Application Precautions - Omron Z4LB V2 Instruction Manual

Application Precautions

2 Application Precautions
1. Users must operate the product according to the procedures and specifications
described in this manual. (Refer to 7-1 Specifications.)
2. Do not connect or disconnect a connector between the Sensor and Controller when the
power is turned ON, otherwise the Sensor may be damaged.
3. Warm up the Z4LB V2 for approximately 5 minutes after turning ON the power.
Power Supply and Wiring
1. Do not impose voltage exceeding the rated voltage, otherwise the Sensor may be
damaged.
2. When supplying power to the sensor, make sure that the polarity of the power is correct,
otherwise, the sensor may be damaged.
3. Do not short-circuit the load supplied with open collector output, otherwise the Sensor
may be damaged.
4. The Z49-C13 Extension Cable (3 or 8 m in length) can be connected to the sensor
cables or amplifier cables. The total length of the sensor cables or amplifier cables,
however, must be 10 m or less. Use a shielded cable to extend the amplifier cable, in
which case, a shielded cable that is the same as that of the amplifier cable must be used.
5. Do not lay a power supply cable for the Z4LB V2 together with high-voltage lines or
power lines to prevent interference, damage, and malfunction.
6. Use an isolation transformer for the power supply of the Z4LB V2 as shown in the
following.
