2. Set the mode selector to TUNING.
3. Locate the object at the sensing position and press the tuning
button.

If tuning is OK: The tuning indicator turns green.

The built-in buzzer beeps once.
If tuning is NG: The tuning indicator (red) is still lit.
The built-in buzzer beeps 3 times.
Change the position of the object and the sensing distance that have
been set and repeat from the beginning.

5. Set the mode setting selector to RUN to complete the

sensitivity setting on the E3X.
The tuning indicator (green) is OFF.
6. Select the logical output required with the operation mode
selector.
Maximum Sensitivity Setting
1. Set the mode setting selector to TUNING.
2. Press the tuning button, at which time the object may or may
not be located at the sensing position.
The tuning indicator (red) is lit.
The built-in buzzer beeps once.
3. Set the mode setting selector to RUN to complete the
maximum sensitivity setting on the E3X. It will take
approximately three seconds for the stable operation
indicator or light reception indicator to be lit. After the
maximum sensitivity setting is completed, the tuning indicator
will turn green and then it will be automatically turned OFF in
approximately three seconds. The maximum sensitivity of the
E3X can be automatically set regardless of the set distance or
light reception.
Note: The sensitivity of the E3X-T11 and E3X-T21 are set to max-
imum before shipping.

Note: 1. If the indicators operate as described in the table, the E3X can operate in stable condition within the rated temperature range.
2. Even when the green indicator is OFF, the E3X will operate stably if the operating temperature change since the initial settings is
within +10°C.

Light Axis Adjustment with Flashing Function
E3X-Tjj
This function enables the user to adjust with ease the light axis of the through-beam fiber with the light source flashing. All E3X models have this
function.

1. Set the mode setting selector to FLASH. 2. If the axis of the light emission fiber head and that of the
light reception fiber head do not agree with each other
and the amount of light reception becomes 90% of the
peak value or less, the flashing function of the E3X will
Mode Setting Selector work. The E3X retains the peak value when the mode
setting selector is set to FLASH and the axes of the
fiber heads are adjusted to agree with each other.

Remote Tuning/Remote Bank Function (E3X-T21)

Remote Tuning Function
Basically, the method of remote tuning is same as that of sensitivity adjustment. When the remote tuning function of the E3X is used, the E3X is
tuned with the remote tuning input signal instead of the tuning button which has to be pressed.
1. Set the mode selector to RUN.
2. The following signal conditions must be given as remote
tuning input conditions.
Brown +V

Orange; self-diagnostis

Blue 0 V

If no remote tuning is done, cut off the purple wire at its

source or connect the pink wire to the positive terminal
of the power supply.

To set two kinds of sensitivity adjustment values, the
