Hello.
I have to draw a control circuit schematic and wiring diagram for a 2 stop dumb-weighter (food elevator). This is used when a restaurant has a kitchen below the actual floor where the guests are served. The elevator is used to transport food and dirty dishes up / down(not people). However this particular elevator has certain requirements.
Criteria:
-Elevator doors open and close manually.
-Pilot/Indicating lights, on both floors, indicate the direction of travel - up or down
-Door interlocks disable the elevator during unloading and loading (when doors are opened the elevator is disabled)
-Elevator stops automatically at floor
-Low voltage protection is required
-Provide up and down buttons on each floor
-Provide emergency stop on each floor.
Any help is greatly appreciated.
