RELAY BOARD
Layout, Legend & Diagnostic Test Points
The relay board provides a centralized location for wire harness connections and power transfer through board
relays (K1-K4) to the other steamer controls. Also, provides for condition or component troubleshooting by utilizing
seven voltage test points (T1-T7) on the board to verify the voltage status for the condition or component in the
operating sequence. When the condition for the component
<
s voltage measurement is satisfied or activated,
120VAC can be measured between T1 (ref.) and T2 thru T7 test points to indicate whether the condition or
component is receiving voltage to energize and operate. If the voltage is not present, then the condition or
component has not been energized or is not activated.
