Section II. TROUBLESHOOTING

2-4. SCOPE. This section provides information for locating and correcting problems in the collective protec-

tion equipment. Use the following flow charts to isolate component problems and to locate repair instructions.

2-5. FLOW CHART PROCEDURES. This troubleshooting procedure is set up so that you actually are per-

forming a module functional checkout. For example, if you have a good compartment control module, you

perform only the functional checkout (yes path). If the compartment control module is defective (no path), the

procedure directs you step-by-step to locate a defective component or a wiring problem. After module repair,

you repeat the functional checkout at the point in the troubleshooting procedure where you originally dropped

out. The following describes the troubleshooting chart symbols.

WARNING

High voltage is used to power this equipment. Before removing or installing power cable, be

sure that POWER switch on control module is set to OFF and power source is shutdown to

avoid personal injury or loss of life.
