E2C-EDA
End Plate Mounting (PFP-M)
Mount End Plates on Amplifier Units to avoid movement due to
vibration. When a Mobile Console is installed, mount the End Plate
facing as shown in the following diagram.
End Plate
Mounting a Communications Head for the Mobile Console
Leave a space of at least 20 mm on the left side of the Units for a
Mobile Console Communications Head.
20 mm
EEPROM Write Error
If the data is not written to the EEPROM correctly due to a power
failure or static-electric noise, initialize the settings using the keys on
the Amplifier Unit.
Optical Communications
When using more than one Amplifier Unit, mount the Units side-by-
side. Do not slide or remove Units while they are in use.
Miscellaneous
Protective Cover
Be sure to put on the Protective Cover before use.
Mobile Console
Use the E3X-MC11-SV2 Mobile Console for E2C-EDA-series
Amplifier Units. Other Mobile Consoles, such as the E3X-MC11,
cannot be used.
Sensor Head and Amplifier Unit Connection
Be sure to use only specified Sensor Head and Amplifier Unit
combinations. The E3C-LDA-series Photoelectric Sensor with
Separate Digital Amplifier is not compatible, and the E2C-EDA must
not be used with products from that series.
Warm-up
The digital display will slowly change until the circuits stabilize after
the power is turned ON. It takes about 30 minutes after the power is
turned ON before the E2C-EDA is ready to sense.
Maintenance Inspection
• Be sure to turn OFF the power before adjusting, connecting, or
disconnecting the Sensor Head.
• Do not use thinner, benzene, acetone, or kerosene to clean the
Sensor Head or Amplifier Unit.

• Use the dimensions from the following table to mount unthreaded
cylindrical models (E2C-ED-@@). Do not tighten screws with
torque exceeding 0.2 N·m when mounting Sensor Heads.

• Do not use torque exceeding 0.5 N·m to tighten screws when
mounting flat models (E2C-EV@@).
• Use a bending radius of at least 8 mm for the Sensor Head cable.
• Use only the special extension cable to extend the cable between
the Sensor Head and the Amplifier Unit.

Effects of Surrounding Metal
• Provide a minimum distance between the Sensor and the
surrounding metal as shown in the table below.

Mutual Interference
• If more than one Sensor Head is installed face to face or in parallel,
make sure that the distances between two Units adjacent to each
other are the same as or larger than the corresponding values
shown in the following table.
• The distance between Sensor Heads may be narrower than specified with
these Sensors because the Mutual Interference Prevention Function is
used for optical communications between the Amplifier Units.
