External Synchronous Input Function
The measurement results will be directly output to the control output if the input from the external synchronous input terminal (pink) is set
to OFF. The output will hold the previous status if the input of the external synchronous input terminal is set to ON. External synchronous
input is valid in RUN or ADJ mode. As for the 4-output models, this function applies to the output of all the channels.

Remote Teaching (Remote Control Function)
Mode Setting
When using the remote control function of the Sensor for remote
teaching, be sure to set the Sensor to mode B.
Setting Method
Apply power to the Sensor while pressing the SELECT DOWN
button and TEACH button together.
Checking Method
Mode A or B of the E3MC will be displayed for 3 s after mode set-
ting. When the mode selector is set to TEACH, the mode can be
checked from the operation indicator. The indicator will be lit when
the mode is set to B.
Note:
1.
The Sensor is set to mode A before shipping.
2.
The current mode selected does not change after the
Sensor is turned OFF.
3.
The remote control function is available in RUN mode
and ADJ mode only.
4.
The E3MC-M
@
has three outputs in mode B and no ex-
ternal synchronous input will be accepted.
5.
The same switching procedure can be used for chang-
ing to mode A.
Remote Teaching Method
Function 1: Remote teaching with manual input through a
mechanical switch
Short-circuit the remote control input for 1.5 s or more to either of
the following terminals according to the E3MC model.
Function 2: Remote control of teaching and bank selection
through the PLC or PT
Input one of the following signals as a remote control input. There
will be an answer-back output for 0.3 s if the signal is correctly
received.

This status can be on hold by an
external synchronous input. It
will be released by setting the
external synchronous input to
OFF.
This status can be on hold so
that unwanted color objects can
be ignored while they are pass-
ing the sensing range.
Mode A:
