This 70-page book, which includes a large fold-out diagram for an actual rotary screw compressor control circuit, explains the fundamental lines and symbols used in ladder diagrams and also covers the principles of operation and symbols for switches, timers, potential devices used in refrigeration systems, alarm circuits, defrost cycles, and troubleshooting.
RETA study course workbooks, supplemented by instructor's presentation tools, provide widely used training aids designed specifically for the ammonia refrigeration industry. Thousands of these courses have been supplied to RETA local chapters for in-plant training programs, individual home study and use as textbooks in universities, junior colleges and trade schools.
A final exam is taken at the end of each RETA course. The lessons conclude with feedback questions to test understanding of the information presented.
