Control unit preventive maintenance
Preventive maintenance consists of cleaning the instrument regularly and inspecting it occasionally for broken or
damaged parts. Regular maintenance will improve the reliability of your instrument and prevent breakdowns.
Cleaning - Accumulations of dirt and dust on components act as an insulating blanket preventing efficient heat
dissipation. Dust on circuit boards and wires can cause arcing and short circuits, resulting in damage to
components or even instrument failure. Clean your instrument with clean high-pressure air before this happens!
The control unit chassis provides protection from dust and dirt and should be in place during normal operation of
the instrument.
Exterior - Dust the chassis with a soft cloth. Dust the front panel with a soft paintbrush. Dirt clinging to the
surface can be removed with a soft cloth dampened with a mild detergent and water solution. Avoid using
abrasive cleaners, as they will scratch the housing and front panel.
Interior - Dust in the interior of the control unit should be removed before it builds up enough to cause arcing
and short circuits during periods of high humidity. Dust is best removed from the interior by the type of canned
air used for computer cleaning. Dirt clinging to the surfaces can be removed with a soft paintbrush.
Visual Inspection - Inspect the interior occasionally for broken connections, improperly seated semiconductors,
damaged or improperly installed circuit boards, heat damaged components, etc. If heat damaged components are
found, care must be taken to find the cause of the excessive heat and measures must be taken to prevent
recurrence of the damage.
Semiconductor Checks - Periodic checks of the semiconductor devices in this instrument are not recommended.
The best check of semiconductor performance is actual operation of the instrument.
Weather cover/blower preventive maintenance
Periodically - Check and inspect all hoses and wire connections inside the weather covers.
Air Filter - Remove and inspect replace the filter cartridge as necessary. EMS p/n 2122
