OPERATION SEQUENCE
The following simplified explanations give you a general knowledge of cycle
functions for each type of cycle phase. Refer to figures 1-7 through 1-10. A more
detailed description is found in paragraph 1-6, Cycle Phase Description.
a. Solid State Relay Lights. Each action during a phase is indicated by
a numbered SSR light located in the panel control box. When an SSR light is on, the
corresponding solenoid valve should be energized. All two-way solenoids used in this
equipment are normally closed.
