Two common methods used to reverse a three-phase motor are reversing magnetic motor starter and _________________ switches.

A drum switch provides a(n) __________________ method to change the direction of rotation for a motor.

A drum switch contains moveable contacts on an insulated ____________________.

Drum switches do not have _________________ protection to protect the motor.

A reversing magnetic motor starter has ________________ relay Coils.

Each relay in a reversing magnetic motor starter has its own set of _____________________________.

When connecting to the reverse side of a magnetic motor starter, L1 is connected to ______________________

When connecting to the forward side of a magnetic motor starter, L2 is connected to _________________.

When connecting to the reverse side of a magnetic motor starter, L3 is connected to _____________

To avoid ____________________ both coils of a reversing magnetic motor starter at the same time, interlocks are used.

The __________________ method of interlocking is the most common method. It uses the normally closed auxiliary contacts of the reversing magnetic motor starter.

The __________________ method of interlocking uses two double-pole Single-throw (DPST) pushbuttons to create the interlock.

The _____________________ method of interlock uses a lever to physically prevent the armature of one of the coils from moving.

Electrical interlocking is often used with mechanical interlocking to protect the coils from damage

In the manual mode of machine operation, operators often _____________ an actuator to position it.

The manual mode is most often used during machine set-up and _____________________.

A(n) ___________________ circuit uses a locking pushbutton to switch between manual and automatic modes.

A(n) __________________ switch is often used to select modes of operation.

The _________________ mode repeatedly cycles a machine.

The motor automatically runs continuously in the ______________________ mode.

A(n) ___________________ circuit provides a continually operating motor mode, Off mode, and automatic mode,

A(n) ___________________ circuit provides a jog mode, off mode, and automatic mode.

A common application for the H-O-A circuit is a(n) __________________ system for crops.

When the automatic mode is selected in a H-O-A circuit, the motor will not run until certain conditions are met.
