Troubleshooting
The following are the major causes of ID Controller malfunctioning:
Influence of Noise
If the system malfunctions due to noise, take appropriate countermeasures
against noise by referring to the following table:
Cause
Measures
Influence of noise
Take countermeasures against noise.
Malfunctioning of external devices
Repair is needed.
Malfunctioning of ID Controller
Others
No.
Occurrence
Possible cause
Countermeasures
1
On power application to
motor, transformer, or capaci-
tor.
Momentary voltage drop due to
inrush current of large load.
Increase the capacity of the power supply
facility or use larger power cables.
Common mode noise due to the
above.
Supply power through 1:1 non-grounded
insulated transformer.
Do not share the ground lines with other
high-capacity loads. Independently ground
at less than 100
Ω
.
2
Irregular.
Noise superimposed on power
lines.
Supply power through 1:1 non-grounded
insulated transformer or noise filter.
3
Input signal turns ON when it
should be OFF.
Inductive noise of input wiring.
Separate input signal lines from other
power lines.
If the influence of noise is high, route input
lines using a grounded metal conduit or use
shielded cables.
