of the Photoelectric Sensor must not be
wired
alongside power lines
or high-tension lines in the same con
-
duit,
otherwise the Photoelectric Sensor may become damaged
or
malfunction due to induction noise that may be generated from the
power
lines or high-tension lines. Route the lines separately or in a
single
conduit.
Cord Pulling Force
Do not pull cords with pulling forces exceeding 50 N.
Others
EEPROM Error
An
EEPROM error may result if power supply
to the Sensor fails or
the
Sensor is influenced by static noise. The operation and bank
in
-
dicators will flash and the buzzer will beep if there is an EEPROM
error,
in which case
perform teaching and make threshold level set
-
tings
again.
M12 Metal Connector
Make
sure to connect or disconnect the metal connector after turn
-
ing
of
f the E3MC.
Make
sure to hold the connector cover when connecting or discon
-
necting
the metal connector
.
Tighten
the metal connector securely by hand.
Do not use any tool,
such
as pliers, otherwise the metal connector may be damaged.
If
the metal connector is not tightened securely
,
the metal connector
may be disconnected by vibration or the proper
degree of protection
of
the E3MC may not be maintained.
W
ater Precaution
A
void using the Sensor in water
, rain, or outdoors.
Protective Cover
Tighten
the operation cover to a torque of 0.2 to 0.3
N
S
m to ensure
proper
waterproofing.
