Warm-up Time
In order to ensure the performance of the system, allow a warm-up time of at least
30 minutes after the system is turned ON.
Countermeasures against Noise
•
Install the system separated as much as possible from noise generating sources,
such as high-tension lines, high-voltage equipment, power lines, power
equipment, machines generating high-voltage ON/OFF surges, welding machines,
and inverter motors.
•
Install the system separated as much as possible from radio equipment incorporating
transmission circuitry, such as amateur radio transmitters.
・
Do not touch the connector parts when the system is energized. Keep in mind that
the internal circuit may be damaged if an excessive level of static electricity is
imposed on the connector parts.
•
Separate the sensor cable from other wires at least 100 mm, and make sure that
the sensor cable is not in parallel with them. Separate the sensor cable from
high-voltage and power circuit lines. Shield the sensor cable with grounded
conduits if it is unavoidable to lay the sensor cable together with high-voltage or
power circuit lines.
•
Separate the I/O signal lines at least 100 mm away from power lines and power
supply lines. All signal lines should be connected as short as possible.
•
The analog output of the system is adversely influenced by heavy noise in the
power supply. In that case, use a noise filter or noise-cut transformer.
•
It is recommended to use shield cables for I/O signal wires and connect the
shields to the frame ground (FG) for countermeasures against noise.
•
The analog output is easily affected by external noise. Use the shield cable and
lay it as short as possible.
