9.3.6 Maintenance
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.
