SECTION 5:
MAINTENANCE AND TROUBLESHOOTING
SAFETY WARNING!
Read the Personal Hazard Warning now (page
). Disconnect primary power before opening enclosures.
Work safely, as follows:
1.
Remove rings and watches before opening the equipment.
2.
Shut off the equipment and wait one minute before proceeding.
3.
Remove the component or connect the test instruments.
4.
Replace the component.
5.
Turn on the power and test the system.
6.
Turn off the power and disconnect the test equipment.
PREVENTATIVE MAINTEN ANCE
Carry out the following inspection and cleaning procedures at least once per year:
1.
Verify that moisture has not accidentally entered the equipment through gaskets or seals, or collected
inside as condensation
2.
Verify that all drain holes are clear
3.
Check terminal blocks and relays for corrosion or arcing. Clean or replace any component that shows
evidence of high-voltage damage.
4.
Check all electrical connections for tightness and verify the absence of corrosion or electrical arcing.
5.
Clean the outside surface of the lens with liquid detergent and water. Wipe it gently with a soft clean cloth
or paper towel.
6.
Check the circuit boards to ensure that they are free of accumulated dust. Brush and vacuum as necessary.
Note: Do not use compressed air to clean this equipment.
STORAGE
When not in use, equipment should be stored indoors. Circuit boards (PCBs), when not installed should be kept in
antistatic bags or containers.
RFI PROBLEMS
The presence of radio frequency interference (RFI) can burn out components, cause a light to flash intermittently,
at the wrong rate, or at the wrong intensity. RFI can enter the light by any wire to or from the unit. The circuits are
designed to reject or bypass RFI, but Flash Technology cannot guarantee complete immunity. After installation,
you may find it necessary to add external filters or use other methods to reduce RFI entering the equipment.
DIAGNOSTIC TEST
The FTC 270 has built in diagnostic capabilities to assist in troubleshooting the system. Flash Technology
recommends that a full system diagnostic test is run before troubleshooting individual system components.
