Questions
1. If the master switch is closed, what action will energize the relay coil?
2. If the master switch is open, what action will energize the relay coil?
3. If the master switch is closed and the "ON" pushbutton is
closed, what will happen?
4. If the master switch is closed and the "ON" pushbutton is open,
what will happen?
5. If the master switch is closed and the "ON" pushbutton is
closed, in this case the coil does not energize. What might be the cause?
6. If the potential voltage difference between L1 and L2 is 120 volts, what
is the proper coil voltage for this relay circuit?
7. With no wiring changes, what action will result in the coil going to a
run condition?
8. Can this relay circuit be described as a JOG type?
9. When 120 volt power is first applied to this relay circuit, what will
happen?
