6.3.4
6.3.5
• Use procedures, aids, and technical information in
this manual to locate and repair malfunctions
• Check the "obvious" (e. g., disconnected power cord) be-
fore investigating more difficult-to-locate causes of
malfunction.
• When a tlial-and-error replacement approach must be
used, start with the easiest-to-verify alternative.
• Do not remove or replace fuses with power cord connected.
•
•
•
Do not remove or replace circuit cards when terminal
power is on.
Consider temperature possibilities when investigating
an intermittent problem.
Transistor failure is often caused by failure of another
component. Investigate this possibility before replac-
ing a transistor.
Keep terminal clean, inside and out.
Solder qulckly and use heat shunts to prevent heat
. damage.
• Avoid excessive card extraction and insertion.
Replaceable Parts
Replaceable parts are listed in Section 9.
NOTE: Use OMRON or OMRON-approved parts only. The use of
other parts can void the manufacturer's warranty.
Workmanship
Bench maintenance recommendations and procedures presume high workman-
ship standards. Any damage caused by the use of improper tools, carelessness, mis-
treatment, or substandard workmanship voids the manufacturer's warranty, as will
using component leads for studs and making unauthorized modifications.
