Precautions

AVOID DAMAGE TO THE E3MC
• Voltage must not exceed the rated voltage of the E3MC.
• When supplying power to the E3MC, make sure that the
polarity of the power is correct.
• Do not short-circuit the load connected to the E3MC.

INSTALLATION
Power Up Ready
• The E3MC is ready to sense objects 100 ms after the unit is
turned ON.
• The 100 ms wait is also required when the E3MC output is
controlling other devices.
• If power is supplied to the E3MC and the load independently,
be sure to turn ON the E3MC first.
• When the E3MC is turned ON or OFF, the operation indicator
will be illuminated for an instant, but no control output will be
turned ON.
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, you should supply power to the timer or counter from
the same power supply as the E3MC.
Power Supplies
• Power supply must be filtered with 10% MAX ripple (see
supply voltage specification).
• When a switching regulator is required, you must connect the
FG (frame ground) and G (ground) terminals together, eliminat-
ing the switching noise of the regulator to avoid a malfunction.

WIRING
Cable
• The cable can be extended up to 100 m, allowing for a cable
thickness of 0.3 mm² maximum.
• The cable must not be repeatedly bent.
• Do not pull cables with pulling forces exceeding 50 N
(11.24 lb  force).
M12 Metal Connector
• When connecting or disconnecting the cable, first remove the
power to the E3MC.
• To avoid damage, tighten the metal connector securely by
hand. Do not use any tools.
• To ensure that the enclosure rating is maintained (so that
water/vibration ratings are assured), the cable connector
must be securely hand-tightened.
Avoid Damage or Malfunction Due to Induction Noise
• Never run the E3MC Color Sensor cables in the same con-
duit with power lines or high tension cables.

FURTHER INFORMATION
Correcting an EEPROM Error
• An EEPROM error may result if the power supplied to the
Sensor fails, or if the Sensor is influenced by static noise.
When an EEPROM error occurs, the operation and bank
indicators will flash and the buzzer will beep. The remedy is
to reprogram and make threshold level settings again.
