Attention for Installation(Read this section thoroughly before installation.)

RPT4◆ Ensure the power is switched off during installation or
maintenance operations.
◆ Use a regulated power supply, e.g. switch-model type.
Simpler power supplies, such as a full-wave rectification type,will cause the permissible ripple rating to be exceed and may
cause malfunction.
◆ Ensure correct connections by reference to the wiring diagram.
◆ To avoid malfunction caused by induction noise, cable should
be kept apart from motor or other power cable.
◆ Please note that the signal may become unstable (false signal orchattering) when the transmission distance and the center offset areoutside the specification range.
◆ The inzone signal is a preliminary signal for confirming that the output
signal is established within the specification range. Please note that it
does not guarantee signals output outside the specification range.

Signaltransmission

DetectedsignalDetector: Connects DC2W or mechanical limit switches (max.4)
and transmits the detected signals to Transmitter.

Transmitter: Provides power for Detector, also passes detectedsignals from Detector to Output Sensor.

Please note that the cable length of an output sensor may not longer than
10m. The CE marking verifies that our products comply with the requirementsof EMC directive. The surge test to an output sensor is not carried out.
When using an output sensor with cable length longer than 10m, a measure
to protect the sensor from serge current should be taken.
