Axis Adjustment
When the Sensor power is switched ON, the red transmitter indi-
cator is lit. Move the Sensor so that the red beam (see the figure
below) focuses on the object. The entire light beam should be
focused on the object or an error will result.

Connecting a Z4W-DD1C Linear Sensor
Controller
To discriminate among objects according to size, use the Z4W-
V25R LED Displacement Sensor with a Z4W-DD1C Linear Sen-
sor Controller.

The following equipment is required:
• Z4W-V25R LED Displacement Sensor
• Z4W-DD1C Linear Sensor Controller
• Synchronization Sensor (E3X Fiber Photoelectric Sensor or
E3C-VM Miniature Head Photoelectric Sensor is recommended)
• An object of standard dimensions
• An object of threshold dimensions
• Tools
Mounting
Mount as described on page 6.
When installing a Synchronization Sensor, refer to the instruction
manual and read the precautions for the model. It is important to
install the Synchronization Sensor so that the LED Displacement
Sensor can detect the object at the measurement position. Do not
tighten the mounting screws for the moment since the optical axis
must be adjusted.
The Z4W-DD1C Linear Sensor Controller can be mounted on a
wall and secured with screws, or mounted to DIN rail.
Wiring
Make sure that the Linear Sensor Controller, the LED Displace-
ment Sensor, and the Synchronization Sensor are wired correctly
before turning on the Linear Sensor Controller power (power is
supplied to the LED Displacement Sensor and the Linear Sensor
Controller by the Linear Sensor Controller). To avoid trouble,
leave the output terminals (No. 4, 5, 6) of the Linear Sensor Con-
troller open for the moment.

Axis Adjustment
After adjusting the optical axis of the LED Displacement Sensor,
adjust the optical axis of the Synchronization Sensor so that the
LED Displacement Sensor detects the object at the measurement
position in synchronous operation. Since the Linear Sensor Con-
troller operates synchronously on receiving each output signal of
the Synchronization Sensor, set the position of the Synchroniza-
tion Sensor so that the front edge of the object is detected by the
Synchronization Sensor.

After the optical axis has been adjusted, tighten the mounting
screws and secure the Synchronization Sensor firmly. Some Syn-
chronization Sensor models incorporate a sensitivity controller.
For the adjustment of such models, refer to the instruction manual
for the Synchronization Sensor.
