Troubleshooting
There are four major causes of ID Controller problems:
■
Influence of Noise
If the system malfunctions due to noise, take appropriate countermeasures against noise by referring
to the following table.
No.
Occurrence
Possible cause
Countermeasures
1
Problem occurred when power was
turned ON to high-capacity motor,
transformer, capacitor, etc.
Momentary voltage drop due to inrush
current of large load
Increase the capacity of the power
supply or use larger power cables.
Common noise cause by the above
• Supply power through a 1:1 non-
grounded insulated transformer.
• Do not share the ground lines with
other high-capacity loads. Indepen-
dently ground to less than 100
.
(Figure 1)
2
Irregular problems
Noise superimposed on power lines
Supply power through a 1:1 non-
grounded insulated transformer or
noise filter. (Figure 2)
3
Input signal turns ON when it should
be OFF.
Inductive noise on input wiring
• Separate input signal lines from other
power lines.
• If the influence of noise is strong,
route input lines using a grounded
metal conduit or use shielded cables.
• Influence of noise••••••••••••••••••Take countermeasures against noise.
• Malfunctioning of external devices
• Malfunctioning of ID Controller
• Other
•••••••Repair is required.
