Before Use - Omron ZG2 Series User Manual

Observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
1. Installation Site
Do not install this 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
• When using a commercially available switching regulator, make sure that the FG
terminal 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 devices, make sure that the Sensor/Controller is
turned OFF. The Sensor or Controller may break down if it is connected/disconnected
while the power is ON.
• Use the extension cable sold separately for extending the cable between the Sensor
and the Controller.
p.17
• Use only combinations of the Sensor and Controller specified in this manual.
• Before turning the Controller ON, connect the Sensor. If the Controller is turned ON
without the Sensor connected, the Controller's screen will remain dark and messages
cannot be read.
3. Warming Up
After turning the power supply ON, allow the product to stand for at least 30 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measurement values may fluctuate gradually.
