This section describes cleaning and inspection procedures that are to be per-
formed as daily maintenance.

Conduct the following periodic cleaning to keep the Controller Link Unit in
optimum condition.

• Wipe the Unit with a dry, soft cloth daily.

• For stains that cannot be removed with a dry cloth, dip the cloth in

medium strength alcohol (2%), wring the cloth tightly, and then wipe down
the Unit.

• If glue, vinyl, or tape is left on the Unit for long periods of time, it will stain.

Remove these items during cleaning.

!Caution

Do not use volatile solvents such as benzine or paint thinner, or chemical
cloths for cleaning. They will damage the quality of the coating on the Unit.

Controller Link Units must be inspected on a regular basis to ensure correct
operation. Inspections should be conducted once every 6 to 12 months. If the
Unit is subject to extremes in temperature or humidity, inspections should be
conducted on a more regular basis.

The following tools and equipment will be needed to perform inspection and
adjustments.

• Assorted flat-blade and Phillips screwdrivers

• Circuit tester or digital voltmeter

• Industrial-grade alcohol and clean cotton cloth

• Synchroscope

• Pen-chart recording oscilloscope

• Thermometer, hygrometer

Inspect the follow items to see if they deviate from the prescribed standards. If
any items do deviate from the standard either adjust so they are within the
operating range or adjust the Unit accordingly.
