Precautions for Correct Use

Please observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
(1) Installation Location
Do not install the product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85 %
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Reflection of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
(2) Power Supply and Wiring
• Supply power from a DC power supply unit that has a countermeasure (safety ultra-
low voltage circuit) built-in for preventing high voltages from occurring.
• When using a commercially available switching regulator, make sure that the FG ter-
minal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• Before turning ON the power after the product is connected, make sure that the power
supply voltage is correct, there are no incorrect connections (e.g. load short-circuit)
and the load current is appropriate. Incorrect wiring may result in breakdown of the
product.
• Before connecting/disconnecting the Sensor Head, make sure that the Smart Sensor
is turned OFF. The Smart Sensor may break down if the Sensor Head is connected or
disconnected while the power is ON.
• Use extension cord ZFV-XC_B(R)V2 sold separately for extending the cord between
the sensor head and amplifier unit. Two ZFV-XC_B(R)V2 cords can be coupled
together to extend the cord length. In addition, use a robot cable type extension cord
(ZFV-XC_BRV2) at locations where the cord bends, to prevent damage to the cord.
• Use only combinations of Sensor Heads and Sensor Controllers specified in this man-
ual.
• Do not turn OFF the power in the following cases.
- Immediately after the mode is switched from MENU or ADJ mode to RUN mode
- While teaching operation using the parallel signal is in progress
Do not turn off the power until the ENABLE signal is turned ON. Failure to do so may
initialize the bank data.
