Concerning the illustrated motor controller...

🔍 Key Concepts

• How normally closed (NC) stop buttons and normally open (NO) start buttons are usually arranged in a standard motor control circuit with both local and remote stations • How to tell from the diagram whether components are in series or parallel in the control circuit to the KM1 coil • Where the pilot (status) light is connected in relation to the KM1 coil and contacts, and what that usually indicates about motor status

💭 Think About

• Trace the control circuit from the transformer secondary, through the overload contact, through all stop switches, start switches, and finally to the KM1 coil. Which devices must all pass current for the motor to run? • Look carefully at the symbols for the local and remote pushbuttons: which ones are NC and which are NO, and are any of the corresponding contacts drawn side‑by‑side (parallel branches) or in a single line (series)? • Check how the status light is wired: is it energized only when KM1 is picked up, or when KM1 is dropped out? What does that tell you about whether it is a “motor running” or “motor stopped” light?

✅ Before You Answer

• Verify which pushbuttons (local vs remote) are NC stop contacts and which are NO start contacts by their symbols. • Confirm from the lines in the schematic whether the two stop buttons share the same current path (series) or create alternate paths (parallel). • Identify whether the status light is wired in parallel with the KM1 coil or its auxiliary NO contact (typical for a running light) or across a NC contact (typical for a stopped light).

Concerning the illustrated motor controller circuit, which statement is true? See illustration EL-0004.

The local and remote start button switches are wired in series with one another.

The local and remote stop button switches are wired in parallel with one another.

The motor status light is a motor "stopped" light..

The local stop switch and the overload relay reset mechanism utilize the same button.
