E3X-NA

E3X-NA

Adjuster type standard that is the culmina­tion of true ease and simplicity

Features

Instinctive LED bar displays of light levels

The previous manual type used the stability and incident level
indicators to display the light level change, which was difficult
to understand at a glance. The E3X-NA uses the LED bars to
display the light level, ensuring the light level change at a
glance.

Operation indicator

Approx. 20% or lower
Approx. 10% or lower

Unstable level

Approx. -20% or higher

* The vertical movement

shows the light level

Design

Communications Hole

The window provided in the side face of the unit is a commu­nication window for prevention of mutual interference when it
is connected with the other unit. Note that the optional Mobile
Console E3X-MC11 cannot be used. When the incident level
of the sensor is excessive, mutual interference prevention
may not be activated. At that time, make adjustment with the
sensitivity adjuster. When the unit is used with the E3X-DA-N
series, mutual interference prevention is not activated.

Mounting

Connection/removing of amplifier units

(Connection)

1. Install the Amplifier Units one at a time onto the DIN track.

2. Slide the Amplifier Units together, line up the clips, and
press the Amplifier Units together until they click into place.

(Removing)
Slide one unit away from the other and remove them one by
one. (Do not remove the connected units together from the
DIN rail.)

Note: 1 .When the amplifier units are interconnected, the operating ambient

temperature changes depending on the number of connected am­plifier units. Check "Ratings/Performance".

2 .Before connecting or removing the units, always switch power off.

Ambient Conditions

Always remove dust, dirt, etc. from the optical communication
window, which may disable communication.

Installation

Installation Connectors

1. Insert the Master or Slave Connector into the Amplifier Unit
until it clicks into place.

Insert

2. Join Amplifier Units together as required after all the Master
and Slave Connectors have been inserted.

3. Apply the supplied seal to the non-connection surface of the
master/slave connector.

Mounting End Plate (PFP-M)

Depending on the installation type, an Amplifier Unit may
move during operation. In this case, use an End Plate.
Before installing an End Plate, remove the clip from the mas­ter Amplifier Unit using a nipper or similar tool.

The sensor bottom is also equipped with the clip removing
mechanism.

1. Insert the clip to be removed into the slit underneath the clip
on another Amplifier Unit.

Sticker

Note: Apply the seal to the grooved side.

Sticker

Removing Connectors

1. Slide the slave Amplifier Unit for which the Connector is to
be removed away from the rest of the group.

2. After the Amplifier Unit has been separated, press down on
the lever on the Connector and remove it. (Do not attempt
to remove Connectors without separating them from other
Amplifier Units first.)

Press down

2. Remove the clip by rotating the Amplifier Unit.
