SENSOR AND AMPLIFIER CONNECTIONS
Be sure to connect the sensing heads to the dedicated
E3C-T1A Amplifier.
To avoid damage to the Sensor, DO NOT connect the
E3C-T1L Emitter or E3C-T1D Receiver to the E3C-JC4,
E3C-JC4P, or the E3C-JB4P.
Be sure that the length of the bare core of each cable is 2 cm
maximum.
Securely tighten all terminal screws after wiring.

OPTICAL AXIS ADJUSTMENT
The E3C-T1 is used for the detection of minute objects. Because
the beam spot is very small, it may take some time to adjust the
optical axis.
For mounting, move the emitter and receiver up, down, left, and
right to position them in the center of the area that will turn the
light indicator on. Then, mount the emitter and receiver securely.

ENVIRONMENT
To avoid damage to the E3C-T1:
Do not use the E3C-T1 in places with explosive or flammable
gas.
Do not impose any voltage exceeding the rated voltage on the
E3C-T1.
Do not short-circuit the load connected to the E3C-T1.
DO NOT connect the E3C-T1L Emitter or E3C-T1D Receiver to
the E3C-JC4, E3C-JC4P, or the E3C-JB4P.
