Section 5 – Maintenance and Troubleshooting

Safety

Warning!

Read the warning on Page ii now.

Disconnect primary power before opening

enclosures.

Work safely, as follows:

1. Remove rings and watches before

opening the equipment.

2. Shut off power to the equipment and

wait 5 minutes before proceeding.

3. Remove the component or connect the

test instruments.

4. Replace the component.

5. Apply power to the equipment and test

the system.

6. Shut off power to the equipment and

disconnect the test equipment.

Preventive Maintenance

Carry out the following inspection and

cleaning procedures at least once a 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 cloth or paper

towel.

Storage

When not in use, equipment should be

stored indoors. Circuit boards (PCB’s),

when not installed in the equipment,

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 SC 370 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.

Component Testing

Always make resistance measurements

with the primary power turned off.

However, you must make voltage

measurements with power applied. Thus,

for your safety, carry out all preliminary

steps such as connecting test leads or

circuit jumpers or disconnecting existing

circuit connections with the power off.
