Maintenance
This section describes the routine cleaning and inspection recommended as
regular maintenance. Handling methods when replacing Controllers are also
explained here.
7-2-1
Cleaning
Clean the Controllers regularly as described below in order to keep the Net-
work in its optimal operating condition.
• Wipe the Controller with a dry, soft cloth for regular cleaning.
• When dust or dirt cannot be removed with a dry cloth, dampen the cloth
with a neutral cleanser (2%), wring out the cloth, and wipe the Controller.
• Smudges may remain on the Controller from gum, vinyl, or tape that was
left on for a long time. Remove these smudges when cleaning.
Note
Never use volatile solvents, such as paint thinner or benzene, or chemical
wipes to clean the Controller. These substances may damage the surface of
the Controller.
7-2-2
Inspection
Inspect the system periodically to keep it in its optimal operating condition.
In general, inspect the system once every 6 to 12 months, but inspect more
frequently if the system is used in high-temperature, humid, or dusty condi-
tions.
Inspection Equipment
Prepare the following equipment before inspecting the system.
Equipment Required for
Regular Inspection
A flat-blade and a Phillips screwdriver, a screwdriver for connecting communi-
cations connectors, a tester (or a digital voltmeter), industrial alcohol, and a
clean cloth are required for routine inspection.
Other Equipment that May
Be Required
A synchroscope, oscilloscope, thermometer, or hygrometer may be required.
Inspection Procedure
Check the items in the following table and correct any condition that is below
standard by adjusting the Controller or improving the environmental condi-
tions.
