LV-CIR90-40 is a pulse-controlled semi-automatic switching device, designed to control electric power systems allocated in industrial, commercial, or residential settings. This device utilizes switch loops, comprising of a contactor, overload relays, cam timers, photoelectric eyes, and other components. It is used as a bridge between switch-operated load and the switch actuator.

The application field of LV-CIR90-40 covers a broad range of areas. It is mainly used in controlling/monitoring of starting motors, which are used in applications such as ones used in lifts. It can also be used to control electrical lights in commercial and residential areas, and in factories. It can also be used in operating ventilators, compressors, pumps, or other motors that require frequent stopping and starting.

The working principle of LV-CIR90-40 is quite simple and effective. It uses a control circuit consisting of the contactor and overload. A pulse-controlled device transmits energy to the switch-operated load. The timer is the main component of the device. It controls the pulsing frequency and opens and closes the switch contact in response. In the active parts of the switch loop, the current is monitored and the pulse frequency is adjusted accordingly.

The switch-operated load is connected to the contactor through the overload. Using the overload protection, the operator can ensure that the load is correctly matched and does not exceed the required amperage. The current flowing into the load is monitored in case of over-current conditions, and the switch contact is opened or closed when the set amperage is exceeded.

In addition to the overload protection, the LV-CIR90-40 is also equipped with a cam timer, which enables the operator to adjust the frequency of the pulsing signal. This allows to the operator to easily adjust the speed and operation of the switch loop, and to switch and regulate the current quickly in response to changing conditions.

The photoelectric eyes are used to sense changes in the environment and detect when the user is ready to receive power. The user signals the photoelectric eyes, which then activate the switch contact and provide power to the load. This allows the user to discretely and accurately alter the load\'s operating status without having to manually adjust the contactor or overload.

All of these components, when put together, make up the working principle of LV-CIR90-40. This device provides reliable and robust switching and load control solutions, helping to efficiently manage electrical power systems in industrial, commercial, and residential settings.
