Dec 09, 2015 · HAND-OFF-AUTOMATIC CONTROLS. Recognize hand-off-automatic switches on a schematic diagram. Hand-off-automatic controls are used to permit an operator to select between automatic or manual operation of a motor. The circuit shown in Figure 27–1 permits a motor to be operated by a float switch or to be run manually.

Wiring diagrams. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called "main" or "construction" diagrams, show the actual connection points for the wires to the components and terminals of the controller. Basic wiring for motor control – Technical data

The wiring diagram for a three-phase gearmo-tor is located inside the terminal box which is attached to the gearmotor. The wiring diagram for a variable speed ... On variable speed conveyors, set the control at its lowest speed. Run the conveyor and observe the belt tracking at both ends. Gradually increase the speed (cycle time).

PLC Conveyor Interlock This is PLC Program for controlling sequence of conveyors and interlocking them. Problem Description. A feeder drops material on the conveyor which sends material for further process through one more conveyor. Conveyor must start automatically when material is dropped.

:INFO: See Application Drawing - A9200 for pneumatic diagrams. Manifold air lines supply regulated air from the regulator assembly (located on the discharge end of the drive assembly), to the tubing and other pneumatically operated optional components on each conveyor unit.

Wiring diagrams help technicians to see how the controls are wired to the system. Many people can read and understand schematics known as label or line diagrams. This type of diagram is like taking a photograph of the parts and wires all connected up. These diagrams show the actual location of parts, color of wires, and how they are connected.

conveyor monitor. The control unit accepts signals of belt speed, belt alignment and bearing temperature from sensors mounted on the bucket elevator or belt conveyor and is able to sound an alarm and provide shutdown control of the elevator or conveyor, and feeding system, when a potentially hazardous condition is detected.

The interlock contacts installed in the previous section's motor control circuit work fine, but the motor will run only as long as each push button switch is held down. If we wanted to keep the motor running even after the operator takes his or her hand off the control switch(es), we could change the circuit in a couple of different ways: we could replace the push button switches with toggle ...

The speed of the conveyor motor will increase or decrease as the DC voltage from the board increases or decreases respectively. NOTE: The conveyor control uses a sensor and magnet mounted on the conveyor motor that senses the motor speed. Any change in motor load (± RPM) is detected by the sensor and the voltage to the

A coordinated start/stop control system for controlling the operation of ple conveyor checkout systems, wherein the operation of a pair of rear transport belts is selectively controlled in response to the operation of a first transport belt, dependent on the actuation of a magnetically operated electrical switch by a control magnet mounted on a diverter bar or arm.
