For the operation of an induction motor, button posts 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 switch and the parameters of the starter. To understand in detail the connection of the device, you need to consider the standard scheme.
Wiring diagram
The connection diagram of the magnetic starter through the push-button post involves the use of an analog adapter. There are blocks for three and four exits. For connection, the direction of the cathode is determined. Starter contacts are connected via a switch. The trigger is suitable for this two-channel type. If we consider devices with automatic switches, then they use an electrode regulator. In this case, the blocks can be on the controller. The most common are devices with broadband connectors.
Review of QF1 circuit breakers
The connection diagram of the magnetic starter through a push-button post has two controllers that are connected through an expander. Output pins should be mounted on the plate. The trigger for devices is analog type. A normally closed contact of the first order is established in the zero phase. The resistance on the magnetic starter must be at least 40 ohms. Before connecting the device, the switch is checked.
The current relay in the circuit is used only two-channel type. The controller in this case must be closed in the first phase. The switch is set to the upper position. When the expander is connected, the contacts are stripped and the protective plate is unscrewed. The rectifier to stabilize the process is selected open type.
Non-reversible starter circuit
The connection diagram of the magnetic starter through the push-button post assumes the use of a low-resistance extender. Rectifiers in this case are connected to the transformer winding. The normally closed contact of the circuit breaker is set in the first phase. It should also be noted that filters are allowed to be used with a grid triode.
The starter resistance is on average 55 Ohms. If we consider a circuit with a dipole adapter, then the controller is installed on a pulse rectifier. The output contacts are closed directly on the dynistor. To check the post, a tester is used. It should also be noted that there are variable converters. Starters with these elements can be connected through the controller in zero phase. However, a magnetic triode filter is required.
The use of reversing starters
The connection diagram of the magnetic starter through the push-button post is very simple. It involves the use of only one rectifier. A filter can be used with a variable triode. Many models have two transducers. In this case, the trigger is set to three outputs. The normally open contact is connected to the post through the first phase. You will need a tester to check the item.
The resistance level of the magnetic starter is at 50 ohms. If we consider modifications with adjustable converters, then the dinistor 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 must be correctly set.
Instructions for starters PML-1100
The PML-1100 starter circuit has three adapters. The output contacts must be closed in zero phase. Checking the post occurs with the help of 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 for channel reception. The current relay is connected to the converter and closes in the first phase. If there are problems with overheating, then you can try to reduce the load due to the comparator.
Connecting a modular starter
The modular-type starter circuit 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 used with an operational 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 are installed with regulators. When connecting devices, it is important to carefully strip the contacts and check the device with a tester. In many models, the maximum resistance value reaches 40 Ohms. Buttons of button posts are closed on the plate. Rectifiers are used in a positive direction. Dinistors are often installed on three adapters. Normal post is connected in zero phase. If we talk about adjustable starters, then the trigger is used analog type. In this case, only one switch is required. To do everything right, you have to measure the ultimate resistance in the circuit.
Open Actuators
An open type (manual) starter is allowed to be connected via a conventional trigger. Controllers are most often used on four connectors. The output contacts are connected to the post in 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 dinistor are installed through an electrode adapter. Quite often, rectifiers use low conductivity. The make contacts must be connected at the top of the panel. To avoid malfunctioning problems, it is important to check the insulation and take care of the rectifier.
Connection of closed-circuit starters
Starters of this type can be connected via a wired controller. In this case, the rectifier is standardly used with a lining. Experts advise using only filters with a triode. If we consider the posts on two switches, then the trigger is selected pulse type. In this case, the controller is primarily connected. Positive contacts are connected in zero phase. The resistance on the controller must be at least 45 ohms.
If we consider modifications on capacitive triggers, then they need a converter. You can only use the device in a DC circuit. Filters in this case are installed with a triode. Many starters use only one comparator. To protect the element, a cover is used. It should also be noted that experts recommend thoroughly cleaning the trigger contactors.
Connection via a single jumper trigger
Connection through a single-junction trigger can only be done in the first phase. It should also be noted that not all starters are suitable for this. Converters can only be used wired type. Their resistance must be at least 55 ohms. Dinistors for starters are selected with an electrode triode. Directly, the contacts of the post are closed on the expander.
You can check the conductivity of the element using a tester. Experts do not recommend installing filters with high resistance. The standard scheme involves the use of two rectifiers. If we talk about adjustable starters for induction motors, then they have a comparator, which is connected via a converter.
Using a Two-Junction Trigger
Double junction triggers can be used in a DC circuit. They have a high resistance parameter. And they are suitable for different types of starters. Converters in the standard circuit are duplex type. Quite often there are digital analogues that are available in two outputs. Many switches in devices are used with a rectifier. To connect the equipment, the first phase is determined. In this case, the resistance can be at least 45 ohms. With increased conductivity, the lining trigger changes.
Connection via dipole adapter
Dipole adapters are allowed to be connected only through a button post with two buttons: "Start" and "Stop". Triggers are used, as a rule, of low impedance type. If we consider a simple post, then the upper contacts close in the first place. 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. You also need to remember that line triggers are not suitable for starters of this type. The adapter may be connected with an expander. Thus, the overload from the starter is greatly removed. The filter in this case is installed behind the comparator.
Wired switch application
A wired switch can be connected via a transceiver, but only in the first phase. Many controllers are used on two outputs. The expander in this case is used 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 problems with breakdowns in the circuit are detected, the expander is checked.
Connection via module
Only electrode starters can be connected through the module. The posts are selected with a two-button type. In some cases, modules are produced on three outputs. And they have one controller. In this situation, a triode is used to connect. Short-circuit contacts are set in rhinestone in the first phase. It should also be noted that the expander is selected dipole type. If we talk about models with plates, then the closing contacts must be checked for ultimate resistance. The outputs of the expander are thoroughly cleaned. It should also be noted that open contacts are set to zero phase.
