These two attached Schematics were contributed by ECN Member "Pinemarten".
I have created a Discussion thread for these two items in the Electrical Theory and Applications area, which may be used to discuss these items with "Pinemarten" and others.
Look for the thread Discussion for: Member Contributed Motor Schematics-part 1
in the Electrical Theory section.
Here are the first two Schematics:
Fig. 1.1: Control Schematic
Fig. 1.2: Single Line Diagram
Some information regarding these items (text from Pinemarten):
150-200hp Westinghouse motor and control panel, circa 1968. It is still operating a skilift in western Canada.
The "Tranquilizer" at skimarmot.com.
24VDC combined with 120VAC control.
During power failures (rare, none in the 2002-03 season), a diesel auxilary drive engine (APU), can be started to run the lift on the 24VDC circuit with no loss of protection, or communication between the top and bottom stations.
