Handling Precautions - Panasonic GP-X Series User Manual

Handling Precautions

This product is to inspect (discrimirate/measure) sensing objects.
Never use this product for prevention of accidents which damage a
human life or properties or for safety maintenance.
WARNING
Connection
・The GP-X series is configured to satisfy the specification with the
combination of the sensor head and the controller. Use the sensor head
and controller in combination without fail; with other combinations, not only
may the specifications may not be satisfied but also failure may result.
・Turn the controller off before mounting or removing the sensor head and
controller.
・Note that the cables will be damaged if they are pulled.
Power Supply
・Wait 15 minutes (or 20 minutes with GP-X3S and GP-X5S) after the power
is turned on before operation is started. There may be a variation in the
measurements immediately after power-on because the power circuit is not
stable.
・There is a muting time of about two seconds after the power is turned on.
Take care that wrong wiring may damage the sensor.
・Verify that the supply voltage variation is within the rating.
・If power is supplied from a commercial switching regulator, ensure that the
frame ground (F.G.) terminal of the power supply is connected to an actual
ground.
・Make sure to use an isolation transformer for the DC power supply. If an
auto-transformer (single winding transformer) is used, this product or the
power supply may get damaged.
・In case a surge is generated in the used power supply, connect a surge
absorber to the supply and absorb the surge.
Wiring
・Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
・Make sure that the power supply is off while wiring.
・The analog voltage output is incorporated with a short circuit protection
circuit. Do not connect it directly to a power supply or a capacitive load.
・Be careful to avoid statically charging connectors during wiring work. A
failure may result.
・Use the exclusive extension cable for cable extension of the sensor head.
