This section describes how to inspect and clean the unit.
Inspection and Cleaning
■ Inspection
Connectors become loose when a KV Series unit is used for a long time. If you
continue to use a KV Series unit with loose connectors, this may cause the unit
to malfunction.
For this reason, you must periodically inspect the unit and connectors.
Generally, inspect the following points:
•
Are connection parts disconnected or loose?
• Are connectors disconnected or loose?
• Are the terminal screws on the terminal block loose?
• Are relays fused or their contacts faulty?
• Are connector cables between units and instruments damaged?
■ Cleaning
Dirt adheres to the CPU and other units when they are used continuously for a
long time. Clean off any dirt on these units with a clean cloth.
Before removing any dust or dirt from fine parts such as connectors, remove the
connector and then remove with a cotton swab.
