Autonics TM4 Series - Noise Effect; Communication

Handling Precautions
© Copyright Reserved Autonics Co., Ltd. ix
 When changing an input sensor, first disconnect power to the product and then
connect the new sensor. Restore power to the product and update the related
parameters either directly from the product or using the PC loader program.
 Always use a line filter on the controller's power line. Also, use shielded wire for the
input signal line, provided it is necessary for the power line and the input signal line
must remain close to one another.
Noise Effect
 Isolate the product's wiring from high-voltage lines and power lines to prevent impulse
noise.
 Avoid using the product in the vicinity of high-frequency noise generating devices,
such as: welding machines, sewing machines, high-capacity SCR controllers, and
high-capacity motors.
 Avoid using the product in the vicinity of radio, television, and wireless devices that
may cause high-frequency interference.
Communication
 Only use twisted pair wires for the communication lines. Attach round ferrules at the
ends of the lines to reduce the impact of external noise.
 Do not have the communication lines in close proximity of the AC power line.
 If possible, use a separate power source (24 VDC) for the communication converter
(SCM-38I, sold separately).
