The circuit of connection of the magnetic actuator through the push-button station into two buttons "Start" and "Stop". Instructions

To operate the asynchronous motor, push-button stations are used. However, they can only be connected via magnetic starters. As a rule, adapters and contactors are used for this. However, it is important to consider the type of circuit breaker and the parameters of the starter. In order to understand the connection of the device in detail, it is necessary to consider the standard scheme.

Wiring plan

The connection scheme of the magnetic starter via the push-button terminal assumes the use of an analog adapter. There are blocks for three and four outputs. For connection, the direction of the cathode is determined. The starter contacts are connected via a switch. The trigger for this is a two-channel type. If we consider devices with automatic switches, then they use an electrode regulator. The blocks can be located on the controller. The most common devices are devices with broadband connectors.

Consideration of switches QF1

The connection scheme of the magnetic starter via the push-button station has two controllers that are connected via an expander. The output contacts must be mounted on the plate. The device trigger is suitable for analog type. A normally closed contact of the first order is established in the zero phase. Resistance at the magnetic starter should be at least 40 ohms. A switch is checked before connecting the device.

The current relay in the circuit is used only as a two-channel type. The controller must be closed in the first phase. The switch is set to the upper position. When connecting the expander, the contacts are peeled off and the protective plate is loosened. The rectifier for stabilizing the process is selected by an open type.

Diagram with non-reversing starter

The connection scheme of the magnetic starter via the push-button terminal assumes the use of a low-resistance expander. Rectifiers in this case are connected to the winding of the converter. The normally closed contact of the circuit breaker is installed in the first phase. It should also be noted that filters can be used with a grid triode.

The resistance of the starter is on average 55 ohms. If we consider a circuit with a dipole adapter, the regulator is mounted on a pulsed rectifier. The output contacts are connected directly to the dinistor. A tester is used to check the post. It should also be noted that variable transducers are encountered. Starters with data elements can be connected via the controller to the zero phase. However, a filter with a magnetic triode is required.

Application of reversing starters

The connection scheme of the magnetic starter via the push button is very simple. It involves the use of only one rectifier. A filter can be used with a variable triode. Many models have two converters. In this case, the trigger is set to three outputs. A normally open contact is connected to the post through the first phase. To test the element, you need a tester.

The resistance level of the magnetic starter is at the level of 50 Ohm. If we consider modifications with adjustable transducers, then the dynistor can be selected on a binary filter. Some experts say that the outputs on the comparator must be carefully cleaned. It should also be noted that the tetrode in the starters should be correctly set.

Instruction for starters of the PML-1100 series

The starter circuit PML-1100 has three adapters. The output contacts must be closed in the zero phase. Checking the post is done using a tester. Experts say that it is not necessary to use analog converters, which have a low level of resistance. If we consider simple switches, then the trigger is set to receive a channel. The current relay is connected to the converter and closes in the first phase. If there are problems with overheating, you can try to reduce the load due to the comparator.

Connection of the modular starter

The starter circuit of the modular type contains contact adapters. Many models are made on three connectors. They have a positive contactor, which is connected via a converter. The trigger in this case is applied with the operating filter. If we consider simple switches, then the modules are connected through the controller in the first phase. The closing contacts must be at the top.

It should also be noted that there are modifications to four outputs. Triggers at them are established with regulators. When connecting devices it is important to carefully clean the contacts and check the device with a tester. In many models, the resistance index reaches a maximum of 40 ohms. Buttons of push-button stations close on the plate. Rectifiers are used in a positive direction. Dinistors are often installed on three adapters. The normal post is connected to the zero phase. If we talk about adjustable starters, then the trigger is of an analog type. In this case, only one switch is required. To do everything right, you have to measure the ultimate resistance in the circuit.

Starters of open execution

The open (manual) starter can be connected via a normal trigger. Controllers are most often used on four connectors. The output contacts are connected to the station in the zero phase, and the resistance should be about 45 ohms. Wired type controllers are connected to the converter. To check the phase, a tester is used. Starters with a di-stator are installed through an electrode adapter. Quite often, rectifiers use low conductivity. The closing contacts must be connected to the top of the panel. To avoid problems with malfunctions, it is important to check the insulation and take care of the rectifier.

Connection of closed-loop actuators

Starters of this type can be connected via a wired controller. In this case, the rectifier is usually applied with a lining. Experts recommend using only filters with a triode. If we consider the posts for two switches, then the trigger is chosen as a pulse type. In this case, the controller is firstly connected. Positive contacts are connected in the zero phase. The resistance on the controller must be at least 45 ohms.

If we consider modifications on capacitive flip-flops, then they need a converter. Use devices only in the DC circuit. Filters in this case are installed with a triode. Many starters use only one comparator. An element is used to protect the element. Also it should be noted that experts recommend carefully cleaning the contactors of the trigger.

Connection via unijunction trigger

The connection via the unijunction trigger can only be carried out in the first phase. It should also be noted that not all starters are suitable for this. Converters can only be used in a wired type. The resistance at them is obliged to make not less than 55 Ohm. Dinistors for starters are selected with an electrode triode. Directly the contacts of the post are closed on the expander.

Check the conductivity of the element with a tester. Experts do not recommend installing filters at increased resistance. The standard scheme involves the use of two rectifiers. If we talk about adjustable starters for asynchronous motors, then they have a comparator that is connected via a converter.

Using a two-trigger trigger

Two-transient triggers can be used in a DC circuit. They have a high resistance parameter. And they are suitable for starters of different types. Converters in the standard scheme are duplex type. Quite often there are digital analogues, which are released on two outputs. Many switches in devices are used with a rectifier. To connect the equipment, the first phase is determined. The resistance can be at least 45 ohms. With increased conductivity, the trigger with the cover changes.

Connection via dipole adapter

Dipole adapters can only be connected via the push-button to two buttons: "Start" and "Stop". Triggers are used, as a rule, of low-resistance type. If we consider a simple post, then the top contacts are closed first. It should also be noted that the controller can be connected via a converter, and its resistance is 55 ohms. The dinistor is often used with analog filters, which significantly increase the conductivity factor. It should also be remembered that linear triggers are not suitable for starters of this type. The adapter can be connected with the expander. Thus, the overload is greatly removed from the starter. The filter in this case is installed behind the comparator.

Using a wired switch

A wired switch can be connected through the transceiver, but only through the first phase. Many controllers are applied to two outputs. The expander is used in this case with one filter. The starter closes in the first phase. It should also be noted that the post should be installed behind the output contacts. If there are problems with the breakdowns in the circuit, the expander is checked.

Connection via the module

Only the electrode starters can be connected via the module. Posts in this case are selected two-button type. In some cases, the modules are produced in three outputs. And they have one controller. In this situation, a triode is used for connection. Closing contacts are exposed to the rhinestone in the first phase. It should also be noted that the expander is selected by the dipole type. If we talk about the model with the plates, then the closing contacts must be checked for ultimate resistance. At the same time, the expander's outlets are carefully cleaned. Also, it should be noted that open contacts are set to zero phase.
